Rejecting a stock because the price has doubled, tripled, or even quadrupled in the recent past can be a big mistake. Whether a million investors made or lost money on Chrysler last month has no bearing on what will happen next month. I try to treat each potential investments as if it had no history - the "be here now" approach. Whatever occurred earlier is irrelevant. The important thing is whether the stock is cheap or expensive today at $21-$22, based on its earning potential of $5 to $7 a share. -
