What I am going to write here is half of my summary of how Asset Allocation is done.  Most of this will be done in the context of personal finance, because it is the most complex case, though this paradigm is sufficiently general that it can be applied to any entity.

Good asset allocation, and financial planning generally, focuses on two main questions:

  • When will the cash be needed for expenses?
  • What are the likely returns being offered by asset classes over the planning horizon at every period in which cash will be needed?  Also, how likely are those returns?

Tonight I am writing about the first question.  For institutions, there are typically two solutions — there is a spending rule for endowments, whereas for defined benefit pension plans and other types of employee benefit plans, the actuaries will sit down and estimate future cash needs, and when the needs will take place.  (The same applies to financial institutions, though for institutions with short-term funding profiles, you won’t typically use actuaries, not that you couldn’t.)

For individuals and families, the issues come down to needs, wants, dreams, and risks.  As for risks, you can look at the earliest series at my blog, [summary here] which was on personal finance.  (I never intended to write much on personal finance, and so that was a summary set to get my main ideas out.)

Then comes the hierarchy of expense: needs, wants, and dreams.  Aim to satisfy each one successively.  Some people can only afford needs, others can get to wants, and a few others can get to dreams.  Now, that’s an oversimplification, because many people will reshape their wants and dreams to fit their cost structure.  Happiness is frequently a choice, rather than an abundance of goods and experiences.

Regardless, once you have a spending goal, and your main risks are covered, then you have something to shoot for, and asset allocation can begin.  In the process you might come up with a return target to shoot for, which I call Your Personal Required Investment Earnings Rate.  The basic idea is this:

Everybody has a series of longer-term goals that they want to achieve financially, whether it is putting the kids through college, buying a home, retirement, etc.  Those priorities compete with short run needs, which helps to determine how much gets spent versus saved.

To the extent that one can estimate what one can reasonably save (hard, but worth doing), and what the needs of the future will cost, and when they will come due (harder, but worth doing), one can estimate personal contribution and required investment earnings rates.  Set up a spreadsheet with current assets and the likely savings as positive figures, and the future needs as negative figures, with the likely dates next to them.  Then use the XIRR function in Excel to estimate the personal required investment earnings rate [PRIER].

For more, you can read the article, which has a decent amount on whether return needs are reasonable or not.  More on this topic when I try to describe setting asset earnings assumptions, which is decidedly more complex.  Till then.

Investing is difficult. That said, it can be harder still. Let people with little to no training to try to do it for themselves. Sadly, many people get caught in the fear/greed cycle, and show up at the wrong time to buy and/or sell. They get there late, and then their emotions trick them into action. A rational investor would say, “Okay, I missed that move. Where are opportunities now, if there are any at all?”

Investing can be made even more difficult.  Investing reaches its most challenging level when one relies on his investing to meet an anticipated and repeated need for cash outflows.

Institutional investors will say that portfolio decisions are almost always easier when there is more cash flowing in than flowing out.  It means that there is one dominant mode of thought: where to invest new money?  Some attention will be given to managing existing assets — pruning away assets with less potential, but the need won’t be as pressing.

What’s tough is trying to meet a cash withdrawal rate that is materially higher than what can safely be achieved over time, and earning enough consistently to do so.  Doing so as an amateur managing a retirement portfolio is a particularly hard version of this problem.  Let me point out some of the areas where it will be hard:

1) The retiree doesn’t know how long he, his spouse, and anyone else relying on him will live.  Averages can be calculated, but particularly with two people, the odds are that at least one will outlive an average life expectancy.  Can they be conservative enough in their withdrawals that they won’t outlive their assets?

It’s tempting to overspend, and the temptation will get greater when bad events happen that break the budget, whether those are healthcare or other needs.  It is incredibly difficult to avoid paying for an immediate pressing need, when the soft cost is harming your future.  There is every incentive to say, “We’ll figure it out later.”  The odds on that being true will be low.

2) One conservative estimate of what the safe withdrawal rate is on a perpetuity is the yield on the 10-year Treasury Note plus around 1%.  That additional 1% can be higher after the market has gone through a bear market, and valuations are cheap, and as low as zero near the end of a bull market.

That said, most people people with discipline want a simple spending rule, and so those that are moderately conservative choose that they can spend 4%/year of their assets.  At present, if interest rates don’t go lower still, that will likely (60-80% likelihood) work.  But if income needs are greater than that, the odds of obtaining those yields over the long haul go down dramatically.

3) How does a retiree deal with bear markets, particularly ones that occur early in retirement?  Can he and will he reduce his expenses to reflect the losses?  On the other side, during bull markets, will he build up a buffer, and not get incautious during seemingly good times?

This is an easy prediction to make, but after the next bear market, look for a scad of “Our retirement is ruined articles.”  Look for there to be hearings in Congress that don’t amount to much — and if they do amount to much, watch them make things worse by creating R Bonds, or some similarly bad idea.

