Core Viewpoint - The article discusses the significant weekly drawdown in market-neutral strategies by quantitative private equity firms, attributing it to three main reasons: poor Alpha environment, unfavorable style Beta, and substantial convergence of basis [2][3][6]. Group 1: Reasons for Drawdown - The Alpha environment was poor, with the average stock in the market only rising by 2.0% and the median increase being just 0.36%, indicating insufficient overall market momentum [6]. - There was a notable structural differentiation in the A-share market, with the CSI 1000 index leading with a 4.09% increase, while only 23% of stocks outperformed the CSI 1000 index, posing challenges for market-neutral strategies [6][10]. - The basis for the main futures contract used for hedging (IM2509) converged by over 1% within the week, leading to an additional 1% drawdown in product net value [6][7]. Group 2: Performance Summary - The market-neutral products experienced an approximate 3% drawdown due to the combined effects of a poor excess return environment, the strong performance of the CSI 1000 index, and the convergence of the basis [7]. - Despite the drawdown, firms believe that the overall basis environment will improve, allowing for recovery in market-neutral strategies [7][12]. Group 3: Company Profile - Qingdao Leang Asset Management Co., Ltd. was established in November 2018 and registered with the Asset Management Association of China in April 2019, with a registered capital of 10 million yuan [8]. - The company currently manages 32 private equity products with a management scale ranging from 2 billion to 5 billion yuan [7][8].

Core Viewpoint - The article discusses different levels of stock investment strategies and introduces the concept of market-neutral strategies as a way to mitigate market volatility and enhance returns [2][21]. Group 1: Investment Strategies - There are three levels of investment strategies: 1. **Beginner Level**: Randomly selecting stocks, which can lead to high volatility and uncertain profits [5][7]. 2. **Intermediate Level**: Selecting stocks based on specific criteria, such as market capitalization, which reduces volatility compared to individual stocks [9][11]. 3. **Advanced Level**: Selecting stocks from a pool based on multiple criteria, often using quantitative strategies to achieve excess returns [13][15]. Group 2: Market-Neutral Strategies - Market-neutral strategies involve going long on stocks expected to outperform the market while simultaneously shorting core indices using stock index futures [23][24][26]. - The cost of hedging in these strategies is referred to as the basis, which is the difference between spot prices and futures prices [28][33]. - In the domestic market, a common situation is that the spot price exceeds the futures price, leading to a state known as contango [30]. - An example illustrates the potential outcomes of a market-neutral strategy based on the relationship between spot and futures prices at expiration [34][36].

Core Viewpoint - The recent low level of stock index futures basis is linked to the dynamics of Dynamic Coupon Notes (DCN) products, which are believed to potentially reduce the basis rather than deepen it [1][4][31]. Group 1: Stock Index Futures Basis - The recent basis rates for IC and IM have reached historical lows, influenced by factors such as hedging, trading, dividend cycles, and policy restrictions [2][6]. - The basis rates are expected to exhibit cyclical fluctuations, with the current deep basis potentially benefiting the yield and scale of structured products like DCN and snowball products [2][7]. - The basis rates for IC and IM, after adjusting for dividends, remain at historical lows, indicating persistent pressure on the stock index futures market [8][9]. Group 2: Dynamic Coupon Notes (DCN) - DCN is characterized as a type of snowball product without an observation for knock-in, providing fixed income features combined with derivatives [3][25]. - The structure of DCN allows for monthly interest payments if the index price meets certain thresholds, with a risk of loss if the index falls below a specified level at maturity [25][30]. - The hedging mechanism of DCN is smoother compared to traditional snowball products, as it lacks a knock-in feature, resulting in a more stable impact on the stock index futures market [4][31]. Group 3: Market Dynamics and Product Scale - The total scale of snowball-like structured products is estimated to be around 100 billion yuan, which is less than half of the scale at the beginning of 2024 [4][31][38]. - The recent deep basis in stock index futures is expected to lead to a rapid increase in the yield and scale of DCN and similar structured products [4][45]. - The issuance of DCN products is seen as attractive in a low-interest environment, potentially leading to increased demand and market activity [4][31].

Report Overview - The report is a private equity fund special report focusing on the long - end analysis of market neutral strategies: quantitative stock selection, titled "How the Model Determines Your Return Cap" and is part of the Huabao Aggregation series of popular science articles [1] Core Viewpoint - The market neutral strategy, as an important pillar of the absolute return system, provides investors with a relatively stable return path through a long - short hedging mechanism [11] Section Summaries Market Neutral Strategy Long - end Construction Logic and Operational Characteristics - The long - end of the stock market neutral strategy constructs a stock portfolio with excess return capabilities through a systematic method, using a multi - level screening mechanism including initial screening based on core factors, further identification of targets, and dynamic adjustment to maintain risk balance. The strategy's return comes from the excess return difference between the long portfolio and the hedging instrument, and managers need to monitor key indicators and optimize the portfolio structure. The effectiveness of the quantitative stock - selection model is restricted by the market environment and requires parameter adjustment [5] Domestic Quantitative Model Development History - The development of the stock market neutral strategy's stock - selection method is coordinated with the capital market regulatory system. It has evolved from qualitative fundamental analysis in the early stage to the use of linear multi - factor models, and then to non - linear machine learning models and neural network models, affected by regulatory policies and market events such as the launch of margin trading and short - selling, the abnormal market fluctuations in 2015, and the implementation of registration systems [6] Secrets of Surviving Bull and Bear Markets: Survival Rules and Winning Logic of Neutral Strategies - The construction of quantitative models needs to balance historical rules and real - world changes. Investors should evaluate the strategy's full - cycle adaptability and the manager's ability to control drawdowns in special periods. Managers need to maintain the stability of core factors and establish a fast - response channel for new feature mining [7] How to Evaluate the Long - end of Market Neutral Strategies - Evaluating the long - end of market neutral strategies requires a multi - dimensional analysis framework, including examining the sustainability of returns and the completeness of the risk - control system. Ordinary investors should focus on the verifiability of the strategy's underlying logic, historical maximum drawdown, and the manager's ability to respond to market structure changes [9] Avoiding Three Cognitive Traps for Successful Neutral Strategy Investment - Investors should be aware of three cognitive blind spots: clarifying the essence of stock - selection logic, understanding the value of diversified allocation, and recognizing the inherent risk boundaries of the strategy. They should also check if the manager has a complete extreme stress - testing system [10]
