According to Yicai, as of June 18th, Nvidia's market cap soared to $3.34 trillion, surpassing Microsoft to become the world's largest market cap company. Starting from last Thursday (June 20th), bears have been exerting pressure through futures, options and other derivative tools. Nvidia has fallen nearly 13% for three consecutive days, with a market value evaporating over $430 billion. Data analysis company Ortex Technologies statistics show that short-selling funds have gained nearly $500 million in profit in this round of selling. Valuation and shareholder shareholding reduction factors are believed to be the trigger for Nvidia's stock price fluctuations. Chuck Carlson, CEO of Horizon Investment Services, said that high market expectations make it easier to trigger panic when bad news hits. "For stocks like Nvidia, it's hard not to factor them into investment decisions because you have that chasing feeling, and valuation now looks relatively expensive," he said.
