Billionaire hedge fund manager Bill Ackman's first tweet is a photo of him at Chipotle

Bill Ackman’s first tweet is about Chipotle, a company his hedge fund Pershing Square has taken a big stake in.

It was his first tweet since he launched the Twitter profile late in June

Chipotle’s stock dropped on Tuesday after Business Insider’s Hayley Peterson broke the news that a restaurant in Virginia had closed due to food poisoning. The stock closed down 5.51%. 

On Tuesday night, Jeff Gundlach, the founder of DoubleLine Funds, added his voice to the criticism of Chipotle on Twitter.

Gundlach tweeted: “Should CMG expand menu to get customers back?” Raw Egg Breakfast Burrito, anyone? Oh well, bulls have that 0% dividend going for them, anyway!”
