From a news posting on Yahoo! (http://news.yahoo.com/evacuations-ordered-tropical-storm-karen-nears-u-coast-031815376.html) "...Oil output in the U.S. Gulf of Mexico was cut in half as oil and gas firms shut platforms and evacuated some workers in preparation for the storm. The Gulf accounts for about 19 percent of U.S. oil production and 6 percent of natural gas output." I'm wondering what effects this will have on oil companies stock with refineries in the Gulf come Monday opening trading session? Is this something that will imply a likely sudden drop we daytraders can capitalize on for a good SHORT position during the first 5 minutes?
