1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The basis level and volatility of stock index futures show clear style stratification, with solid financial logic support for statistical laws. The volatility of the basis of small - and mid - cap stock index futures (IC, IM) is systematically higher than that of large - cap varieties (IF, IH). The basis presents a leptokurtic and thin - tailed feature, and there are differences in the distribution form. IH and IF basis distributions have significant seasonal characteristics, strengthening seasonally from May to July mainly due to the dividend effect [3][60][61]. - Investor expectations, market sentiment, and capital behavior are key forces driving short - term basis fluctuations, with significant varietal heterogeneity in the impact. When market sentiment warms up or the margin balance expands, the basis tends to narrow, and this effect is more sensitive and intense in small - and mid - cap varieties. The stock market volatility index is positively correlated with the basis. The large - scale inflow of north - bound funds usually supports the spot price and helps the basis expand, but the recent data has gaps. The significant decline in the shareholding ratio of long - term institutional funds such as insurance and social security may weaken the spot pricing anchor and increase the forward risk premium of the market, intensifying the futures discount [4][61]. - Index dividends are a definite fundamental factor causing regular seasonal fluctuations in the basis. There is a significant positive correlation between the dividend rate and the basis, and the higher the dividend concentration, the stronger the impact. During the dividend peak from May to July each year, the futures of Shanghai Stock Exchange 50 (IH) and CSI 300 (IF) stock index futures are usually in deep discount, which provides a clear layout window for calendar - effect - based arbitrage and hedging strategies [4][62]. 3. Summary according to the Directory 3.1 Chapter 1: Historical Distribution and Statistical Laws of Stock Index Futures Basis - **Core Statistical Features and Differences between Varieties**: Based on historical data from 2023 to 2026, the basis of the four major stock index futures shows significant varietal differentiation. The basis level presents a style gradient of IM > IC > IF/IH, and the basis volatility also shows a similar style differentiation. The statistical features of the IH variety are special, with a low basis mean and volatility, but extreme basis deviations may occur, indicating potential arbitrage opportunities [10][11]. - **Time - Series Features and Seasonal Laws**: The basis has obvious quarterly effects. The monthly average of the basis is significantly higher from May to July due to the dividend effect, and the futures are more likely to be in a premium state in the fourth quarter, which may be related to year - end market liquidity, institutional investors' portfolio adjustments, and expectations for the next year's corporate performance [12][14]. - **Distribution Form and Normal Distribution Test**: The basis distribution forms of different varieties vary. The basis distributions of IH, IF, and IC are more concentrated, while that of IM is flatter. All have leptokurtic and thin - tailed distribution features, which have dual implications for trading practice [23][25]. 3.2 Chapter 2: Influence Mechanism of Investor Expectations and Market Sentiment on Stock Index Futures Basis - **Linkage Mechanism between Market Sentiment and Basis and Varietal Heterogeneity**: Market sentiment is positively correlated with the basis, but the sensitivity of different style index futures varies. When the market sentiment index rises, the basis tends to narrow, and this effect is more obvious in small - and mid - cap stock index futures. The margin balance is also indirectly related to the basis, and the stock market volatility index is positively correlated with the basis [35][36][37]. - **Transmission Path and Influence of Policy Expectations on the Basis**: Monetary policy and stock index futures regulatory policies affect the basis. Monetary policy has a complex impact on the basis through changing the risk - free interest rate and liquidity environment. The stability of regulatory policies provides a institutional basis for the market - based formation of the basis [41][42]. 3.3 Chapter 3: Analysis of the Seasonal Influence of Index Dividends on Stock Index Futures Basis - **Core Facts of Dividend Season Distribution and Seasonal Performance of the Basis**: Index component stock dividends are concentrated in the second and third quarters, leading to significant seasonal characteristics of the basis. The impact of dividends on the basis of different varieties varies, with IH and IF being more significantly affected [44][45]. - **Practical Application and Strategy Considerations Based on Dividend Seasonality**: The predictable seasonal influence of dividends provides a strategy layout window. During the dividend season, there may be opportunities for reverse cash - and - carry arbitrage. Establishing a dividend monitoring system is crucial [48]. 3.4 Chapter 4: Influence Mechanism of Market Capital Behavior on Stock Index Futures Basis - **Analysis of the Influence Mechanism of Various Capital Behaviors on the Basis**: Margin trading funds affect the basis by changing the supply - demand balance in the spot market. The shrinkage of short - selling balance may lead to an increase in futures discount. North - bound funds affect the basis by influencing the spot pricing anchor, but data gaps exist. The reduction of long - term institutional funds' shareholding may lead to an increase in the basis [50][51][52]. - **Interpretation of the Current Market Structure and Future Observation**: In March 2026, the deep discount structure of the four major stock index futures may be the result of the combined action of various capital behaviors. Follow - up monitoring dimensions include the inflection point of short - selling balance, the authenticity verification and tracking of institutional holdings, and the linkage between capital cost and basis rate [53][54]. 3.5 Chapter 5: Analysis of the Current Stock Index Futures Basis Situation and Market Structure - **Current Basis Level and Term Structure Features**: As of March 25, 2026, all varieties of futures are in a discount state, and the far - month discount deepens. There are significant differences in basis rates between varieties, with IH having the lowest basis rate and IM having the highest [56]. - **Strategy Considerations and Risk Monitoring under the Current Basis Structure**: For cash - and - carry arbitrageurs, reverse arbitrage is theoretically the main direction, but practical execution is difficult. Key risk monitoring dimensions include sudden changes in capital interest rates, reversals of market sentiment, early reactions to dividend season expectations, and signs of style switching [58][59]. 3.6 Chapter 6: Summary The report systematically studies the basis performance of the four major stock index futures from January 1, 2023, to March 25, 2026, and finds relevant laws of basis changes, including style stratification of basis level and volatility, the influence of investor expectations, market sentiment, and capital behavior on short - term basis fluctuations, and the seasonal influence of index dividends on the basis [60].

