For example, an investor decides to buy 100 shares of XYZ stock at $33. Before purchasing the shares, he decides that he will sell if the price drops to $30 a share. This way, he knows in advance that his maximum loss, or his risk, will be limited to $300, or a 9% loss. The investor would also choose an exit point for an increase in the stock's price, say, $40. Deciding in advance can help save an investor from holding on too long in either direction. On the other hand, many investors consider it a bad practice to sell if a company's fundamental situation hasn't weakened.
