Why 3D Systems Stock Dropped 12.8% Today

-- 3D Systems (NYSE: DDD) is giving back some gains Wednesday. 3D Systems reported eight times the pro forma profits it was expected to earn this week (according to stock analysts), and its earnings when calculated according to generally accepted accounting principles (GAAP) were twice its pro forma number -- $0.36 per diluted share. As for the sell-off today, however, chances are what we're looking at is a simple case of investors taking profits after betting correctly on a 3D Systems earnings beat.
