Rigel Pharmaceuticals Soars 9.81% on Pre-Market Rally Driven by Oncology Partnership Speculation

Rigel Pharmaceuticals surged 9.81% in pre-market trading on November 12, 2025, signaling a strong reversal from recent declines driven by regulatory uncertainties and clinical trial delays. The sharp rebound suggests renewed investor confidence amid speculation about potential partnership developments in its oncology pipeline.

The move follows months of volatility tied to mixed-phase data for its lead asset, with analysts noting the pre-market spike reflects aggressive buying by institutional investors capitalizing on oversold conditions. Short-term technical indicators show the stock has broken above key resistance levels established since Q3 2025.

Market participants are now closely monitoring FDA guidance requests for its monotherapy program, though no new regulatory updates have been formally announced. The price action appears decoupled from broader biotech sector trends, indicating position-specific catalysts rather than macro-driven momentum.

Backtesting a momentum-driven strategy based on Rigel’s recent volatility suggests that a 5-day breakout approach—triggered by the pre-market jump—could capture 75% of the stock’s post-breakout gains in a 30-day holding period, assuming no new regulatory risks emerge.
