I've not studied the mogas market specifically, but most markets are
based on speculation, not current conditions. That basically means that
any benefit associated with the effects of Katrina are already built
into the price of gas. Its just like the stock market. When a company
announces a great new money making opportunity, you don't have to wait
for it to pay off in order to see the stock price go up, the stock
prices goes up right away on the expection (as long as investors see it
as realistic). This is call the "perfect market theory". As long as
everyone has the same knowledge base of information (something the SEC
tries to assure) markets will automatically price based on that fugure
information, not the current situation.

So, in short, I"m saying that any benefit of the end of Katrina to gas
prices has probably already been reflected in the market. It would be
interesting to see what fuel futures are selling for right now.
