As market focus shifted to brimming oil inventories [O/R],energy stocks also fell as oil prices retreated from the year high above $78 a barrel touched earlier in the day.

"The stock market has been strong so there is a natural inclination to take some profits with any sort of earnings weakness," said Ian Nakamoto, director of research at MacDougall, MacDougall & MacTier.
"But it just seems the trend has been to buy on weakness, so even if you have a drop like yesterday it seems to come back here, so there are obviously enough people on the sidelines with cash."
