NEW YORK (CNNMoney.com) -- Shares of UPS surged Thursday after the world's largest delivery company reported sales and earnings that beat analysts' expectations and raised its outlook for the rest of the year.
The rally came after UPS said second-quarter earnings surged 90% on strong sales in the United States and abroad. Big Brown also said it expects earnings to grow this year despite the "slow pace of the U.S. recovery."
Investors cheered the results because UPS, which delivers consumer products around the world, is seen as a proxy for overall economic activity. Stocks were up more than 2% with about two hours left in the session.
"The market is adjusting to the idea that companies can still perform in a slow growth environment," said James Ragan, an analyst who covers UPS at Crowell, Weedon & Co.
While the results benefited from an easy comparison to last year, Ragan said investors were encouraged to see that sales at UPS continued to grow despite signs the economic recovery has hit a soft patch.
"I think people are feeling today that there's still room for revenue growth," he said.
UPS said revenue in the quarter jumped nearly 13% to $12.2 billion.
The Atlanta-based company said it earned $845 million, or 84 cents a share, in the second quarter. That's up from $445 million, or 44 cents a share, a year earlier.
Analysts were expecting earnings of 77 cents per share, according to consensus estimates from Thomson Financial.
