The Dow and S&P 500 finished at records Tuesday after technology stocks shook off a two-day slump to lead the market higher ahead of a much-anticipated Federal Reserve decision.

At the closing bell, the Dow Jones Industrial Average was at 21,328.47, up 0.4 percent.

The S&P 500 rose 0.5 percent to end at 2,440.35, narrowly topping its prior record, while the tech-rich Nasdaq Composite Index jumped 0.7 percent 6,220.37.
