Kopp Glass is an example of a perfect oddball stock. It's a very small company that operates in a niche, yet earns extremely high returns on capital. The problem is they can't scale their market. So while they have a nice moat, and earn great returns they don't have much growth potential. The company has paid out most of their earnings as dividends, and shareholders seem content to earn a close to 10% dividend as well as some appreciation.
