Tesla Stock Suffered Its Worst Week Since 2022, Falling 18% as Investors Balked at Elon Musk's Robotaxi and AI Spending Plans

Tesla stock plummeted 18% in a single week following Q2 earnings, marking its worst week since 2022. Despite strong revenue exceeding $100 billion in trailing-12-month sales, investors were concerned about shrinking operating margins (down to 1.4%), negative free cash flow of $1.1 billion, and massive capital expenditure plans including $25 billion in capex for the year and plans to borrow up to $30 billion. The sell-off reflects investor skepticism about Musk's ambitious robotaxi and Optimus robot investments, which remain far from commercialization.
