Hong Kong’s semiconductor sector saw sharp declines on May 18, led by an over 8% drop in Innoscience, revealing cracks in the "China is back" narrative as intense internal competition weighs on technology shares.

Hong Kong-listed semiconductor stocks fell sharply in afternoon trade on May 18, with Innoscience (英诺赛科) plunging more than 8 percent, challenging the broader market narrative of a tech-led rebound in China. The selloff, which also saw Hua Hong Semiconductor fall over 1 percent, comes amid what analysts call "involution"—fierce domestic competition that is pressuring margins even in sectors targeted for growth by Beijing.
"China may be back, but policy- and news-driven volatility has not disappeared," Manishi Raychaudhuri, founder and CEO of Emmer Capital Partners, wrote in a recent commentary for Reuters. "Investors thus need to proceed with caution – and not skimp on the due diligence."
The sector's weakness was specific, with GigaDevice Innovation's morning gains narrowing to less than 6 percent by the close. The move contrasted with a strong year-to-date performance for some, like Huahong Semiconductor, which was up a striking 56 percent through mid-May, according to Reuters data. However, the broader technology services sector, including giants like Tencent and Baidu, had dropped 17 percent over the same period, reflecting investor anxiety over high development costs and intense competition.
The divergence underscores the growing challenge for investors in China's tech space. While Beijing's push for self-sufficiency has funneled capital into the industry, it has also created a crowded field where companies are locked in a fierce battle for market share, often at the expense of profitability. This dynamic, starkly visible in the electric vehicle price wars, is now creating a clear divide between winners and losers in the capital-intensive semiconductor industry.
Beijing's efforts to upgrade the country's economy through investment in advanced technology have shown clear results, with high-tech manufacturing helping drive a better-than-expected 5.0 percent GDP growth in the first quarter. This has translated into outperformance for Hong Kong-listed industrials and technology sectors this year.
However, performance within those sectors diverges sharply. In electric vehicles, Geely and BYD shares have risen this year on the back of strong exports, while smaller rivals like XPeng have fallen more than 20 percent. A similar story is playing out in chips, where industry leader SMIC was down over 5 percent for the year through mid-May on concerns about heavy capital expenditures, even as its smaller rival Huahong rallied.
The pressure on Chinese chipmakers contrasts with the AI-driven boom elsewhere. Singapore, for example, saw its electronics exports surge 66.7 percent in April, led by an 82.7 percent jump in integrated circuits, according to data from Enterprise Singapore. Economists attribute this to robust global demand for AI-related infrastructure.
This trend has benefited companies like Applied Materials, which rallied strongly after positioning itself as a direct beneficiary of accelerating AI investment. The divergence highlights the difficult landscape for Chinese firms, which must navigate not only intense domestic competition but also geopolitical tensions and US trade restrictions that can limit their access to global markets and technologies.
