would you buy the oil dip?

Today the whole energy sector heavily dumped. Exxon Mobil to 85 from its recent high of 105
Chevron to 150 from 180 highs earlier this month.
Oil down to $110 from $118 today. Do you see this dip as a start of a turn around, or do you see it as a buying opportunity?

Demand is still high, and supply isn't likely to go above what it already is. What is your thesis on big oil companies going forward this summer and later this year?
