The stock markets in New York ended the day mixed as crude oil prices rode a roller coaster, more quarterly results rolled in, and one company shook everything up.

The Dow Jones Industrial average gained 0.1 percent to 10,697.59 and the S&P 500 also was up 0.1 percent to 1,245.03, but the Nasdaq composite lost 0.1 percent to 2,216.81.

The shake-up came as German company Adidas agreed to purchase Reebok, which sent shares in Reebok up by 30 percent to $57.14. When joined the two companies will form the world’s second-largest sporting goods company, smaller than only Nike. Nike gained 1.3 percent to $86.92 on the news.

The airline sector did not do nearly as well, with the Amex airline index falling 1.5 percent to close at 50.83. Delta Airlines fell 8.3 percent to $2.32, its lowest share value in 43 years, as investors worried that the carrier was getting closer to bankruptcy. Northwest Airlines declined nearly 8.6 percent to $4.37 on the news that union representatives had walked out on contract negotiations. Skywest lost 1.3 percent to $20.82.

Time Warner lost 0.9 percent to $17.27 on a quarterly report that showed its quarterly earnings falling on a $321 million loss that came in the wake of a $2.5 billion settlement in a securities fraud case filed by shareholders.
