The ETF Opportunities Trust T-Rex 2X Long NVIDIA Daily Target ETF (NVDX) closed down 8.03% at $11.00 on January 29, as Nvidia's stock faced significant pressure, dropping 2.56% to $125.69. The decline in Nvidia's stock was primarily driven by concerns over potential new restrictions on its chip sales to China, as the Trump administration considers expanding existing curbs to include Nvidia's H20 model. This development comes amid heightened scrutiny of China's AI advancements, particularly following the release of DeepSeek's AI model, which has been accused of leveraging U.S. technology. Nvidia's exposure to China, which accounted for over 15% of its revenue in the last quarter, is a critical factor as further restrictions could impact its revenue streams. Additionally, the market reacted to the broader tech sector's volatility, with the Nasdaq 100 weakening as traders reassessed the risks associated with U.S.-China tensions and AI market dynamics.
