How to Make Money Selling Stock Short

It takes real knowledge and market know-how as well as lots of courage to sell, and particularly to sell short, because you will make many mistakes. However, I don’t see how anyone can really do well in the market and protect assets if they don’t learn how, when, and why stocks should be sold. If an investor doesn’t know how to recognize when a stock has topped and should be sold, how can she be sure that the very stocks she is buying aren’t actually giving off indications that they should be sold? Buying without the ability to sell is like a football team that is all offense with no defense. To win, you must understand and execute both.
