If you own a portfolio of stocks, you must learn to sell the worst performers first and keep the best a little longer.

It is one of the great paradoxes of the stock market that what seems too high usually goes higher and what seems too low usually goes lower.

I've never met a successful pessimist.

90% of the people in the stock market, professionals and amateurs alike, simply haven't done enough homework.

Forget the adage buy low and sell high.

If you own a portfolio of stocks, you must learn to sell the worst performers first and keep the best a little longer.

So the first thing I learned about how to get superior performance is not to buy stocks that are near their lows, but to buy stocks that are coming out of broad bases and beginning to make new highs.
