As expected, on October 15th, the A-share market saw a surge in trading volume at the end of the session.

At 2:40 p.m., the trading volume of the Huatai-PineBridge CSI 300 ETF suddenly increased significantly. By the close of trading, in just 20 minutes, the trading volume soared from over 8 billion yuan to 16.093 billion yuan, representing a 141% increase from the previous trading day. As of now, the scale of the Huatai-PineBridge CSI 300 ETF is 107.969 billion yuan, making it the largest exchange-traded fund (ETF) in the market.

At the same time, there was an increase in trading volume for the Huaxia SSE 50 ETF, which is also a common channel for large funds to enter the market before. Around 14:40, when the overall market index was correcting, the trading volume of the Huaxia SSE 50 ETF suddenly increased. By the close of trading, the trading volume of this ETF reached 5.401 billion yuan, a 119% increase from the previous trading day.

For two consecutive days, the trading volume at the close of the CSI 300 ETFs increased significantly, indicating a clear intention by large funds to support the market. In terms of selecting the ETFs for market stabilization, on October 14th they bought E Fund CSI 300 ETF, and on October 15th they chose Huatai-PineBridge CSI 300 ETF. At the same time, they also invested in products such as Huaxia Sci-Tech 50 ETF and Huaxia SSE 50 ETF.

Some market participants joked, 'Those who bought into it before, buy more now!' The leading companies with the broad-based ETF index have once again seen a surge in wealth.

Two broad-based ETF funds replicate the heavy trading volume at the end of the session again.

At the close of trading on October 16th, Huatai-PineBridge CSI 300 ETF led with a trading volume of 16.093 billion yuan, a significant increase of 141.45% from the previous day, making it the most dazzling "money absorber" of the day. This trading volume not only topped the list but also far exceeded that of the second-place Huaxia SSE Sci-Tech Innovation Board 50 ETF, which was 8.937 billion yuan. The clear trend of funds concentrating in the blue-chip sector of the market was evident.

The Huaxia SSE 50 ETF also performed outstandingly, with trading volume soaring from 2.466 billion yuan to 5.401 billion yuan, an increase of 118.99%, and a growth of 66.25% compared to 1.483 billion yuan on October 14th.

Looking at the details of the market, around 14:40 on October 15th, the price of Huatai-PineBridge CSI 300 ETF dropped to 4.201 yuan, a decrease of 0.97%. Subsequently, trading volume surged sharply, with large orders of 4.41 million yuan and 2.21 million yuan appearing in the market, causing the price to quickly rebound to around 4.236 yuan, with the decline narrowing to 0.14%. The trend of Huaxia SSE 50 ETF followed a similar pattern; at 14:40, the price touched 2.845 yuan, a decrease of 1.04%, after which large orders flooded in, driving trading volume to rise rapidly, and the ETF closed with only a 0.31% decline. The increased trading volume at the end of trading for both ETF ETFs occurred at the most pessimistic moments in the market, making their intention to support the market quite clear.

Since the end of September, over 140 billion yuan in funds have flowed in, making the broad-based ETF a "safe haven".

After a significant trading volume on October 15th, E Fund's CSI 300 ETF saw a single-day net inflow of over 18.8 billion yuan, E Fund's GEM ETF ETF had a net inflow of 5.53 billion yuan, and Huaxia Sci-Tech 50 ETF had a net inflow of 6.569 billion yuan.

Looking at the longer term, since September 28th, the stock ETF has seen a total net inflow of 140.7 billion yuan, of which 116.8 billion yuan was a net inflow into the broad-based index ETF.

This trend has accelerated since October. Looking at the six trading days from October 8th to 15th, the overall net capital inflow into the stock ETF exceeded 104 billion yuan. Among them, the net inflows into broad-based indices such as the CSI 300 Index, the Sci-Tech 50 Index, and the GEM Index were particularly significant. Observing the past five days, the capital inflow into the CSI 300 Index-tracking funds ETF exceeded 27.2 billion yuan, while that into the Sci-Tech 50 Index-tracking funds ETF exceeded 16.9 billion yuan.

Institutions say: It's not advisable to be overly pessimistic; the odds of success are higher when making arrangements at lower levels after a pullback.

Recently, valuations in global equity markets have been under pressure. The Federal Reserve's interest rate hikes, coupled with disruptions to the narrative surrounding the AI trend due to news regarding external optical modules, have led to increased volatility in the A-share market since the end of September. Many fund companies believe that positive factors in the current market are beginning to accumulate.

Looking back, the pressure from high congestion in the early stages is nearing its end, and sentiment indicators have further declined, approaching their lowest levels of the mid-period. With a new round of policies aimed at stabilizing growth gradually being implemented, the market is expected to receive support. There is no need to be overly pessimistic anymore, said Harvest Fund.

Firstly, in terms of policy, a new round of policies aimed at stabilizing growth, centered around mortgage interest subsidies for the real estate sector, were implemented before the festival, indicating the opening of a new window for stabilizing growth. It is expected that these policies will continue to have an effect. Secondly, regarding sentiment indicators, leveraged funds have been continuously withdrawing; in September, there was a outflow of over 50 billion yuan in financing. As of October 13th, the balance of margin trading had fallen below 2.55 trillion yuan, returning to the level seen at the beginning of April this year. On October 14th, market trading volume shrank to 1.42 trillion yuan, the lowest level since July 2025. Therefore, historically, after trading volumes shrink to their limit, it is generally not appropriate to remain overly pessimistic.

In addition, regarding the pullback in the technology growth sector, Harvest Fund stated that it was influenced by disruptions from messages from the US Federal Communications Commission ( FCC ) and fluctuations in peripheral tech stocks, but it did not represent a reversal in the industry trend. As the market continues to correct and "valuations + congestion" levels are reduced, performance-driven factors and domestic control over the industry are expected to act as a dual catalyst. Therefore, the long-term success rate of buying on dips after a pullback is often higher than chasing high prices during times of market excitement.
