The opposite strategy to the one discussed in this article, is to buy high and sell low. However, this way of trading doesn’t apply to every stock. Instead, the general idea here is for you to buy the best stocks, as measured by their performance in the market.
If you purchase strong stocks, you can hold them while they gain value, and sell once their performance starts deteriorating. This technique is based on so-called “relative strength,” i.e., a stock’s strength relative to the market.
