Dow surges to its best day since 1933

— 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 on 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.

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.

The market has seen rebounds like this before, only for them to wash out immediately. Since stocks began selling off on Feb. 20, the S&P 500 has had six days where it’s risen, and all but one of them were big gains of more than 4%. After them, stocks fell an average of 5% the next day.