Academic risk models typically used by financial planners typically don’t do path-dependent analyses.  The odds of a ruinous situation is far higher than most models estimate because of the need for withdrawals and the autocorrelated nature of returns – good returns begets good, and bad returns beget bad in the intermediate term.  The odds of at least one large bad streak of returns on risky assets during retirement is high, and few retirees will build up a buffer of slack assets to prepare for that.

4) Retirees should avoid investing in too many income vehicles; the easiest temptation to give into is to stretch for yield — it is the oldest scam in the books.  This applies to dividend paying common stocks, and stock-like investments like REITs, MLPs, BDCs, etc.  They have no guaranteed return of principal.  On the plus side, they may give capital gains if bought at the right time, when they are out of favor, and reducing exposure when everyone is buying them.  Negatively, all junior debt tends to return worse on average than senior debts.  It is the same for equity-like investments used for income investing.

Another easy prediction to make is that junk bonds and non-bond income vehicles will be a large contributor to the shortfall in asset return in the next bear market, because many people are buying them as if they are magic.  The naive buyers think: all they do is provide a higher income, and there is no increased risk of capital loss.

5) Leaving retirement behind for a moment, consider the asset accumulation process.  Compounding is trickier than it may seem.  Assets must be selected that will grow their value including dividend payments over a reasonable time horizon, corresponding to a market cycle or so (4-8 years).  Growth in value should be in excess of that from expanding stock market multiples or falling interest rates, because you want to compound in the future, and low interest rates and high stock market multiples imply that future compounding opportunities are lower.

Thus, in one sense, there is no benefit much from a general rise in values from the stock or bond markets.  The value of a portfolio may have risen, but at the cost of lower future opportunities.  This is more ironclad in the bond market, where the cash flow streams are fixed.  With stocks and other risky investments, there may be some ways to do better.

Retirees should be aware that the actions taken by one member of a large cohort of retirees will be taken by many of them.  This makes risk control more difficult, because many of the assets and services that one would like to buy get bid up because they are scarce.  Often it may be that those that act earliest will do best, and those arriving last will do worst, but that is common to investing in many circumstances.  As Buffett has said, “What a wise man does in the beginning a fool does in the end.”

6) Retirement investors should avoid taking too much or too little risk. It’s psychologically difficult to buy risk assets when things seem horrible, or sell when everyone else is carefree.  If a person can do that successfully, he is rare.

What is achievable by many is to maintain a constant risk posture.  Don’t panic; don’t get greedy — stick to a moderate asset allocation through the cycles of the markets.

7) With asset allocation, retirees should overweight out-of-favor asset classes that offer above average cashflow yields.  Estimates on these can be found at GMO or Research Affiliates.  They should rebalance into new asset classes when they become cheap.

Another way retirees can succeed would be investing in growth at a reasonable price – stocks that offer capital growth opportunities at an inexpensive price and a margin of safety.  These companies or assets need to have large opportunities in front of them that they can reinvest their free cash flow into.  This is harder to do than it looks.  More companies look promising and do not perform well than those that do perform well.

Yet another way to enhance returns is value investing: find undervalued companies with a margin of safety that have potential to recover when conditions normalize, or find companies that can convert their resources to a better use that have the willingness to do that.  After the companies do well, reinvest in new possibilities that have better appreciation potential.


8 ) Many say that the first rule of markets is to avoid losses.  Here are some methods to remember:

  • Always seek a margin of safety.  Look for valuable assets well in excess of debts, governed by the rule of law, and purchased at a bargain price.
  • For assets that have fallen in price, don’t try to time the bottom — buy the asset when it rises above its 200-day moving average. This can limit risk, potentially buying when the worst is truly past.
  • Conservative investors avoid the areas where the hot money is buying and own assets being acquired by patient investors.

9) As assets shrink, what should be liquidated?  Asset allocation is more difficult than it is described in the textbooks, or in the syllabuses for the CFA Institute or for CFPs.  It is a blend of two things — when does the investor need the money, and what asset classes offer decent risk adjusted returns looking forward?  The best strategy is forward-looking, and liquidates what has the lowest risk-adjusted future return.  What is easy is selling assets off from everything proportionally, taking account of tax issues where needed.

Here’s another strategy that’s gotten a little attention lately: stocks are longer assets than bonds, so use bonds to pay for your spending in the early years of your retirement, and initially don’t sell the stocks.  Once the bonds run out, then start selling stocks if the dividend income isn’t enough to live on.

This idea is weak.  If a person followed this in 1997 with a 10-year horizon, their stocks would be worth less in 2008-9, even if they rocket back out to 2014.

Remember again:

You don’t benefit much from a general rise in values from the stock or bond markets.  The value of your portfolio may have risen, but at the cost of lower future opportunities.

That goes double in the distribution phase. The objective is to convert assets into a stream of income.  If interest rates are low, as they are now, safe income will be low.  The same applies to stocks (and things like them) trading at high multiples regardless of what dividends they pay.

