NEW YORK, Nov 28 (Reuters) - U.S. stocks were mostly higher in thin trade on Friday, as investors eyed retail sales on the first day of the shopping season after the Thanksgiving Day holiday, to gauge the extent of weakening consumer demand.
European and Asian shares were also higher, despite the attacks in Mumbai, India, while U.S. Treasury debt prices and the U.S. dollar both gained as investors continued to look for safe-havens as global economic growth slows.
"It's a light volume day so you're going to see some choppy trading, with so many people out," said Robert Finkel, consumer trader at Stifel Nicolaus in Baltimore of the U.S. stock market.
"I'm watching how things go from a retail standpoint today - we've heard a lot of speculation about how bad it's going to be, now we'll get some proper feedback."
The U.S. holiday weekend will test the strength of consumer sentiment, a main driver of the U.S. economy, as the country faces its worst financial crisis since the Great Depression. If the U.S. consumer fails to buy, companies across the globe can expect to see fewer exports and profits.
