Shares of Detroit Three automaker General Motors (NYSE: GM) have been underwater for most of 2025, with tariffs, EV difficulties, and economic uncertainty depressing sentiment. However, things just swung massively in the right direction. GM’s Q3 2025 earnings were arguably the company's biggest positive surprise recently.
On Oct. 21, GM shares rose 15%, the biggest single-day gain in 2025 and the second-largest since 2010 restructuring. This historic surge stands out long-term. The only day that topped it was March 24, 2020, when markets rebounded from the COVID-19 crash. GM rose 20% that day, while the S&P 500 rose 9%.
