Here an idea I thought of last night in bed, I haven't researched it in any way so keep that in mind. There is a tradeable commidity future for Unleaded gasoline, traded on the Nymex I believe...I'm not sure of the contract specifications (i.e time period), but what would stop me from hedging my monthly gasoline purchases? I could buy say $400 worth of the future at the months low, and hedge gasoline prices for the month. I know its not a signifigant savings, but a neat idea nonetheless. For example, if I bought $400 worth of April gasoline at 67.3 cents (this is per litre, Canadian price, and the lowest its been for a while), if the price then went up to 75ish for the rest of the month and I ended up spending an average of 75 on the actual gas for my cars in the amount of $400 total, supposing the future closely follows actual gas prices (something I'd need to check out), I could sell my futures for 75 cents for a profit equal to the premium I spent on the gas over 67 cents, essentially locking in my gas expenditures at the monthly low. This could be done on a yearly basis as well with a better knowledge of the future of gasonline prices...kind of a neat idea, what are your thoughts?
