CarMax Inc. (KMX) closed at $55.60 on October 31, 2026, a decline of 0.96% over the prior 24-hour period. The session-end dip trimmed modest gains but left the used-vehicle retailer's market capitalization at $7.97 billion.
Despite the single-day pullback, the stock has risen 7.86% over the past seven days, reflecting a meaningful shift in short-term momentum. The 30-day picture shows a more measured advance, with shares up 0.93% over that span.
The combination of a strong weekly gain and a slight daily retreat suggests KMX has experienced notable upward movement in recent sessions before cooling heading into the weekend. Over the broader 30-day window, the stock has held marginally positive territory.
CarMax operates one of the largest networks of used-car dealerships in the United States. Its shares continued to trade at the $55.60 level as market participants closed out the October 31 session.
