U.S. stocks rebounded on Tuesday a day after worries about slowing economic growth kept investors on edge and knocked major indexes lower.

The Dow Jones Industrial Average gained 94 points, or 0.4%. S&P 500 added 0.2% and Nasdaq Composite rose 0.1%. The blue-chip Dow climbed 250 points to touch an all-time high at one point on Monday, but ended the session nearly 100 points lower. The Dow and S&P 500 were within 1% of record highs on Tuesday morning.

The 10-year Treasury yield was stable on Tuesday, easing some of the concerns about slowing economic growth, after falling back to near 5-month lows on Monday. However, oil prices continued to fall.

The spread of the delta coronavirus variant continued to keep investors on edge. The seven-day average of daily coronavirus cases in the U.S. reached 72,790 on Friday, surpassing the peak seen last summer when the nation didn’t have an authorized Covid-19 vaccine, according to data compiled by the Centers for Disease Control and Prevention.

However, on the positive side the U.S. reached the 70% Covid vaccine milestone, according to the CDC.

Stocks that would benefit most from an economic reopening and more widespread vaccination gained in premarket trading Tuesday. Shares of most airlines were higher in premarket trading, along with Carnival Corp.

“The delta variant of the virus is now rapidly spreading in the U.S. and a modest pullback in activity can’t be ruled out,” Solita Marcelli, CIO Americas at UBS, said in a note. “But any potential slowdown should be somewhat muted.”

Tesla was set for more gains on Tuesday following a 3% pop on Monday.

Shares of Simon Property gained in after hours trading Monday after the mall owner said sales bounced back to pre-pandemic levels, up 80% from a year ago. It also reported a relatively high occupancy rate.

Concern about slowing economic growth triggered a drop in Treasury yields on Monday. The yield on the benchmark 10-year Treasury note fell as much as 8 basis points to 1.15%. Monday’s slide in bond yields followed data showing the U.S. manufacturing sector expanded at a slower pace than a month ago.

A late-day sell-off in economically sensitive stocks like materials and industrials eventually pushed the Dow and the S&P 500 into the red.

Investors are closely monitoring progress in Washington as lawmakers move toward a bipartisan infrastructure bill that would devote $550 billion to U.S. infrastructure. Senate Majority Leader Chuck Schumer aims to rush the 2,702-page legislation through the chamber before a planned monthlong recess starting Aug. 9. 

Meanwhile, the second-quarter earnings season continues with Under Armour shares rising in premarket trading after the company beat estimates on the top and bottom lines. Shares of Eli Lilly were lower after the drugmaker’s earnings came in lighter than expect. Clorox’s stock was also under pressure after a disappointing report.

Through Friday, 88% of S&P 500 companies had reported a positive earnings surprise for the second quarter, which will mark the highest percentage since FactSet began tracking this metric in 2008.

“Rising earnings are providing valuation support,” Terry Sandven, U.S. Bank Wealth Management chief equity strategist, said in a note. “Rising revenue and earnings, generally restrained inflation, relatively low interest rates, ongoing monetary and fiscal stimulus policies and COVID-19 medical progress support our outlook for rising U.S. equities in 2021’s second half.”
