Tesla Motors (Nasdaq: TSLA) stock attracts short sellers

When a trader is short a stock, he profits when the stock price goes down, and suffer losses when the stock price goes up. The total number of short shares in a stock is called the "short interest".
Stocks with high short interest are often very volatile and are well known for making explosive upside moves, known as a short squeeze. Stock traders will often flock to such stocks for no reason other than the fact that they have a high short interest, and the price can potentially move up very quickly as traders with open short positions move to cover.
In the case of every high, short-interest stock like Tesla, high short interest can mean one of two things. The shorts are right about the fundamental outlook; so the stock is being looked unfavorably and will go down. Or the short sellers are wrong, and any upside news will literally squeeze them into buying back their shares, thus exacerbating the move to the upside. This is an indicator of upside potential in a stock and the higher this number, the more powerful the upside potential a stock has if a short covering should be triggered.
