An odd title, I suppose....
Art Cashin is a floor trader of Union Bank of Switzerland (UBS) and appears regularly on CNBC where he discusses some of the technical aspects of market trading.
On two occasions I'm aware of - once today, and once Monday - he has made a pointed comment that stock trading might be substantially affected by a "geopolitical event" associated with Ramadan. Ramadan apparently starts in the U.S. on the 22nd of August.
Here's a link where some other people are posting a few items about it, so at least there is some confirmation I'm not imagining things.

I have heard that Iraq is having some disruption; and North Yemen seems to have a Shiite insurgency that concerns Saudi Arabia - but those conflicts don't seem likely to have an effect on U.S. stock trading.
So...does anyone have any thoughts on the matter? (assuming it doesn't violate OPSEC, of course.)
