Post highlights FGMC (soon to trade as BOXABL on Nasdaq) as the most heavily shorted stock at 120% of float with under 1 million tradeable shares despite $3.5B valuation. Key risks include execution risk on deal closure by end of July, extreme volatility from high short interest, and potential for negative price movement if merger fails or shorts cover gradually.

FGMC is identified as the #1 most shorted stock on MarketWatch with 120.82% of float shorted, suggesting a potential short squeeze scenario. The post questions the mechanics of how shorts will cover more shares than available float, implying bullish squeeze potential but carrying significant risks of volatility and potential regulatory action.