Don’t look at current income.  Look instead at the underlying economics of the business, and how it grows value.  It is far better to have a growing income stream than a high income stream with low growth potential.

Deciding what to sell is an exercise in asset-liability management.  Keep the assets that offer the best return over the period that they are there to fund future expenses.

10) Will Social Security take a hit out around 2026?  One interpretation of the law says that once the trust fund gets down to one year’s worth of payments, future payments may get reduced to the level sustainable by expected future contributions, which is 73% of expected levels.  Expect a political firestorm if this becomes a live issue, say for the 2024 Presidential election.  There will be a bloc of voters to oppose leaving benefits unchanged by increasing Social Security taxes.

Even if benefits last at projected levels longer than 2026, the risk remains that there will be some compromise in the future that might reduce benefits because taxes will not be raised.  This is not as secure as a government bond.

11) Be wary of inflation, but don’t overdo it.  The retirement of so many people may be deflationary — after all, look at Japan and Europe so far.  Economies also work better when there is net growth in the number of workers.  It will be tempting for policymakers to shrink what liabilities they can shrink through inflation, but there will also be a bloc of voters to oppose that.

Also consider other risks, and how assets may fare.  Retirees should analyze what exposure they have to:

  • Deflation and a credit crisis
  • Expropriation
  • Regulatory change
  • Trade wars
  • Changes in taxes
  • Asset illiquidity
  • Reductions in reimbursement from government programs like Medicare, Medicaid, etc.
  • And more…

12) Retirees need a defender of two against slick guys who will try to cheat them when they are older.  Those who have assets are a prime target for scams.  Most of these come dressed in suits: brokers and other investment salesmen with plausible ways to make assets stretch further.  But there are other scams as well — retirees should run everything significant past a smart younger person who is skeptical, and knows how to say no when it is necessary.


Some will think this is unduly dour, but this is realistic.  There are not enough resources to give all of the Baby Boomers a lush retirement, without unduly harming younger age cohorts, and this is true over most of the developed world, not just the US.

Even with skilled advisers helping, retirees need to be ready for the hard choices that will come up. They should think through them earlier rather than later, and take some actions that will lower future risks.

The basic idea of retirement investing is how to convert present excess income into a robust income stream in retirement.  Managing a pile of assets for income to live off of is a challenge, and one that most people are not geared up for, because poor planning and emotional decisions lead to subpar results.

Retirees should aim for the best future investment opportunities with a margin of safety, and let the retirement income take care of itself.  After all, they can’t rely on the markets or the policymakers to make income opportunities easy.


I am generally not a fan of formulaic books on investing, and this is particularly true of books that take unusual approaches to investing. This book is an exception because it does nothing unusual, and follows what all good quantitative investors know have worked in the past.  The past is not a guarantee of the future, but if the theories derived from past data make sense from what we know about human nature, that’s about as good as we can get.

The book begins with a critique of the abilities of financial advisors — their fees, asset allocation, and security selection.  It then shows how models of financial markets outperform most financial advisors.

Then, to live up to its title , the book gives simple versions of models that can be applied by individuals that would have outperformed the markets in the past.  You can beat the markets, lower risk, and “Do It Yourself [DIY].”  It provides models for asset allocation, stock selection, and risk control, simple enough that a motivated person with math skills equal to the first half of Algebra 1 could apply them in a moderate amount of time per month.  It also provides a simpler version of the full model that omits the security selection for stocks.

The book closes by offering three reasons why people won’t follow the book and do it themselves: fear of failure, inertia, and not wanting to give up an advisor who is a friend.  It also offers three risks for the DIY investor — overconfidence, the desire to be a hero (seems to overlap with overconfidence), and that the theories may be insufficient for future market behavior.

This is where I have the greatest disagreement with the book.  I interact with a lot of people.  Most of them have no interest in learning the slightest bit about investing.  Some have some inclination to learn about investing, but even the simple models of the book would make their heads spin, or they just wouldn’t want to take the time to do it.  Some of it is similar to seeing a Youtube video on draining and refilling your automatic transmission fluid.  You might watch it, and say “I think I get it,” but the costs of making a mistake are sufficiently severe that you might not want to do it without an expert by your side.  Most will take it to the repair garage and pay up.

I put a knife to my own throat as I write this, as I am an investment advisor, but there is more specialized knowledge in the hands of an auto mechanic than in an investment advisor, and the risk of loss is lower to manage your own money than to fix your own brakes.  That said, enough people after reading the book will say to themselves, “This is just one author, and I barely understand the performance tables in the book — if right, am I capable of doing this?  Or, could it be wrong?  I can’t verify it myself.”

The book isn’t wrong.  If you are willing to put in the time to follow the instructions of the authors, I think you will do better than most.  My sense is that the grand majority people are not willing to do that.  They don’t have the time or inclination.



