management turn over, got semel out who was wasting money
panama is a big step forward toward improving monetization, which is basically free money that had been giving away
i think the market overreacted to some past earnings reports, especially in relation to google's
i expect very good q2 numbers due to panama ramping up, which seems to be coming to fruition based on some comments semel made before he left

edit to add:
yes there's other quantitative reasons, but i am obviously half assing this explanation
they will get bought by ms, yes i know that there was already a rumor and it fell through
