About MPM Asset Management Investors 2005 BVIII LLC's insider trades

MPM Asset Management Investors 2005 BVIII LLC is a 10% owner of Somaxon Pharmaceuticals (SOMX). Since Dec 20, 2005, it has reported 3 open-market purchases worth $10.5M and 12 sales worth $8.2M on SEC Form 4. There have been no open-market trades in the last 12 months.

4 sales (38% of the value sold) were made under a Rule 10b5-1 trading plan, which is set up months in advance and runs on a schedule, so they say little about how the insider sees the stock today.

Its filings also include conversions (3 filings), other transactions (1 filing). These aren't open-market trades and aren't counted above.

How to read insider trades

Officers, directors and owners of more than 10% of a company must report trades in its stock on SEC Form 4, usually within two business days. Purchases with their own money are the stronger signal: insiders sell for many reasons (taxes, diversification, a house), but buy for one. See every SOMX insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
