You only need to make one big score in finance to be a hero forever.

You only need to make one big score in finance to be a hero forever.

I should mention that I am a member of the board of directors of Dimensional Fund Advisors.

Everyone recognizes that's a joke because obviously the number and shape of the pieces doesn't affect the size of the pizza. And similarly, the stocks, bonds, warrants, etc., issued don't affect the aggregate value of the firm.

As an economics undergraduate, I also worked on a part-time basis in Cambridge, Massachusetts, for a company that was advising customers about portfolio decisions, writing reports.

Arbitrage proof has since been widely used throughout finance and economics.

If there's 10,000 people looking at the stocks and trying to pick winners, one in 10,000 is going to score, by chance alone, a great coup, and that's all that's going on. It's a game, it's a chance operation, and people think they are doing something purposeful... but they're really not.
