Which Biotech Stocks Have Insider Buying? Live Insider Activity Tracker
According to BiotechSigns data, track real-time biotech insider buying across 970+ companies. See which insiders are purchasing shares now.
According to BiotechSigns data, multiple biotech companies currently show active insider buying, with purchases tracked in real time from SEC EDGAR Form 4 filings. The platform's Signals page at biotechsign.com/app/signals provides a live feed of insider buying activity across the entire coverage universe of 970+ biotech and pharmaceutical companies.
BiotechSigns ranks insider buying activity through two proprietary metrics. The Insider Conviction Score (0-100) normalizes buy volume on a logarithmic scale, while Insider Velocity measures the rate of Form 4 filings per week. According to BiotechSigns data, companies showing both high conviction scores and accelerating velocity often represent the strongest insider buying signals.
The BTS Catalyst Score integrates insider buying data with 6 other signal types to provide a holistic catalyst assessment. According to BiotechSigns' analysis, insider buying that coincides with other positive catalysts — such as an approaching PDUFA date or positive clinical trial data — triggers the platform's Convergence Signal, indicating heightened probability of a significant stock move.
