About Troy Cox's insider trades

Troy Cox is an insider at MapLight Therapeutics (MPLT). Since Feb 7, 2018, Troy has reported 2 open-market purchases worth $497K and 5 sales worth $3.3M on SEC Form 4. In the last 12 months: 1 buy ($149K).

2 sales (23% 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.

Their filings also include grants and awards (19 filings), other transactions (2 filings), shares returned to the company (1 filing), option exercises (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 MPLT insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
