While it's true that last year's insiders sales were at prices lower than today, that is more a function of the fact that the share price wasn't this high last year but for two or three days. The fact that insiders took such good advantage of the spikes there were is uncanny in itself, for heavens sake, look at the chart and the dates of insiders sales, amazing!
I believe the reason the price is higher now than last year is because of the expectations of the Ericsson settlement. The fact that the price didn't go even higher shows the market is not as pleased with this settlement as we were led to believe it would be. To me, that signals the end of this run but everyone should make up their own mind about this.
