  • Clinical trial disclosures and phase results can produce sharp negative reactions - Shattuck Labs and Fluidigm both fell after reporting clinical and corporate-transaction updates.
  • Heavy reliance on company-specific news increases market volatility in impacted sectors, notably semiconductors, AI hardware, and biotech; such volatility can widen intraday swings.
