In that, we agreed with Andrew Carnegie, who said that huge fortunes that flow in large part from society should in large part be returned to society. In my case, the ability to allocate capital would have had little utility unless I lived in a rich, populous country in which enormous quantities of marketable securities were traded and were sometimes ridiculously mispriced. And fortunately for me, that describes the U.S. in the second half of the last century.
Long ago, Sir Isaac Newton gave us three laws of motion, which were the work of genius. But Sir Isaac's talents didn't extend to investing: He lost a bundle in the South Sea Bubble, explaining later, 'I can calculate the movement of the stars, but not the madness of men.' If he had not been traumatized by this loss, Sir Isaac might well have gone on to discover the Fourth Law of Motion: For investors as a whole, returns decrease as motion increases.
The problem with commodities is that you are betting on what someone else would pay for them in six months. The commodity itself isn't going to do anything for you....it is an entirely different game to buy a lump of something and hope that somebody else pays you more for that lump two years from now than it is to buy something that you expect to produce income for you over time.
There is no question that an important service is provided to investors by investment companies, investment advisors, trust departments, etc. This service revolves around the attainment of adequate diversification, the preservation of a long-term outlook, the ease of handling investment decisions and mechanics, and most importantly, the avoidance of the patently inferior investment techniques which seem to entice some individuals.
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.
If you don’t feel comfortable making a rough estimate of the asset’s future earnings, just forget it and move on. No one has the ability to evaluate every investment possibility. But omniscience isn’t necessary; you only need to understand the actions you undertake.
Nevertheless, as circumstances presently appear, I feel substantially greater size is more likely to harm future results than to help them. This might not be true for my own personal results, but it is likely to be true for your results.
As I have mentioned before, we cannot make the same sort of money out of permanent ownership of controlled businesses that can be made from buying and reselling such businesses, or from skilled investment in marketable securities. Nevertheless, they offer a pleasant long term form of activity (when conducted in conjunction with high grade, able people) at satisfactory rates of return.
The commission of the investment sins listed above is not limited to 'the little guy.' Huge institutional investors, viewed as a group, have long underperformed the unsophisticated index-fund investor who simply sits tight for decades. A major reason has been fees: Many institutions pay substantial sums to consultants who, in turn, recommend high-fee managers. And that is a fool's game.
Wild swings in share prices have more to do with the "lemming- like" behaviour of institutional investors than with the aggregate returns of the company they own.
