The stock market really isn't a gamble, as long as you pick good companies that you think will do well, and not just because of the stock price.

My method for picking stocks has never changed. When businesses go from crappy to semicrappy, there's money to be made.

The worst thing you can do is invest in companies you know nothing about. Unfortunately, buying stocks on ignorance is still a popular American pastime.

Charts are great for predicting the past.

There is always something to worry about. Avoid weekend thinking and ignoring the latest dire predictions of the newscasters. Sell a stock because the company's fundamentals deteriorate, not because the sky is falling.

You have to let the big ones make up for your mistakes.

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