Here’s the chart of USO, an oil ETF that moves close to the price of oil. It’s not suggested for a long term investment due to issues with contango and how the ETF is structured. But for a short term hedge against increased oil and gas costs, you can purchase it to help offset those costs. The charts big, just click on it to see the larger version. Let me know if that doesn’t work.
The way to figure out how much to buy, is to guess at what your increased cost will be. I can’t do that calculation for you, since you only know how much you drive and how much gas you use. For simplicity sake, say it’s $1000. Then look at the price of USO. To off set a $1000 increase in your gas costs, you have to make some assumptions. If oil goes through the roof here, back up to 150/barrel, the ETF will shoot up. Oil closed Thursday at 112. So from 112 to 150 is a 34% gain. With USO at 45ish, that same gain suggests it can go up to 60. For a profit of 15/share. $1000/15 = 67 shares.
But don’t forget, there’s a downside to hedging. If oil crashes, you will lose money on the investment.
67 shares at $45 is only $3000. To invest less than that, you can buy UCO, which moves at 2x the rate of movement in USO. So you can hedge the same amount with less initial outlay.
The monthly/weekly/daily chart is below. Let me know if you have any questions. If I made any mistakes in the math above, let me know. It’s early and I ran through it very quickly.
