CarMax (KMX -1.61%), the leading omnichannel seller of used vehicles, was hit hard after its latest update. CarMax Auto Finance income declined 11% to $103 million as the provision for loan losses rose to $142 million from $113 million a year ago. Highlighting CarMax's long-term confidence in the business, management repurchased $180 million of stock during the period. Second, digital capabilities continue to support the omnichannel approach; management said 80% of retail unit sales used its digital tools in the quarter. After this week's sell-off, the stock looks attractive for patient investors.
