AutoNation (AN) soared after it named its second new CEO this year, tapping its chief financial officer, Cheryl Miller, for the top job.
Miller, 47, succeeds Carl Liebert, who the Fort Lauderdale, Florida, car retailer said in a statement was leaving by mutual agreement to pursue other interests.
Liebert had been named CEO in February. He had succeeded Mike Jackson, who had been chief for two decades.
Jackson, who is now AutoNation's executive chairman, told The Wall Street Journal that Liebert, who was new to automotive retail, was not a good fit in the position.

At AutoNation she holds the titles of president and CEO and she was named to the board. Miller is also a director and chairwoman of the audit committee at Tyson Foods.
The company also named its executive vice president of sales, Jim Bender, to the post of chief operating officer.
