The lack of follow through buying to yesterday's brief rally emphasizes that participants have momentarily refocused on fundamentals.

Besides the Iranian situation, difficulties in Nigeria...have prompted follow-through buying.

A lot of this is 'just in case' buying.

I'm looking for bearish sentiment to warrant a brief rally,

The comments from OPEC officials are taking some of the froth off last week's rally. It looks like OPEC is set to roll over the existing production quota at the meeting this week.

Still, brimming stocks should keep any rally in check, late week cold notwithstanding.
