It doesn’t have to be a turnaround in sales that gets your attention. It may be that companies you know about have incredible hidden assets that don’t show up on the balance sheet. If you work in real estate, maybe you know that a department store chain owns four city blocks in downtown Atlanta, carried on the books at pre–Civil War prices. This is a definite hidden asset, and similar opportunities might be found in gold, oil, timberland, and TV stations.
