CATL Margins Squeeze as STAR 50 Drops 40% on AI Profit Doubts

Chinese technology shares have shed more than 40% of their value since peaking in July. The drop centers on the STAR 50 Index, which tracks 50 major firms on Shanghai's technology-focused market. Investors are now questioning whether the country's artificial intelligence boom can produce earnings high enough to support current price tags.

Battery manufacturer CATL faces particular scrutiny. The company lost 37% of its value from the start of the year through late October. In its third-quarter report, CATL recorded revenue growth of roughly 59%. However, net profit rose by only about 15%. This gap between top-line expansion and bottom-line growth illustrates the pressure on margins across the sector.

Benjamin Cavender of China Market Research Group noted that the initial sell-off looked like standard profit-taking after a strong run. He said the situation has shifted to a critical review of whether actual earnings justify the excitement around AI. Tai Hui, Asia-Pacific chief market strategist at JPMorgan Asset Management, added that investors are waiting to see how major tech groups convert heavy spending into real income. He pointed out that several recent AI initial public offerings saw strong early demand before interest faded.

The economic headwinds extend beyond the tech sector. China's prolonged property downturn has reduced household confidence. Weak consumer spending continues to strain the advertising and e-commerce operations of major internet platforms. Vey-Sern Ling, a senior equity advisor at Union Bancaire Privée, warned that rising AI investment could further pressure near-term earnings. He stated that long-term monetization remains uncertain.

Ling observed that Chinese tech valuations have reached multi-year lows. This positioning may limit further downside, but he noted that clear catalysts for upside remain elusive. Cavender identified the divergence between growth and profitability as CATL's central issue. Competition, shifting product mixes, and changes in taxes and rebates are eroding margins despite the company's dominant global position.

Brendan Ahern, chief investment officer at KraneShares, noted that not all market segments face identical pressures. Companies on Shanghai's STAR Board are benefiting from semiconductor spending by Chinese and American tech giants. In contrast, Hong Kong-listed stocks are more exposed to sluggish domestic consumption due to their heavier weighting in consumer-facing platforms.

Hui described the property downturn as a fundamental obstacle to market recovery. Households are increasingly holding savings in cash rather than equities. Despite this, he sees limited downside for broader Chinese benchmarks. He cited relatively undemanding valuations and light positioning among international investors as supporting factors.

Jason Hsu, chairman and chief investment officer at Rayliant Global Advisors, suggested the sell-off may offer an opportunity. He said the weakness in Chinese tech has deepened alongside declines in U.S. equities as skepticism over AI returns grows. He argued that a recovery in American technology shares could support Chinese stocks. Cavender cautioned that cheaper valuations alone may not be enough. A lasting rebound would require stabilizing earnings, clearer returns on AI spending, and stronger domestic demand.
