Why Did Allurion Stock Surge Over 50% Today?

Allurion Technologies Inc. (ALUR) saw its stock surge over 50% today after the U.S. FDA granted premarket approval for its Allurion Gastric Balloon System, which includes the swallowable Allurion Smart Capsule. This non-surgical weight-loss device offers an alternative to GLP-1 medications and bariatric surgery, targeting a large market of over 80 million Americans. The capsule is designed to be swallowed, filled with fluid, and remain in the stomach for approximately four months, aiding weight loss before naturally passing out of the body.
