General Motors (GM) stock has seen a significant increase in its shares due to the sharp drop in crude oil prices, which can improve consumer affordability and sentiment around vehicle purchases. The drop in oil prices came after President Donald Trump announced that the United States had agreed to postpone attacks on Iranian energy assets for five days. This could potentially benefit GM due to its broad portfolio of trucks, SUVs and crossovers. Falling fuel prices can reduce pressure on household budgets and increase demand for new vehicles. Additionally, easing inflation fears can strengthen expectations for auto financing conditions and demand trends. Looking further out, the next major catalyst is the April 28 earnings report.
