On October 27, A-shares declined broadly on shrinking volume, with market risk appetite contracting notably. Against this backdrop, broad-based ETFs continued to attract capital favor, becoming one of the efficient tools for capital deployment amid a volatile market.
Wind data shows that as of October 23, ETFs tracking the CSI 300 Index had recorded six consecutive weeks of weekly net capital inflows since September 14. Over the past two weeks (10/12-10/23), alongside the market's rapid adjustment, the overall inflow amount into these products also jumped in tandem, with combined inflows reaching approximately 103.693 billion yuan, accounting for over eighty percent of the total inflows over those six weeks (117.829 billion yuan). Among them, the popular product Huatai-PineBridge CSI 300 ETF (510300) became a key focus for capital deployment. Wind data shows that as of October 27, its average daily turnover since the start of October reached 7.389 billion yuan, a marked increase from the year-to-date average daily level of 5.978 billion yuan. On October 23, 22, and 16, volume surged significantly to 15.4 billion yuan, 14.6 billion yuan, and 16.1 billion yuan respectively, reflecting relatively active market trading.
It is understood that the CSI 300 Index is composed of 300 industry stocks with large market capitalization and strong liquidity from the Shanghai and Shenzhen markets, designed to represent the overall performance of the A-share large-cap market. From an industry structure perspective, the index's weighting is concentrated in sectors such as electronics, banking, non-bank financials, telecommunications, and power equipment. With constituent stocks accounting for less than 6% of the total number of A-share companies, it covers 48% of total A-share market capitalization and contributes over 78% of listed companies' net profits, featuring a relatively balanced perspective and prominent earnings resilience. It may serve as a mainstream vehicle for accessing core A-share assets amid market volatility.

On October 27, Huatai-PineBridge CSI 300 ETF (510300) released its 2026 third-quarter report, in which the fund manager noted that looking ahead to the fourth quarter of 2026, the core contradiction in A-share asset trends may focus on the pace of market risk appetite recovery and the verification of policy effects. From a supporting factors perspective, the policy side remains proactive, with key tasks for the opening year of the "15th Five-Year Plan" continuing to advance. After third-quarter adjustments, overall A-share valuations have fallen back to a historically reasonable and low range, and compared horizontally with major global capital markets, they may offer certain valuation cost-effectiveness and investment appeal. Meanwhile, confidence signals are also being released from CSI 300 constituent stocks. Recently, multiple weighted listed companies in the index have conveyed fundamental information to the market through buybacks, operational briefings, and earnings disclosures. A leading A-share battery company implemented A-share buybacks on October 21 and 22 consecutively, repurchasing approximately 5.7596 million shares in total at a cost of about 1.299 billion yuan, with all repurchased shares planned for cancellation. Additionally, on October 28, a total of 870 listed companies in the A-share market disclosed their 2026 third-quarter reports, of which 649 were profitable, representing a profitability ratio of 75%, which is expected to solidify the fundamental foundation for market recovery. After earlier adjustments, the valuation of the CSI 300 Index has gradually fallen or retreated to a configuration range with certain appeal. Wind data shows that as of October 27, the index's latest price-to-earnings ratio reached 12.82 times, positioned at a moderate percentile range of 51.85% over the past 10 years. At the same time, the equity-bond yield spread of the CSI 300 Index reached 6.17%, at the 84.56% percentile level over the past decade, and also above the historical mean plus one standard deviation. (Investing in government bonds and stock assets involves different risk-return characteristics; investors should fully consider risks when investing. Wind data shows that as of 26/10/27, the 10-year government bond yield was 1.63%.)
