See how many shares are sold short, how crowded the trade looks, and how daily short-sale activity compares with its own baseline, with the date behind every number.
Every figure carries the date it refers to. Anything that cannot be verified is marked N/A instead of guessed.
Scan up to 30 symbols, then filter by short positioning, daily short-sale activity and volume.

Short interest is the total number of shares of a stock that investors have sold short and not yet bought back. A short seller borrows shares, sells them, and hopes to repurchase them later at a lower price. Until the shares are returned, the position counts toward the stock's short interest.
Firms report these open positions twice a month, and a summary for each stock is published several days later. That makes short interest a snapshot of positioning on a past settlement date, not a live reading. Readers usually compare it with the stock's float (the shares available to trade) to judge how crowded the short side is, and with trading volume to judge how long it could take to unwind.
A rising number of shares sold short can mean more investors expect the price to fall, or that hedgers and arbitrageurs are offsetting other positions. A high number can also set up sharp moves if the price rises and short sellers rush to buy shares back. Short interest does not say which of these is happening, which is why this tracker shows several related measures side by side instead of a single score.
Shares sold short and still open at the latest settlement date. The tracker also shows the change from the previous report after adjusting for any stock split between the two dates, so a split is never mistaken for a surge in positions.
shares short ÷ free float. Shown only when a dated float figure is close enough to the report date to be comparable. Otherwise the tracker says N/A and explains why.
shares short ÷ average daily volume. A rough measure of how many typical trading days short sellers would need to buy back their shares if they were the only buyers.
short-sale volume ÷ covered volume. The share of reported off-exchange volume that was sold short each day, compared with the stock's own baseline over the previous 20 observations.
The two terms sound alike but answer different questions. Mixing them up is the most common way to misread this kind of data.
| Short interest | Short-sale volume | |
|---|---|---|
| What it measures | Open short positions at a settlement date | Short sales executed during a trading day |
| Update cadence | Twice a month | Daily, after the close |
| Delay | Published several days after the settlement date | Available after each trading day |
| Coverage | Reported positions across the market | Reported off-exchange trading only |
| Best for | Judging how crowded the short side is | Spotting changes in daily selling activity |
| Common mistake | Treating an old snapshot as current | Treating short sales as new bearish bets |
Short volume counts sales, not positions. A trader who sells short in the morning and covers in the afternoon adds to short volume but leaves no open position. For that reason the daily ratio is best read as a change against the stock's own baseline, not as a measure of how many shares are held short.
The tracker favors verified, comparable data over a complete-looking dashboard. When an input fails a check, the affected metric is shown as N/A with a note instead of being estimated.
Short interest is one input among many. A few habits keep it in perspective.
There is no single threshold. Many traders treat short interest above roughly 10% of float as elevated and above 20% as heavily shorted, but the better comparison is the stock's own history and its peers. The tracker's squeeze-watch filter uses 10% as one input, together with days to cover, relative volume and a price above its 20-session average. A match is a research prompt, not a prediction.
Days to cover divides the shares sold short by the stock's average daily trading volume. A value of 5 means it would take about five average trading days of volume to buy back every short share. A higher number suggests a position that is harder to unwind quickly, but it is only a rough guide because short sellers do not cover at an even pace.
No. A squeeze needs a catalyst that pushes the price up and forces short sellers to buy shares back. High short interest can make such a move sharper, but many heavily shorted stocks never squeeze. Treat it as a measure of how crowded the short side is, not as a forecast.
It is the share of a day's reported off-exchange trading volume that was sold short. Because market makers and other liquidity providers often sell short as part of ordinary trading, a ratio well above zero is normal. The tracker compares each day's ratio with the stock's own prior 20-observation baseline, which is more informative than the raw level. It measures selling activity, not new bearish positions.
Short positions are reported twice a month for a specific settlement date and published several days later, so the figures always describe a past date. The tracker shows the settlement date of the latest report next to every position metric. Daily short-sale volume updates after each trading day.
A metric is marked not available when its inputs are missing, stale, or could not be verified for comparison, for example when a dated float is too far from the report date or the split history is unavailable. This is deliberate. A missing value is never shown as zero, and it does not mean the stock has no short sellers.
Yes. You can search stocks, run the screener and use the watchlist without creating an account. Your watchlist, alert conditions and alert history are stored in your browser only.
No. Borrow cost and availability are not included. For heavily shorted stocks they can matter, so consider them separately.
No. The tracker is for education and research only. It does not recommend buying or selling any security, and past short-interest patterns do not predict future returns.
Educational use only. StrongBuyAnalytics does not provide personalized investment advice. Short-interest and short-sale figures are reported with a delay, can be revised, and may be incomplete. Verify important figures before you act, and never base a decision on a single indicator.
