The Wall Street Journal recent had an article, What You Know About Retirement Investing Is Wrong, where it recommended that elderly people invest more in stocks as they get older.? I think the advice is wrong, unless you understand it this way:

Stocks are longer assets than bonds.? Use your bonds to pay for your spending in the early years of your retirement, and don’t sell your stocks.? Once you run out of bonds, start selling your stocks, if the dividend income isn’t enough to live on.

But even 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.

Asset allocation is more difficult than it is 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?

If long-dated, volatile asset classes offer great returns looking forward, but the client has a short time horizon, he can’t invest much in risk assets.

If long-dated, volatile asset classes offer great returns looking forward, but the client has a long time horizon, he can invest a lot in risk assets.

If long-dated, volatile asset classes offer poor returns looking forward, but the client has a short time horizon, he should stay in safe assets.

If long-dated, volatile asset classes offer poor returns looking forward, but the client has a long time horizon, he should stay in safe assets.

Stocks do tend to do well over the long run, but few of us live in environments where that growth is uniform.? The stock market zigs, zags, booms, and busts.? What if it busts when your are old?

Personally, I think it is wiser to maintain a more balanced investment posture in retirement, because the future is not predictable.
