The insider sale info was a month after the sale. I just find it interesting that a large group of insiders made the decision to sell in August, the same month that interest rates went up and the refinance market died. For your sake I hope you are right. I sold as too many of them sold at the same time which would be about the same time as a monthly board meeting, the middle of the month.
Insiders lock in profits just like others. They often have bought low priced options and take profits at a certain point. If I had as much stock in a company as most of them do, I would take some profit and diversify even if I thought the stock was still going to go up. Just look at how many shares of RBAK insiders sold in the last couple of months (months) at half the price it is selling for today. Insider sales is just one of many things to look at when choosing a stock. It is not a crystal ball. People that shorted this stock based on insider trading have had a bad time the last couple of days.
