Core Viewpoint - The A-share market is experiencing a cooling trend in leveraged funds, with the margin balance in the Shanghai and Shenzhen markets falling below 2.7 trillion yuan, reflecting a shift in investor sentiment from "exuberance" to "rationality" due to multiple factors including high valuation adjustments, regulatory policy guidance, and pre-holiday risk aversion [1][4]. Group 1: Margin Balance Data - As of February 5, the margin balance in the Shanghai and Shenzhen markets was 26,808.60 billion yuan, a decrease of 120.12 billion yuan from the previous trading day, accounting for 2.62% of the A-share circulating market value [2][4]. - The margin balance has declined for six consecutive trading days since January 29, with a total reduction of 617.83 billion yuan [4]. Group 2: Factors Driving the Cooling of Leverage - The recent cooling of leveraged funds is primarily influenced by regulatory policies aimed at stabilizing expectations and heightened risk aversion ahead of the Spring Festival [4][5]. - A key regulatory change on January 14 raised the financing margin ratio from 80% to 100%, increasing the cost of opening positions and suppressing new financing demand, particularly affecting small investors' willingness to engage in high-volatility tech stocks [4][5]. Group 3: Market Sentiment and Fund Flow - The market is currently in a "trading vacuum" period before the holiday, with overall sentiment shifting from "exuberance" to "rationality," as evidenced by a decline in both the margin balance as a percentage of circulating market value and average daily trading volume [5]. - There is a noticeable shift in fund flow, with significant withdrawals from the technology sector and a rotation towards defensive assets such as coal and power, indicating a trend of "selling tech and buying coal" [7]. Group 4: ETF Market and Future Outlook - The ETF margin balance has also decreased, with a total of 1,216.06 billion yuan as of February 5, reflecting a reduction in leveraged exposure to high-volatility assets [8]. - Looking ahead, the activity level of leveraged funds will depend on three key signals: the return of northbound capital and ETF financing post-holiday, clarity in policy expectations, and the liquidity conditions in the interbank market [9].
