We view hedge fund activity in the stock unfavorable, but in this case there was only a single hedge fund selling its entire position: EcoR1 Capital. One hedge fund selling its entire position doesn’t always imply a bearish intent. Theoretically a hedge fund may decide to sell a promising position in order to invest the proceeds in a more promising idea. However, we don’t think this is the case in this case because none of the 750+ hedge funds tracked by Insider Monkey identified MRSN as a viable investment and initiated a position in the stock.
