Core Insights - The article discusses the mathematical logic behind dividend indices, highlighting their ability to implement a "buy low, sell high" strategy through dividend yield adjustments as stock prices fluctuate [1][2]. Group 1: Mechanism of "Buy Low, Sell High" - Valuation is a core indicator for determining price levels in investments, with dividend yield serving as a filter for high-valuation stocks in dividend indices [2]. - Data from the past five years shows that newly included companies in the CSI Dividend Index have significantly higher P/E ratios compared to those removed, demonstrating the "buy low, sell high" characteristic of the indices [2][6]. - The sensitivity of the "sell high" mechanism is evident, as 15% of companies removed from the dividend index had price increases exceeding 30% in the previous year, compared to only 6% in the CSI 300 [6]. Group 2: Dividend Yield Dynamics - The largest weight stock in the CSI Dividend Index, Ningbo Huaxiang, has a dividend yield of only 1.6%, which is below the index average of 4%, raising questions about the core logic of dividend strategies [8]. - This situation illustrates the effectiveness of the dividend mechanism, as the stock's price surged over 200% while maintaining stable dividends, leading to a lower yield [8]. - The annual rebalancing of the index automatically removes stocks with reduced yields due to price increases, replacing them with new stocks that have higher yields and more attractive valuations [8]. Group 3: Industry Composition and Resilience - There is a common misconception that the dividend index is limited to specific sectors like banking and coal; however, the essence of the index is its focus on high dividend yields rather than fixed industries [9][12]. - The weight of the banking sector in the index has changed significantly over the years, currently at 23%, while coal has increased to 17%, showcasing the dynamic nature of the index [10]. - The dividend index operates on a principle of "ironclad dividends, fluid industries," maintaining a focus on high dividend standards regardless of market trends, which enhances its resilience during market fluctuations [12]. Group 4: Investment Strategy - The "buy low, sell high" strategy of the dividend index is not about timing the market but is achieved through strict dividend yield selection rules, ensuring a disciplined investment approach [13]. - The index does not attempt to predict market peaks or troughs but reallocates funds to the most cost-effective high dividend assets through annual rebalancing [13]. - The investment wisdom lies in constructing a simple, executable system that aligns with long-term trends, allowing investors to benefit from consistent dividend income and capital gains without extensive analysis [13].
