Shares of Endo International (NASDAQ: ENDP) rose over 37% on Wednesday after the company reported second-quarter and first-half 2018 earnings. The business actually saw total revenue in the first six months of the year fall 26% compared to the year-ago period, while adjusted diluted earnings per share dropped 34% in that span.But the comparisons are a bit choppy because a handful of contributors from last year have since left the company's portfolio.
