Report Industry Investment Rating - Not provided in the content Core Viewpoints of the Report - In Q1, the price of the underlying assets showed a trend of rising first and then falling. In January and February, the positive policy expectations of the Two Sessions continued to ferment, and the stock indices oscillated and rose. Among them, CSI 500 and CSI 1000 related to small and medium - cap stocks had relatively large increases. In March, the Middle East geopolitical crisis broke out, the risk of global macro - economic recession increased, the risk appetite of the stock market weakened rapidly, and the stock indices were under full - pressure decline [5][10][35]. - Recently, the option position PCR has shown a bottom - up trend, indicating that market sentiment has improved, the worst situation of the geopolitical conflict has been gradually digested by the market, and the market sentiment remains at a low level. Currently, the at - the - money implied volatility of options is at a normal quantile level. From the perspective of volatility, the relative advantages of option buyers and sellers are not obvious, and the market sentiment tends to be stable [5][19][35]. - The disturbance of the Middle East geopolitical situation is the main factor affecting the short - term trend of the stock index. High - uncertainty risks suppress the risk appetite of the stock market. In the long - term, the continuous positive policy and the continuous inflow of funds into the stock market still constitute the core logic for the medium - and long - term upward movement of the stock index. It is expected that the stock index will maintain range - bound consolidation in the short - term. Considering that the long - term upward logic still exists, a bull spread portfolio can be used to deal with the difficulty of timing in the volatile market [5][33][35]. Summary According to the Directory 1 Market Review - There are 12 listed financial options in China's stock index financial derivatives market, including 9 ETF options and 3 stock index options, which are closely related to 7 indices. This report mainly analyzes options related to 4 broad - based indices [9]. - As of March 27, in Q1, the price of the underlying assets showed a trend of rising first and then falling. In January and February, due to positive policy expectations, the stock indices rose. In March, affected by the Middle East geopolitical crisis, the stock indices declined [10]. 2 Option Analysis Indicators 2.1 Position PCR Low - level Oscillation - The Put - Call - Ratio (PCR) is used to measure the long - short state of the market. The position PCR reflects the long - short sentiment contrast in the market. Since March, the position PCR of each option has rapidly declined and is now at a low historical quantile level, indicating that market sentiment has weakened rapidly. Recently, the position PCR has shown a bottom - up trend, indicating that market sentiment has improved [19]. 2.2 Implied Volatility Rising and Then Falling - Volatility is a key factor in option pricing and trading. In March, with the outbreak of the Middle East geopolitical crisis, the at - the - money implied volatility of options rose rapidly and then fell. Currently, it is at a normal quantile level, and the relative advantages of option buyers and sellers are not obvious, and the market sentiment tends to be stable [23]. 3 Underlying Asset Trend Analysis - The continuous positive policy and the continuous inflow of funds into the stock market constitute the core logic for the medium - and long - term upward movement of the stock index. The policy has clear expectations of supporting total demand and scientific and technological innovation. The government work report announced on March 5 proposed a series of fiscal policies to support demand, and policies to develop new industries, which support the relevant indices. The trend of incremental funds flowing into the stock market remains unchanged. As of March 5, A - share margin trading data showed that margin trading can boost the market, and new equity - biased funds in January and February were at a high level, indicating strong enthusiasm for "investing in the market through funds" [26][27][31]. - The Middle East geopolitical crisis is the main factor affecting the short - term trend of the stock index. After the crisis, global stock market risk appetite shrank due to uncertainty, energy shock, and liquidity tightening expectations. The information difference between the US and Iran on peace talks means high uncertainty, and the trading volume of the Shanghai and Shenzhen stock markets has shrunk, indicating cautious market sentiment [32]. 