(Reuters) – Wall Street’s main indexes fell more than 1% on Monday as investors worried about the economic fallout of a virus outbreak in China that has prompted the country to extend the Lunar New Year holidays and businesses to close some operations.

The benchmark S&P 500 was jolted off record highs last week as China locked down several cities and curbed travel, reminding investors of the deadly SARS virus that killed nearly 800 people in 2002-03 and cost the global economy billions.

Travel-related stocks, including airlines, casinos and hotels, were the worst-hit on Wall Street, while shares of tech heavyweights that enjoyed a strong rally recently dragged markets lower.

“There’s been an overabundance of bullishness … The market is overdue for a correction,” said Randy Frederick, vice president of trading and derivatives at Charles Schwab in Austin, Texas.

“If you’ve made a pretty good profit since October, it’s probably not a bad move at all to sell.”

Yum China Holdings Inc (YUMC.N) slid 4.4% after the company said it had temporarily closed some of its KFC and Pizza Hut stores in Wuhan.
