Core Viewpoint - The significant basis management challenges in stock index futures since 2024 are attributed to the historical low basis spreads, particularly influenced by the liquidity crisis in small-cap stocks and the concentrated exercise of out-of-the-money options, indicating strong short-selling pressure from institutional traders [2]. Group 1: Basis Spread Analysis - As of May 23, the annualized basis spreads for the main stock index futures of CSI 300, CSI 500, and CSI 1000 reached 11.08%, 19.08%, and 23.43% respectively [2]. - The substantial basis spread in the CSI 50 and CSI 300 is primarily driven by seasonal dividends, with the annualized hedging costs for the current quarter being -0.27% and 2.86% respectively, suggesting limited impact from upcoming dividends [4][5]. Group 2: Small-Cap Stock Concerns - Despite the influence of dividends, the basis spreads for CSI 500 and CSI 1000 futures remain at historically low levels, indicating a declining risk appetite for small-cap indices among large institutional investors [7]. - The number of neutral strategy products has remained high, with 6,569 products registered since December 31, 2019, but only 2,326 have been liquidated early, suggesting a significant amount of capital is still engaged in stock index futures [7][8]. Group 3: Market Trends and Institutional Behavior - The market has shifted from technology stocks to large-cap blue-chip stocks, driven by macroeconomic events and policy changes, which has increased institutional demand for stable growth assets [10]. - The current high basis costs may erode the alpha portion of neutral strategies, while the potential for profit in arbitrage strategies is lower due to increased volatility and borrowing costs [11][13].

1. Report Industry Investment Ratings - Stock Index: Neutral, with an expectation of a volatile trend [1] - Treasury Bonds: Bearish [2] 2. Core Viewpoints of the Report - **Stock Index**: On May 28, most A - share market indices pulled back. In April, economic data showed a decline compared to March but remained resilient. The social credit demand was weak. Recently, multiple departments announced policies to support the capital market, and internal policy efforts are the main theme for the stock index in 2025. These measures are conducive to helping enterprises repair their balance sheets, promoting the stable development of the real economy, and steadily increasing stock market valuations [1] - **Treasury Bonds**: Treasury bond futures closed with slight declines across various tenors. The central bank conducted reverse repurchase operations, resulting in a net injection of funds. In the short - term, the bond market is unlikely to have a trend - based market. After macro - level disturbances, the bond market will fluctuate according to the capital situation and economic fundamentals. Short - term attention should be paid to the May PMI data and whether the central bank restarts treasury bond trading operations [2] 3.
