The list above highlights the biggest percentage movers across market-cap segments for the session. Some entries include brief notes on analyst actions or reported developments tied to the price moves, as indicated in the relevant items.

Context - Movements ranged from single-digit percentage changes among some mega-caps to steep declines and surges among mid- and small-cap names, where volatility tends to be greater. Several companies had explicit catalysts noted alongside their moves, including analyst downgrades, initiations and reports about financing or potential investments.


How to read the list - Each stock is grouped by market-cap category with the percentage change indicated. Items that include a short note reflect context provided alongside the price change in the session's reporting.

Risks

  • Volatility among mid- and small-cap stocks can produce sharp price swings without broad-market catalysts - this affects investors exposed to smaller capitalization names.
  • Analyst downgrades or initiations and reports about financing can materially influence individual stocks' prices, introducing company-specific risk to sectors such as retail and data centers.
  • Significant one-day moves do not necessarily reflect longer-term fundamentals and can add uncertainty for portfolios concentrated in the most heavily moved names.
