Group 1 - The classic all-weather strategy faces localization challenges in China, including unstable mapping between macro cycles and assets, the debate over inflation and growth parity, and limitations in the four-quadrant framework [4][8][16] - The core of the all-weather strategy is risk factor hedging, which includes hedging against growth risk with bonds and identifying key risk factors that have historically led to simultaneous declines in stocks and bonds [4][17][23] - Historical instances of simultaneous declines in stocks and bonds have been linked to three main risk factors: high inflation, liquidity tightening, and currency depreciation [23][26][29] Group 2 - A dynamic all-weather strategy based on risk factors can be constructed by either combining subjective views with quantitative models or by implementing a purely dynamic approach without subjective views [38][39] - The dynamic all-weather strategy emphasizes risk timing rather than return timing, focusing on the importance of risk factors in determining asset allocation [4][48] - The performance of the dynamic all-weather strategy has shown to be superior to traditional all-weather strategies, with annualized returns of 6.0% compared to 5.3% for the traditional approach [53]
