Afternoon Market Losers

Rigel Pharmaceuticals RIGL is down 18.76% to $3.68 after disappointing Phase III OKSIRA-2/3 studies results and subsequent downgrades by JPMorgan and Oppenheimer. Dollar General DG has fallen 7.71% to $49.44 following this morning's earnings report. While revenues were in line with analysts' estimates, guidance was lowered. Raymond James downgraded DG two notches from Strong Buy to Market Perform. SolarCity SCTY is currently down 9.43% to $36.92 following yesterday's equally sharp decline. Trading restrictions are lifted for 82 percent of its shares on June 10th. Unilife UNIS has dropped 9.92% to $3.45. The spike down is likely attributed to the company's slide presentation at the Jefferies Conference that occurred at 12:30 PM.
