if we can agree that the executives of the company sold at the right time of Poet's history ,we must also agree that this last purchase by the executives, which was sizeable ,was at the right time. It would follow that the executives must be expecting a good return on their investment , the same same good return they received when they sold at the highs of Poet's value.
Therefore, don't be swayed by the naysayers who constantly state that Poet overpromises and underdelivers. I believe the executives bought because they know that contracts and revenues are imminent.
As the Brits would say, " steady " and it will work out.