The book could have been clearer on the ROBUST method for risk control.  It took me a bit of effort to figure out that the two submodels share half of the weight, so that when submodels A & B flash green — 100% weight, one green and one red — 50% weight, both red — 0% weight.

Also, the book is enhanced by the security selection model for stocks, but how many people would have the assets to assemble and maintain a portfolio with sufficient diversification?  The book might have been cleaner and simpler to leave that out.  The last models of the book don’t use it anyway.

Summary / Who Would Benefit from this Book

I liked this book, and I recommend it for those who are willing to put in the time to implement its ideas.  This is not a book for beginners, and you have to be comfortable with the small amount of math and the tables of financial statistics, unless you are willing to trust them blindly.  (Or trust me when I say that they are likely accurate.)

But with the caveats listed above, it is a good book for people who are motivated to do better with their investments.  If you want to buy it, you can buy it here: DIY Financial Advisor.

Full disclosure: I received a copy from one of the authors, a guy for whom I have respect.

If you enter Amazon through my site, and you buy anything, I get a small commission.  This is my main source of blog revenue.  I prefer this to a “tip jar” because I want you to get something you want, rather than merely giving me a tip.  Book reviews take time, particularly with the reading, which most book reviewers don’t do in full, and I typically do. (When I don’t, I mention that I scanned the book.  Also, I never use the data that the PR flacks send out.)

Most people buying at Amazon do not enter via a referring website.  Thus Amazon builds an extra 1-3% into the prices to all buyers to compensate for the commissions given to the minority that come through referring sites.  Whether you buy at Amazon directly or enter via my site, your prices don’t change.

An investor can and should learn from the past.  He should never react to the recent past.  Why?  The past can’t be changed, but it can be known.  Reacting to the recent past leads investors into the valleys of greed and regret — good investments missed, bad investments incurred.

We’ve been in a relatively volatile environment for the last two weeks or so.  Markets are down, with a lot of noise over China, and slowing global growth.  Boo!

The markets were too complacent for too long, and valuations were/are higher than they should be, given current earnings, growth prospects and corporate bond yields.  It’s not the best environment for stocks given those longer-term valuation factors, but guess what?  The market often ignores those until a crisis hits.

The FOMC is going to tighten monetary policy soon.  Boo!

The things that people are taking on as worries rarely produce large crises.  They could mark stocks down 20-30% from the peak, producing a bear market, but they are unlikely of themselves to produce something similar to 2000-2 or 2008-9.

Let’s think about a few things supporting valuations and suppressing yields at present.  The overarching demographic trend in the market leads to a fairly consistent bid for risky assets.  It would take a lot to derail that bid, though that has happened twice in the last 15 years.  Ask yourself, do we face some significant imbalance where the banks could be impaired? I don’t see it at present.  Is a major sector like information technology or healthcare dramatically overvalued?  Maybe a little overvalued, but not a lot in relative terms.

There are major elections coming up next year, and a group of politicians harmful to the market will be elected.  This is a bad part of the Presidential Cycle.  Boo!

Take a step back, and ask how you would want your portfolio positioned for a moderate pullback, where you can’t predict how long it will take or last.  Also ask how you would like to be positioned for the market to return to its recent highs over the next year.  Come up with your own estimates of likelihood for these scenarios, and others that you might imagine.

We work in a fog.  We don’t know the future at all, but we can take actions to affect it, and our investing results.  The trouble is, we can adjust our risk profile, but our ability to know when it is wise to take more or less risk is poor, except perhaps at market extremes.  Even then, we don’t act, because we drink the Kool-aid in those ebullient or depressed environments.  We often know what we should do at the extremes, but we don’t listen.  There is a failure of the will.

This is a bad season of the year.  September and October are particularly bad months.  Boo!

I often say that there is always enough time to panic.  Well, let me modify that: there’s also always enough time to plan.  But what will you take as inputs to your plan?  Look at your time horizon, and ask what investment factors will persistently change over that horizon.  There are factors that will change, but can you see any that are significant enough for you to notice, and obscure enough that much of the rest of the market has missed it?

Yeah, that’s tough to do.  So perhaps be modest in your risk positioning, and invest with a margin of safety for the intermediate-to-long-term, recognizing that in most cases, the worst case scenario does not persist.  The Great Depression ended.  So did the ’70s.  Valuations are higher now than in 2007.  (Tsst… Boo!)  The crisis in 2008-9 did not persist.

That doesn’t mean a crisis could not persist, just that it is unlikely.  Capitalist systems are very good at dealing with economic volatility, even amid moderate socialism.  Go ahead and ask, “Will we become like Greece?  Argentina?  Venezuela?  Russia?  Spain?  Etc?”  Boo!

It would take a lot to get us to the economic conditions of any of those places.  Thus I would say it is reasonable to take moderate risk in this environment if your time horizon and stomach/sleep allow for it.  That doesn’t mean you won’t go through a bear market in the future, but it will be unlikely for that bear market to last beyond two years, and even less likely a decade.

