Stocks jump 7% despite bleak coronavirus projections

The S&P 500 closed up 7% on Monday, while the Dow rose more than 1,500 points.

Why it matters: The huge market surge comes amid rare optimistic signs that the spread of the coronavirus may be slowing in parts of the country, including New York. But government officials say this will be a difficult week, while economists — including former Fed chair Janet Yellen today — warn that the pandemic could have a catastrophic impact on the global economy.
