China’s financial markets witnessed a historic day on July 9, as the tech-heavy STAR 50 index skyrocketed by 8.41%, signaling a massive shift in investor sentiment toward domestic high-tech industries. This explosive growth was anchored by the semiconductor sector, which saw a collective rally that pushed the industry’s most prominent giants to unprecedented heights. The broader market also reflected this optimism, with the Shanghai Composite and Shenzhen Component indices gaining 1.65% and 3.07% respectively.
At the heart of this rally was Semiconductor Manufacturing International Corp (SMIC), China’s leading chipmaker, which saw its share price surge over 13% to reach a new all-time high. The fervor extended beyond manufacturing into the entire value chain, including advanced packaging and semiconductor materials. Local firms such as JCET and Shanghai Helin hit their maximum daily price limits, reflecting a desperate scramble by investors to secure positions in what is being viewed as a national strategic priority.
The scale of the market activity was staggering, with total turnover across the Shanghai and Shenzhen exchanges reaching 2.91 trillion RMB, a significant increase from the previous trading day. This massive influx of liquidity suggests that both institutional and retail investors are moving away from defensive positions and pouring capital into 'hard tech' sectors. Despite the broader rally, the market remained bifurcated, with nearly 2,900 stocks ending the day lower as capital rotated out of sectors like lithium mining and traditional energy.
This dramatic surge comes at a time when China is doubling down on its push for technological self-reliance amid ongoing global trade tensions. The concentration of capital into the STAR Market—often referred to as China’s answer to the NASDAQ—demonstrates a growing confidence in the domestic supply chain's ability to withstand external pressures. While volatility remains a concern for many, the sheer volume of trading suggests that for now, the market has found its new engine of growth in the silicon-based economy.
