NEW YORK, Feb 26 (Reuters) - An index of global equity markets eased after hitting a fresh record high on Thursday as concerns about lofty valuations of leading technology companies weighed on markets after artificial intelligence chipmaker Nvidia NVDA.O reported strong quarterly results.

Shares on Wall Street and in Europe traded down as investors digested another blowout quarter from Nvidia, the world's most valuable company, but worried about its market value even as it forecast that first-quarter revenue would come in at a whopping $78 billion.

On Wall Street, technology and communication services were the biggest losers, with Nvidia's shares down 4%. The Dow Jones Industrial Average .DJI rose 0.11%, the S&P 500 .SPX fell 0.70%, and the Nasdaq Composite .IXIC fell 1.37%.

"People are getting concerned about lofty valuations even though when you look at a company like Nvidia, the estimates, cash flow, and everything else are dramatically higher," said Thomas Plumb, chief executive and portfolio manager at Plumb Funds in Madison, Wisconsin.

"But I think the sentiment will eventually match up with the realities," said Plumb, who has Nvidia as his largest investment holding.

In Europe, the broad STOXX 600 .STOXX index fell 0.11%. MSCI's All Share Index .MIWD00000PUS was down 0.30% after rising to a record high of 1,063.86.
