The YieldMax NVDA Option Income Strategy ETF (NVDY) closed at $23.70 on December 27, down 1.58%, as Nvidia shares fell 2.10% to $136.99 amid a broader tech sell-off. Nvidia's decline was influenced by competitive pressures and geopolitical tensions, particularly concerning U.S.-China relations. A Chinese startup, DeepSeek, unveiled an AI model using Nvidia's GPUs at a fraction of the cost typically incurred by Western companies, raising concerns about potential U.S. export restrictions. Additionally, the PHLX Semiconductor Index (SOX) dropped 1.01%, reflecting broader market weakness. The tech-heavy Nasdaq fell 2.2%, with Nvidia and Tesla leading the decline, as investors shifted away from tech stocks that had previously driven market gains.
