Here's Why Amarin Corporation plc Is on the Rise Today

Shares of Amarin Corporation plc (NASDAQ: AMRN), a cardiovascular health-focused biotech, popped 12.9% higher this morning after reporting second-quarter earnings. Investors cheered the record-breaking results early, but the stock's gain has settled to about 3.4% as of 11:35 a.m. EDT on Wednesday.

Amarin's future is tethered to success for Vascepa, a triglyceride-lowering fish-oil derivative that earned approval in 2012, and got off to a fairly slow start. It looks like patience is paying off for early investors, though, as second-quarter sales of the drug rose 37% over the same period last year, to $44.9 million.
