NEW YORK (REUTERS) - A set of strong earnings from companies, including Caterpillar and McDonald's, lifted the Dow and drove the S&P 500 to a record high, but the tech-heavy Nasdaq was dragged lower by losses in Google parent Alphabet Inc.
Shares of McDonald's surged 5 per cent after the fast-food giant posted the biggest rise in sales at established restaurants globally in five years.
Caterpillar's shares rose 4.1 per cent after the company reported quarterly results that smashed expectations and raised its full-year outlook for the second time this year.
However, Alphabet fell 2.6 per cent, after the tech giant warned that expenses would remain high as more searches shift to mobile devices.
