S&P 500 Has its Best Week of 2015

Wall Street held up unbelievably well Friday in the face of breaking news on terror attacks and the aftermath. The S&P 500 had its best week of 2015. The Dow had its best week since October 9 and also managed to just finish the day in positive territory for 2015.

But, it was a bad end to the week for popular Mexican chain Chipotle (NYSE:CMG) as the Centers for Disease Control and Prevention reported more cases of E. coli. The CDC said 45 people have been infected with the bacteria in six states including Washington, Oregon, California, Minnesota, New York and Ohio. Shares of Chipotle fell more than 12% and hit a new 52-week low after the report.

Tesla (NASDAQ:TSLA) pumped the breaks Friday. The electric vehicle maker began recalling all 90,000 of its Model S sedans to check for a potential problem with seat belts, according to the Wall Street Journal. This is all due to a single report of a front seat belt not being connected properly. Shares ended the day lower by just under 1%.

The big winners Friday? Retailers! Troubled teen retailer Abercrombie & Fitch (NYSE:ANF) has finally realized sex doesn't sell! The company posted sales and profit that beat expectations and soared 25%. The clothing chain had recently ended its ad campaign that show scantily clad guys and gals.

Nike (NYSE:NKE) stock also saw gains of more than 5%  after announcing a 2-for-1 stock split that will take effect next month. Nike is currently the fourth-highest priced of the Dow's 30 components, but will fall to the 21st-highest priced once the split takes effect.
