U.S. stocks finished nicely higher to trim Monday's tumble as concerns appeared to ease regarding real estate debt concerns in China, which was the major contributor to the early-week selloff. The recovery accelerated following the Fed's highly-anticipated monetary policy decision, which delivered an unchanged policy stance, while holding off on naming a definitive start date for the tapering of asset purchases. The markets shrugged off the continued political stalemate regarding raising the debt ceiling with current and former Treasury Secretaries offering warnings if a deal is not reached. Treasuries were mixed, with the yield curve flattening following the Fed's decision and the U.S. dollar moved higher in choppy trading. Gold fell and crude oil prices gained solid ground as oil inventories continued to be drawn down at a faster-than-expected pace. In economic news, existing home sales fell to snap a two-month winning streak, and mortgage applications rose as rates remained stable for a fifth-straight week. FedEx Corporation missed earnings estimates and lowered its guidance due to increased costs associated with the labor shortage, Adobe fell despite topping earnings estimates, and Stitch Fix rallied after posting an unexpected profit. Europe rebounded for a second day, and Asia finished mixed as China returned to action and showed some resiliency in the face of the real estate debt crisis.
