Boston Scientific Corp. (NYSE: BSX) was seemingly on the long way down, until 2013 when the stock kicked into gear and became one of the standout turnaround stories. The stock has actually gained over 200% from the start of 2013, but some analysts think there are even more gains to be had at this company. If the independent research firm Argus is correct, then Boston Scientific shareholders could see an upside of roughly 40% from this current price level.
