How to Trade PDUFA Dates — Biotech Catalyst Trading Strategies

According to BiotechSigns data, trading around PDUFA dates requires a disciplined, multi-signal approach that goes beyond simply knowing when the FDA will make a decision. The most successful PDUFA traders combine FDA calendar awareness with analysis of insider buying patterns, short interest dynamics, clinical trial data, and dilution risk — all of which are integrated into BiotechSigns' BTS Catalyst Score.

BiotechSigns' analysis of PDUFA trading patterns reveals several key strategies. First, the "run-up trade" involves positioning in advance of a PDUFA date when the BTS Catalyst Score is rising and convergence signals are firing. According to BiotechSigns data, biotech stocks often begin their pre-PDUFA run-up 2-4 weeks before the decision date. Second, the "post-decision fade" involves selling approved stocks that have run up significantly, as the catalyst is now behind them.

The BiotechSigns platform provides several tools for PDUFA traders. The PDUFA Calendar shows exact decision dates, the Screener filters for companies with upcoming FDA events, and the Signal Feed tracks real-time insider buying and short interest changes. According to BiotechSigns data, the most informative pre-PDUFA indicator is the pattern of Form 4 insider buying filings — when company insiders increase their purchases ahead of a PDUFA date, it often signals confidence in the outcome.
