Risks

  • Sector concentration risk - Gains were driven by a small set of sectors (Automobiles & Parts, Mobile Telecommunications and Software & Computer Services), which could expose the market to sector-specific volatility.
  • Commodity and currency sensitivity - Moves in crude oil, gold and currency pairs could influence earnings and valuations for companies sensitive to commodity prices and FX.
  • Individual stock volatility - Significant single-stock moves, such as Airtel Africa reaching an all-time high, may increase idiosyncratic risk for portfolios with concentrated positions in those names.
