13G Filing: Visium Asset Management Has Nearly Doubled Its Stake in La Jolla Pharmaceutical Co (LJPC)

We are seeing a boatload of 13G filing activity at the moment and investment firms disclose their positions as of the end of 2015 (we are not publishing these filings, as they are outdated). One of the more noteworthy relevant filings is this one submitted to the SEC by Jacob Gottlieb‘s Visium Asset Management. This filing details the investor’s updated position in La Jolla Pharmaceutical Company (NASDAQ:LJPC), including the fact that it now holds 1.18 million shares of the company (you can see these figures in the table below), nearly double the 630,000 shares that Visium reported holding as of the end of September. Given the investor’s prominent position in the stock, we recommend paying close attention to the details in the following filing if you’re considering how to trade the company’s stock right now.
