Nvidia is Wall Street's 2nd-most valuable company. How it keeps beating expectations, by the numbers

Nvidia has once again turned out quarterly results that easily exceeded Wall Street’s forecasts. The company has seen soaring demand for its semiconductors, which are used to power artificial intelligence applications. Revenue more than doubled in the latest quarter from the same period a year earlier, Nvidia said Wednesday. The company expects further revenue growth in the current quarter that ends in October. Investors will be watching to see if demand for the company’s products can maintain its red-hot pace.
