July 29 (Reuters) - The S&P 500 and the Dow indexes scaled record highs on Thursday as a slate of strong corporate earnings reports and data showing a pickup in U.S. economic growth reinforced confidence ina post-pandemic recovery. Ford Motor Co (F.N) jumped 4.0% to hit a more than three-week high as it lifted its profit forecast for the year, while KFC-owner Yum Brands Inc (YUM.N) rose 5.2% after beating expectations for quarterly sales. read more Overall, of the 195 companies in the S&P 500 that have reported second-quarter earnings so far, nearly 91% have beaten estimates, according to Refinitiv, although investors have begun to book profits across equities after solid stock market gains this year. "Even if earnings are strong, you can"t look at the environment of the past year and say this is the fundamental trend of these businesses," said Mike O"Rourke, chief market strategist at JonesTrading. "So for most investors, they have to decide: do you want to chase at these higher multiples or do you want to take a step back and let the business settle in? I would take a step back." Still, economically sensitive S&P indexes including financials (.SPSY), miners (.SPLRCM) and energy (.SPNY) jumped more than 1%, a day after the Federal Reserve said it was not yet time to start withdrawing its massive pandemic-era monetary stimulus. read more The real-estate sector (.SPLRCR) - generally considered a defensive play - hit a record high as the Fed also said there was "very little support" for cutting the $40 billion in monthly purchases of mortgage-backed securities "earlier" than the $80 billion in Treasuries.

Tesla Inc (TSLA.O) jumped 4.8%, tracking its best day in more than a month, and was the biggest boost to the S&P 500 (.SPX).

With rising inflation, and concerns that higher prices would not be as transient as expected, focus on Friday will be on the June reading of the personal consumption expenditures price index - the Fed"s main inflation measure.
