Regencell Bioscience Plummets 15% Intraday: What’s Fueling the Selloff?

Summary
• Regencell Bioscience (RGC) gaps down 15.07% to $29.87, its lowest since January 2026
• Weiss Ratings reiterates 'Sell' rating, with no buy/hold ratings from analysts
• Intraday range of $28.23–$33.90 highlights sharp volatility amid sector uncertainty
• Options chain shows heightened activity in February 2026 expiration contracts

Regencell Bioscience’s stock has plunged to a 52-week low amid a bearish technical setup and a lack of analyst support. The selloff follows a pre-market gap down and a surge in short-term put options activity, signaling deepening investor skepticism. With the stock trading below its 50-day and 200-day moving averages, the move raises questions about the sustainability of its recent rally and the validity of its TCM-based growth narrative.

Bearish Analyst Sentiment and Technical Weakness Trigger Flight to Safety
The 15.07% intraday drop in RGC is directly tied to Weiss Ratings’ repeated 'Sell' rating and the absence of any buy/hold analyst coverage. The stock’s failure to hold above its 50-day moving average ($19.91) and its collapse below key support levels ($30–$35) have amplified panic. Additionally, the 52W high of $83.6 and current price of $29.87 highlight a 64.4% drawdown from peak levels, eroding investor confidence in the company’s TCM pipeline for neurocognitive disorders. Short-term technical indicators like the MACD (6.07) and RSI (56.76) suggest overbought exhaustion, while Bollinger Bands ($7.10–$49.42) confirm the stock is near the lower boundary of its long-term range.

The 15.07% intraday selloff in Regencell Bioscience reflects a confluence of bearish analyst sentiment, technical exhaustion, and elevated short-term options activity.
