China’s equity markets concluded the month of May with a striking display of sectoral divergence, as the technology-focused STAR 50 Index rallied over 11% to reach levels not seen since mid-2020. This surge highlights a growing bifurcation in investor sentiment, where strategic 'hard tech' sectors are increasingly decoupled from broader macroeconomic volatility affecting the traditional Shanghai and Shenzhen benchmarks.
The rally was primarily fueled by a massive influx of capital into the semiconductor and artificial intelligence hardware supply chains. Key industry players, including SMIC, Cambricon, and Will Semiconductor, saw their stock prices hit record highs during the month, buoyed by Beijing’s intensified push for technological self-reliance and the global demand for AI infrastructure. Ancillary sectors such as Printed Circuit Boards (PCB) and Co-Packaged Optics (CPO) also witnessed explosive growth, with some firms recording gains exceeding 100%.
Despite the tech-led optimism, the broader market experienced significant turbulence. The Shanghai Composite Index followed a 'rise then fall' trajectory throughout May, ultimately ending on a cautious note as the month closed with a high-open-low-close pattern. While the ChiNext Index managed to hold the 4,000-point psychological level, the volatility in non-tech sectors suggests that investors remain wary of the broader recovery’s sustainability and real estate headwinds.
Global institutional interest appears to be stabilizing, with reports indicating that foreign investors now hold over 4 trillion RMB in A-share circulating market value. Major investment banks, including Morgan Stanley, have notably shifted their gaze toward China’s high-end manufacturing and 'hard tech' assets. This influx of professional capital is narrowing the focus of the market toward structural opportunities rather than a broad-based index recovery.
