Core Viewpoint - The article highlights the strong performance of micro-cap stocks, particularly in the context of the Shanghai Composite Index's fluctuations around the 4000-point mark, indicating a growing market interest in this segment [2]. Group 1: Performance Comparison - Since 2010, the micro-cap stock index has outperformed major indices like the Shanghai 50, CSI 300, CSI 500, CSI 1000, and National 2000 in most years, except for 2017 and 2020 [2]. - The absolute performance data shows that in 2015, the micro-cap index surged by 229%, while the CSI 300 only increased by 6% [3]. - In 2023, the micro-cap index recorded a 50% increase, significantly outperforming other indices [3]. Group 2: Excess Returns Analysis - The excess returns of the micro-cap index are attributed to PB (Price-to-Book) recovery and the switching between high and low valuations [8]. - The report indicates that the contribution of trading frequency to excess returns is limited, while the profitability of micro-cap stocks does not significantly influence their overall returns [8]. - The strategy behind micro-cap stocks is characterized by a "reverse selection" feature, where stocks that have risen significantly are removed from the index, allowing for a systematic "buy low, sell high" approach [6]. Group 3: Trading Strategy Insights - The micro-cap index employs a mechanism that automatically executes a rebalancing strategy, enhancing its ability to capture structural reversal opportunities during market volatility [6]. - The trading environment for micro-cap stocks is influenced by both short-term trading and momentum strategies, which can amplify volatility during periods of liquidity tightening or systemic risk [8].

Group 1 - The core viewpoint of the report emphasizes that the micro盘股 strategy has gained significant attention in the past two years, driven by a logic of accumulating excess returns through capital games and trading efficiency in a high-volatility environment [1][10][12] - The Wind micro盘股 index outperformed major broad-based indices twice in 2025, first from May to July with a return of +31.81% compared to +17.26% for 中证 2000 and +4.93% for 上证 50, and again in October with a +5.51% return while major indices showed minimal fluctuations [1][11][12] - The report identifies three main reasons for the leading performance of micro盘股: liquidity easing often leads micro盘股 to rebound ahead of indices, the index's "reverse selection" characteristic allows for intrinsic profit-taking and rebalancing, and the strategy focuses more on market self-repair and contrarian reactions compared to traditional cyclical strategies [2][12][13] Group 2 - A historical review shows that micro盘股 has a "double-edged sword" characteristic, providing high elasticity and excess return advantages but also amplifying volatility during liquidity tightening or systemic risk phases [3][20][22] - In bull markets dominated by public and foreign capital, micro盘股 strategies underperformed compared to cyclical investment strategies, while in bear markets, they were impacted by emotional and liquidity shocks [21][22] - The current market environment features diversified funding sources and enhanced stability, with the micro盘股 style expected to continue its upward potential, acting as a "risk appetite thermometer" and "sentiment leading indicator" for the ongoing bull market [4][26][33] Group 3 - The report suggests investment strategies focusing on the strong performance of micro盘股, particularly in the context of liquidity abundance and rising risk appetite, recommending attention to sectors like technology and cyclical rebalancing [34] - Specific sectors highlighted include photovoltaic, chemicals, steel, non-ferrous metals, and electric power, as well as technology growth areas such as AI hardware and military applications [34]
