The A-shares experienced a typical rally and pullback in the early trading session, but the performance of the STAR Market was notably different—rising over 1% on a single-sided upward trend, leading all four major indices. The driving force behind this is quite clear: collective strength from blue-chip stocks.

In terms of sector popularity, brain-computer interfaces and commercial aerospace are the two main themes attracting the most capital. Brain-computer interfaces (medical device sector) and commercial aerospace (military industry theme) have become the most certain upward directions for A-shares at present. Other military-related sectors with gains exceeding 3% include controllable nuclear fusion, military equipment, domestically produced aircraft carriers, large aircraft, and aviation engines. These sectors are not only short-term hotspots but also have a solid foundation for continued strength over the next year.

The STAR 50 Index once surged to 2.7%, although it has not yet broken last year's high, the daily K-line has closed positively for four consecutive trading days, indicating a very clear upward trend. More interestingly, all the leading stocks with a market capitalization exceeding 200 billion—such as SMIC, Haiguang Information, Cambrian, Moore Threads, Muxi Integrated Circuits, and Huahong Semiconductor—are gaining strength, with Haiguang Information even hitting the daily limit up. Cambrian and Moore Threads have both increased by over 5%. What does this indicate? The core investment focus remains on large-cap blue-chip stocks; only with these leaders steadily rising can a true breakthrough rally be possible in the future.

From an investment strategy perspective, it is not advisable to chase stocks that have already surged significantly in hot sectors—risk is too high. Instead, blue-chip targets that are still adjusting, with relatively low valuations, steady performance, and not yet fully appreciated, are more worthy of long-term holdings as core positions.

The situation of the Shanghai Composite Index is somewhat more complex. Although it opened lower and then moved higher in the early session, with a trading volume reaching 740 billion yuan, it is expected to break 1 trillion yuan for the whole day. However, the collective weakness of the financial sector has exerted a noticeable drag on the index—securities, banking, and insurance sectors all closed in the red, with securities and insurance falling more than 1%. This is the main reason for the index's underperformance.

In the short term, the Shanghai Composite is likely to continue its upward and downward fluctuations in the afternoon, with increased volatility risk. However, the daily trading volume of over 1 trillion yuan provides sufficient liquidity support, and the index remains in a strong oscillation range. After sufficient adjustment, it still has the strength to challenge 4100 points.
