NEW YORK, March 19 (Reuters) - U.S. stock index futures were down slightly on Thursday implying a lower opening for stocks after the Federal Reserve cut economic growth and inflation projections and indicated it was in no rush to hike interest rates.
U.S. stocks had ended up higher on Wednesday as investors, who had sold equities ahead of the meeting, were relieved by Fed Chair Janet Yellen's dovish outlook.
But investors will now seek signs of improvements in the U.S. economy after Yellen "removed the word 'patient' but underscored the need for patience", said Peter Kenny, chief market strategist at Clearpool Group in New York.
"Yesterday's rally has all the appearances of being a one-day pop," he said.
"She's basically told markets it's later rather than sooner. That provides some buoyancy for the markets, but it's going to take significantly more than that for the markets to move higher. Better economic data would be a very important component."

Dow Jones industrial average e-mini futures fell 45 points and Nasdaq 100 e-mini futures lost 4 points.
