General Motors' stock (NYSE: GM) has risen by 39% from $42 to $58 since the end of 2020. In comparison, the broader S&P500 rose by 16% in the same period. Trefis analysis of GM's valuation is $70, implying that the stock seems cheap at its current price. The auto industry is being hit by the semi-conductor shortage currently, which converts to lower sales volume for the companies. In the recently completed Q3 2021 the company delivered 446,997 vehicles in the U.S., down 218,195 units from a year ago as a result of semiconductor supply chain disruptions and historically low inventories. The company expects the fourth quarter to be smooth as they are restarting production at key crossover and car plants, and anticipate the semiconductor supply disruptions to improve.
