Nvidia Corp.’s results would make most companies jealous, but after a stock price gain of more than 800% in two years, great is no longer good enough for Wall Street.

The main sticking point was the turnover forecast for the current quarter, which exceeded analyst estimates by just $400 million. It marked the second straight period that Nvidia’s quarterly revenue projections fell short of average analyst expectations by $1 billion or more, suggesting that the hypergrowth that fueled the rally is quickly fading.
