Risks

  • High intraday volatility, reflected in large percentage moves, increases short-term trading risk for both buyers and sellers - impacts traders and market makers.
  • Earnings misses and revenue shortfalls noted for some companies (for example Cavco Industries and TFS Financial) create uncertainty for investors in the mid-cap and homebuilding sectors.
  • Sharp declines in semiconductor equipment and related technology stocks (for example KLA-Tencor and Lam Research) suggest sector-specific pressure that could affect supply-chain and capital expenditure expectations in the chip industry.
