Context

• This was an option exercise followed by same-day open-market sales of the acquired shares (common practice to cover exercise cost and taxes). The SEC code M denotes option exercise; S denotes open-market sale.
• Sales by insiders are routine and do not, by themselves, indicate whether they view the company more or less favorably. Purchases tend to be a stronger signal of insider conviction.
