Observing that the market was FREQUENTLY efficient, EMT Adherents went on to conclude incorrectly that it was ALWAYS efficient. The difference between these propositions is night and day.
A prediction about the direction of the stock market tells you nothing about where stocks are headed, but a whole lot about the person doing the predicting.
Interest rates are to asset prices what gravity is to the apple. When there are low interest rates, there is a very low gravitational pull on asset prices.
We are trading away a little bit of our country all the time for this access consumption that we have over what we've produced. That is not good. I think it's terrible over time. But our country's productive grows enough so we actually can do that, and we'll still be better off. We just don't be as well off as if we hadn't done it.
I bought my first stock in 1942, in the summer of '42. I was 11 years old. And so 75 years have gone by. And I have never known what the market's going to do the next day. And that's not my game. My game is to decide whether I'm in the right economy, which America's definitely been ever since that time. The Dow has gone from 100 to 21,000 during that time. And no matter what the headlines say, or terrible things are happening - we were losing the war in the Pacific when I first bought stocks.
We rarely use much debt and, when we do, we attempt to structure it on a long-term fixed rate basis. We will reject interesting opportunities rather than over-leverage our balance sheet. This conservatism has penalized our results but it is the only behavior that leaves us comfortable, considering our fiduciary obligations to policyholders, depositors, lenders and the many equity holders who have committed unusually large portions of their net worth to our care.
The optimum portfolio depends on the various expectations of choices available and the degree of variance in performance which is tolerable. The greater the number of selections, the less will be the average year-to-year variation in actual versus expected results. Also, the lower will be the expected results, assuming different choices have different expectations of performance.
My net worth is the market value of holdings less the tax payable upon sale. The liability is just as real as the asset unless the value of the asset declines (ouch), the asset is given away (no comment), or I die with it. The latter course of action would appear to at least border on a Pyrrhic victory.
The speed at which a business success is recognized, furthermore, is not that important as long as the company's intrinsic value is increasing at a satisfactory rate. In fact, delayed recognition can be an advantage: It may give us the chance to buy more of a good thing at a bargain price.
If you know how to value businesses, it's crazy to own 50 stocks or 40 stocks or 30 stocks, probably because there aren't that many wonderful businesses understandable to a single human being in all likelihood. To forego buying more of some super-wonderful business and instead put your money into #30 or #35 on your list of attractiveness just strikes Charlie and me as madness.
