Thanks for the info and I agree. I don't understand how insider sales of 2M shares and ~8% share dilution adds up to a 16.7% leap in share price in a day. Per Google Finance (mrq) SSTK had roughly 38% institutional ownership. Not sure if a ton of "Sheeple" (hilarious) bought, but it's the best theory I've seen. Perhaps the FB deal got a lot of "Sheeple" to notice SSTK.
