The activists going after United Continental Holdings should go after someone else, CNBC's Jim Cramer said Tuesday.
"Why can't these guys go after someone who didn't do a good job?" Cramer asked on "Squawk on the Street." "This is ridiculous; this is a good stock and getting better."
Earlier Tuesday, activist investment firms PAR Capital Management and Altimeter Capital said in a letter they will nominate six members to the board of directors, including former Continental Airlines CEO Gordon Bethune.
