Why SUPERVALU, GOL, and Pacira Pharmaceuticals Jumped Today

Friday was a terrible day for the stock market, with major benchmarks plunging on news that trade tensions between the U.S. and China will likely ratchet up another notch. The U.S. announced plans to add another $100 billion in tariffs on imports from China, responding to China's imposition of retaliatory tariffs following the initial U.

S. move on steel and aluminum imports. Investors also reacted negatively to the fact that despite these macroeconomic and geopolitical issues, Fed Chair Jay Powell stayed the course with the central bank's plans to continue raising interest rates throughout 2018. Even though markets plunged, some stocks managed to post gains. SUPERVALU (NYSE: SVU), GOL Linhas Aereas Intelligentes (NYSE: GOL), and Pacira Pharmaceuticals (NASDAQ: PCRX)were among the best performers on the day. Here's why they did so well.
