Risks

  • Earnings and guidance-related announcements continue to drive outsized moves in mid- and small-cap stocks, creating elevated short-term volatility for those sectors.

  • Some small-cap issuers reported large percentage moves tied to company-specific credit or operational issues, indicating higher idiosyncratic risk among lower market-cap stocks.