4 Option Portfolio Viewpoints - In the short - term, the stock index will maintain a range - bound trend. Considering the long - term upward logic, a bull spread portfolio can be used to deal with the difficulty of timing. A bull call spread portfolio can be selected, which involves buying low - strike - price call options and selling the same number of high - strike - price call options. It has limited risk and can design the expected profit - and - loss curve by selecting the strike prices [34]. 5 Summary - It summarizes the trend of the underlying asset price in Q1, the changes in option position PCR and implied volatility, the impact of the Middle East geopolitical situation on the short - term and long - term trends of the stock index, and suggests using a bull spread portfolio to deal with the volatile market [35].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Last week, the bond futures showed a differentiated trend, with the 30 - year main contract rising by 0.45%, the ten - year main contract falling by 0.01%, the five - year main contract rising by 0.01%, and the two - year main contract falling by 0.01%. The market risk preference gradually weakened, activating the hedging attribute of bond futures. The downward trend of bond futures is not likely to reverse when the long - term bullish logic of the stock market remains unchanged and the coupon income of bonds is not very attractive. Only when the expected return of equity or risk assets declines marginally, the short - term hedging trading attribute of the bond market becomes more obvious [6]. - Last week, domestic commodities remained highly volatile. Energy and chemical products showed a differentiated trend, with significant declines in crude oil and fuel oil, but sharp increases in some chemical products. The market's expectations regarding the situation in the Iranian region are still the focus of divergence and game. Most commodity factors declined, with significant drops in term - structure factors and slight declines in volatility, basis, and warehouse - receipt factors. Long - term trend and term - structure factors remain effective, and the gradual recovery of fundamental factors is worthy of future attention [13][15]. 3. Summary by Directory 3.1 Treasury Bond Futures Quantitative Strategy 3.1.1 Treasury Bond Futures Market Review - Last week, each bond futures contract showed a differentiated trend. The 30 - year main contract rose by 0.45%, the ten - year main contract fell by 0.01%, the five - year main contract rose by 0.01%, and the two - year main contract fell by 0.01%. The basis of each variety also showed a differentiated trend. The CTD bond of the ten - year bond was 250025, with a basis of about 0.06 yuan on the 27th, in line with the historical average. The CTD bond of the 30 - year bond was 210014, with a basis of 0.34 yuan on the 20th, higher than the historical average [6]. - The market risk preference gradually weakened, activating the hedging attribute of bond futures. The downward trend of bond futures is not likely to reverse when the long - term bullish logic of the stock market remains unchanged and the coupon income of bonds is not very attractive. Only when the expected return of equity or risk assets declines marginally, the short - term hedging trading attribute of the bond market becomes more obvious [6]. - For the ten - year treasury bond, in the out - of - sample period (from January 1, 2021, to the present), the annualized return, Sharpe ratio, and maximum drawdown of the portfolio under single - leverage are 2.71%, 1.27, and 2.04% respectively. Since the release of the report (from November 1, 2025, to the present), the annualized return, Sharpe ratio, and maximum drawdown of the portfolio under single - leverage are 2.62%, 1.61, and 0.67% respectively [6]. 3.1.2 Unilateral Strategy Performance - The unilateral strategy's performance is shown in the table. The annualized return, annualized volatility, annualized Sharpe ratio, maximum drawdown, and Calmar ratio in the full - sample period are 2.71%, 2.13%, 1.27, 2.04%, and 1.32 respectively. Since the report was released, these indicators are 2.62%, 1.63%, 1.61, 0.67%, and 3.88 respectively [9]. - The large - category factors include basis, intraday technical, intraday volume - price, high - frequency capital flow, member positions, and risk assets. The signal is generated by equal - weighting within each large - category factor and then taking the average, with the sign of the average as the long - short signal. The back - test details are that the strategy uses the VWAP of the first ten minutes of the next - day's opening as the trading price and buys with single - leverage [11]. 3.2 Commodity CTA Factor and Strategy Performance 3.2.1 Commodity Factor Performance - Last week, domestic commodities remained highly volatile. Energy and chemical products showed a differentiated trend, with significant declines in crude oil and fuel oil, but sharp increases in some chemical products. The market's expectations regarding the situation in the Iranian region are still the focus of divergence and game. Most commodity factors declined, with significant drops in term - structure factors and slight declines in volatility, basis, and warehouse - receipt factors. Long - term trend and term - structure factors remain effective, and the gradual recovery of fundamental factors is worthy of future attention [13][15]. 