In economic news, two reports on Monday pointed to more growth in the manufacturing sector. The latest Institute for Supply Management PMI release registered a 50.1% reading (anything above 50 indicates expansion). Printing and furniture manufacturers reported the strongest growth in October, while producers in the wood and computer industries reported the weakest results. Separately, the Markit PMI report found that manufacturing production "increased at a robust and accelerated pace in October."

Meanwhile, there were a few standout stock drops on Monday -- even in the broadly higher market. Dow giant Visa (NYSE:V) slipped after announcing its fiscal year 2016 outlook. And fast food giant Chipotle (NYSE:CMG) fell in the wake of an E. coli outbreak scare.

Visa sees a soft 2016 ahead
Visa was the single worst performer in the market today, falling 3%. The global payments giant announced a massive acquisition in conjunction with Monday's third-quarter earnings report: It's buying Visa Europe for over $20 billion.

The quarterly results met Wall Street's expectations: Sales rose 11% to $3.6 billion as profit improved by 12% to $0.62 per share. Visa's operations continued to benefit from strong, double-digit transaction volume growth.

The Visa Europe announcement wasn't much of a surprise, either. Reports last week suggested the deal was imminent, and even pegged the $23 billion price almost exactly right.

Yet investors might have been spooked by Visa's weak outlook for the coming fiscal year. Management forecast a revenue growth slowdown due to several issues that will be pinching results. Those include exchange rate swings and a soft selling environment in many markets. But executives said that while reported sales and profit results will be weak, the core business is as strong as ever. "The key underlying drivers of our business remain very healthy," Chief Financial Officer Vasant Prabhu said in a conference call with investors Monday morning. "Although fiscal 2016 reported growth rates will be negatively affected by a strong U.S. dollar and an uneven global economy, we are well positioned for strong success in 2017 and well beyond," CEO Charlie Scharf.

Chipotle works to contain an outbreak
After opening lower by 5% Monday, Chipotle's stock recovered to finish down 2%. Investors learned over the weekend that the tex-mex chain had to temporarily close 43 restaurants in Washington and Oregon after two dozen of its customers fell ill with exposure to E. coli bacteria. State health officials, and the company, are investigating the incident, which has so far resulted in just a few hospitalizations.

Even if the outbreak is contained at that small level, it will have a negative impact on Chipotle's results. Besides the lost sales from closed locations, it is likely to push customer traffic temporarily lower in the region thanks to the extra focus on health concerns. And if the outbreak is tied to a certain ingredient or supplier, Chipotle may need to make changes to the menu, which would raise costs.

Yet the company has been through incidents like this before and made the adjustments needed to fix the issue before it seriously hurt the brand. That's why a problem like this is worth watching, but not a huge concern for long-term investors.
