Financial markets exercised their own form of social distancing Thursday as they ignored friendly intervention and plunged deeply into bear territory amid coronavirus fears, notching their worst day of trading since the 1987 crash.

Neither an automatic timeout in trading, nor a $1.5-trillion Federal Reserve pledge to sop up the bond market, nor a series of clarifications and reassurances from the Trump administration could stem a selling contagion. The market listened, then spun on its heels and sold. The Dow Jones industrial average fell 2,352 points, down about 10%, with the S&P 500 and Nasdaq trimming 9.5% and 9.4%, respectively.

The pain was widespread. Travel plummeted over government restrictions and concerns about containment of the virus. Energy was particularly hard hit as an oil price war coupled with an anticipated fall in demand weighed on investors. Technology firms faltered, with Amazon dropping nearly 8% and Apple falling 9.9% over questions about its supply chain and sales in China. The consumer durables sector notched one of the market's few gains, up more than 6%, as buyers hoard supplies.

Investors were not convinced by President Trump's Wednesday-night speech, nor his Thursday reassurance that the markets would bounce back "very big at the right time." Within hours, they sent a message back that Thursday was not that time.

Some took the coronavirus panic as validation of an ongoing hunch that the market was overvalued, said René Nourse, a CNBC commentator and founder of Urban Wealth Management, an El Segundo financial advisory firm. "When the coronavirus happened it kicked the door down."

With the market in chaos, talk in Washington turned to remedies. Few of them promise help in the short term.

Trump reiterated his proposal to suspend the payroll (Social Security) tax even as key members of Congress remained skeptical about its multi-billion-dollar cost and scant prospects of turning things around quickly.

For an employee making $25,000 a year, the deduction hiatus would leave an extra $60 in take-home pay every two weeks.

That is no solace to those in the gig economy who are not covered by the payroll tax or those outside the labor force, including the elderly. Any temporary tax savings is easily erased by furloughs and cuts in hours tied to economic disruptions, which now include a drop in demand for goods and services atop the early disruptions in supply from countries such as China.

New victims include the ushers, ticket takers, janitors and food service workers in Southern California sports venues, including Dodger Stadium, Angel Stadium, Staples Center, Banc of California Stadium, Dignity Health Sports Park and Honda Center. Major League Baseball pushed back the season opener by at least two weeks, while the National Basketball Assn., the National Hockey League and Major League Soccer suspended their games indefinitely.
