U.S. stock futures declined after quarterly reports from Apple and Amazon.com showed that supply-chain problems and tight labor markets are hitting even some of the biggest corporate winners of the pandemic.
Futures for the S&P 500 fell 0.5% Friday, indicating that the broad market index would pare recent gains after the New York opening bell.
