In a recent four-day period, NVIDIA's stock has seen a strong rebound, with the cumulative gain reaching nearly 17%, which has also boosted overall market performance. According to the latest data, NVIDIA's market cap has increased by more than $400 billion during this period. During this upward trend, NVIDIA contributed approximately 22% to the S&P 500 Index. Ivana Drevska, founder and Chief Investment Officer at Spear Invest, commented that NVIDIA's quarterly earnings report brought numerous positive signals. Although the impact of carry trades was significant, positive factors are no longer the key determinant of stock prices. With the easing of technical pressure and markets returning to fundamentals, this is the main reason for the substantial increase in stock prices. Meanwhile, option trading activity reflects different expectations among investors regarding NVIDIA's stock performance: the cost of hedging against a 10% decline in the stock price over the next 60 days has reached its highest level since May 2023, compared to contracts that profit from a 10% rise in the stock price. This indicates that some investors have concerns about further declines in NVIDIA's stock.
