* Federal Reserve sticks to stimulus in statement * Cyprus banking crisis a reminder of global risks * Homebuilders' stocks jump after Lennar earnings * Dow up 0.4 pct; S&P 500 up 0.7 pct; Nasdaq up 0.8 pct By Caroline Valetkevitch NEW YORK, March 20 (Reuters) - U.S. stocks climbed on Wednesday, with the S&P 500 snapping a three-day losing streak as the Federal Reserve reassured investors that it would keep supporting the economy. The housing sector's stocks ranked among the best performers after Lennar Corp reported a first-quarter profit well above analysts' expectations as lower interest rates and rising rents increased home sales. The Dow hit an intraday record high but fell short of closing at another record. The view that the Fed will keep interest rates at record lows for years has helped drive the rally in stocks this year, along with signs of a strengthening U.S. recovery. In its statement, the Fed said it would stick to its $85 billion monthly bond-buying stimulus, citing still high unemployment levels, but said it would take into account the possible risks of its policies. The statement, and comments by Fed Chairman Ben Bernanke, came as the market grapples with banking woes in Cyprus, the most recent flare-up in the euro-zone debt crisis. "It's amazing what a Fed on your side really brings for this market. It really can wipe out a lot of uncertainty," said Burt White, managing director and chief investment officer of LPL Financial in Boston. Cypriot leaders held crisis talks on Wednesday to avoid a financial meltdown a day after the country's parliament rejected a tax on bank deposits, which had been proposed over the weekend by European Union officials. Investors worry that a collapse of the banking system in Cyprus will tighten credit across Europe and become another hurdle in the region's bumpy road out of economic crisis. The Dow Jones industrial average gained 55.91 points, or 0.39 percent, to end at 14,511.73, after rising as high as 14,546.82, an intraday record. The Standard & Poor's 500 Index rose 10.37 points, or 0.67 percent, to 1,558.71. The Nasdaq Composite Index climbed 25.09 points, or 0.78 percent, to close at 3,254.19. The Dow is now up 10.7 percent for the year, while the S&P 500 is up 9.3 percent. Lennar's stock jumped 4.8 percent to end at $43.40, its highest closing level since June 2007. The PHLX housing sector index shot up 2.8 percent to 197.17, its highest close since July 2007. Shares of Adobe Systems Inc, maker of Photoshop and Acrobat software, also jumped, a day after the company raised its full-year adjusted earnings forecast. The stock gained 4.2 percent to $42.46. Among the day's decliners, shares of FedEx Corp lost 6.9 percent to $99.13, its largest daily percentage drop since September 2011, after it cut its full-year forecast and reported a 31 percent drop in quarterly profit due to restructuring costs and weakness in its air freight express business. The Dow Jones Transportation Average slipped 0.4 percent, weighed down by FedEx, one of its components. Volume was roughly 5.9 billion shares traded on the New York Stock Exchange, the Nasdaq and the NYSE MKT, compared with the 2012 average daily closing volume of about 6.45 billion. Advancers outpaced decliners on the NYSE by a ratio of about 3 to 1, while on the Nasdaq, 17 stocks rose for every seven that fell.
