Better-than-expected profit outlooks from drug makers Pfizer and Eli Lilly bolstered Wall Street, while a rise in US home prices also underpinned optimism that the economic recovery is kicking into gear.
Shares of Pfizer gained, last up 3.1 per cent, after the company predicted 2013 profit that surpassed expectations. So did Eli Lilly, boosting its shares 3.8 per cent.
Of the 174 companies in the S&P 500 that have reported earnings this season, 68.4 per cent have been above analyst expectations, according to Thomson Reuters data.
There was bright news on US house prices, which posted their biggest annual gain since 2006. The S&P/Case Shiller composite index of 20 metropolitan areas increased 0.6 per cent in November on a seasonally adjusted basis, and jumped 5.5 per cent year over year, the most since August 2006.
"What we're seeing is really a gradual improvement in the overall economy," Anthony Chan, chief economist for Chase Private Client in New York, told Reuters.
