According to Yahoo!Finance, Neovasc (NVCN) is, “…a specialty medical device company, develops, manufactures, and markets cardiovascular devices worldwide.”
From the low in 2009, Neovasc increased +98,900%. At the peak in February 2015, the stock collapsed to the current price of $2.58. Again, the high price is a reflection of the reverse stock splits that have occurred to ensure the trading on the stock exchange, in spite of needing to be delisted in early 2016.
