Core Viewpoint - The article discusses the current market conditions, emphasizing the importance of understanding index valuation percentiles and the associated risks when making investment decisions. Market Overview - The major indices, such as the Shanghai and Shenzhen 300, have shown little fluctuation, while small-cap stocks have slightly declined [2][4]. - Value and dividend styles have seen minor increases, whereas growth styles have experienced slight declines [3][4]. - After a significant drop in early April, global markets have rebounded over the following weeks, but have recently entered a period of sideways movement [5][6]. Index Valuation Percentiles - The article highlights that percentile rankings can be a useful reference for current valuations in historical contexts [7][8]. - A 30% percentile indicates that 30% of historical valuations were lower than the current one [9]. Risks Associated with Percentile Valuation 1. Short Historical Data: Relying on a short time frame for index data can lead to misleading conclusions. Historical data should ideally encompass multiple market cycles [12][13]. - Solution: Use longer historical indices of similar styles for reference [14][15][16]. 2. Changes in Index Rules: Modifications in index selection criteria can alter valuation metrics, making historical comparisons less relevant [18][19][20]. - Solution: Recalculate historical valuations based on new rules [21]. 3. Different Valuation Weighting Methods: Variations in how indices calculate valuations can lead to discrepancies in percentiles. For example, the dividend index's valuation can differ significantly based on whether it is market-cap weighted or dividend-yield weighted [22][23][24][28]. - Solution: Calculate valuations based on the actual stocks held in the index [29]. 4. Economic Downturns: During economic slowdowns, declining earnings can artificially inflate price-to-earnings ratios, skewing percentile rankings [5][30]. - Solution: Use stable financial metrics for valuation when earnings are volatile [30][31]. New Features and Tools - A new feature in the "Today Stars" mini-program has been launched, allowing users to access ETF valuation tables and identify undervalued ETFs [32][35]. - The program provides real-time data on ETF valuations, including premium/discount rates and historical valuation data [35]. Investor Engagement - The article encourages investors to share their experiences and thoughts, particularly regarding the three-year anniversary of the investment strategy, highlighting the importance of perseverance during market downturns [40][41].
