Short Interest FAQ
Q: What is short interest?
Q: How can short insight be used for trading?
A: There are a few ways that you can use short insights:
- When there is no change in short interest, but the stock price is falling, you know long holders of the stock have lost confidence and are selling. This may be the beginning of a very significant downward trend. Conversely, when there is little or no change in short interest and the stock price rises, there is natural long-buying occurring in the marketplace.
- If there is an increase in shares shorting, this will cause downward price pressure on stocks, whereas short covering will cause upward price pressure on stocks.
- You can calculate net return when you’re considering a trade: For instance, if you expect your short trade to have a 10% return, but you are going to pay an 8% financing cost, you wouldn’t get into the trade because your net return will only be 2%. It is important to calculate your net return for every short transaction you consider.
- Short interest gives you insight into option pricing for covered calls, protective puts and straight option buying and selling. High stock-loan fee stocks have high option premiums, which make some option trades more attractive and some less attractive. The movement in stock-loan rates generally occurs prior to moves in option premiums.
- It’s important to note that the ways in which you can use the data, are the precise ways in which institutions use it as well.
