Order Reprints Text size Stocks rallied, pushing the three major U.S. indexes to closing records. The rally “can go on for a while,” one observer said. Stocks across the board rose sharply Thursday, and all three major U.S. indexes closed at records. Investors are growing so confident, they’re willing to pay what is now a hefty price to own stocks. The S&P 500 rose 55.65 points, or 1.48%, to end at 3,803., and the Nasdaq Composite rose 326.69 points, or 2.56%, to close at 13,067.48. The biggest gainer on the S&P 500 was DXC Technology (ticker: DXC), which surged 9.3% on reports the IT-services giant has received takeover interest.
