Core Viewpoint - The A-share market has entered a new bull market, marked by the Shanghai Composite Index breaking the 4000-point threshold for the first time in ten years, indicating strong confidence in China's economic future and capital market reforms [3][4]. Market Performance - The Shanghai Composite Index has risen significantly from around 2800 points in September 2024 to over 4000 points in October 2025, reflecting a substantial market recovery [3]. - The total market capitalization of A-shares increased from approximately 68 trillion yuan to 106.6 trillion yuan within a year, representing a growth of 38.6 trillion yuan [3]. - Daily trading volume has surged, with average daily trading exceeding 2 trillion yuan for 40 consecutive trading days, peaking at 3.48 trillion yuan [4]. Market Drivers - The current bull market is driven by "hard technology" rather than the "leverage bull" seen in 2015, leading to more rational valuations and significant structural differentiation [6]. - The technology and new energy sectors have been the primary contributors to market gains, with leading stocks like CATL, BYD, and Cambricon reaching new historical highs [3]. Future Outlook - Analysts suggest that the market may experience short-term fluctuations after breaking the 4000-point mark, as some investors may take profits [9]. - The sustainability of the bull market will depend on whether the "hard technology" sector can translate into continuous profit growth [9]. - Historical data indicates that after a bull market adjustment, sectors with upward trends, such as technology and cyclical industries, are likely to outperform [9].
