All the math you need in the stock market you get in the fourth grade.

Just because you buy a stock and it goes up does not mean you are right. Just because you buy a stock and it goes down does not mean you are wrong.

The person that turns over the most rocks wins the game. And that's always been my philosophy.

If you hope to have more money tomorrow than you have today, you've got to put a chunk of your assets into stocks. Sooner or later, a portfolio of stocks or stock mutual funds will turn out to be a lot more valuable than a portfolio of bonds or CDs or money-market funds.

All the time and effort people devote to picking the right fund, the hot hand, the great manager have, in most cases, led to no advantage.

That's not to say there's no such thing as an overvalued market, but there's no point worrying about it.

An important key to investing is to remember that stocks are not lottery tickets.
