The ETF Opportunities Trust T-Rex 2X Long NVIDIA Daily Target ETF (NVDX) closed down 5.73% at $9.71 on February 3, as Nvidia Corporation's stock fell 2.24% to $117.38 amid heightened market volatility and trade tensions. Nvidia's decline was exacerbated by recent revelations from Chinese startup DeepSeek, which claimed to have trained its AI model for under $6 million, significantly less than the billions spent by U.S. tech giants. This announcement has raised concerns about potential shifts in customer preferences towards more cost-effective AI chips, impacting Nvidia's market position. Additionally, discussions between Nvidia CEO Jensen Huang and U.S. President Donald Trump regarding potential AI chip export regulations have added to the uncertainty, contributing to the stock's downward pressure. The broader semiconductor sector, represented by the SOX index, also saw a decline of 1.82%, reflecting the broader market sentiment.
