Core Viewpoint - The article discusses the discrepancies in the price-to-earnings (P/E) ratios of the China Securities Dividend Index across different platforms, attributing these differences to the weighting methods used in calculating the index [2][4][14]. Group 1: Index Weighting Methods - Different platforms use varying methods for index weighting, leading to different P/E ratios for the same index [2][4]. - Most platforms rely on financial terminal data, which typically uses market capitalization for weighting, meaning larger companies have a higher influence on the index [4]. - In contrast, the Dividend Index uses a dividend yield weighting method, giving more weight to stocks with higher dividend yields [5]. Group 2: Impact of Bank Stocks - The primary difference in P/E ratios arises from the weighting of bank stocks within the indices [6][8]. - For instance, the Industrial and Commercial Bank of China (ICBC) has a weight of approximately 1.2%-1.3% in the Dividend Index based on dividend yield, while its market capitalization accounts for about 12% of the total index [7][8]. - Consequently, when using market capitalization for calculations, the P/E ratio is skewed towards the lower valuation of bank stocks, resulting in a P/E ratio of around 7 times [8][14]. Group 3: Actual Valuation Insights - The actual P/E ratio of the Dividend Index is more accurately reflected at over 9 times when considering the actual holdings rather than market capitalization [8][14]. - The article emphasizes that the historical data and percentiles derived from a market cap-weighted approach can be misleading [14]. - It suggests that for more accurate valuation, calculations should be based on the actual stock holdings within the index [15][16].