I ran across two interesting articles today:

Both articles are exercises in understanding the time horizon over which you invest.  If you are older, you may not have the time to recover from market shortfalls, so advice to buy dips may sound hollow when you are nearer to drawing on your assets.

Thus the idea that volatility, presumably negative, doesn’t hurt unless you sell.  Some people don’t have much choice in the matter.  They have retired, and they have a lump sum of money that they are managing for long-term income.  No more money is going in, money is only going out.  What can you do?

You have to plan before volatility strikes.  My equity only clients had 14% cash before the recent volatility hit.  Over the past week I opportunistically brought that down to 10% in names that I would like to own even if the “crisis” deepened.  That flexibility was built into my management.  (If the market recovers enough, I will rebuild the buffer.  Around 1300 on the S&P, I would put all cash to work, and move to the alternative portfolio management strategy where I sell the most marginal ideas one at a time to raise cash and reinvest into the best ideas.)

If an older investor would be hurt by a drawdown in the stock market, he needs to invest less in stocks now, even if that means having a lower income on average over the longer-term.  With a higher level of bonds in the portfolio, he could more than proportionately draw down on bonds during a crisis, which would rebalance his portfolio.  If and when the stock market recovered, for a time, he could draw on has stock positions more than proportionately then.  That also would rebalance the portfolio.

Again, plans like that need to be made in advance.  If you have no plans for defense, you will lose most wars.

One more note: often when we talk about time horizon, it sounds like we are talking about a single future point in time.  When the time for converting assets to cash is far distant, using a single point may be a decent approximation.  When the time for converting assets to cash is near, it must be viewed as a stream of payments, and whatever scenario testing, (quasi) Monte Carlo simulations, and sensitivity analyses are done must reflect that.

Many different scenarios may have the same average rate of return, but the ones with early losses and late gains are pure poison to the person trying to manage a lump sum in retirement.  The same would apply to an early spike in inflation rates followed by deflation.

The time to plan is now for all contingencies, and please realize that this is an art and not a science, so if someone comes to you with glitzy simulation analyses, ask them to run the following scenarios: run every 30-year period back as far as the data goes.  If it doesn’t include the Great Depression, it is not realistic enough.  Run them forwards, backwards, upside-down forwards, and upside-down backwards.  (For the upside-down scenarios normalize the return levels to the right side up levels.)  The idea here is to use real volatility levels in the analyses, because reality is almost always more volatile than models using normal distributions.  History is meaner, much meaner than models, and will likely be meaner in the future… we just don’t know how it will be meaner.

You will then be surprised at how much caution the models will indicate, and hopefully those who can will save more, run safer asset allocations, and plan to withdraw less over time.  Reality is a lot more stingy than the models of most financial Dr. Feelgoods out there.

One more note: and I know how to model this, but most won’t — in the Great Depression, the returns after 1931 weren’t bad.  Trouble is, few were able to take advantage of them because they had already drawn down on their investments.  The many bankruptcies meant there was a smaller market available to invest in, so the dollar-weighted returns in the Great Depression were lower than the buy-and-hold returns.  They had to be lower, because many people could not hold their investments for the eventual recovery.  Part of that was margin loans, part of it was liquidating assets to help tide over unemployment.

It would be wonky, but simulation models would have to have an uptick in need for withdrawals at the very time that markets are low.  That’s not all that much different than some had to do in the recent financial crisis.  Now, who is willing to throw *that* into financial planning models?

The simple answer is to be more conservative.  Expect less from your investments, and maybe you will get positive surprises.  Better that than being negatively surprised when older, when flexibility is limited.

One of my clients asked me what I think is a hard question: When should I deploy capital?  I’ll try to answer that here.

There are three main things to consider in using cash to buy or sell assets:

  • What is your time horizon?  When will you likely need the money for spending purposes?
  • How promising is the asset in question?  What do you think it might return vs alternatives, including holding cash?
  • How safe is the asset in question?  Will it survive to the end of your time horizon under almost all circumstances and at least preserve value while you wait?

Other questions like “Should I dollar cost average, or invest the lump?” are lesser questions, because what will make the most difference in ultimate returns comes from  the above three questions.  Putting it another way, the results of dollar cost averaging depend on returns after you put in the last dollar of the lump, as does investing the lump sum all at once.

Thinking about price momentum and mean-reversion are also lesser matters, because if your time horizon is a long one, the initial results will have a modest effect on the ultimate results.

Now, if you care about price momentum, you may as well ignore the rest of the piece, and start trading in and out with the waves of the market, assuming you can do it.  If you care about mean reversion, you can wait in cash until we get “the mother of all selloffs” and then invest.  That has its problems as well: what’s a big enough selloff?  There are a lot of bears waiting for rock bottom valuations, but the promised bargain valuations don’t materialize because others invest at higher prices than you would, and the prices never get as low as you would like.  Ask John Hussman.

