Short Selling And Short Interest Ratios Shocking Secret
Sunday, March 14th, 2010Short selling is a way to make money when a security price starts falling. When you expect a stock to fall in price, you borrow it from your broker and sell it. After sometimes buy it back in order to return it to your broker. The difference between the selling price and the buying price in this case is your capital gain.
Now for short selling to work, the stock price should go down otherwize, you will make a hefty loss in case the stock price starts to go up. Since, you are trading with a borrowed stock, you have to return that stock to your broker. In case the stock price goes up, you will have to buy it back at a much higher price with a loss. Now, when you go short and the market suddenly turns against you in the sense that it goes in the wrong direction, you are in trouble. You want to buy back the stock but the price is continously going up. The harder it becomes to buy back the required number of shares, the more desperate you will become and the higher the prices can go before you are able to buy back the required number of shares and return them to your broker. So in a way, short selling is tricky and must only be practiced by the experienced traders.
In case of futures or options, you don’t need to borrow the security; you simply agree to sell the contract when you go short. Why do investors take a short position? The most obvious reason is that they are expecting the price to go down further. Short selling is also used for hedging purposes.
In the case of stocks, you need to monitor the rate of short selling in order to gauge investor expectation as well as the future market direction. Now, NYSE and NASDAQ report the short interest in stocks listed with them. Now this data is released on monthly basis as the brokerage firms may need a while to report how many shares have been shorted and then report that data to the exchange.
Now this number is known as the Short Interest Ratio. Short Interest Ratio is a very important number for short sellers as it can give important clues about the investor expectation to the short sellers.
So what is the Short Interest Ratio? Short Interest Ratio is the number of shares of a particular stock that has been shorted in the market. Plus the average daily volume for that stock in the same month and also the number of days of trading at the average volume that it would require the market to cover the short positions in that stock. It also reports the percentage change in the short positions from the previous month.
A high short interest ratio should make you nervous if you have taken a short position in that stock as most of the investors who are short will soon become desperate to dump that stock in the market and cover their short positions. The problem with Short Interest Ratio is that it is not calculated frequently. It is calculated on monthly basis. So, the trader cannot use it to gauge the short positions in the market on a daily or weekly basis. However, it can give you the general trend in the market.
