About Neil Gregory Almstead's insider trades
Neil Gregory Almstead is Chief Technical Ops Officer at Ptc Therapeutics (PTCT). Since Mar 19, 2014, Neil has reported no open-market purchases and 66 sales worth $44.2M on SEC Form 4. In the last 12 months: 14 sales ($20.1M).
1 sale (0% of the value sold) was made under a Rule 10b5-1 trading plan, which is set up months in advance and runs on a schedule, so it says little about how the insider sees the stock today.
Their filings also include option exercises (16 filings), grants and awards (13 filings). 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 PTCT insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
