Number of Shares Shorted is the total amount of shares that are currently sold short by investors. When a stock is sold short, the short seller assumes the responsibility of repurchasing the stock at a lower price. The speculator will make money if the stock goes down in price or will experience a loss if the stock price goes up. If a large number of investors decide to short sell an equity instrument within a small period of time, their combined action can significantly affect the price of the stock.
