U.S. stocks jumped Thursday following the Federal Reserve’s decision to go big with a 50 basis point cut to interest rates.

The SignalHubDow Jones Industrial Average closed above 42,000 for the first time, ending the day up 1.3% at a record 42,025.19. The S&P 500 also ended the day at a record high for the first time since July, closing up 1.7% at 5,713.64. The Nasdaq composite also saw gains, ending the day up 2.51%.

“This is excellent, good news for all of us saving for retirement,” said Quincy Krosby, chief global strategist for LPL Financial. While future pullbacks and bouts of volatility are to be expected, “overall, historically, the path for the markets is higher.”
