The S&P 500 and the Nasdaq were set to open higher on Thursday, buoyed by tech-related stocks, a day after the Federal Reserve reiterated its pledge to remain ultra-dovish until an economic recovery is more secure. Apple Inc, Microsoft Corp Facebook Inc and Amazon.com Inc rose between 0.8% and 1% in premarket trading. High-growth tech stocks have recovered in recent sessions as U.S. 10-year bond yields backed off from their 14-month highs.
