Short Interest % Float

The percentage of a company's publicly tradable shares (float) that are currently held short by investors betting on a price decline.

Short Interest % Float is a sentiment metric that measures the percentage of a company's publicly tradable shares (the float) that are currently held short. It represents the proportion of shares that have been borrowed and sold by investors who are betting that the stock's price will decline, with the intention of buying them back later at a lower price to pocket the difference. To calculate this metric, the total number of shares currently sold short is divided by the company's public float, then multiplied by 100. Because the public float excludes closely held insider shares and locked-up stock, using the float rather than total shares outstanding provides a more accurate picture of the actual liquid supply available to the market. Investors monitor this percentage to gauge the intensity of bearish sentiment. A low percentage (under 5%) generally indicates normal market activity or neutral-to-bullish sentiment. A high percentage (typically above 10% to 15%) signals heavy skepticism and active bets against the company. However, an extremely high short interest can also act as a contrarian indicator, setting the stage for a short squeeze where positive news forces short sellers to buy back shares rapidly to limit losses, driving the stock price up exponentially.

Company A has 50,000,000 shares outstanding, but only 40,000,000 of those shares make up the public float. If market participants have borrowed and sold short 8,000,000 shares, the Short Interest % Float is calculated as (8,000,000 / 40,000,000) 100 = 20%.