Group 1: Report Industry Investment Rating - No relevant content Group 2: Core Viewpoints - The short - term and medium - term views of the index futures are range - bound, with an intraday view of being weak [1][5] - The core logic is the balance between continuous policy support and the uncertainty of the Middle - East geopolitical crisis, with investors showing weak trading willingness but limited downside for the index due to macro - economic resilience and policy benefits [1][5] Group 3: Summary by Related Catalogs Variety Viewpoint Reference - For the IH2606 variety, the short - term view is oscillatory, the medium - term view is oscillatory, the intraday view is weak, and the overall view is range - bound. The core logic is the contrast between continuous policy benefits and the Middle - East geopolitical crisis [1] Main Variety Price Market Driving Logic - For IF, IH, IC, and IM varieties, the intraday view is weak, the medium - term view is oscillatory, and the reference view is range - bound. Yesterday, the stock indices were oscillating, showing a trend of hitting bottom and then rebounding. The Middle - East geopolitical situation is highly uncertain, leading investors to be risk - averse. However, the impact of external risks on China's macro - economy has been digested, and with strong economic resilience and continuous policy benefits, the downside of the index is limited [5]

Group 1: Report Industry Investment Rating - No relevant content Group 2: Core View of the Report - The short - term view of IF, IH, IC, and IM is weak, the medium - term view is oscillatory, and the reference view is range - bound. It is expected that the stock index will mainly fluctuate in a range in the short term [5]. Group 3: Summary According to the Catalog 1. Variety View Reference - Financial Futures Stock Index Sector - For IH2606, the short - term view is oscillatory, the medium - term view is oscillatory, the intraday view is weak, and the reference view is range - bound. The core logic is the contrast between continuous policy benefits and the Middle East geopolitical crisis [1]. 2. Main Variety Price Market Driving Logic - Financial Futures Stock Index Sector - Last Friday, each stock index rebounded oscillatory. The Middle East geopolitical situation is the main factor affecting the short - term trend of the stock index. The information released by the US and Iran on the US - Iran peace talks has a huge difference, with high uncertainty in reaching an agreement. Although the Middle East geopolitical risk has cooled to some extent, investors' risk preference is cautious. The trading volume of the Shanghai and Shenzhen stock markets has continued to shrink. From the perspective of the stock market's own fundamentals, domestic policies are continuously beneficial to the economic fundamentals, and there is still support for the stock index in the medium and long term [5].

