Momenta Pharmaceuticals, Inc. (MNTA)

I use data directly from SEC filings. That’s how I construct the table of insider shareholdings and options that resides in the MNTA ‘ReadMeFirst’ (#msg-116368010).

For a rough snapshot of insider and institutional holdings once a year that requires no arithmetic, you can use the table in the latest DEF14A filing (http://www.sec.gov/Archives/edgar/data/1235010/000104746915003889/a2224436zdef14a.htm#dq12001_security_ownership_of_certain___sec02525 ); however, this info isn’t up to date—the ownership %’s in the table preceded MNTA’s public offering in May 2015.
