Leading the list is Grace Therapeutics, Inc. Common Stock (GRCE) with 22.9% short float, 7.0 days-to-cover, readiness score of 66, in the “Coiled” phase. Also worth attention: Oragenics Inc. (OGEN).

A short squeeze in a $5B large-cap might mean a 10-20% move; in a $30M nano-cap it can mean 100-300% in days. The mechanics are the same — shorts are forced to buy back shares to cover, pushing the price up, which forces more covering — but the magnitudes scale inversely with float size. Less float to cover into = more violent gap-ups.
What makes a nano-cap squeeze setup work:
Nano-caps are the highest-risk, highest-reward end of the squeeze universe. Position sizing discipline matters more here than anywhere else.

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.
