4) Limited gains. A $20 stock can theoretically go to $1,000 or higher on the long side. A $20 stock can only make you $20 on the short side and that’s only if the company completely goes out of business! Realistically, the company’s stock will stabilize in the single digits even if the common paper is worthless.
5) In 1999, after CMGI’s stock rose from $1 to $120, a very sharp money manager adamantly convinced me that the stock was going back to $1. Once again, he was dead right with his prediction except for one thing: the stock tripled to $360 before it collapsed back to $1!!! This proves the old stock market adage that: “Just when you think a stock can’t go any higher it usually does, and just when you think it can’t go any lower it usually does.”
