SanDisk rose approximately 26%, Micron Technology over 18%, SK Hynix over 17%, Western Digital over 15%, AMD and Credo over 13%, and Intel over 11%.

In Asia-Pacific markets, South Korea's KOSPI index rose over 16%, with the "duo of memory giants," SK Hynix and Samsung Electronics, skyrocketing.

On July 31, the three major A-share indices opened higher, and the chip sector staged a violent rebound.

As of 9:33, the Pud Xian Science and Technology Innovation Board Chip Design ETF (589250) rose 8.58%; among sample stocks, Puran Shares rose 17.81%, Jwelltech rose 15.57%, Biwin Storage rose 12.85%, Shengke Communications-U rose 11.33%, and Montage Technology rose 11.3%.

Data from Wind shows that as of the previous trading day, the Pud Xian Science and Technology Innovation Board Chip Design ETF (589250) had a net inflow of 31.6848 million yuan over the past month.

In terms of news, recently, the Chairman of SK Hynix increased his holdings by purchasing 3,620 ordinary shares of SK Hynix. The stated reason was strong confidence in the long-term value of the semiconductor industry, along with the view that SK Hynix's recent sharp stock price decline resulted in severely undervalued valuations.

According to reports, TSMC is developing advanced packaging technology to benchmark against Intel's EMIB, aiming to cope with increasingly fierce industry competition.

Traditional 2.5D packaging (such as TSMC's CoWoS) requires an entire large-size silicon interposer, whereas Intel's EMIB technology embeds microscopic "silicon bridges" only between chips to achieve high-speed interconnection. This architecture not only has lower costs and higher yields but also supports larger-scale packaging dimensions. With these advantages, EMIB can perfectly meet the needs of AI chips integrating massive computing units and memory, thus attracting significant attention from the industry.

A research report from CITIC Securities points out that although the tech sector has seen significant volatility recently, this does not change the positive trend in fundamentals for the second half of the year. The trend towards domestic autonomous controllability and closed loops is becoming clearer. The upward trends in semiconductor equipment, Fab, and domestic computing power autonomy are all clear. Meanwhile, under the global AI trend, power-related sectors, PCBs, and storage remain robust, spreading to consumer electronics. Coupled with strong earnings from electronics companies in the Q2 reports, the YoY and QoQ trends are clearly accelerating, leading to optimism about the sector's future performance.

The Pud Xian Science and Technology Innovation Board Chip Design ETF (589250) closely tracks the SSE Science and Technology Innovation Board Chip Design Theme Index (950162), highly focusing on 50 listed chip design companies on the STAR Market, where digital chip design accounts for nearly 80% of the weight. It avoids segments such as semiconductor materials, equipment, manufacturing, and packaging/testing. Within the chip sector, it has a lower valuation compared to the semiconductor materials index, better aligning with industrial development trends.

In terms of elasticity, the SSE Science and Technology Innovation Board Chip Design Theme Index only includes chip design companies on the STAR Market, with component stocks having daily price limits of ±20%, offering greater elasticity and stronger offensive potential.

In terms of growth, the Pud Xian Science and Technology Innovation Board Chip Design ETF (589250) tracks the SSE Science and Technology Innovation Board Chip Design Theme Index. Between January 5, 2024, and March 30, 2026, the target index accumulated a rise of 141.86%, making it the top-performing chip industry theme index in terms of gains, surpassing the STAR Market Chips (133.60%), CSI All Share Semiconductors (97.77%), and Semiconductor Materials & Equipment (98.39%).
