According to The Kobeissi Letter, Nvidia ($NVDA) disclosed 13 days ago that the US government imposed restrictions on its H20 chip exports to China. In response, Huawei is now preparing to test its new AI chip, Ascend 910D, specifically designed to replace Nvidia's H20 for the Chinese market. This rapid development highlights significant shifts in AI hardware supply chains, directly impacting trading strategies for both Nvidia and Chinese tech equities. Traders should closely monitor the competitive positioning of Nvidia and Huawei as the release and adoption of the Ascend 910D could alter demand dynamics for AI chips in China and potentially affect NVDA stock performance (Source: The Kobeissi Letter, April 28, 2025).
