Nvidia Corp. has experienced a significant sell-off over the past month, with its shares dropping 9.8% since its fourth quarter earnings results on Feb. 26 and 24% from its mid-January 52-week high. The stock has fallen below key technical indicators such as the 50-day, 100-day, and 200-day moving averages. Market technicians are closely monitoring the 200-day moving average, a long-term momentum indicator, which Nvidia surpassed in January for the first time in over two years. This development has led to concerns about further declines in the stock's value. The sell-off has been part of a broader market uncertainty affecting major tech stocks, with Nvidia contributing to more than 30% of the Nasdaq's decline this year. Analysts are watching Nvidia's stock closely, with some suggesting potential support levels between $110 and $103, and further support around $90. Nvidia's latest earnings report indicated expected gross profit margins of 70.6% to 71% in the first quarter as it contends with the production ramp-up of its new Blackwell chip. The company's CEO, Jensen Huang, emphasized the high demand for Nvidia's Blackwell systems and teased new powerful chips to be unveiled at the company's GTC conference on March 17. In contrast, Broadcom Inc. reported strong earnings after the market close, causing its shares to rise by $30 in after-hours trading. This positive report has sparked hope that it might help stabilize the market sentiment, particularly in the semiconductor sector, amid concerns about AI investments by hyperscalers such as Amazon.
