Robinhood (HOOD) – Robinhood fell another 2.8% in premarket trading, following a 6.9% Monday tumble. The trading platform operator saw its stock pressured after CNBC reported that PayPal (PYPL) was exploring the launch of its own stock trading platform, as well as SEC Chairman Gary Gensler's comment that a ban of payment for order flow – which constitutes the bulk of Robinhood's revenue – was "on the table."

Designer Brands (DBI) – The footwear retailer formerly known as DSW reported quarterly earnings of 56 cents per share, compared to a 24 cents a share consensus estimate.

Its shares surged 7.5% in premarket trading.

Chico's FAS (CHS) – The apparel retailer's shares rallied 4.5% after the company reported an unexpected quarterly profit. Chico's earned 21 cents per share, compared to consensus estimates of an 8 cents per share loss. Revenue was also well above estimates. Chico's said the results represented the company's best second quarter in eight years.

Textron (TXT) – Textron added 1.8% in premarket action after Cowen upgraded the stock to "outperform" from "market perform," based in part on robust business jet demand as well as an "underappreciated" opportunity in the electric helicopter market.

Uber Technologies (UBER) – Russian technology company Yandex (YNDX) announced a deal to buy out Uber's interest in several food delivery and ride-hailing joint ventures for $1 billion. Uber was little changed in the premarket, but Yandex gained 1.2%.

Support.com (SPRT) – Support.com remains on watch, after soaring 38% Monday, tripling over the past week and bringing its year-to-date gain to more than 1,500%. The technical support company's stock is among heavily shorted stocks that have been targeted by investors on social media. The stock added another 4.4% in premarket trading.

Moderna (MRNA) – Moderna's Covid-19 vaccine produced more than twice the number of antibodies as the Pfizer-BioNTech vaccine, according to a study published by the Journal of the American Medical Association. Moderna shares had been under pressure following the suspension of 1.63 million doses in Japan on contamination concerns, and a temporary hold on two vaccine lots in the Gunma and Okinawa prefectures which were ultimately cleared for distribution. Moderna rose 1.4% in the premarket.

NetEase (NTES) – NetEase reported better-than-expected earnings for its latest quarter, with the China-based online gaming company seeing revenue in line with forecasts.
