Morning Bid: China markets latest to get AI fever

Asian markets exhibited divergence, with Japan's Nikkei falling 2% as AI-focused stocks like Advantest and SoftBank Group saw profit-taking, down 9.1% and 6% respectively, potentially influenced by reports of Chinese AI firms opting for domestic chip solutions like Huawei. In contrast, Hong Kong's market surged, driven by Alibaba's near 19% jump on cloud business optimism and broader Chinese blue chips gaining over 10% last month, supported by domestic liquidity and Beijing's push for indigenous AI chip development. Concurrently, legal challenges to US tariff policies create ongoing uncertainty, with a potential Supreme Court ruling carrying significant implications for trade negotiations and the possible repayment of over $100 billion in collected tariffs.

Analysis

Asian equity markets demonstrated a significant divergence at the start of September, reflecting a complex interplay of profit-taking, shifting technology supply chains, and macroeconomic policy uncertainty. Japan's Nikkei index declined by 2%, heavily influenced by a sell-off in AI-related stocks; chip group Advantest plummeted 9.1% and SoftBank Group fell 6%. This downturn appears to be a reaction to both recent strong performance, with Advantest having gained nearly 50% in the prior three months, and reports of Chinese AI firm DeepSeek opting for Huawei chips, signaling a potential competitive threat to the dominant Nvidia ecosystem. In stark contrast, Hong Kong's market surged, driven by a nearly 19% single-day jump in Alibaba shares on optimism surrounding its cloud business. This move is contextualized by a broader rally in Chinese blue chips, which climbed over 10% last month, supported by ample domestic liquidity and a strategic push from Beijing for indigenous AI chip development. Concurrently, a significant macro risk is developing in the U.S., where legal challenges to existing tariff policies are creating uncertainty. A potential Supreme Court ruling in October could not only diminish U.S. trade negotiation leverage but also force the Treasury to repay over $100 billion in collected tariffs, introducing fiscal strain and market volatility.

Key Decisions for Investors

• Investors should evaluate the diverging performance between Chinese technology firms like Alibaba, which are benefiting from domestic liquidity and strategic initiatives, and global AI-related stocks such as Advantest that face new competitive risks from China's push for technological self-sufficiency.
• The 9.1% drop in Advantest on news of a Chinese firm adopting Huawei chips serves as a signal to reassess exposure to companies in the established AI supply chain, as the rise of viable domestic Chinese alternatives could disrupt valuations and market share.
• It is prudent to monitor developments around the U.S. tariff legal challenges, as a Supreme Court decision against the tariffs in October could trigger significant market volatility, impact trade-sensitive sectors, and create fiscal headwinds for the U.S. government.
• Given Alibaba's 19% surge, its largest since early 2022, a deeper analysis of the fundamental drivers behind the renewed optimism in its cloud business is warranted to determine if this represents a sustainable re-rating.
