We recently compiled a list of the 12 Healthcare Stocks with Insider Buying in 2025. Regencell Bioscience Holdings Limited is one of them.

Regencell Bioscience Holdings Limited (NASDAQ:RGC) tops our list for being one of the stocks with insider buying. It is a Hong Kong-based biopharmaceutical company developing Traditional Chinese Medicine (TCM) treatments for neurocognitive disorders such as ADHD and autism spectrum disorder (ASD).

A key milestone came on September 21, 2025, when RGC was added to the S&P Global BMI Index, boosting its visibility among institutional and passive investors. This inclusion may enhance liquidity and help stabilize the stock, which has been highly volatile. Despite this progress, the business continues to face fundamental challenges, including zero revenue, ongoing losses, and uncertain regulatory pathways for its treatments.

On the clinical front, Regencell Bioscience Holdings Limited (NASDAQ:RGC) reported positive results from its second efficacy trial using standardized TCM formulae for ADHD and ASD, showing a mean symptom improvement of 37% with no adverse side effects. While encouraging, no FDA-approved products have been announced yet, and the treatments remain investigational.
