Short squeeze
A short squeeze is when a rising stock forces short sellers to buy shares back to limit their losses, and that buying pushes the price up further.
A short seller has borrowed shares and sold them, so a rising price is a growing loss with no natural ceiling. To stop the bleeding they have to buy the shares back — and buying is exactly what pushes the price higher, which puts the next short seller under the same pressure. When enough of them are forced to buy at once, the feedback loop can move a stock far more than the underlying news would justify. That loop is the squeeze.
Three separate things have to be true before one is even possible, and they come from different measurements. The short position has to be crowded — a large share of the company sold short, so there is a real crowd to squeeze. The exit has to be narrow — days to cover, which compares the short position to the stock’s normal trading volume, because a crowded short in a heavily traded stock simply unwinds without drama. And the price has to be moving against the shorts, since a losing position is what forces the buying. Any one of the three on its own says very little.
A squeeze is not a company doing well, and a heavily shorted stock is not a bargain. The move comes from position mechanics rather than from earnings or products, it can reverse as fast as it came, and most heavily shorted stocks never squeeze at all. Short interest can also be a hedge or part of a merger-arbitrage trade rather than a bet against the business, in which case there is no conviction to break. stocks-llm reports the ingredients from official FINRA disclosures and its own price history, each with its own date, and calls the resulting list candidates — it does not predict squeezes and never presents one as a reason to buy.
