The S&P 500 and the Nasdaq cratered into a bear market on Thursday (local time) as a shock move by President Donald Trump to suspend travel from Europe rattled investors already shaken by fears of a global recession on the back of a coronavirus pandemic.
Trading on Wall Street was halted minutes after the opening bell as the S&P 500 slid 7 percent and triggered a 15-minute cutout. The indexes are now more than 24 percent below their intraday record highs hit in February.

American Airlines and United Airlines plummeted over 13 percent.
"It's not just the fear of the economy going weak, but basically being on the brink of shutting down," said Dennis Dick, proprietary trader at Bright Trading LLC in Las Vegas.
"It's mass selling across the board (and) we are pricing in a potential to go into another financial crisis."
Investors were also unnerved by the absence of targeted stimulus measures and the lack of details on a public health response after Trump made no mention of widely expected payroll tax cuts.
Online travel agents Expedia Group Inc and Booking Holdings Inc, as well as hotel operator Marriott International and casino operator Wynn Resorts shed more than 10 percent.
Wall Street's fear gauge jumped about 15 points to its highest since November 2008 at 68.76, as the death toll from the virus rose to over 4,600 worldwide, according to a Reuters tally.

The FTSE index has shed about 28 percent since its January peak, as the heavy blow from the outbreak shook investor confidence despite the Bank of England's emergency move to cut interest rates by 50 basis points and the UK government's 30 billion-pound ($39 billion) stimulus plan.
"Each time that you've seen stimulus announced, any rebound has been very short-lived," said Joshua Mahony, senior market analyst at IG. "That's because you can't cure someone of a virus and the need to quarantine by giving them cheaper interest rates, or quantitative easing."
Oil majors BP Plc and Royal Dutch Shell Plc slipped between 3 percent and 5 percent, as oil prices took another blow from the dramatic moves by Trump.
