NEW YORK (Reuters) - Wall Street roared back to life on Tuesday, rebounding from the brink of bear market confirmation as bargain-hunting and hopes of government stimulus calmed investors’ fears surrounding the coronavirus and growing signs of imminent recession.

All three major indexes jumped nearly 5% the day after equities markets suffered their biggest one-day losses since the 2008 financial crisis.

Still, the S&P 500 and the Nasdaq ended the session about 15% below the record closing highs reached on Feb. 19. Sinking beyond the 20% mark would confirm a bear market.

U.S. President Donald Trump said he will take “major steps” to allay market fears by asking Congress for a fiscal stimulus package to include a payroll tax cut, among other measures.

“Coming off yesterday, you’ve got short-term bargain-hunters coupled with potential fiscal stimulus hopes,” said Chuck Carlson, chief executive officer at Horizon Investment Services in Hammond, Indiana.

“It may be the biggest benefit is not actually what’s getting done - it’s that there appears to be a plan,” Carlson added. “There does appear to be a willingness to do something, and that’s probably what’s helping the market.”

Market participants largely expect the U.S. Federal Reserve to cut interest rates for the second time this month at the conclusion of next week’s two-day monetary policy meeting.

Outside the United States, major world economies took steps to cushion the effects of the fast spreading COVID-19.

Global markets have been rattled in recent weeks by the rapidly spreading coronavirus, which has caused widespread supply chain disruption, hobbled the travel industry and prompted drastic containment measures in Italy and elsewhere.

Market uncertainties surrounding COVID-19 were exacerbated over the weekend as Saudi Arabia and Russia scrapped their supply pact and pledged to increase crude oil production.

But oil prices rebounded from Monday's largest percentage drop since the 1991 Gulf War, with front-month Brent crude LCOc1 rising 10.0% after Russia indicated it was open to talks with OPEC.
