Buy low and sell high is the rule of investing everyone know. It sounds easier than it is because when you buy low it means that everyone else does not see value in that business. You have to go against the grain and be right. Low companies are those that not proven and have fallen from the top and are on the way down. The opportunities are right in front of you. I would rather a rusty car with a good engine that a new paint job on a broken down jalopy.
