Here are some of the biggest premarket US stock movers today:
Costco (NASDAQ:COST) reported fiscal fourth-quarter revenue that fell short of analyst estimates, as a dip in spending on big-ticket items and lower gasoline prices weighed on the membership-only warehouse chain. Shares in the company dipped by 1.4% in premarket US trading in the wake of the report. They have gained roughly 38.5% so far this year.
Bristol-Myers Squibb (NYSE:BMY) shares jumped after US regulators approved the first new type of schizophrenia drug in decades. The labelling information of the treatment, Cobenfy, does not include a warning about the higher risk of mortality among some elderly patients, granting further support to the stock.
Cassava Sciences (NASDAQ:SAVA) shares slumped after the drugmaker and two of its former executives agreed to pay more than $40 million to settle federal claims that they had issued misleading statements around the outcome of an Alzheimer's drug trial.
Dollar General (NYSE:DG) shares slid after analysts at Citi flagged market share gains made by rival Walmart (NYSE:WMT) would pressure the firm.
HP Inc. (NYSE:HPQ) shares fell after analysts at Bank of America (NYSE:BAC) downgraded their rating of the company to "Neutral" from "Buy" on concerns over its print division.
Online-learning group Udemy (NASDAQ:UDMY) saw its stock price slip after Morgan Stanley (NYSE:MS) lowered its rating to "Underweight" and warned of weak demand.
Wynn Resorts (NASDAQ:WYNN) shares rose after analysts at Morgan Stanley upgraded their outlook for the company to "Overweight", arguing that it has become more attractive thanks to a lower valuation and opportunities in the United Arab Emirates.
Establishment Labs (NASDAQ:ESTA) shares surged after the medical technology company said it had received US approval for its Motiva breast implants.
Bumble (NASDAQ:BMBL) shares dropped after analysts at KeyBanc downgraded their rating to "Sector Weight" from "Overweight", saying the reaction to the dating app's second-quarter earnings was "overdone."
