The Dow rose nearly 1,300 points Monday, its biggest percentage gain since 2009.

After some major bloodletting last week, the Dow Jones Industrial Average had its biggest single-day percentage gain since 2009 on Monday, rising nearly 1,300 points or more than 5%.

The S&P 500 and Nasdaq similarly rallied Monday, up by 4.6% and 4.49%, respectively, by the time trading closed.

The volatility left some analysts and experts scratching their heads, coming on the heels of major losses last week when the Dow suffered its worst week since the financial crash of 2008 amid uncertainty over the novel coronavirus.
