That's going to dominate the market today until we get more information. A potential story like this from an OPEC producer brings up the worry that oil can spike to new highs very easily. We see the reaction in equities when oil goes higher. It stops equities in their tracks.
I would characterize this as a correction long in coming. We're coming off of this tremendous run, plus you've got oil prices near all-time highs and the prospect of higher interest rates through the end of the year, and so you're seeing some profit taking.
