The ETF Opportunities Trust T-Rex 2X Long NVIDIA Daily Target ETF (NVDX) closed up 17.25% at $11.96 on January 28, as Nvidia's stock rebounded 8.27% to $128.21 following a historic sell-off. Nvidia's recovery was fueled by a reassessment of the impact of DeepSeek's AI model, which initially caused a 17% drop in Nvidia's stock. Analysts now suggest that fears of DeepSeek's model disrupting Nvidia's market position may be exaggerated, particularly in the U.S. market. Nvidia's statement viewing DeepSeek's innovation as a positive development further bolstered investor confidence. The company's emphasis on Test Time Scaling, which requires significant GPU resources, suggests continued demand for Nvidia's products. Retail investors also played a role, buying the dip at record levels, as reported by Vanda Research.
