Walmart, Home Depot — The retailers’ shares rose about 5% each after both companies reported better-than-expected earnings for the most recent quarter.

Bed Bath & Beyond — The home retailer’s shares skyrocketed about 64%. At its highest, shares added more than 70% to touch an intraday high of $28.60 Tuesday amid multiple trading halts due to volatility. The rally came as retail traders active on social media piled into the stock, encouraged by news that GameStop chair Ryan Cohen placed another bet on the struggling retailer.

Nu Holdings — Shares of the Warren Buffett-backed digital banking company surged more than 23% after the firm reported quarterly revenue that rose 230% from a year earlier.

ZipRecruiter — Shares of ZipRecruiter slipped 5% even though it posted second-quarter results that were better than expected. The company said it sees employers pulling back on job postings.

Zoom Video — Shares of the video teleconferencing service fell about 5% after Citi downgraded the company, saying growing competition from Microsoft Teams could push the stock down 20%.
