July 29 (Reuters) - U.S. stocks were little changed on Friday after Alphabet and Amazon's strong results lifted technology stocks, helping offset losses in energy shares.
Investor sentiment was also dented by a slower-than-expected growth in U.S. gross domestic product.
Exxon shares fell 4 percent and Chevron 2 percent as a slump in oil prices hurt their quarterly results.
