What affected the Fund’s performance?

  • Stock selection in communication services and financials, alongside overweight exposure to consumer discretionary, were the strongest positive contributors to the Fund’s relative performance.
  • Stock selection within the strong information technology sector, combined with weak stock selection in health care and industrials, detracted most from relative performance.
