With markets caught in a volatile pattern of selloffs and rallies, I thought I'd do a quick round-up of what we know (very little) and don't (a whole lot).
(Don't want to hear about markets right now? I've got you. Scroll down to my P.S. for something fascinating.)
Before I begin, I should say: if you're looking for perfect clarity, you won't find it here. From where I stand, the crystal ball looks murky.
