Chipotle Closes 43 Stores Over E. Coli Outbreak

Stocks roared into November, building on a big gain in October.

The Dow turned green for the year, soaring 165 points to 17,828. The S&P gained 24 points and the Nasdaq rose 73 points.

Big earnings movers were announced after the bell Monday. AMC (NYSE:AMC) tipped into the green after hours despite a slight miss on both profit and revenue.

Fitbit (NYSE:FIT) slid after hours despite obliterating expectations for quarterly earnings. The wearable device maker sold 4.8 million fitness trackers and  more than doubled the profit estimate.

Chipotle (NYSE:CMG) took a hit after news of an E. coli outbreak forced the burrito chain to close 43 stores. Twenty-two people in Oregon and Washington who dined at the Mexican food chain have gotten sick. Chipotle is keeping those stores closed until state officials say it's safe to re-open.

A wild ride for wearable camera maker GoPro (NASDAQ:GPRO). It started the session held down by last week's disappointing earnings as it sunk to an all-time low of $24.30. But then GoPro did a 180 to end the day up 2%.

A historic moment for HP  as it makes the split official. HP Enterprise (NYSE:HPE) and HP Inc. (NYSE:HPQ) took to the market in their first day of trade since splitting over the weekend. Hewlett Packard Enterprise rallied at first but ultimately ended the day in the red. Meanwhile, HP Inc., which will sell the printers and hardware, soared nearly 13%.

Valeant (NYSE:VRX) bounced back after hitting a two-year low early in the session. Allegations of inappropriate ties with the pharmacy Philidor have weighed on Valeant, but shares got a boost Monday after an announcement from Citron, the firm that published a scathing report on the company. Citron said it was done dropping bombshells for now, and would not be publishing any new allegations against Valeant despite promising an update.
