In recent times, the A-share market has experienced increased volatility, while stock ETFs have shown a trend of "buying more as they fall". Multiple top fund companies have announced self purchase of their ETFs, and foreign institutions frequently appear on the list of newly established and listed ETF top ten holders. Data shows that since last week, as of October 30th, the net inflow of stock ETFs has been approximately 10 billion yuan. The unconventional 'buy as you fall' approach is not a simple investment impulse. Looking at the essence through phenomena, behind it lies investors' understanding of the characteristics of ETF products, their insight into the long-term improvement of the market, and their confidence in macroeconomic stability and recovery. The distinct characteristics of low cost, convenient trading, and transparent operation are one of the main reasons why ETFs have won the favor of funds. As an investment tool for tracking specific indices, ETFs purchase a basket of constituent stocks, which can effectively filter out significant fluctuations in individual stocks and diversify risks. Meanwhile, with the continuous emergence of innovative products, such as tracking the issuance and listing of ETFs such as the ESG Index, Carbon Neutrality 60 Index, and Science and Technology Innovation 100 Index, it not only selects the best from the best, but also expands the selection space, providing investors with a sharp tool for structured investment and attracting more investors to "place orders". The more the price drops, the more one needs to pay out. The seemingly reverse investment behavior is actually driven by rational investment philosophy. From the perspective of capital flow, broad base ETFs have become the "main force of attracting funds". Compared to industry themed ETFs, broad-based ETFs have a larger scale and a wider range of industries, making them more resilient to market adjustments. By configuring broad-based ETFs, it is possible to better avoid single industry risks and seize systematic investment opportunities. Some investors have shifted from being eager to frequently pursue market hotspots through industry themed ETFs to buying broad base ETFs, which is a more rational and stable manifestation of their investment style. The use of multiple funds through ETFs to "buy, buy," also reflects the gradual development of a long-term investment philosophy in A-shares. Although the volatility of A-shares has increased recently, some investors are not nervous about the prospects for China's economic development. Instead, they believe that the short-term decline in the market provides an opportunity for "bottom hunting", allowing them to buy undervalued assets at lower prices and obtain long-term, higher returns. This long-term optimism is not unfounded. The operation of the national economy in the third quarter shows that the overall recovery trend of China's economy is more obvious; The third quarter report of listed companies also revealed that multiple industries have ushered in performance turning points, which highlights the endogenous driving force of China's economic growth and the development prospects of high-quality listed companies. There is reason to believe that with the trend of "falling more and buying more", there will also be a trend of "buying more and rising more". Buying means a certain amount of funds entering the market, which helps to replenish market liquidity and enhance trading activity. Especially when there is a significant adjustment in the market, institutional investors can increase their holdings in ETFs with wider industry coverage, which can convey broader confidence and to some extent suppress market volatility. Market sentiment is warming up. On October 30th, after two months, the trading volume of the Shanghai and Shenzhen stock markets once again exceeded 1 trillion yuan. Believe in the power of belief. In recent years, policy measures to stabilize growth and market have been taken one after another: Huijin issued an additional 1 trillion yuan of treasury bond and successively increased its holdings in four major banks
