It won't matter to Shorts. Shorts are no more than complusive, addicted gamblers. Even frequent shorts make irrational and risky decisions largely based on their expectations of luck. Of course, if they do win, the heightened confidence probably also increases the likelihood that the short will return to the table. If he loses, the resultant negative mood may make him more likely to seek shorting as a way to escape his mood. Thus, shorting is motivated by both wins and losses, and it is easy to see why it is so hard for the compulsive, addicted short to stop gambling.
