Oil ETFs miserably fail at replicating the spot price of West Texas Intermediate (WTI) crude. If you'd like to learn why this is so, you may wish to review a well-written

that explains contango and backwardation.

However, my goal is far more basic. I only wish to help investors visualize just how far off the performance mark an oil ETF can be.

The largest oil ETF,

United States Oil

(USO) - Get Report

, has $2 billion in assets. Yep ... that's "billion" with a "b." And the stated goal for USO is "to reflect the performance, less expenses, of the spot price of West Texas Intermediate (WTI) light, sweet crude oil."

How well did United States Oil do at achieving its stated goal over the last year or so? Well, from Feb. 2, 2009, to Feb. 23, 2010, the spot price of crude gained 100% from $40 per barrel to $80 per barrel.

In contrast, USO gained 35%.

Sure, there are a few other exchange-traded funds and notes that endeavor to replicate oil's movement in some way, shape or form. The

is a popular exchange-traded note. As a note, you actually have the credit risk of

, as well as the volatility of the underlying futures contracts for the commodity. The reward? 35%.

Meanwhile, other ETF efforts that use commodity futures contracts,

(USL) - Get Report

and

PowerShares DB Oil

(DBO) - Get Report

, did a little better, at 45% and 50%, respectively. In fact, they may even have accomplished their stated goals for the futures market.

Still, let's face it. Investors who invested in these oil ETFs did so because they were bullish on the commodity. Instead of getting 100%, they got one-third or one-half of the upside. That's more than a little bit of a performance disappointment.
