The ultimate deterrent for the oil market is when the price becomes too expensive for people to fill their tanks.

Oil markets are already reacting. We've already seen that Iran is willing to talk about using oil as a weapon, and I think the markets are taking that threat seriously.

We're still seeing some rotation into more cyclical stocks ... such as consumer products makers, and industrials, ... We quite like oil stocks as well.
