  • Concentration risk in model-driven strategies - the approach uses up to 20 high-conviction stocks per strategy with equal weighting, which can lead to outsized exposure to individual company outcomes (impacts investor portfolios and sector allocations).
  • Performance persistence uncertainty - while historical returns since the November 2023 model launch are presented, past recorded performance does not guarantee future results and momentum can reverse (impacts investors in the highlighted stocks and strategies).
