Short float percentage is the rawest measure of squeeze potential: it's the percent of the public float that's currently sold short. A stock with 35% short float has twice as much latent squeeze fuel as one with 17%, all else being equal. But raw short interest doesn't tell you when the squeeze will fire — that's what our composite readiness score on the main squeeze scan tries to capture.
Use this list when you want to find the most heavily shorted names regardless of timing, and use the readiness-ranked list when you want trade setups that are firing now.

Short Float % is the percent of a company's free-tradeable float that's currently sold short. Higher short float means more shares that must eventually be bought back — more potential squeeze fuel. Above 20% is elevated; above 30% is unusually high. The short interest is reported by FINRA and updated bi-monthly.

Days to Cover (DTC) divides the total short interest by the average daily trading volume — an estimate of how many normal trading days shorts would need to exit their positions. DTC above 3 means shorts can't quietly cover on average volume; DTC above 7 means a forced unwind has to push price meaningfully higher to find liquidity.

TTM Squeeze identifies low-volatility periods by detecting when Bollinger Bands contract inside Keltner Channels. The squeeze itself doesn't predict direction — only that volatility expansion is coming — but the accompanying momentum histogram indicates the likely direction of the eventual release. Combine a positive squeeze with positive momentum for high-conviction bullish setups.
