Nvidia Corp.'s shares experienced a significant decline, dropping over 10% during trading on April 16, 2025. The stock, which is among the world's largest companies, saw its value decrease by a tenth in a single day, contributing to a broader market cap loss of over $1 trillion for the S&P 500. This sharp drop in Nvidia's stock price was preceded by declines in premarket trading, with the stock down 5% initially, then nearly 6%, and finally -6.8% before the market opened. The company has lost billions in market cap within eight hours and more than a quarter of its value over the past six months. The decline in Nvidia's shares was part of a wider downturn affecting other semiconductor giants, with AMD also seeing a similar decrease in its stock value of more than 10%.
