概率驱动的行业轮动决策框架：基于胜率与盈亏比的行业博弈策略

Group 1 - The report emphasizes a probability-driven approach to industry rotation, treating industry indices as repeatable gaming objects rather than one-time market judgments, focusing on win rates and profit-loss structures to assess long-term gaming value [3][12][14] - A counter-cyclical selection mechanism is introduced, which utilizes historical performance memory for weak industries, allowing for the retention of industries with reversal potential during rotation and style shifts [4][35] - The application of the Kelly formula optimizes weight distribution among selected industries, enhancing capital efficiency and long-term return quality while maintaining the selection results [5][42] Group 2 - The report outlines a basic win rate scheme based on a 24-month window, indicating that this mid-term win rate is more stable and sustainable for future returns compared to shorter periods [17][18] - The performance results show an annualized excess return of 9.6% since 2015, with a smoother return path, indicating a shift from phase-based betting to pricing long-term success capabilities [39][46] - The strategy demonstrates a systematic preference for consumer-related industries, particularly in home appliances, food and beverage, and pharmaceuticals, driven by win rates and profit-loss structures [57] Group 3 - The report highlights the importance of using comprehensive profit-loss indicators to enhance signal effectiveness, allowing for a more stable assessment of industry performance [39][46] - The strategy's weight distribution is designed to favor high win rate and high profit-loss ratio industries, improving both return stability and risk-adjusted returns [46][47] - The analysis indicates a low turnover rate, suggesting that the strategy does not chase market hotspots but rather relies on rational selection based on win rates and profit-loss metrics [57] Group 4 - The report identifies a high concentration in industry selection, with notable frequencies in sectors such as non-ferrous metals, food and beverage, and home appliances [55] - Recent holdings reflect a focus on industries with potential for recovery, indicating a strategic approach to capitalizing on past successful sectors [56] - The findings suggest that the strategy is not overly dependent on specific industries, as it maintains a diversified approach while still achieving significant returns [58]
