以史为鉴看本轮风格切换的时间和幅度

Group 1 - The A-share market is currently experiencing an adjustment phase, with a shift from growth to value style, influenced by various short-term disturbances, differing from previous cycles [1][5][7] - A historical review from 2009 shows seven significant phases of style switching in the A-share market, indicating that such transitions are closely related to changes in fundamentals and economic cycles [5][6][7] - The current style switch is primarily driven by short-term factors such as external tariff concerns and profit-taking in the technology sector, rather than fundamental changes in the growth-value dynamic [7][8] Group 2 - The report highlights that the current value style dominance is characterized by two scenarios: upward market adjustments during economic improvements or downward adjustments due to rapid economic declines [6][7] - Historical data indicates that significant style switches often coincide with economic turning points or major policy adjustments, with the probability of switching increasing when the relative difference in ROE between value and growth indices widens [6][7][15] - The report anticipates that the ongoing trade tensions may lead to increased volatility, but the long-term "slow bull" trend remains intact, with specific investment directions suggested in both growth and value sectors [8][15]
