July 24 (Reuters) - U.S. stock indexes looked set to open little changed on Monday ahead of earnings reports from a clutch of tech heavyweights, including Google parent Alphabet, this week and a two-day Federal Reserve meeting that is set to begin on Tuesday.
Alphabet will report results after market close. Amazon and Facebook are due to report results later this week.
Tech continues to be the best performing S&P sector this year, despite concerns about stretched valuations.

The Federal Reserve will meet on Tuesday and Wednesday. Although there are no expectations of an interest rate hike, the market will await the Fed's statement for clues regarding the path of future rate hikes.
