Group 1 - A-shares have outperformed U.S. stocks, with a relative excess return exceeding 15% since the second half of the year, marking the highest level since 2015 [1][3] - The probability of A-shares outperforming U.S. stocks increases when both markets rise together, with A-shares winning approximately 54% of the time in such scenarios [3][5] - Historical analysis shows that A-shares have outperformed U.S. stocks in 10 distinct phases since the early 1990s, with the average duration of these phases being around 10 months [5][6] Group 2 - The main factors influencing A-share performance during winning phases include valuation and earnings contributions, with valuation changes playing a more significant role [6][10] - In winning phases, sectors such as machinery, finance, military, and technology tend to perform better, although specific sector performance can vary by economic conditions [10][12] - A-shares typically outperform during upward phases of the economic cycle, but can also win during U.S. economic downturns if the U.S. market experiences significant corrections [12][17] Group 3 - The current winning phase for A-shares began in June 2025, with the potential for continuation depending on market conditions and policy support [20][21] - Future performance may depend on whether both markets enter a cooling phase, with a greater decline in U.S. stocks, or if A-shares continue to rise independently [21]