Investing has to be done on a “good enough” basis.  The optimal return in hindsight is never achieved.  Thus, at least for value investors like me, we focus on what we can figure out:

  • How long can I set aside this capital?
  • Is this a promising investment at a relatively attractive price?
  • Do I have a margin of safety buying this?

Those are the same questions as the first three, just phrased differently.

Now, I’m not saying that there is never a time to sit on cash, but decisions like that are typically limited to times where valuations are utterly nuts, like 1964-5, 1968, 1972, 1999-2000 — basically parts of the go-go years and the dot-com bubble.  Those situations don’t last more than a decade, and are typically much shorter.

Beyond that, if you have the capital to spare, and the opportunity is safe and cheap, then deploy the capital.  You’ll never get it perfect.  The price may fall after you buy.  Those are the breaks.  If that really bothers you, then maybe do half of what you would ultimately do, but set a time limit for investment of the other half.  Remember, the opposite can happen, and the price could run away from you.

A better idea might show up later.  If there is enough liquidity, trade into the new idea.

Since perfection is not achievable, if you have something good enough, I recommend that you execute and deploy the capital.  Over the long haul, given relative peace, the advantage belongs to the one who is invested.

If you still wonder about this question you can read the following two articles:

In the end, there is no perfect answer, so if the situation is good enough, give it your best shot.


I’m not going to argue for any particular strategy here. My main point is this: every valid strategy is going to have some periods of underperformance.  Don’t give up on your strategy because of that; you are likely to give up near the point of maximum pain, and miss the great returns in the bull phase of the strategy.

Here are three simple bits of advice that I hand out to average people regarding asset allocation:

  1. Figure out what the maximum loss is that you are willing to take in a year, and then size your allocation to risky assets such that the likelihood of exceeding that loss level is remote.
  2. If you have any doubts on bit of advice #1, reduce the amount of risky assets a bit more.  You’d be surprised how little you give up in performance from doing so.  The loss from not allocating to risky assets that return better on average is partly mitigated by a bigger payoff from rebalancing from risky assets to safe, and back again.
  3. Use additional money slated for investing to rebalance the portfolio.  Feed your losers.

The first rule is most important, because the most important thing here is avoiding panic, leading to selling risky assets when prices are depressed.  That is the number one cause of underperformance for average investors.  The second rule is important, because it is better to earn less and be able to avoid panic than to risk losing your nerve.  Rule three just makes it easier to maintain your portfolio; it may not be applicable if you follow a momentum strategy.

Now, about momentum strategies — if you’re going to pursue strategies where you are always buying the assets that are presently behaving strong, well, keep doing it.  Don’t give up during the periods where it doesn’t seem to work, or when it occasionally blows up.  The best time for any strategy typically come after a lot of marginal players give up because losses exceed their pain point.

That brings me back to rule #1 above — even for a momentum strategy, maybe it would be nice to have some safe assets on the side to turn down the total level of risk.  It would also give you some money to toss into the strategy after the bad times.

If you want to try a new strategy, consider doing it when your present strategy has been doing well for a while, and you see new players entering the strategy who think it is magic.  No strategy is magic; none work all the time.  But if you “harvest” your strategy when it is mature, that would be the time to do it.  It would be similar to a bond manager reducing exposure to risky bonds when the additional yield over safe bonds is thin, and waiting for a better opportunity to take risk.

But if you do things like that, be disciplined in how you do it.  I’ve seen people violate their strategies, and reinvest in the hot asset when the bull phase lasts too long, just in time for the cycle to turn.  Greed got the better of them.

Markets are perverse.  They deliver surprises to all, and you can be prepared to react to volatility by having some safe assets to tone things down, or, you can roll with the volatility fully invested and hopefully not panic.  When too many unprepared people are fully invested in risky assets, there’s a nasty tendency for the market to have a significant decline.  Similarly, when people swear off investing in risky assets, markets tend to perform really well.

It all looks like a conspiracy, and so you get a variety of wags in comment streams alleging that the markets are rigged.  The markets aren’t rigged.  If you are a soldier heading off for war, you have to mentally prepare for it.  The same applies to investors, because investing isn’t perfectly easy, but a lot of players say that it is easy.

We can make investing easier by restricting the choices that you have to make to a few key ones.  Index funds.  Allocation funds that use index funds that give people a single fund to buy that are continually rebalanced.  But you would still have to exercise discipline to avoid fear and greed — and thus my three example rules above.

If you need more confirmation on this, re-read my articles on dollar-weighted returns versus time-weighted returns.  Most trading that average people do loses money versus buying and holding.  As a result, the best thing to do with any strategy is to structure it so that you never take actions out of a sense of regret for past performance.

That’s easy to say, but hard to do.  I’m subject to the same difficulties that everyone else is, but I worked to create rules to limit my behavior during times of investment pain.

Your personality, your strategy may differ from mine, but the successful meta-strategy is that you should be disciplined in your investing, and not give into greed or panic.  Pursue that, whether you invest like me or not.

