Core Viewpoint - The article emphasizes the two fundamental logic of investment: taking on risk to earn risk premiums and capturing market mispricing, with a focus on factor investing as a primary strategy for the "Tianxingjian" fund portfolio [2]. Factor Investment Summary 1. Size Factor: The "Comeback" of Small Companies - The size factor focuses on smaller companies, which may offer excess returns due to their higher risk profile and potential undervaluation by larger institutions [4]. 2. Value Factor: The Wisdom of Buying "Cheap Goods" - The value factor targets companies with low valuations, where the risk premium arises from potential financial troubles and market overreactions to bad news, leading to mispricing [5][6]. 3. Quality Factor: The "Reward" for Good Companies - The quality factor emphasizes financially healthy companies, where excess returns may stem from investor short-sightedness and the undervaluation of stable firms [7]. 4. Dividend Factor: The "Charm" of Cash Cows - The dividend factor focuses on companies with stable and high dividend payouts, where the risk premium may relate to growth uncertainties or interest rate sensitivities, leading to systematic undervaluation [8]. 5. Low Volatility Factor: Steady Happiness - The low volatility factor targets companies with lower stock price fluctuations, where excess returns may arise from market biases favoring high-risk stocks, resulting in undervaluation of low-volatility stocks [9]. Conclusion - Each factor that consistently outperforms the market is influenced by both risk premiums and market mispricing, with understanding these dynamics aiding in the effectiveness of factor investing [10].
