It's my guess that something like 5% of GDP goes to money management and itsattendant friction. I define it broadly - annuities, incentive pay, all trading, etc. Nobody else has used figures that high, but that's my guess. Worst of all, the people doing this are among the best and the brightest. Hundreds and thousands of engineers, etc. are going into hedge funds and investment banking. That is not an intelligent allocation of the brainpower of the civilization.

Intelligent people make decisions based on opportunity costs.

The whole concept of dividing it up into 'value' and 'growth' strikes me as twaddle. It's convenient for a bunch of pension fund consultants to get fees prattling about and a way for one advisor to distinguish himself from another. But, to me, all intelligent investing is value investing.

All intelligent investing is value investing - acquiring more that you are paying for. You must value the business in order to value the stock.

You need to have a passionate interest in why things are happening. That cast of mind, kept over long periods, gradually improves your ability to focus on reality. If you don't have the cast of mind, you're destined for failure even if you have a high I.Q.
