What makes stocks valuable in the long run isn't the market. It's the profitability of the shares in the companies you own. As corporate profits increase, corporations become more valuable and sooner or later, their shares will sell for a higher price.

When stocks are attractive, you buy them. Sure, they can go lower. I've bought stocks at $12 that went to $2, but then they later went to $30. You just don't know when you can find the bottom.

Stocks are a safe bet, but only if you stay invested long enough to ride out the corrections.

There seems to be an unwritten rule on Wall Street: If you don't understand it, then put your life savings into it. Shun the enterprise around the corner, which can at least be observed, and seek out the one that manufactures an incomprehensible product.

Long shots almost always miss the mark.

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.

It would be wonderful if we could avoid the setbacks with timely exits, but nobody has figured out how to predict them.
