1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - The market overestimates the proportion of active equity funds underperforming their benchmarks. Selecting a benchmark that matches the fund manager's style can significantly reduce the proportion of funds with performance 10% lower than the benchmark [3][19] - The S&P 500 is the most widely - chosen benchmark for active equity funds in the US, and Russell style indices are also highly recognized [24][25] - In the short - term, banks, non - banks, and food and beverage are under - allocated industries, while electronics, media, and machinery are over - allocated industries. Active equity funds in Hong Kong still prefer growth - oriented industries [3][38][43] - When selecting a performance comparison benchmark, factors such as index style suitability, market recognition, stability, investment opportunities, and long - term viability should be considered [3] 3. Summary According to the Table of Contents 3.1 Market Overestimates the Proportion of Active Equity Funds Underperforming Their Benchmarks 3.1.1 Problems of Directly Selecting Broad - based Indices as Benchmarks - The two simple calculation methods currently used in the market may not have reference value for the future. The data on the proportion of funds underperforming benchmarks in the past has randomness and cannot reflect the true ability of active equity funds [10][11] - If fund managers choose broad - based indices as benchmarks without changing their investment strategies, the probability of their performance being more than 10% lower than the benchmark in three years is uncontrollable. Selecting a benchmark that matches the investment style is more important [16][19][20] 3.1.2 Benchmarks Used by Overseas Active Equity Funds - In the US, the S&P 500 is the most widely - chosen benchmark, with a scale proportion of over 40% in all active products investing in the US. Russell style indices such as Russell 1000 Growth and Russell 1000 Value are also highly recognized [24][25] - Different types of US active funds have different benchmark selection preferences. For example, the S&P 500 is commonly chosen for large - cap core products, while Russell 2000 is dominant in small - cap core products [26] 3.2 Short - term Market Transaction Expectations 3.2.1 Industry and Stock Dimensions: Under - allocation of Finance and Traditional Consumption, Over - allocation of Technology and Growth - Balanced style funds under - allocate non - banks, banks, and food and beverage, and over - allocate media, automobiles, and machinery. Growth style funds under - allocate food and beverage, transportation, and public utilities, and over - allocate electronics, power equipment, and machinery. Value style funds under - allocate banks, non - banks, and building decoration, and over - allocate power equipment, real estate, and pharmaceutical biology [33][34][35] - Different industry - themed funds also have different over - and under - allocation situations. Overall, banks, non - banks, and food and beverage are industries with large under - allocation amounts, while electronics, media, and machinery are industries with large over - allocation amounts [38] 3.2.2 Hong Kong Stock Allocation: Over - and Under - allocation Relative to the Hang Seng Index - In Hong Kong stocks, under - allocated industries include banks, non - banks, and commerce and retail, while over - allocated industries include pharmaceutical biology, media, and electronics. Active equity funds in Hong Kong still prefer growth - oriented industries [43] 3.3 How to Select Performance Comparison Benchmarks for Active Equity Funds 3.3.1 Indices Currently Issued by Mainstream Index Companies - Active equity funds commonly choose broad - based indices, industry - themed indices, and SmartBeta products as performance comparison benchmarks. The top 5 most - tracked indices are usually broad - based indices such as the CSI 300, CSI 800, Hang Seng Index, CSI 500, and CSI Hong Kong Stock Connect Composite [46] - Mainstream index companies issue three types of indices: broad - based indices, SmartBeta indices, and industry - themed indices, covering multiple markets and strategies [49] 3.3.2 Indices More Likely to Generate Excess Returns - Three factors affect a fund's excess returns: investment ability, investment breadth, and investment opportunities. Indices with wider coverage and more investment opportunities can generate higher excess returns, but their Beta may be weaker [53][57] 3.3.3 How to Select Broad - based Indices - From multiple perspectives such as industry allocation deviation, standard deviation of component stock returns, and stock - selection tolerance, the CSI A500 index is more in line with the investment styles of most fund managers [61]
