Ariad has had more of these sales than pretty much any biotech I have seen for a while. With the exception of Berger, pretty much every officer has had some. Clackson has had more than most.
MNTA—I've seen a couple of 10b5-1 Plans where all the participants went with the same algorithm.
You’re hypothesizing that MNTA’s eight insiders* with 10b5-1 plans not only employ the same trading algorithm, but also that the algorithm happens to specify a significantly higher price threshold for a sale beginning on or about 9/1/12—a date with no particular relevance to MNTA’s compensation plans or business development. Possible, I suppose, but not likely.
