Stocks futures edge lower after tech rallyU.S. stock futures opened slightly lower Monday evening after a whipsaw session in markets during the regular trading day, as investors appraised the next moves by the Federal Reserve and a fresh batch of quarterly earnings results. Contracts on the S&P 500 declined. During the regular trading day, technology stocks outperformed, leading the S&P 500 higher by 0.6%, and the Nasdaq up by 1.6%. And these moves in tech shares came even as the benchmark 10-year Treasury yield topped 3%, or its highest level since December 2018. In recent months, a rise in yields has coincided with a drop in tech shares, which are considered more vulnerable to higher rates that would weigh on growth stocks' valuations.And this week, investors are bracing for the Federal Reserve's latest monetary policy decision, which is set to include measures intended to accelerate the central bank's fight to bring down elevated inflation, even at the expense of some economic growth. Investors are looking for the Fed to raise rates by 50 basis points for the first time since 2000, and to officially announce the timing of the start of quantitative tightening, or the rolling of assets off the Fed's $9 trillion balance sheet.
