Stocks erased nearly all of their losses for the year after investors interpreted comments from the Federal Reserve to mean that an interest rate hike is less likely.
The S&P 500 and the Nasdaq turned positive for the year, erasing all of last month's selloff, while Dow Jones Industrials is still down slightly for the year.
Stocks were powered higher by strength in brokerages and banks, which saw their best performance since July of last year. Financials was the best performing S&P 500 sector, surging more than 2%. Buying was across the board with all of the sectors trading firmly in positive territory. The Dow utilities hit historic highs.

"While the Fed didn't really change its bias, it did look a little less hawkish than in January," Barry Ritholtz, chief market strategist at Ritholtz Research & Analytics, told CNBC.com. "People were looking to see a cut sooner rather than later. We didn't get that but we did get language that dropped the threat of future tightening."
As expected, the Fed kept the overnight lending rate at 5.25% and said it remains more concerned about the risk of inflation than slowing economic growth. Stocks and bonds rallied after the Fed omitted a reference to future tightening, signaling to many investors that the central bank has softened its stance.
"It's very clear that this was the most dovish statement we've had in some time," said Jim Cramer, host of CNBC's Mad Money. "The bond and stock markets are saying, 'ease.' I'm calling for a May cut."
"On balance I think there was more good than bad in the statement," Arthur Hogan, managing director at Jefferies, told CNBC.com. "The Fed sort of leaned in the direction that inflation will ease moving forward and that was reassuring. There was enough balance in the statement to indicate that the Fed is as likely to ease as tighten."
Treasury notes rallied, sending yields lower. The Treasury yield curve turned positive after the Fed decision.
Some analysts, however, urged caution.
"I think the response to the Fed statement has been overdone," Al Goldman, chief market strategist at A.G. Edwards, told CNBC.com. "They pointed out that inflation is still a problem. I would preach a little caution short-term, although long-term, I'm still looking for an interest rate cut sometime this summer."