My last post has many implications. I want to make them clear in this post.

  1. When you analyze a manager, look at the repeatability of his processes.  It’s possible that you could get “the Big Short” right once, and never have another good investment idea in your life.  Same for investors who are the clever ones who picked the most recent top or bottom… they are probably one-trick ponies.
  2. When a manager does well and begins to pick up a lot of new client assets, watch for the period where the growth slows to almost zero.  It is quite possible that some of the great performance during the high growth period stemmed from asset prices rising due to the purchases of the manager himself.  It might be a good time to exit, or, for shorts to consider the assets with the highest percentage of market cap owned as targets for shorting.
  3. Often when countries open up to foreign investment, valuations are relatively low.  The initial flood of money in often pushes up valuations, leads to momentum buyers, and a still greater flow of money.  Eventually an adjustment comes, and shakes out the undisciplined investors.  But, when you look at the return series analyze potential future investment, ignore the early years — they aren’t representative of the future.
  4. Before an academic paper showing a way to invest that would been clever to use in the past gets published, the excess returns are typically described as coming from valuation, momentum, manager skill, etc.  After the paper is published, money starts getting applied to the idea, and the strategy will do well initially.  Again, too much money can get applied to a limited factor (or other) anomaly, because no one knows how far it can get pushed before the market rebels.  Be careful when you apply the research — if you are late, you could get to hold the bag of overvalued companies.  Aside for that, don’t assume that performance from the academic paper’s era or the 2-3 years after that will persist.  Those are almost always the best years for a factor (or other) anomaly strategy.
  5. During a credit boom, almost every new type of fixed income security, dodgy or not, will look like genius by the early purchasers.  During a credit bust, it is rare for a new security type to fare well.
  6. Anytime you take a large position in an obscure security, it must jump through extra hoops to assure a margin of safety.  Don’t assume that merely because you are off the beaten path that you are a clever contrarian, smarter than most.
  7. Always think about the carrying capacity of a strategy when you look at an academic paper.  It might be clever, but it might not be able to handle a lot of money.  Examples would include trying to do exactly what Ben Graham did in the early days today, and things like Piotroski’s methods, because typically only a few small and obscure stocks survive the screen.
  8. Also look at how an academic paper models trading and liquidity, if they give it any real thought at all.  Many papers embed the idea that liquidity is free, and large trades can happen where prices closed previously.
  9. Hedge funds and other manager databases should reflect that some managers have closed their funds, and put them in a separate category, because new money can’t be applied to those funds.  I.e., there should be “new money allowed” indexes.
  10. Max Heine, who started the Mutual Series funds (now part of Franklin), was a genius when he thought of the strategy 20% distressed investing, 20% arbitrage/event-driven investing and 60% value investing.  It produced great returns 9 years out of 10.  but once distressed investing and event-driven because heavily done, the idea lost its punch.  Michael Price was clever enough to sell the firm to Franklin before that was realized, and thus capitalizing the past track record that would not do as well in the future.
  11. The same applies to a lot of clever managers.  They have a very good sense of when their edge is getting dulled by too much competition, and where the future will not be as good as the past.  If they have the opportunity to sell, they will disproportionately do so then.
  12. Corporate management teams are like rock bands.  Most of them never have a hit song.  (For managements, a period where a strategy improves profitability far more than most would have expected.)  The next-most are one-hit wonders.  Few have multiple hits, and rare are those that create a culture of hits.  Applying this to management teams — the problem is if they get multiple bright ideas, or a culture of success, it is often too late to invest, because the valuation multiple adjusts to reflect it.  Thus, advantages accrue to those who can spot clever managements before the rest of the market.  More often this happens in dull industries, because no one would think to look there.
  13. It probably doesn’t make sense to run from hot investment idea to hot investment idea as a result of all of this.  You will end up getting there once the period of genius is over, and valuations have adjusted.  It might be better to buy the burned out stuff and see if a positive surprise might come.  (Watch margin of safety…)
  14. Macroeconomics and the effect that it has on investment returns is overanalyzed, though many get the effects wrong anyway.  Also, when central bankers and politicians take cues from the prices of risky assets, the feedback loop confuses matters considerably.  if you must pay attention to macro in investing, always ask, “Is it priced in or not?  How much of it is priced in?”
  15. Most asset allocation work that relies on past returns is easy to do and bogus.  Good asset allocation is forward-looking and ignores past returns.
  16. Finally, remember that some ideas seem right by accident — they aren’t actually right.  Many academic papers don’t get published.  Many different methods of investing get tried.  Many managements try new business ideas.  Those that succeed get air time, whether it was due to intelligence or luck.  Use your business sense to analyze which it might be, or, if it is a combination.

There’s more that could be said here.  Just be cautious with new investment strategies, whatever form they may take.  Make sure that you maintain a margin of safety; you will likely need it.

