Cramer's 'Mad Money' Recap: Metrics Matter

Two controversial stocks are Capital One(COF Quote) and United Health Group(UNH Quote), the latter of which Cramer owns for his charitable trust, Action Alerts PLUS.

Cramer said to hold off on UnitedHealth, which has been a terrific performer but still hasn't worked out its kinks with management.

Capital One is looking like a bear's dream. Because it has reported a rise in loan delinquencies, Cramer said to stay away until after reports earnings on Thursday.

A bright light on the horizon is Continental(CAL Quote), which "has more momentum than any stock I know," said Cramer. He also recommended Merrill Lynch(MER Quote).

CarMax Talk

The business of buying and selling used cars is probably one of the most misunderstood, said Cramer.

The company that excels and does best in the group is CarMax(KMX Quote), he said.

Cramer welcomed CarMax CEO Tom Folliard and asked him why the used-car business is so good and why Wall Street doesn't get it.

Folliard said the difference between the way his company operates compared with traditional car dealers is far more dramatic than most people realize. "We have a huge selection of cars, no haggle price, guaranteed quality, a money-back guarantee and great employees," he said.
