U.S. Stock Futures Waver as China Slowdown and Rate Worries Weigh

U.S. stock futures wavered Thursday, with markets at risk of a third straight day of declines as investors fretted over further signs of an economic slowdown in China and the prospect of the Federal Reserve keeping interest rates higher for longer. S&P 500 futures fell 0.3% with contracts tracking the tech-heavy Nasdaq down 0.6%. China worries weighed on sentiment already dampened by increasing expectations among investors that the Fed will remain more hawkish on monetary policy.