I was writing to potential clients when I realized that I don’t have so much to write about my bond track record as I do my track record with stocks.  I jotted down a note to formalize what I say about my bond portfolios.

One person I was writing to asked some detailed questions, and I told him that the stock market was likely to return about 4.5%/yr (not adjusted for inflation) over the next ten years.  The model I use is the same one as this one used by pseudonymous Philosophical Economist.  I don’t always agree with him, but he’s a bright guy, what can I say?  That’s not a very high return — the historical average is around 9.5%.  The market is in the 85th-90th percentiles of valuation, which is pretty high.  That said, I am not taking any defensive action yet.


But then it hit me.  The yield on my bond portfolio is around 4.5% also.  Now, it’s not a riskless bond portfolio, as you can tell by the yield.  I’m no longer running the portfolio described in Fire and Ice.  I sold the long Treasuries about 30 basis points ago.  Right now, I am only running the Credit sensitive portion of the portfolio, with a bit of foreign bonds mixed in.

Why am I doing this?  I think it has a good balance of risks.  Remember that there is no such thing as generic risk.  There are many risks.  At this point this portfolio has a decent amount of credit risk, some foreign exchange risk, and is low in interest rate risk.  The duration of the portfolio is less than 2, so I am not concerned about rising rates, should the FOMC ever do such a thing as raise rates.  (Who knows?  The economy might actually grow faster if they did that.  Savers will eventually spend more.)

But 10 years is a long time for a bond portfolio with a duration of less than 2 years.  I’m clipping coupons in the short run, running credit risk while I don’t see any major credit risks on the horizon aside from weak sovereigns (think the PIIGS), student loans, and weak junk (ratings starting with a “C”).  The risks on bank loans are possibly overdone here, even with weakened covenants.  Aside from that, if we really do see a lot of credit risk crop up, stocks will get hit a lot harder than this portfolio.  Dollar weakness and US inflation (should we see any) would also not be a risk.

I’ve set a kind of a mental stop loss at losing 5% of portfolio value.  Bad credit is the only significant factor that could harm the portfolio.  If credit problems got that bad, it would be time to exit because credit problems come in bundles, not dribs and drabs.

I’m not doing it yet, but it is tempting to reposition some of my IRA assets presently in stocks into the bond strategy.  I’m not sure I would lose that much in terms of profit potential, and it would increase the overall safety of the portfolio.

I’ll keep you posted.  That is, after I would tell my clients what I am doing, and give them a chance to act, should they want to.

Finally, do you have a different opinion?  You can email me, or, you can share it with all of the readers in the comments.  Please do.

Despite the large and seemingly meaty title, this will be a short piece.  I class these types of investors together because most of them have long investment horizons.  From an asset-liability management standpoint, that would mean they should invest similarly.  That may be have been true for Defined Benefit [DB] pension plans and Endowments, but that has shifted over time, and is increasingly not true.  In some ways, the DB plans are becoming more like life insurers in the way they invest, though not totally so.  So, why do they invest differently?  Two reasons: internal risk management goals, and the desires of insurance regulators to preserve industry solvency.

Let’s start with life insurers.  Regulators don’t want insolvent companies, so they constrain companies into safe assets using risk-based capital charges.  The riskier the investment, the more capital the insurer has to put up against it.  After that, there is cash-flow testing which tends to push life insurers to match assets and liabilities, or at least, not have a large mismatch.  Also, accounting rules may lead insurers to buy assets where the income will show up on their financial statements regularly.

The result of this is that life insurers don’t invest much in risk assets — maybe they invest in stocks, junk bonds, etc. up to the amount of their surplus, but not much more than that.

DB plans don’t have regulators that care about investment risks.  They do have plan sponsors that do care about investment risk, and that level of care has increased over the past 15 years.  Back in the late ’90s it was in vogue for DB plans to allocate more and more to risk assets, just in time for the market to correct.  (Note to retail investors: professionals may deride your abilities, but the abilities of many professionals are questionable also.)

Over that time, the rate used to discount DB plan liabilities became standardized and attached to long high quality bonds.  Together with a desire to minimize plan funding risks, and thus corporate risks for the plan sponsor, that led to more investments in bonds, and less in equities and other risk assets.  Some plans try to cash flow match expected future plan payments out to a horizon.

Finally, endowments have no regulator, and don’t have a plan sponsor that has to make future payments.  They are free to invest as they like, and probably have the highest degree of variation in their assets as a group.  There is some level of constraint from the spending rules employed by the endowments, particularly since 2008-9, when a number of famous endowments came to realize that there was a liability structure behind them when they ran low on liquidity amid the crisis. [Note: long article.]  You might think it would be smart to have the present value of 3-5 years of expenditures on hand in bonds, but that is not always the case.  In some ways, the quick recovery taught some endowment investors the wrong lesson — that they could wait out any crisis.

That’s my quick summary.  If you have thoughts on the matter, you can share them in the comments.
