This strategy achieved an annualized return of 8.74% since 2017, with a maximum drawdown of 23.5%, and a 2025 return of 7.5%[13][16] - The report also constructs two concept-based portfolios: a "TOP" portfolio selecting the top 10 stocks with the highest total heat within the top 5 concepts with the largest heat change, and a "BOTTOM" portfolio selecting the bottom 10 stocks with the lowest total heat within the same concepts. The "BOTTOM" portfolio historically achieved an annualized return of 15.71%, with a maximum drawdown of 28.89%, and a 2025 return of 17%[30][32]
