The "Santa Claus rally" kept rolling on Wall Street this week, picking up momentum from an outstanding US GDP report that lifted the market to new records, SIA reports quoting the France 24.
The Dow and S&P 500 both closed the week out at fresh new peaks, with the blue-chip index registering its seventh straight gain in a surge that one analyst called a "humdinger."
For the week, the Dow Jones Industrial Average gained 248.91 points (1.40 percent) to 18,053.71.
The S&P 500 jumped 18.12 (0.88 percent) to 2,088.77, while the tech-rich Nasdaq Composite Index rose 41.48 (0.87 percent) to 4,806.86.
Hugh Johnson, head of Hugh Johnson Advisors, said he was heartened by gains in sectors linked to economic growth, like consumer discretionary spending and industrials. He noted that the small-cap Russell-2000 also reached a 52-week high Friday.
"You have all of the economically sensitive sectors sort of leading the parade recently," he said. "That tells us investors are becoming more optimistic about the economy and that's really good news.
"It's not only a humdinger of a rally, but it's also really positive if you look carefully at the market."
The highlight of the holiday-shortened week was Tuesday's report on third-quarter US gross domestic product, which came in at five percent, the best rate since 2003 and much better than the 3.9 percent previously estimated.
Spending for consumption rose 3.2 percent, the biggest jump since the end of 2013. Analysts also cited strong growth in defense spending and exports.
The US growth figures showed "an economy firing on all cylinders for the first time in many quarters," said FTN Financial chief economist Chris Low.
US stocks surged on the GDP report, with the Dow crossing 18,000 for the first time Tuesday and plowing to new peaks Wednesday and Friday. The Dow has notched 38 record highs in 2014, while the S&P 500 has registered 52 new peaks.
