Retail Hype and Options Volatility Drive RGC’s Surge
Regencell Bioscience’s 28.77% intraday rally is fueled by a confluence of speculative retail trading and social media-driven momentum. The stock’s June 2025 38-1 split, coupled with its focus on Traditional Chinese Medicine (TCM) for neurocognitive disorders, has attracted attention from retail investors. Recent news highlights a 9,800% surge in 2025, despite the company posting consistent losses and lacking revenue. Options data underscores the frenzy: the RGC20260116C35 call option has seen a 306.78% price change ratio, with implied volatility at 189.22%. This surge aligns with broader trends of meme stock dynamics, where retail traders amplify price swings through coordinated buying and social media chatter.

RGC’s Volatility: A High-Risk, High-Reward Gamble
Regencell Bioscience’s 28.77% intraday surge underscores the stock’s extreme volatility, driven by speculative retail trading and social media hype. While technicals suggest overbought conditions (RSI 70.37) and a bullish MACD, the stock’s fundamentals remain weak, with a dynamic P/E of -4,803.87. Traders should monitor the $35.68 intraday high as a critical resistance level and watch for a breakdown below $30 to signal a reversal. For now, options like RGC20260116C35 and RGC20260220C30 offer high-leverage plays, but caution is warranted. Watch for $35.68 breakdown or a shift in retail sentiment. Meanwhile, sector leader Johnson & Johnson (JNJ) rose 0.45%, offering a safer alternative for diversified portfolios.
