Tesla is the worst-performing Magnificent Seven stock in 2026, down 22% year-to-date despite strong revenue growth of 21%. However, profitability has deteriorated with operating margins contracting from 4.1% to 1.4%, while R&D and administrative expenses surged. The stock trades at an inflated P/E ratio of 327, with future performance heavily dependent on unproven Robotaxi and Optimus projects.
Axe note: Tesla’s sharp drop despite revenue growth exposes risks in expensive growth stories.
