* Federal Reserve sticks to stimulus in statement * Cyprus banking crisis a reminder of global risks * Homebuilders' stocks jump after Lennar earnings * Dow up 0.5 pct; S&P 500 up 0.8 pct; Nasdaq up 0.8 pct By Caroline Valetkevitch NEW YORK, March 20 (Reuters) - U.S. stocks added to gains after the Federal Reserve said it was pressing forward with aggressive efforts to stimulate the economy. In their statement, Fed officials said unemployment remains too high and noted "restrictive" fiscal policy. The Dow hit a record intraday high before the statement, which was expected to leave current policies in place. Federal Reserve Chairman Ben Bernanke is expected to host a a news conference around 2:30 p.m. "I wasn't expecting a lot from the Fed, in terms of the statement or actions. We've had a volatile week. The Fed was not going to want to rock the boat much," said Paul Zemsky, head of asset allocation at ING Investment Management in New York. "It would be too destabilizing in a time we've just had a destabilizing European effect." Cypriot leaders held crisis talks on Wednesday to avoid a financial meltdown after the country's parliament rejected a tax on bank deposits proposed over the weekend by European Union officials. Investors fear 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.
