Lululemon was trimmed to underperform from hold, with Jefferies noting increased competition and a slowdown in COVID-related demand surge. Under Armor was downgraded to hold from buy amid concerns about management volatility and lagging fundamentals.

Uber Technologies (UBER) – According to a report by the International Consortium of Investigative Journalists, Uber has campaigned extensively to relax labor and tax laws, using so-called “stealth technology” to block government scrutiny and gain public trust to win. Uber issued a statement saying it had made mistakes in the past and is a different company today. Uber lost 2.6% in premarket promotions.
