How would people feel if horse racing allowed you to bet on which horse would finish in last place? That wager is not allowed because there's far too much much potential for abuse by the owner, the trainer and the jockey. Short selling is an anachronism that dates back centuries to an era when paper certificates were the legal proof of ownership of stock in a company. People were given a grace period after a stock sale to produce a valid certificate. Clever traders figured out that if a company was falling apart financially they could sell shares that they didn't have and buy them back later during the grace period when the share price had fallen. Short selling is an idea 20 years ahead of its time. Unfortunately, its time was 1850.