3.2.2 Tracking Strategy Performance - The performance of each tracking strategy is as follows: - CWFT strategy: Annualized return of 9.4%, Sharpe ratio of 1.62, Calmar ratio of 1.07, maximum drawdown of - 8.81%, recent one - week return of - 0.22%, and year - to - date return of 2.84% [14]. - C_frontnext & Short Trend strategy: Annualized return of 11.2%, Sharpe ratio of 1.70, Calmar ratio of 1.66, maximum drawdown of - 6.72%, recent one - week return of - 1.19%, and year - to - date return of 1.42% [14]. - Long CWFT & Short CWFT strategy: Annualized return of 12.6%, Sharpe ratio of 1.41, Calmar ratio of 0.96, maximum drawdown of - 13.07%, recent one - week return of - 0.84%, and year - to - date return of 5.56% [14]. - CS XGBoost strategy: Annualized return of 4.8%, Sharpe ratio of 0.78, Calmar ratio of 0.22, maximum drawdown of - 21.64%, recent one - week return of - 0.44%, and year - to - date return of - 5.86% [14]. - RuleBased TS Sharp - combine strategy: Annualized return of 11.4%, Sharpe ratio of 1.49, Calmar ratio of 1.38, maximum drawdown of - 8.26%, recent one - week return of - 0.75%, and year - to - date return of - 0.05% [14]. - RuleBased TS XGB - combine strategy: Annualized return of 10.8%, Sharpe ratio of 1.88, Calmar ratio of 2.18, maximum drawdown of - 4.95%, recent one - week return of - 1.08%, and year - to - date return of - 3.30% [14]. - CS strategies, EW combine strategy: Annualized return of 12.6%, Sharpe ratio of 1.80, Calmar ratio of 1.71, maximum drawdown of - 7.38%, recent one - week return of - 0.84%, and year - to - date return of 2.86% [14]. - Among the above six strategies, the CWFT strategy performed the best last week with a return of - 0.22%, and the Long CWFT & Short CWFT strategy performed the best year - to - date with a return of 5.56%.

1. Report Industry Investment Rating - Not provided in the given content 2. Core Views of the Report - **Stock Index Futures**: The market continued to rebound, but the divergence between bulls and bears intensified. The current market is a restorative rebound under the easing of geopolitical disturbances rather than a consistent reversal. It is advisable to observe changes in trading volume, open interest, and basis to judge the sustainability of the rebound [1][7]. - **Stock Index Options**: The implied volatility continued to decline, and the term structure improved. Before a clear stabilization, the options market shows "short - term game of rebound exit" and "medium - term put - selling strategy waiting", suggesting a cautious view on the future market [2][7]. - **Treasury Bond Futures**: The bond market oscillated narrowly, and attention should be paid to the US - Iran negotiations. Due to the uncertainty of the US - Iran negotiations, short - term inflation concerns still exist, and the bond market lacks upward momentum [3][8]. 3. Summary by Relevant Catalogs 3.1 Market Outlook - **Stock Index Futures**: Yesterday, the stock market rebounded, with small - cap and growth styles being stronger. The market was boosted by peace - talk news, and sectors such as non - ferrous metals, textiles, and communications led the rise. The current market is a restorative rebound, not a reversal. The reasons are tight trading volume, reduced margin trading balance, deepening basis, and uncertain geopolitical progress. The operation suggestion is to lightly position in IM after the right - side confirmation of capital indicators [1][7]. - **Stock Index Options**: On Wednesday, the equity market continued to rebound, and the total trading volume of financial options declined. The market risk - aversion sentiment eased, and the implied volatility of options decreased. The term structure returned to a state of lower near - term and higher far - term. Before clear stabilization, a defensive option - buying strategy is recommended, and attention can be paid to the opportunity of covered call strategy after the signal is clearer [2][7]. - **Treasury Bond Futures**: Most of the main contracts of treasury bond futures rose slightly. The central bank's reverse repurchase and MLF increased the net investment, and the capital market remained stable. Affected by the news of the US - Iran negotiation, the market risk preference improved, but due to the uncertainty of the negotiation, the bond market oscillated narrowly. The short - end is supported by loose capital, while the long - end may oscillate. Different strategies are provided for trend, hedging, basis, and curve [3][8]. 3.2 Derivatives Market Monitoring - **Stock Index Futures Data**: Not provided in the given content - **Stock Index Options Data**: Not provided in the given content - **Treasury Bond Futures Data**: Not provided in the given content

