Nvidia Wednesday morning recovered from a significant fall as the latest challenges to the AI chip leader drove the stock 15% below its all-time high of 152.89 at Tuesday's low. Nvidia fell below it for the first time since Sept. 12 on Tuesday last week — ending a nearly three-month-long stint above the benchmark. In its Securities and Exchange Commission filing earlier this year, Nvidia had disclosed that one customer accounted for 13% of its fiscal first-quarter revenue.
