上证指数创十年新高！机构：当下或是牛市主升浪前期｜快讯

Market Performance - A-shares indices opened high and rose, with the Shanghai Composite Index breaking the 2021 high of 3731 points, reaching a ten-year high since late August 2015, closing at 3740.5 points, up 1.18% [2] - The Shenzhen Component Index increased by 2.25% to 11896.38 points, while the ChiNext Index rose by 3.63% to 2626.29 points [2] - All 31 first-level industry sectors in the market saw collective gains, with telecommunications, comprehensive, and computer sectors leading the rise, while oil, real estate, and banking sectors lagged [2] Bull Market Analysis - Current market conditions may indicate the early stage of a bull market's main upward wave, supported by three key reasons [4] - Firstly, the turnover rate (total transaction amount/total market value) typically reaches a peak during the main upward wave of a bull market. Although trading volume has increased since April, the turnover rate remains significantly lower than the peak observed in early October 2024 [5] - Secondly, there is often a significant change in market style between the early and late stages of a bull market. Since April 2025, small-cap stocks have been dominant, suggesting that if the current phase is indeed the early stage of a bull market, a shift towards large-cap stocks may occur in the later stage [5] - Thirdly, during the main upward wave of a bull market, equity financing typically surges to historical highs. Previous bull markets from 2005-2007 and 2013-2015 saw rapid increases in equity financing during their main upward phases, while current levels remain low [5]
