Risks

  • Widespread intraday percentage swings across mega-, large-, mid- and small-cap categories indicate elevated short-term volatility for market participants.
  • Concentrated, large declines in multiple technology and semiconductor names could contribute to uncertainty in the technology sector's intra-day performance.
  • Sharp moves in smaller-cap listings underline liquidity and price-movement risks within the small-cap segment during the session.