1. Report Industry Investment Rating - No relevant content provided 2. Core View of the Report - The conflict between the US and Iran is recurring, and Trump's verbal intervention is losing effectiveness. Rising energy prices and increasing inflation have led to a decline in expectations of a Fed rate cut and even a shift towards rate hikes. The probability of a rate hike by traders has exceeded 50% for the first time, causing an increase in US bond yields and suppressing the valuation of global risk assets. In China, the narrowing of PPI and strong profitability of industrial enterprises at the beginning of the year, along with energy self - sufficiency and reserve advantages, have maintained export resilience. The short - term market may continue to fluctuate, but the medium - to - long - term strategy is mainly to go long on dips [11]. 3. Summary by Directory 3.1 Week - to - Week Assessment and Strategy Recommendation - **Important News**: Iran rejected the 15 - point cease - fire agreement proposed by the US and demanded that the US stop aggression.

Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Report's Core View - The short - term view of the stock index is mainly low - level oscillation. At present, the geopolitical crisis in the Middle East has increased the risk of macro - recession, the market sentiment is weak, but in the long - term, the domestic policy is continuously beneficial to the economic fundamentals, and there is still supporting power for the stock index [5]. 3. Summary by Relevant Catalogs 3.1 Variety View Reference - Financial Futures Stock Index Sector - For the IH2606 variety, the short - term view is oscillation, the medium - term view is oscillation, the intraday view is weak, and the overall view is interval oscillation. The core logic is the confrontation between continuous policy benefits and the Middle East geopolitical crisis [1]. 3.2 Main Variety Price Market Driving Logic - Financial Futures Stock Index Sector - The varieties include IF, IH, IC, IM. The intraday view is weak, the medium - term view is oscillation, and the reference view is interval oscillation. The core logic is that the stock index declined significantly yesterday, and the A - share trading volume did not increase significantly. The sharp correction of the stock index is due to the strong sentiment of capital leaving the market to wait and see under the high - risk uncertainty, resulting in a lack of liquidity in the stock market and insufficient buying support. With the continuous escalation of the Middle East geopolitical crisis, the risks of global energy supply shortage and key raw material supply chain interruption have increased, and the risk of global macro - economic weakening has risen significantly. The subsequent war situation is uncertain, and investors' preference for risky assets has declined rapidly. The Shanghai Composite Index has fallen significantly in the past two trading days, reflecting the weak market sentiment. In the long - term, domestic policies are beneficial to the economic fundamentals, and there is still support for the stock index [5].

Report Summary 1. Report Industry Investment Rating No information provided 2. Core Viewpoint - The current situation features a co - existence of macro - recession risks triggered by the Middle East geopolitical crisis and continuous policy benefits, leading to short - term range - bound fluctuations in stock index futures [5]. 3. Summary by Relevant Catalogs 3.1 Variety Viewpoint Reference - Financial Futures Stock Index Sector - For IH2606, the short - term view is "oscillation", the medium - term view is "oscillation", the intraday view is "bullish", and the reference view is "range - bound oscillation". The core logic is the balance between continuous policy benefits and the Middle East geopolitical crisis [1]. 3.2 Main Variety Price Market Driving Logic - Financial Futures Stock Index Sector - The intraday view for IF, IH, IC, and IM is "bullish", and the medium - term view is "oscillation", with a reference view of "range - bound oscillation". The core logic is that last Friday, stock indexes oscillated and declined. The escalating Middle East geopolitical crisis has increased risks such as global energy supply shortages, raw material supply chain disruptions, and macro - economic weakening. Investor risk appetite has significantly declined. However, continuous policy benefits strongly support the stock index. Policy measures can stabilize corporate profit expectations and the stock market's fundamental expectations, and may also introduce liquidity support policies or play a role similar to a stabilization fund [5].
