Closing Bell: Netflix Tops S&P 500; Wall Street Ends 2015 Lower

The S&P 500 ended in negative territory for 2015. Equities have been on a wild ride this year with driving forces including risk of default in Greece, a slowing Chinese economy, the Federal Reserve's first rate increase in nearly a decade, and plunging oil prices. Crude oil ended the session higher, but it had no shot of ending the year with gains. Oil is down more than 30 percent for the year, its second annual loss in a row. Chesapeake Energy (CHK) was one of the hardest hit from the rout in oil prices. Shares have fallen around 77 percent since the beginning of the year, making the energy producer the worst performer on the S&P 500. Netflix (NFLX) was the best performer on the index, climbing more than 130 percent since January. The streaming service has had a stellar year, topped off recently with more Golden Globe nominations than any of the broadcast networks.
