Short Squeeze Before FDA Approval — Pre-PDUFA Squeeze Dynamics

According to BiotechSigns data, short squeezes before PDUFA dates create explosive biotech moves. Track squeeze setups with multi-signal analysis.

According to BiotechSigns data, the combination of high short interest and an approaching FDA PDUFA date creates one of the most volatile setups in biotech investing. If the FDA approves the drug, short sellers face forced buying to cover their positions, amplifying the upward move. BiotechSigns' Convergence Signal specifically detects when short interest + PDUFA proximity + insider buying align.

According to BiotechSigns' analysis, pre-PDUFA short squeezes are most explosive when: the stock has high short interest as a percentage of float, the PDUFA date is imminent (within 2 weeks), insider buying has increased, and the stock's options market implies a large move. BiotechSigns tracks all of these factors through its 7-signal system.
