专访刘俏:中国股市具备慢牛的基础,但散户不一定能赚钱
经济观察报· 2026-03-31 10:57
Core Viewpoint - The perception that higher trading activity indicates a more vibrant market is a misconception; in fact, in the Chinese A-share market, trading volume and pricing efficiency are inversely related, with higher trading volumes leading to lower pricing efficiency due to the dominance of retail investors [1][3]. Market Structure and Pricing Efficiency - Currently, 60% of the trading volume in the A-share market is contributed by individual investors, whose trades often lack informational content, leading to what is termed "noise trading" [3][13]. - To improve pricing efficiency and the informational content of stock prices, it is crucial to change the investor structure towards a more institutionalized model [3][15]. Economic Conditions and Market Outlook - Liu Qiao, a prominent economist, highlighted that some industries are trapped in a cycle of low prices, low profits, and low incomes, which affects overall economic vitality [2][5]. - The Chinese stock market has the foundation for a "slow bull" market, supported by the long-term growth potential of the economy and the continuous improvement in the quality of listed companies [2][12]. - A potential turnaround in the price index is expected by the second half of this year or early next year, which could positively impact the capital market [2][12]. Monetary Policy and Price Recovery - The current monetary policy aims to facilitate a reasonable recovery in prices, which is seen as essential for economic stimulation [5][6]. - Structural interest rate cuts are recommended to lower financing costs for households and small to medium enterprises, which could enhance consumer spending and economic activity [6][7]. Structural Issues in the Economy - The persistent low prices have created a structural cycle that suppresses economic growth, where low product prices lead to low corporate profits and subsequently low labor incomes [5][9]. - Addressing these structural issues requires promoting reasonable price recovery, allowing companies to achieve reasonable profit margins, and enhancing labor income [10][9]. Institutional Investment and Market Dynamics - The dominance of retail investors in the A-share market leads to inefficiencies; thus, accelerating the institutionalization of the market is essential for improving pricing efficiency [15][17]. - The U.S. market successfully reduced the proportion of retail trading from 60%-80% to around 10% over several decades, which is a model for improving the A-share market's efficiency [15][17]. AI and Economic Growth - Current AI applications have limited short-term impact on economic growth, contributing only about 0.06% to total factor productivity growth [18]. - Long-term investment in AI applications is expected to yield more significant economic benefits, although the immediate effects may be overstated [18].
