I have a saying, “Don’t buy what someone wants to sell you. Buy what you have researched.”

And so I would tell everyone: don’t give brokers discretion over you accounts, and don’t let them convince you to buy unusual bonds, or obscure securities of any sort.  By unusual bonds, I mean structured notes, and eminent men like Joshua Brown and Larry Swedroe encourage the same thing: Don’t buy them.

To the extent that it can, Wall street tries to sell retail investors the exposures that they don’t want.  They offer a higher yield, but take it away and then some if the things that they want to hedge go wrong.  They sell you their problems, and if things go well you are unharmed, but woe betide your capital if things go wrong.

Trust is not owed to financial advisers or brokers.  You need to treat them skeptically; if possible, you need to understand  how they are compensated.  They tend to earn more from securities that are less in the interest of buyers.  (It is not much different from insurance salesmen.)

Wall Street exists to sell promises.  That can take several forms, two of which are:

1) Buy an ownership interest in this promising company.  It’s the wave of the future.

2) Buy a promise to pay from this company under these conditions, and we will pay you an above average yield.

Wall Street knows more than you.  They may make occasional mistakes, some of them big, but compared to retail investors, they know far more.  They profit off of retail investors.  You are the natural resources that they mine.

So why play with them?  If you are using a broker, it is time to end your relationship there, and work with someone who has to put your interests first.  Look for someone who is required to put your interests first.

It’s not as if investment advisors like me always succeed; we don’t.  But the best of us do avoid greed and fear, and so protect investors from their worst instincts — selling low, and buying high.

Take control of your investing, and if you can’t do it yourself, find a talented person with self control who can.

Presently, I have four ways of sourcing buy ideas in the stock market.  Here they are:

1) I read widely, and when I see something interesting, I either jot it down, or hit the “print” button.  I put it in the pile for the quarterly portfolio reshaping.

2) Preston Athey gave me this idea.  I set up a bunch of Googlebots to let me know when a CEO leaves a firm.  For companies with a lot of underused assets, that can be an incredible catalyst to unlock value.  Print, add to pile.

3) My industry studies produce a list of out of favor companies with better prospects than most — the challenge is to separate out the “buggy whip” industries, from those that are genuinely cheap.

4) Finally, I study 13Fs, and try to understand what bright investors are holding and buying.

After I assemble all of the companies that might be worthy investments, I try to forget where I got the idea from.  That forces me to analyze the company my own way, and not merely trust someone or some method that I think is bright.

After that, I engage Portfolio Rule Eight, and make my current portfolio holdings compete against the new ideas.  This is a much better way, a more businesslike way to choose companies to buy.  It forces managers to make explicit decisions that improve the characteristics of the portfolio, improving the probability of winning.

Do you have better ways of sourcing ideas?  If so, leave them in the comments.