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - The risk appetite in the financial derivatives market is under pressure. The stock index futures showed a weak performance throughout the day, the volatility of stock index options soared and a defensive strategy should be maintained, and the trading of treasury bond futures was affected by the intertwined factors of risk - aversion and inflation concerns [1][2]. 3. Summary by Related Catalogs (1) Market Outlook Stock Index Futures - The equity market on Thursday opened lower and moved lower, with only a few industries such as coal and oil and gas rising against the trend. The reasons for the decline include a weaker liquidity environment, further fermentation of geopolitical situations, and a strong US dollar index. Currently, the option indicators imply that it has entered the second half of the adjustment. The operation suggestion is to hold the bottom - position of IM and wait for the geopolitical situation to become clear before making further layouts [7]. Stock Index Options - The trading volume of the option market soared back above the 10 - billion mark. The proportion of put options in multiple varieties increased significantly, and the overall volatility and skewness rose. Short - term hedging and multi - volatility trading both exist. It is not recommended to immediately layout short - volatility strategies after the volatility rises. The short - term main strategy is to maintain defense [7]. Treasury Bond Futures - Treasury bond futures rose across the board yesterday, but the T main contract weakened in the afternoon. The risk - aversion sentiment and inflation concerns are intertwined. The intensification of the Middle East geopolitical conflict has increased risk - aversion sentiment and may have driven the bond market. At the same time, rising oil prices have strengthened inflation concerns, restricting the bullish sentiment in the bond market. The central bank emphasized maintaining the stable operation of the financial market, and liquidity may remain abundant. The bond market may still have support. Operation suggestions include a trend strategy of range - bound trading, paying attention to short - hedging at low basis levels, paying attention to the basis opportunities of ultra - long - term bonds, and paying attention to the convergence opportunity of the 30Y - 10Y spread [8].

1. Report Industry Investment Rating - Not provided in the report. 2. Core Viewpoints of the Report - The stock market is under pressure, but the adjustment is expected to be controllable. The adjustment of stock index futures is tentatively considered controllable; the stock index option market is in the process of bottom - building sentiment, and short - term tail risks should be focused on; the bond market is supported by the loose capital situation [1]. - For stock index futures, on Tuesday, the equity market declined unilaterally, with the All - A index falling by more than 1.5%. The telecommunications, electronics, and military industries led the decline, while banks and insurance rose against the trend. The reasons for the decline are financial sector fund diversion and concerns about tail risks due to geopolitical conflicts. The attitude towards the decline space is relatively optimistic, and the operation is mainly to hold the bottom position and look for opportunities to replenish positions later. The end of March and early April are the observation windows [1][6]. - For stock index options, the underlying market opened high and closed low yesterday, and small and medium - cap stocks suffered a large intraday decline. The trading volume of the option market remained high, and the proportion of call option trading volume increased marginally, which is contrary to the market trend. The market is in the emotional bottom - building stage, and short - term call options should be bought to prevent tail risks [2][6]. - For treasury bond futures, the treasury bond futures rose across the board yesterday. The price of the T main contract first declined and then rose. Geopolitical conflicts and oil price fluctuations affect the bond market through inflation expectations, while the increasing motivation of allocation funds and the loose capital situation support the bond market. The cost - performance of bond allocation may rise again [3][8]. 3. Summary According to the Directory 3.1 Market Outlook - **Stock Index Futures**: The view is that the adjustment is controllable.

The logic is that the underlying market opened high and closed low, and the proportion of call option trading volume increased marginally. The suggestion is to buy options for defense [6]. - **Treasury Bond Futures**: The view is that the capital situation supports the bond market.
