U.S. stocks climbed Thursday after market superstar Nvidia and another round of companies said they’re making even fatter profits than expected. The S&P 500 pulled 0.5% higher after flipping between gains and losses several times during the day.

Expectations were sky-high and some fatigue may have crept in over Nvidia’s rocket-like trajectory but make no mistake: this was a remarkable quarter, burnished by fantastic execution and a sound plan.

Goldman Sachs said Nvidia has another trick up its sleeve to drive its stock price higher going forward: a massive stock buyback program.
