Investors should be skeptical of history-based models. Constructed by a nerdy-sounding priesthood using esoteric terms such as beta, gamma, sigma and the like, these models tend to look impressive. Too often, though, investors forget to examine the assumptions behind the models. Beware of geeks bearing formulas.
Ben's Mr. Market allegory may seem out-of-date in today's investment world, in which most professionals and academicians talk of efficient markets, dynamic hedging and betas. Their interest in such matters is understandable, since techniques shrouded in mystery clearly have value to the purveyor of investment advice. After all, what witch doctor has ever achieved fame and fortune by simply advising 'Take two aspirins'?
If you have more than 120 or 130 I.Q. points, you can afford to give the rest away. You don't need extraordinary intelligence to succeed as an investor.
When the president of the United States goes out at, you know, 8:00 o'clock in the morning and then his own party votes gets him 2 to 1 in the house, you know that somehow a message isn't getting out. It takes real leadership.
One of the ironies of the stock market is the emphasis on activity.

A hyperactive stock market is the pick pocket of enterprise.
We will continue to ignore political and economic forecasts, which are an expensive distraction for many investors and
businessmen. Thirty years ago, no one could have foreseen the huge expansion of the Vietnam War, wage and price controls, two oil shocks, the resignation of a president, the dissolution of the Soviet Union, a one-day drop in the Dow of 508 points, or treasury bill yields fluctuating between 2.8% and 17.4%.
Would your reply possibly be this? Well, it all depends on what my tax rate will be on the gain you're saying we're going to make. If the taxes are too high, I would rather leave the money in my savings account, earning a quarter of 1 percent. Only in Grover Norquist's imagination does such a response exist.
I think you should read everything you can. In my case, by the age of 10, I'd read every book in the Omaha public library about investing, some twice.
You need to fill your mind with various competing thoughts and decide which make sense.
