Monster gains notwithstanding, Wall Street is still bullish on the semiconductor company. Of the 65 analysts who follow Nvidia, 92% give the stock a buy rating and the remaining 8% give the stock a hold rating. Moreover, Nvidia's median price target of $150 per share implies 14% upside from its current share price of $132.

The surprise increase was the first since the electric-car maker’s earnings began to slide earlier this year as it turned to deep price cuts and other sales promotions to stimulate sales.
