Indexes rallied Thursday, with tech stocks leading the Nasdaq to rise 2.5% as investors continued to digest Wednesday's jumbo rate cut from the Fed.

Stocks were choppy in the lead-up to today's Federal Reserve policy announcement. While the main indexes made a confident move higher after the central bank cut rates by a half-percentage point, a late-day burst of selling pressure sent them into the red at the close.

Markets in Europe and Asia shot higher on Thursday after the Federal Reserve kicked off its efforts to prevent a recession in the U.S. with a bigger-than-usual cut to interest rates. U.S. futures were higher after a lackluster response on Wall Street to the Fed's move the day before.
