The YieldMax NVDA Option Income Strategy ETF (NVDY) surged 7.76% to close at $20.68 on January 28, as Nvidia shares 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 cost-effective AI model, which had initially triggered a 17% plunge in Nvidia's stock. Analysts now suggest that concerns over DeepSeek's influence may be exaggerated, particularly in the U.S. market, where Nvidia's leadership in AI and autonomous applications remains strong. The open-source nature of DeepSeek's model could also stimulate further innovation, potentially benefiting Nvidia in the long run. Additionally, a significant dip-buying rush occurred, with investors pouring $1 billion into the GraniteShares 2x Long NVDA Daily ETF and $1.3 billion into the Direxion Daily Semiconductors Bull 3x Shares, reflecting renewed confidence in Nvidia's prospects.
