NEW YORK — The Dow Jones Industrial Average surged to its best day since 1933 as Congress and the White House neared a deal on Tuesday to inject nearly $2 trillion of aid into an economy ravaged by the coronavirus.

The Dow burst 11.4% higher, while the more closely followed S&P 500 index leapt 9.4% as a wave of buying around the world interrupted what has been a brutal month of nearly nonstop selling. Despite the gains, investors were far from saying markets have hit bottom. Rallies nearly as big as this have punctuated the last few weeks, and none lasted more than a day.

Both Democrats and Republicans said Tuesday they’re close to agreeing on a massive economic rescue package, which will include payments to U.S. households and aid for small businesses and the travel industry, among other things. A Senate vote appeared likely on Wednesday, with a House vote to follow.

Investors have been waiting in frustration for such aid, particularly as the Federal Reserve has done nearly all it can to sustain markets, including its latest round of extraordinary aid launched Monday.

The Dow rose 2,112.98 points, its biggest point gain in history, to 20,704.91. The S&P 500, which is much more important to most 401(k) accounts, rose 209.93, or 9.4%, to 2,447.33 for its third-biggest percentage gain since World War II. The Nasdaq composite jumped 557.18 points, or 8.1%, to 7,417.86.

The buying circled the world. South Korean stocks surged 8.6%, Germany’s market jumped 11% and Treasury yields rose in a sign that investors are feeling less fearful.

“It’s still early days, of course — perhaps investors can start to envisage life beyond the coronavirus,” said Craig Erlam, senior market analyst at OANDA Europe. “That could make stocks look a little more attractive, although anyone jumping back in now will need to have nerves of steel.”
