China's STAR 50 Surges 5% as Memory Chip Stocks Rally on Supercycle, IPO Momentum

China's tech-heavy STAR 50 Index recently surged by approximately 5%, led by a powerful rally in memory and semiconductor stocks.

This rally is fueled by a global memory "supercycle" with soaring prices, IPO plans from major domestic chipmakers like CXMT and YMTC, and renewed US export controls that bolster the domestic substitution narrative.

The convergence of these factors has created a focused investment theme on China's domestic semiconductor supply chain, attracting significant capital even as the broader stock market remains subdued.

China's tech-focused STAR 50 Index recently experienced a significant surge, primarily driven by a powerful rally in semiconductor and memory-related stocks.

The most significant tailwind is the ongoing global memory supercycle. Market intelligence firm TrendForce reported record-breaking price increases for memory chips, with DRAM and NAND contract prices soaring throughout the first half of 2026. This is largely due to immense demand from AI data centers, which is crowding out supply for other applications. This global supply squeeze has directly translated into higher profits and investor enthusiasm for memory producers worldwide, including those in China.

Second, this global trend is being amplified domestically by major capital market activities. China's leading memory manufacturers, CXMT and YMTC, are both moving towards public listings. CXMT's updated IPO prospectus revealed astounding growth, with projected first-half revenue soaring over 600% year-over-year. YMTC also began its official IPO process. These listings signal a new era of investment in domestic production capacity, creating a ripple effect of expected orders for local equipment, materials, and software suppliers.

The third crucial factor is the geopolitical landscape. The United States has been advancing legislation like the MATCH Act to tighten export controls on semiconductor manufacturing equipment. News of these restrictions, along with enforcement actions against smuggling, constantly reminds the market of supply chain vulnerabilities. This geopolitical pressure strengthens the import substitution narrative, making domestic suppliers appear not just as a choice, but a strategic necessity for China's tech independence.

In conclusion, the recent rally isn't a random event but the result of three powerful forces converging. The global memory supercycle provides the profit momentum, the landmark IPOs of CXMT and YMTC provide the domestic investment catalyst, and U.S. policy provides the long-term strategic urgency. This explains why capital is flowing so aggressively into the semiconductor sector, even while the broader Chinese stock market has been relatively weak, creating a highly concentrated and powerful market trend.
