High Short Interest: Good or Bad for Traders?

Now that you know the definition of short interest, when should you get excited or worried about it? Well, this depends on several factors because high short interest can be either good or bad for traders. Market conditions and trading strategies play a role.

You’ll see from the below that understanding what does short interest float mean is important for determining if it’s a good or bad situation.

When is high short interest good?

If you’re on a bullish stock, high short interest can be good for you. That’s because,

when a stock has high short interest, it means many investors are betting against the stock.

So, if the stock’s price starts to rise, these short sellers may need to buy shares to cover their positions and limit their losses. This creates a “short squeeze” that can drive the stock’s price even higher.

This can be beneficial for traders who hold long positions in the stock, as they can profit from the rising price.

When is high short interest bad?

On the other hand, if you’re bearish on stock, high short interest can be bad for you. Consider what would happen if, based on the definition of what is short interest ratio, a stock has high short interest and negative news comes out.

It’d cause a drop in the stock’s price and short sellers may buy back shares to cover their positions. This limits their losses, but it also puts downward pressure on the stock’s price.

An example of this is the short interest ratio GME (GameStop) situation. Due to speculation and influence from social media platforms such as Reddit, GME had a bad high short interest experience that made headlines.

This, therefore, can be terrible for traders who hold short positions in the stock. They’re likely to suffer losses if the price rises instead of falling.

Relationship Between Short Interest and Stock Float

Knowing what is a high short interest ratio aside, we need to know how it’s related to stock float. These two are connected in that short interest is typically expressed as a percentage of a stock’s float.

To further break it down, the stock float refers to the total number of shares of a company’s stock that are available for trading on the open market. Short interest, therefore, is calculated as the total number of shares that have been sold short and not yet covered, divided by the stock’s float.

To help answer the question of “what is short interest percentage?”, here’s an example. If a stock has a float of 20 million shares and there are 2 million shares sold short and not yet covered, the short interest would be 10% (2 million divided by 20 million).

Low Short Interest Stocks

When you have low short interest stocks, it means you have stocks that have a small number of shares sold short by investors. A low short interest typically means that there is a low level of pessimism about the stock’s future performance, as short sellers are betting against the stock’s price.
