I can't recall ever once having seen the name of a market timer on Forbes' annual list of the richest people in the world. If it were truly possible to predict corrections, you'd think somebody would have made billions by doing it.

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.

There's no use diversifying into unknown companies just for the sake of diversity. A foolish diversity is the hobgoblin of small investors. That said, it isn't safe to own just one stock, because in spite of your best efforts, the one you choose might be the victim of unforeseen circumstances. In small portfolios, I'd be comfortable owning between three and ten stocks.

Everyone has the brainpower to make money in stocks. Not everyone has the stomach. If you are susceptible to selling everything in a panic, you ought to avoid stocks and mutual funds altogether.

I've found that when the market's going down and you buy funds wisely, at some point in the future you will be happy. You won't get there by reading 'Now is the time to buy.'

There's lots of stocks out there and all you need is a few of 'em. That's been my philosophy.

Often, there is no correlation between the success of a company's operations and the success of its stock over a few months or even a few years. In the long term, there is a 100 percent correlation between the success of the company and the success of its stock. This disparity is the key to making money; it pays to be patient, and to own successful companies.
