- The DecompGRU model was used to construct a weekly long-only stock selection portfolio, holding the top 200 stocks with the highest integrated scores based on the model. The portfolio is rebalanced weekly on the first trading day, using factor values updated after the previous Friday's close. Stocks from the CSI All Share Index are selected, excluding stocks with trading halts or price limits, and transaction costs are not considered. The benchmark for comparison is the CSI All Share equal-weighted index[7][9] - The DecompGRU model's stock scores were aggregated to construct an ETF rotation portfolio. The ETF pool is limited to industry and thematic ETFs, retaining only the ETF with the highest 5-day average trading volume if multiple ETFs track the same index. ETFs must meet minimum trading volume criteria (5-day average > 20 million and 20-day average > 10 million). The portfolio holds 2-6 ETFs per period and is rebalanced weekly without a fixed schedule. The benchmark for comparison is the Wind ETF Index[10][12] - A sentiment factor was constructed using user behavior data from Tonghuashun, aggregating stock-level heat metrics (browsing, watchlist, and click counts) normalized by market share on the same day and multiplied by 10,000.

The strategy's annualized return since 2017 is 8.74%, with a maximum drawdown of 23.5%.

Stocks within these concepts were filtered to exclude the bottom 20% by market capitalization. Two portfolios were created: a "TOP" portfolio holding the top 10 stocks by total heat within each concept, and a "BOTTOM" portfolio holding the bottom 10 stocks. The BOTTOM portfolio achieved an annualized return of 15.71% with a maximum drawdown of 28.89%. In 2025, the BOTTOM portfolio returned 41.8%[40][41] - The DecompGRU TOP200 portfolio achieved a cumulative absolute return of 60.48% and an excess return of 34.62% relative to the CSI All Share equal-weighted index since its inception on March 31, 2025.
