Report Overview - The report introduces the ETF arbitrage strategy, a unique absolute return strategy that accumulates small price differences into stable returns [7]. ETF Core Features - ETF, or "Exchange-Traded Fund", is a "transparent basket" that can be traded like stocks. It is an open-ended fund listed on the exchange, with its net value publicly disclosed daily [8]. - ETF has two trading markets: the primary market, where investors can exchange a basket of assets for ETF shares, and the secondary market, where ETFs are traded like stocks. Price differences between the two markets create arbitrage opportunities [9][10]. ETF Arbitrage Strategy's Income Realization Path - The core logic is to capture and exploit short - term pricing deviations. The most common method is ETF redemption arbitrage, including discount and premium arbitrage. In discount arbitrage, buy ETFs in the secondary market and redeem them in the primary market; in premium arbitrage, buy a basket of assets to subscribe for ETFs in the primary market and sell them in the secondary market [12][13]. - There are also cross - market arbitrage and related - variety arbitrage, which are used as supplementary strategies due to fewer opportunities [15]. Key Features of ETF Arbitrage Strategy - Single - arbitrage profit margins are small, usually around 0.5% or lower. The final return depends on continuous accumulation [16]. - The strategy requires high - speed and timely trading. Opportunities are fleeting, and all arbitrageurs compete to compress expected returns [16]. - The strategy faces challenges such as high trading costs, potential calculation errors of asset values, restrictions on primary - market subscriptions and redemptions, and increased complexity during extreme market conditions [17].

Quantitative Factors and Models Summary Quantitative Factors and Construction Methods 1. **Factor Name**: Market Style Factor **Construction Idea**: This factor tracks the market's preference for small-cap versus large-cap stocks and growth versus value stocks over the observed period **Construction Process**: - The factor is divided into two dimensions: size (small-cap vs. large-cap) and style (growth vs. value) - The factor measures the relative performance of small-cap stocks compared to large-cap stocks and growth stocks compared to value stocks - Observations include the directional bias (e.g., small-cap preference) and the volatility of these style preferences **Evaluation**: The factor indicates a market preference for small-cap and growth stocks, but with increased volatility, suggesting instability in market style trends [11][12] 2. **Factor Name**: Market Structure Factor **Construction Idea**: This factor evaluates the dispersion and concentration of returns across industries and stocks to assess market structure dynamics **Construction Process**: - Industry excess return dispersion is calculated to measure the spread of returns across different sectors - Metrics such as the proportion of rising constituent stocks and the turnover concentration of the top 100 stocks and top 5 industries are tracked - Changes in these metrics are used to infer market structure stability and concentration trends **Evaluation**: The factor shows a decline in industry return dispersion and a slight increase in stock and industry concentration, indicating a more concentrated market structure [11][12] 3. **Factor Name**: Market Activity Factor **Construction Idea**: This factor measures market activity through volatility and turnover rates **Construction Process**: - Index volatility is calculated to assess market fluctuations - Turnover rates, particularly for indices like the SSE 50, are tracked to gauge trading activity - Observations include changes in these metrics over time **Evaluation**: The factor reveals a slight increase in market volatility but a continued decline in turnover rates, especially for the SSE 50, indicating reduced market activity [11][12] 4. **Factor Name**: Commodity Market Factors **Construction Idea**: These factors analyze trends, momentum, volatility, and liquidity in commodity markets **Construction Process**: - **Trend Strength**: Tracks the continuation of trends in sectors like energy and metals - **Basis Momentum**: Measures the momentum of basis changes, with specific focus on sectors like agriculture and metals - **Volatility**: Assesses the level of price fluctuations in different commodity sectors - **Liquidity**: Evaluates the trading activity and ease of transactions in commodity markets **Evaluation**: The factors highlight strong trends in energy and metals, low basis momentum in agriculture, high volatility in energy, and strong liquidity in energy and metals [23][27] 5. **Factor Name**: Option Market Factors **Construction Idea**: These factors assess market sentiment and risk expectations through option pricing metrics **Construction Process**: - **Implied Volatility**: Tracks the implied volatility of options on indices like SSE 50 and CSI 1000 - **Skewness**: Measures the relative pricing of put options versus call options to infer market sentiment - **Open Interest**: Monitors changes in open interest to gauge market positioning **Evaluation**: The factors suggest stable short-term sentiment but highlight potential downside risks for small-cap stocks based on skewness and rising open interest in put options [33][34] 6. **Factor Name**: Convertible Bond Market Factors **Construction Idea**: These factors analyze valuation and liquidity dynamics in the convertible bond market **Construction Process**: - **Valuation Metrics**: Tracks metrics like the premium rate of bonds near par value and the proportion of