The chart highlights the most significant single-day stock declines, with Nvidia experiencing eight out of the ten largest drops. The most substantial decline occurred on January 27, 2025, when Nvidia's stock plummeted by $560 billion. This dramatic fall was triggered by the release of a powerful AI model by a Chinese startup named DeepSeek. The data reveals a pattern where Nvidia's stock has been particularly volatile, with multiple significant declines occurring in 2024. Notably, Amazon and Meta also appear on the list, with Amazon experiencing a $206 billion drop on April 29, 2022, and Meta seeing a $251 billion decline on February 3, 2022. The concentration of Nvidia's declines in 2024 suggests a period of heightened instability for the company, possibly due to competitive pressures or market dynamics. The presence of other tech giants like Amazon and Meta indicates that the tech sector, in general, has faced substantial challenges, leading to these massive single-day losses. This pattern underscores the volatility and risk associated with tech stocks, particularly in the face of disruptive technological advancements and competitive threats.
