U.S. Markets Close Higher, Red Robbin Serves Disappointing Earnings

U.S. stocks ended higher on Thursday on light volume as investors held out hope the crisis in Ukraine will not escalate. Perrigo (PRGO), a maker of generic over-the-counter drugs was the S&P 500's biggest gainer. Boeing (BA) and Proctor and Gamble (PG) were the blue chip's biggest advancers. Tesla (TSLA) shares managed to close at a fourth straight record. The electric-car maker added to gains after Credit Suisse (CS) became the latest Wall Street firm to issue a positive report on the company. But, a disappointing report on earnings from Red Robin Gourmet Burgers (RRGB) pushed shares down more than 18%. On Friday, as earnings season winds down, investors will get quarterly reports from Estee Lauder (EL). TheStreet's Susannah Lee reports from New York.
