Counts shares borrowed and sold by bearish investors, exposing the aggregate size of bets that the stock price will decline.
Shares short is the total number of shares that investors have borrowed and sold, hoping to buy back cheaper later. A high short interest can signal pessimism or set up potential short squeezes.
Shares short (or short interest) represents the total number of shares that have been sold short and not yet covered or closed out. Short selling involves borrowing shares and selling them, with the obligation to eventually buy them back. High short interest indicates that many investors are betting the stock price will decline.
The mechanics of short selling:
- Investor borrows shares from a broker (who sources them from other clients' holdings)
- Borrowed shares are sold immediately at current market price
- Eventually, the investor must buy shares to return to the lender ("covering" the short)
- Profit occurs if the repurchase price is lower than the sale price; loss if higher
Short interest data is typically reported twice monthly by exchanges with a delay of about 10 days. This lag means the figures represent historical snapshots rather than current positions.
Key interpretations of short interest:
- Bearish sentiment: High short interest suggests widespread expectation of price decline
- Contrarian indicator: Extremely high shorts can signal excessive pessimism, potentially setting up a rally
- Short squeeze risk: If price rises, short sellers may rush to cover, accelerating the upward move
- Hedge activity: Some shorts are hedges rather than directional bets, complicating interpretation
For example, a company with 10 million shares short out of 100 million outstanding has 10% short interest. If only 50 million shares are in the float, short interest relative to float is 20%—a more meaningful figure for assessing squeeze potential.
Short sellers face unique risks:
- Unlimited loss potential: A stock can theoretically rise indefinitely, magnifying losses
- Borrowing costs: Hard-to-borrow stocks carry high lending fees
- Forced covering: Lenders can recall shares, forcing shorts to close at inopportune times
- Dividend payments: Short sellers must pay any dividends to the share lender
Increasing short interest over time may warrant investigation into why sophisticated investors are betting against the stock. However, high short interest alone isn't a sell signal—sometimes the shorts are wrong.
How it relates
Shares Short÷Avg 30-Day VolumeAverage 30-day volume is the average number of shares traded per day over the last 30 trading days. It gives a more stable view of typical trading activity.=Short RatioShort ratio (days to cover) tells you how many days of average trading it would take for all short sellers to buy back their borrowed shares. Higher values mean shorts could take longer to close their positions.
Shares Short÷Shares OutstandingShares outstanding is the total number of shares that exist for this company. It's used to calculate things like market value and earnings per share.=Short % of Shares OutstandingShort % of shares outstanding shows what fraction of all shares have been sold short. A high percentage can mean strong bearish sentiment or the potential for a short squeeze.
