Check out the companies making headlines in midday trading.

Robinhood — Shares of the trading app dropped more than 14% after the newly public company said in a filing that existing shareholders will sell close to 97.9 million shares over time. The commission-free broker said it will not receive any of the proceeds from the stock sale of 97,876,033 shares of its Class A common stock. The stockholders were among those who came to Robinhood’s rescue during the historic trading mania earlier this year.

Cigna — The insurance company’s shares fell more than 11% despite a better-than-expected quarterly earnings report. Cigna reported quarterly earnings of $5.24 per share on revenues of $43.11 billion. Analysts expected earnings of $4.96 per share on revenue of $41.26 billion. However, the company noted a headwind of higher medical costs.

Fastly — Fastly shares plunged over 7% following its earnings report Wednesday, which showed a loss of 15 cents per share for the second quarter, compared to the 17-cent loss analysts had estimated. The cloud software provider missed on revenue forecasts and said its June network outage will continue to affect results for the rest of the year.

Wayfair — The furniture and home goods retailer saw shares jump about 10% after reporting earnings. Wayfair topped earnings estimates, reporting $1.89 per share, but missed slightly on revenue, reporting $3.86 billion compared to the estimated $3.94 billion. The company said active customers grew 20% year-over-year to 31.1 million. 

Etsy — Shares of the e-commerce name tumbled about 7% after user growth numbers came up short of estimates. During the second quarter the company earned 68 cents per share, compared to the 63 cents analysts surveyed by Refinitiv were expecting. Revenue came in at $528.9 million, also ahead of the expected $524.7 million.

Booking Holdings — Booking Holdings stock jumped more than 6% despite missing Wall Street expectations for quarterly earnings on Wednesday. The company — whose brands include Priceline, Kayak and other travel services — lost an adjusted $2.55 per share for the second quarter, wider than the loss of $2.04 per share analysts anticipated. However, revenue came in above estimates as travel demand jumped.

Edgewell Personal Care — The maker of personal care products saw shares jump 4.5% after reporting quarterly earnings. Edgewell reported earnings per share of 89 cents and revenue of $573.7 million, both of which beat Wall Street forecasts, according to Refinitiv. The company also raised its full-year earnings guidance.

Roku — The streaming service device company’s shares slid more than 2% after Roku reported weaker-than-expected user growth during the second quarter. The company did, however, beat expectations on both the top and bottom line. Roku earned 52 cents per share on $645 million in revenue. Analysts were expecting 13 cents per share on $618 million in revenue, according to estimates from Refinitiv.

Becton Dickinson — Medical tech company Becton Dickinson’s stock fell roughly 4% despite reporting second-quarter earnings of $2.74 per share, which beat analysts’ estimates by 30 cents. It also beat on revenue, reporting $4.89 billion versus the forecasted $4.51 billion.

Moderna — Moderna shares are down about 1.8% even after it released better-than-expected earnings and revenue as well as positive vaccine protection durability data this week.
