Nvidia lost 4 trillion yuan in market value over nine trading days, and its stock closed just above $210. Jensen Huang chose to respond on Wednesday, from 5 to 7 p.m. Beijing time, at GTC Berlin. The European session was still underway, while U.S. markets had yet to open.

The complication was that Meta was set to report earnings after the close that evening. The founder would get his point across first, and a few hours later the market would weigh Meta’s capital spending against it—with no time in between to absorb the news. Both events fell on the same trading day, putting pressure on both the person speaking and the people listening.

Berlin was a cleverly chosen venue, too: during European trading hours, still several hours before the U.S. market opened. That gave the remarks time to circulate overseas first. The real test would be the market’s reaction at the U.S. open, and whether it lined up with the figures Meta reported after the close.
