Risks

  • Volatility among small- and mid-cap stocks, as shown by multiple 10% moves, increases sector-specific execution and liquidity risk - particularly relevant to plastics, computer hardware and energy-related names.
  • Commodity price swings - higher oil and lower gold - can affect input costs and margins for manufacturers and energy-linked firms, introducing earnings uncertainty for affected sectors.
  • Significant downside moves to multi-year and all-time lows for certain companies highlight idiosyncratic risk for investors in individual small-cap listings.
