History Says Tesla Stock Swings Hard on Earnings. It Has Moved 8% or More After 10 of Its Last 15 Reports.

Tesla stock has experienced significant volatility following earnings reports, with 8%+ moves after 10 of its last 15 quarterly reports. Seven of these big moves were declines, typically following quarters where operating income fell year-over-year. Ahead of the October 21 earnings report, Tesla faces a high bar: its Q2 2026 operating income was only $398 million, so Q3 would need to quadruple that figure just to show year-over-year growth. The stock's 340x earnings valuation means profit trends heavily influence price movements.
