Has Bill Ackman bit off more than he can chew? Pershing Square disclosed a 9.9% stake in Chipotle.
Shares of the fast food restaurant fell more than 40% from their 52-week highs hit in October.
Is a star activist enough to turn around this closely-followed but troubled stock? The "Halftime Report" desk weighs in.
Pete Najarian is a long-term believer. "Chipotle needs an activist involved," he said. Bill Ackman will speed up the turnaround process, according to Najarian.
The rest of our desk wasn't as bullish.
"What can an activist do to make people want to eat a second or third burrito of the week at Chipotle?" asks Josh Brown. He isn't convinced Ackman can move the revenue needle.
There are many headwinds for a turnaround story here, argued Joe Terranova.
