General Motors Shares Fall 6.8% as Cost Warning Overshadows Q3 Beat

General Motors (GM) shares fell 6.8% despite beating Q3 earnings and revenue forecasts. The drop was driven by lower-than-expected full-year earnings guidance and rising costs. GM's adjusted EPS was $3.70, beating estimates, and revenue hit $50.02bn, surpassing consensus. The company also announced a $20bn share buyback plan.