low-premium bonds - **Liquidity Metrics**: Monitors trading volume and credit spreads **Evaluation**: The factors indicate a slight recovery in valuation metrics but a rise in low-premium bonds, with stable trading volumes and narrowing credit spreads [35][37] Factor Backtesting Results 1. **Market Style Factor**: - Small-cap preference observed - Growth style preference observed - Increased volatility in both dimensions [11][12] 2. **Market Structure Factor**: - Industry return dispersion decreased - Stock and industry concentration slightly increased [11][12] 3. **Market Activity Factor**: - Market volatility slightly increased - Turnover rates decreased, especially for SSE 50 [11][12] 4. **Commodity Market Factors**: - Strong trends in energy and metals - Low basis momentum in agriculture - High volatility in energy - Strong liquidity in energy and metals [23][27] 5. **Option Market Factors**: - Stable implied volatility for SSE 50 and CSI 1000 - Skewness favors put options for CSI 1000 - Rising open interest in put options for CSI 1000 [33][34] 6. **Convertible Bond Market Factors**: - Premium rates near par value slightly recovered - Proportion of low-premium bonds increased - Trading volumes stable - Credit spreads narrowed [35][37]

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - Last week (2025.05.26 - 2025.05.30), the bond market oscillated and closed lower. The CBA00201 index basically closed flat, while the CBA00203 index closed down 0.08%. Yields of interest - rate bonds generally rose, with short - term yields rising more than long - term ones. Credit bond yields also generally increased, and major credit spreads mainly compressed [3][10]. - The capital market was relatively loose, but the economic fundamentals remained weak. The tariff policy was volatile, putting pressure on US Treasury bonds. The popularity of REITs continued, and assets were accelerating into the market [3]. - On May 29, 2025, the general pledge repurchase business of the first 9 credit bond ETFs was officially launched, which is conducive to the rapid development of the credit bond ETF market [4]. Summary by Directory 1. Weekly Market Observation 1.1. Pan - fixed - income Market Review and Observation - **Bond Market Review**: The bond market oscillated and closed lower last week. Interest - rate bond yields generally rose, and credit bond yields also increased. Major credit spreads mainly compressed. Specifically, from Monday to Wednesday, short - term credit bond yields rose, and long - term ones oscillated. On Thursday and Friday, due to the change in Trump's tariff policy, credit yields fluctuated significantly following interest rates [10]. - **Capital and Economic Fundamentals**: In May, the capital market was generally loose. After the interest rate cut and reserve requirement ratio cut, the monthly central levels of R001 and R007 declined. Affected by the end - of - month effect last week, the central level of R007 rose slightly to 1.70%. The economic fundamentals were still weak. Although the high - frequency data rebounded due to the rush to export after the reciprocal tariff reduction, domestic demand remained weak. The May PMI rebounded seasonally, but the manufacturing PMI was still below 50%. The new export orders in the manufacturing industry rebounded but were still lower than the March data and the first - quarter average. High - frequency data showed an increase in container shipping bookings to the US, which might improve the June fundamentals. However, domestic demand - priced commodities such as rebar, cement, glass, and asphalt saw price declines. The bond market faces both positive and negative factors, and a cautious approach of high - selling and low - buying may be appropriate [11]. - **Tariff Policy and US Treasury Bonds**: Since the reciprocal tariff implementation, US Treasury bonds have experienced two significant declines. In May, after the three major rating agencies downgraded US Treasury bonds, the market re - evaluated US debt risks. Last week, due to stable US economic data and a court ruling, US Treasury bonds rebounded slightly. Currently, the trading focus of US Treasury bonds has shifted back to the US fundamentals. There are risks of disorderly increases in US Treasury bond yields due to fiscal risks and tariff uncertainties. The stable US fundamentals have postponed the expected time of the Fed's interest rate cut, and tariff issues may reduce overseas demand for US Treasury bonds and cause short - term liquidity problems [12]. - **REITs Market**: REITs have both equity and bond characteristics. This year, due to factors such as the decline in bond yields and the expectation of economic recovery, the popularity of REITs has continued, with property - type assets performing better. After the asymmetric interest rate cut, REITs have entered a high - level consolidation phase, but some specific assets still have upward momentum. In the primary market, high - quality assets are entering the market at an accelerated pace. Last week, the expansion of two REITs was approved. Overall, the C - REITs market is in a stage of rapid expansion, but there are risks in the primary and secondary markets [13]. 1.2. Public Fund Market Dynamics - On May 29, 2025, the general pledge repurchase business of the first 9 credit bond ETFs was officially launched, expected to take effect on June 6. This business can broaden financing channels for investors, improve capital efficiency, and promote the development of the credit bond ETF market. Its application scenarios include obtaining liquidity through pledge, quickly switching asset allocation, and increasing returns through leverage [4][15]. 2.
