Core Viewpoint - The article systematically categorizes A-share listed companies into four lifecycle stages: startup, growth, maturity, and consolidation, based on cash flow, and constructs optimal investment portfolios for each stage, achieving significant excess returns compared to benchmark indices since 2016 [1][3][61]. Lifecycle Stage Characteristics - Startup companies typically have small market capitalizations, unstable profitability, low dividend yields, and high R&D investments [2][18]. - Growth companies show improving profitability with evenly exposed factors [2][18]. - Mature companies are characterized by large market capitalizations, stable profitability, high dividend payout ratios, and healthier capital structures with lower debt ratios [2][18]. - Consolidation companies experience reduced scale, lower profitability, low dividend yields, and higher leverage, leading to greater debt repayment pressures [2][18]. Performance Characteristics of Investment Portfolios - The maturity portfolio exhibits the highest stability, with an annualized return of 16.9% since 2016, and positive excess returns relative to common indices in most years [3][51]. - The growth portfolio's performance is closely aligned with market indices, while startup and consolidation portfolios show higher volatility and lower returns [19][24]. - The performance of different lifecycle stage portfolios varies, with the mature portfolio providing the best defensive characteristics and cumulative returns over time [19][24]. Factor Performance Across Lifecycle Stages - Different lifecycle stages exhibit distinct factor characteristics, with low volatility and low turnover anomalies performing best in the riskier startup and consolidation stages [22][24]. - Fundamental factors vary by stage: startups focus on profitability improvement and net profit growth, growth stocks emphasize analyst profit forecast adjustments, and mature stocks prioritize growth acceleration factors [22][24][58]. Optimal Investment Combinations - The article constructs optimal investment combinations for each lifecycle stage, considering investment logic and factor effectiveness [25][51]. - The startup portfolio aims to select companies with improving profitability and net profit growth, achieving an annualized excess return of 13.4% compared to the basic pool [26][30]. - The growth portfolio focuses on high-growth companies with improved profitability, yielding an annualized excess return of 13.5% [33][39]. - The mature portfolio emphasizes companies with stable profitability and growth potential, achieving an annualized excess return of 11.2% [42][43]. - The consolidation portfolio, despite its inherent risks, utilizes multi-factor strategies to enhance returns, achieving an annualized excess return of 15.0% [46][49]. Comparative Analysis of Lifecycle Stages - The article highlights the increasing number of mature companies in the A-share market, which has grown 2.6 times over the past decade, reflecting a shift in the maturity of companies [8]. - The distribution of lifecycle stages varies significantly across different boards, with the main board having a balanced mix of growth and mature companies, while the ChiNext board is predominantly growth-oriented [12][57].

Core Viewpoint - The article systematically categorizes A-share listed companies into four lifecycle stages: startup, growth, maturity, and consolidation, based on cash flow, and constructs corresponding optimal portfolios for each stage, achieving annualized excess returns of 14.0%, 15.0%, and 19.5% relative to benchmark indices since 2016 [1][3]. Group 1: Lifecycle Stages Characteristics - Startup companies typically have smaller market capitalizations, unstable profitability, and low dividend yields, but invest heavily in R&D [1]. - Growth companies show improved profitability with a balanced exposure across various factors [1]. - Mature companies are characterized by large market capitalizations, stable profitability, high dividend payout ratios, and healthier capital structures with lower debt ratios [1]. - Consolidation companies experience reduced scale, poorer profitability, lower dividend yields, and higher leverage with significant debt repayment pressures [1]. Group 2: Performance and Risk Characteristics - The buy-and-hold combinations across different lifecycle stages exhibit varying risk-return profiles, with mature companies showing the most stability and highest cumulative returns over time [2]. - Growth stock portfolios perform closely to market indices, while startup and consolidation stock portfolios exhibit higher volatility and lower returns [2]. - Factor performance varies across lifecycle stages, with low volatility and low turnover rates performing best in the riskier startup and consolidation phases [2]. Group 3: Optimal Portfolio Construction - The company constructs optimal portfolios for each lifecycle stage considering investment logic, factor effectiveness, and correlations, with the mature portfolio demonstrating the highest stability and an annualized return of 16.9% since 2016 [2]. - The mature portfolio has shown positive excess returns relative to common broad indices like the CSI All Share Index, CSI 300, and CSI 800 in most years, except for a 12% decline in 2018 [2].
