Feb 27 (Reuters) - U.S. stocks were little changed on Tuesday, with losses in media stocks weighing on major indexes, while investors braced for Federal Reserve Chairman Jerome Powell's first congressional testimony.
Powell hinted in prepared remarks that the central bank would stick to its current path of gradual rate hikes despite the added stimulus of tax cuts and government spending.
Fed policymakers anticipate three rate increases this year, and Powell gave no indication that the pace needs to quicken even as the "tailwinds" of government stimulus and a stronger world economy propel the U.S. recovery.
"Pretty much the market is going to be fluttering back and forth in both directions based on things he says today, so it doesn't surprise me too much," said Randy Frederick, vice president of trading and derivatives for Charles Schwab in Austin, Texas.
"It's his first speech and the market is already in a higher volatility phase."
Powell's testimony comes at a sensitive time for the markets, which have swayed wildly in recent weeks on inflation fears.

U.S. cable giant Comcast offered to buy Sky for $31 billion in an unsolicited approach, taking on Rupert Murdoch's Fox and Bob Iger's Walt Disney in the battle for Europe's biggest pay-TV group.
Comcast fell 5.2 percent, while Walt Disney dropped 3.1 percent and Twenty-First Century Fox 1.9 percent.
The stocks were the biggest drags on the S&P consumer discretionary index, which fell 0.57 percent.
