Stocks closed up more than 4% on Wednesday afternoon, erasing all of yesterday's losses. The S&P 500 is 7.5% below record levels seen in mid-February.

Driving the news: The gains in the stock market were led by health care stocks, which analysts say got a boost from a strong Super Tuesday performance by Joe Biden — a candidate whose policies would be more favorable to the sector than those of Bernie Sanders. UnitedHealth, the country's biggest health insurer, had its best day in 10 years.

Between the lines: The near-daily swings of 2% or more in the past week have been tied to improving or worsening prospects for the global economy and the coronavirus — plus the willingness for governments and central banks to step in and lessen the blow.

Health care stocks surge after Biden's Super Tuesday wins

Health care stocks soared Wednesday, led by double-digit percentage gains from major health insurers Anthem, Centene, Cigna, Humana and UnitedHealth Group.

The big picture: Nothing has changed with the health care industry, which is still printing money. But Joe Biden's Super Tuesday victories reassured Wall Street of his chances of beating Bernie Sanders and "Medicare for All” — and that a Biden presidency or a Trump re-election will keep the lucrative status quo in place.

Stocks closed up 6% on Tuesday afternoon, making up almost half of the losses from the stock market's worst day since 1987.

Why it matters: Stocks rose as measures to shield companies and the economy from the coronavirus impact — including an announcement by the Fed and a White House stimulus plan that includes sending cash payments to Americans — came to light.
