About Chester Billingsley's insider trades
Chester Billingsley is Chief Executive Officer at Mentor Capital (MNTR). Since Aug 23, 2016, Chester has reported 58 open-market purchases worth $112K and 62 sales worth $2.7M on SEC Form 4. In the last 12 months: 25 buys ($5K).
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 (3 filings), conversions (1 filing), other transactions (1 filing), grants and awards (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 MNTR insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
