Nvidia Earnings Impact: Why Lenovo, Not SMIC, is Hong Kong’s True Proxy

Hong Kong's stock market closed higher on Wednesday, with the Hang Seng Index up about 0.6% and the Hang Seng TECH Index opening roughly 0.75% higher earlier in the session, positioning local traders ahead of Nvidia's fiscal second-quarter earnings, due after Wall Street's close tonight. Nvidia has guided to roughly $91 billion in revenue, and Wall Street consensus sits a shade above that.

The assumption among a lot of Hong Kong retail traders is that Semiconductor Manufacturing International Corp, the mainland's largest chipmaker, is the local Nvidia proxy — the stock that gaps up or down at Thursday's open depending on what Jensen Huang says about China tonight. That assumption doesn't hold up well.

SMIC is trading on a different story

SMIC jumped 10% in a single session last Friday, its biggest blue-chip move on the Hang Seng that day. The trigger wasn't Nvidia. It was DeepSeek releasing a new model built to run on domestic Chinese chips rather than Nvidia hardware, a shift brokerages said would accelerate demand for China's homegrown compute stack.

That's the pattern with SMIC this year. Beijing has been pushing data centers to source a majority of their AI chips domestically, and SMIC's role as the country's designated foundry for that push — supplying capacity to Huawei's Ascend line and other domestic AI chip designers — is what moves the stock, not Nvidia's numbers.

It also matters that Nvidia doesn't guide to China revenue at all right now. Its most advanced Blackwell chips remain barred from the Chinese market outright, and the lower-spec H200 is trickling in only under a capped, license-by-license arrangement — Nvidia's own finance chief has said the company has yet to book meaningful revenue from those sales. There's no "China guidance" for Huang to hand Hong Kong tonight, because the company has deliberately left China out of the number entirely.

The cleaner read-through is Lenovo

If there's a genuine Hong Kong-listed proxy for Nvidia's own data center business, it's Lenovo Group, a Hang Seng Index and Hang Seng TECH constituent whose Infrastructure Solutions unit builds AI servers around Nvidia GPUs. That division has been Lenovo's fastest-growing business, with an order backlog reported at $54 billion as of its own August earnings, and the stock has already run hard this year on AI-server demand.

Lenovo won't move on new information from Nvidia's print the way a stock reporting its own numbers would — it already reported this quarter. But because its hardware business rises and falls with actual GPU shipment volumes and Nvidia's data-center commentary, it's a more honest bellwether than a foundry whose fortunes increasingly run on Beijing's substitution policy instead.

The broader and more reliable pattern is the Hang Seng TECH Index moving as a basket. Hong Kong's tech-heavy names have tracked Nvidia's own share price almost mechanically this week — the index fell nearly 4% Monday on pre-earnings jitters and clawed most of it back Tuesday and Wednesday as Nvidia stabilized, even without any China- or Hong Kong-specific news driving it. That's largely a sentiment and hedging-flow effect, not a fundamentals one.

There's precedent for how sharp that swing can be. After an underwhelming Nvidia print earlier this year, the Hang Seng Index fell 1.4% and the Hang Seng TECH Index dropped 2.9% the same session, dragging down Alibaba, Tencent, Meituan and JD.com in the process.

For Thursday's open, the more useful signal isn't whether Huang says anything specific about China — he likely won't — but whether Nvidia's data-center revenue and shipment commentary beats or undershoots that roughly $91 billion guide. A strong beat with confident Blackwell shipment language is what would move Lenovo and the Hang Seng TECH basket. SMIC, for now, is watching a different chip war entirely.
