Making Money on a Good Idea Missed Opportunities are not always a Bad Thing

Focusing on Buyers and Competitors

by
Say you’re interested in copper. You may start with the mining companies, then move to refiners, then intermediate processors, then metal-bender manufacturers and on up the line. If one area of the business looks lousy, you may want to look at the companies that buy from those people. You may look at the competitors or the alternatives to copper. Thirty-five companies down the road, you’re likely to be in a completely different business and industry and you’ll come across something that looks interesting.
