Apple AAPL.O, Microsoft MSFT.O and Meta Platforms META.O gained between 0.7% and 2.6%. By Shristi Achar A and Sruthi Shankar June 15 (Reuters) - The main U.S. stock indexes touched multi-month highs on Thursday as Treasury yields slid after a slew of economic data pointed to easing price pressures, offsetting concerns about the Federal Reserve sticking to a hawkish monetary policy. The Fed left rates unchanged at the 5%-5.25% range on Wednesday, but indicated they could rise by at least half a percentage point this year as inflation remains stubbornly persistent and the U.S. economy stays resilient.
