The fast growers I keep as long as the earnings are growing and the expansion is continuing, and no impediments have come up. Every few months I check the story just as if I were hearing it for the first time. If between two fast growers I find that the price of one has increased 50 percent and the story begins to sound dubious, I’ll rotate out of that one and add to my position in the second fast grower whose price has declined or stayed the same, and where the story is sounding better.
