Twitter Slumps on High Volume; Crude Oil Falls to March Low

Twitter (TWTR) slid to all-time lows on heavier-than-normal trading volume on Monday before recouping some of those losses. The social network has plummeted 20% since reporting earnings last Tuesday after management warned on user engagement growth. It was a bumpy afternoon session as stock losses accelerated in line with cratering crude oil prices. Benchmark indexes had moved off session lows by the close, though remained in the red. The energy sector was the worst performer after crude oil closed at its lowest level since March. Major oilers Chevron (CVX), Exxon Mobil (XOM) and PetroChina (PTR) each took a big hit. A slide in oil proved a boon to airlines, though. Delta Air Lines (DAL), American Airlines (AAL), Southwest Airlines (LUV), and United Continental (UAL) were all trading higher.
