What investment tradest closest to prices at the gas pump?

I think I have a good ability to sense if the price at the pump is going to go up or down, so I'd like to trade on that. The problem is that I don't know what to trade.

I'm looking at the prices found in the charts on gasbuddy.com and trying to find an investment that matches it. The etf ticker symbol USO is somewhat close, but not close enough. The price of gas 9/10/06 and 3/22/07 is about $2.60/gallon. However, the price of USO on 9/10 was $60.04 and it's $49.77 now. That's a huge difference.

As other responders have already mentioned, the refiners tend to track the price at the pump pretty closely. VLO, FTO. I believe that oil stocks in general also track the gas prices real well. In fact I would grin every time gas prices went up last summer because that ment the prices of the oil stocks I owned also went up.

There is nothing like having a few oil stocks and refiner stocks in ones portfolio to put a smile on ones face as the pump prices rise.

Valero. Ticker is VLO.

As far as I know trading related to gas prices is oil. The problem with that is that oil is traded on the commodities market. The commodity market is very difficult to get into and you need a very large sum of money to even be allowed to trade, something like $250,000 to start. As far as the open market goes, you could look into some different gas station companies. I think Citgo and Opex are traded on the open market. I hope this helps you.

There is a gasoline futures contract, 1,000 barrels per contract. But I'm not sure that's exactly what you're looking for

Get a quote for a " refiner" TSO...FTO..WNR....then look at " competitors".....the refiners very closely follow gas prices..( usually)...and price of crude doesn't seem to figure in at all.
P.S. ALJ a refiner and retailer in Calif. area ( where prices are usually high)
