Stocks south of the border ripped higher on Wednesday as tech shares clawed back some of the steep losses that pushed the NASDAQ Composite into correction territory.

The Dow Jones Industrials regained 510.96 points, or 1.9%, to 28,011.85.

The S&P 500 pointed upward 69.23 points, or 2.1%, to 3,401.07.

The NASDAQ Composite popped 277.92 points, or 2.6%, to 11,125.61.

Shares of Tesla, which had their single worst day ever on Tuesday dropping 21%, rose 6.7% Wednesday. Apple, which lost more than 6% in the previous session, was up by 5%.

Those two stocks, along with Microsoft, Netflix, Amazon, Alphabet and Facebook, lost $1 trillion in market value the last three days. All seven were rebounding Wednesday.

The moves Wednesday came as investors shrugged off a setback with a coronavirus vaccine and disappointing earnings news.

AstraZeneca said said a late-stage trial of its COVID-19 vaccine candidate has been put on hold due to a suspected serious adverse reaction in a participant in the U.K. However, the Financial Times later reported the trial might resume next week, lifting AstraZeneca shares off their session lows.

Shares of athletic retailer Lululemon fell 8.1% and messaging platform Slack fell 14.3%. Those losses came despite both companies reporting better-than-expected earnings.

Prices for the 10-Year Treasury lost ground, pushing yields up 0.7% from Tuesday’s 0.68%. Treasury Prices and yields move in opposite directions.

Oil prices regrouped $1.40 to $38.16 U.S. a barrel.

Gold prices gained $10.30 to $1,953.50 U.S. an ounce.
