New York, Jan 13, 2026, 14:12 EST — Regular session
- Shares of Regencell Bioscience dropped roughly 21% in afternoon trading, significantly lagging the wider market.
- The move deepens a turbulent run for the thinly traded microcap, with sharp swings hitting fast and hard.
- Traders brace for renewed volatility as Wednesday brings U.S. producer-price data.
Shares of Regencell Bioscience Holdings Limited dropped over 20% on Tuesday, continuing a volatile streak that has kept the Nasdaq-listed microcap in the spotlight on momentum trackers.
The decline is significant because the stock has proven it can swing sharply with little notice, a pattern that can catch late buyers off guard and trigger rapid sell-offs when liquidity dries up.
The spotlight returns to what usually moves this stock daily: price action and positioning, rather than a steady stream of news. Investors are asking less “what changed” and more “how far can it swing.”
Regencell plunged 20.6% to $35.01 in afternoon trading. It kicked off the session at $44.37 and hit a high of $45.18 before falling sharply to that intraday low. Roughly 600,000 shares changed hands.
The broader market drifted lower, providing no support for speculative stocks. The SPDR S&P 500 ETF fell roughly 0.3%, the Invesco QQQ Trust dropped about 0.4%, and the SPDR S&P Biotech ETF edged down around 0.6%.
Regencell ended Monday at $44.11, slipping 3.7% after bouncing between $43.27 and $50.22 throughout the session, according to daily trading data. (Yahoo Finance)
Last week, the stock triggered a Nasdaq “volatility trading pause” — a short suspension activated by the limit-up/limit-down rule when a share price jumps or drops abruptly.
In its latest annual report, the company flagged “extreme price and volume fluctuations” in its stock and disclosed it is under regulatory scrutiny linked to the recent market swings. The filing also raised “substantial doubt” about its ability to stay afloat, reporting net losses of $3.58 million for the year ending June 30, 2025. (SEC)
Sharp declines in small, volatile stocks can reverse just as fast. Thin order books, forced selling, and short-covering all fuel these swings. Tuesday’s trading range highlights how quickly bids vanish once sellers step up.
Traders are zeroing in on one thing now: if the stock can hold steady into the close and how it performs Wednesday morning. The U.S. producer price index drops at 8:30 a.m. Eastern. (Bls)
