Zepp Health (ZEPP), owner of Amazfit smartwatches, is trading well below book value (~0.4x) at ~$80M market cap despite 34% YoY revenue growth and repositioning as a Garmin alternative with improved products (better GPS, battery, AMOLED, titanium models). Key risks include ongoing net losses (~$18M in Q1), hardware commoditization, unproven brand turnaround, and potential inventory/asset quality issues.
