Core Viewpoint - The article discusses various strategies for enhancing investment returns, focusing on fundamental enhancement, quantitative enhancement, and new share subscription methods. Group 1: Fundamental Enhancement - Fundamental enhancement involves allocating more to high-performing sectors such as consumer and healthcare, as well as to companies with high Return on Equity (ROE) and strong long-term profitability [4]. - It emphasizes the importance of investing in leading companies within industries that exhibit a leader effect, which can provide better returns [4]. - This strategy is typically employed by actively managed funds with strong individual stock research capabilities, and the findings can also be applied to index-enhanced funds [4][5]. Group 2: Quantitative Enhancement - Quantitative enhancement utilizes various quantitative factors to build models that capture investment opportunities, requiring strong capabilities from the fund's quantitative team [6]. - Common quantitative factors include valuation factors, fundamental factors, price-related factors, and sentiment factors, which can be used individually or in combination [6]. - A successful quantitative model typically includes factors that identify high-quality stocks and those that are undervalued, allowing for strategic buying during low valuation periods [7]. Group 3: New Share Subscription - In addition to fundamental and quantitative enhancements, funds can also enhance returns through new share subscriptions, which are typically accessible to funds with a scale of over 200 million [7].
