Another is, if you take money out of your left pocket and put it in your right pocket, you're no richer.
To beat the market you'll have to invest serious bucks to dig up information no one else has yet.
You only need to make one big score in finance to be a hero forever.
What counts is what you do with your money, not where it came from.
My main interest, however, was in economics, not law.
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.
Arbitrage proof has since been widely used throughout finance and economics.
Most people might just as well buy a share of the whole market, which pools all the information, than delude themselves into thinking they know something the market doesn't.

Junk bonds prove there's nothing magical in a Aaa bond rating.
