Wall Street capped its best quarter since 1998 Tuesday with more gains, a fitting end to a stunning three months for investors as the market screamed back toward its record heights after a torrid plunge.

The S&P 500 climbed 1.5 percent, bringing its gain for the quarter to nearly 20 percent. That rebound followed a 20 percent drop in the first three months of the year, the market’s worst quarter since the 2008 financial crisis. The plunge came as the coronavirus pandemic ground the economy to a halt and millions of people lost their jobs.

“It’s the first time you’ve had back-to-back (quarters) like this since the 1930s,” said Willie Delwiche, investment strategist at Baird. “It’s pretty unprecedented.”

The whiplash that ripped through markets in the second quarter came as investors looked beyond dire unemployment numbers and became increasingly hopeful that the economy can pull out of its severe, sudden recession relatively quickly. The hopes looked prescient after reports during the quarter showed that employers resumed hiring again and retail sales rebounded as governments relaxed lockdown orders meant to slow the spread of the coronavirus.
