U.S. Treasury yields edged lower on Friday, helping boost major growth stocks, with Tesla TSLA.O and Meta Platforms leading gains, up about 1.6% each. By Shristi Achar A and Amruta Khandekar Sept 8 (Reuters) - The S&P 500 and Nasdaq rose on Friday as megacaps including Apple and Tesla gained ahead of a fresh inflation reading next week that will provide further clues on the U.S. interest rate trajectory.
