I sold at 58.50. I'm not an officer or insider, just an investor, but took advantage of the runup to exit. I may be old-fashioned, but I do adhere to the "buy low/sell high" strategy and tend to do this consistently which might explain why I made 60% net on my stock investments since Jan. 2012.
I usually am the same, but I blew it this time, focusing instead on Reuters & S&P's research that CSTR would leap to $62. I figured CSTR would hit $62 early today, but instead, it fell like a rock.
It hit my sell price of $52 today, however, I am going to ignore it and stay long for a while.
I guess my failure to sell is the reason I don't come close to your 60% return.
