About this author:

USO is not a long-term proxy for crude oil. Buy-and-hold investors who do not understand the structure of USO will underperform crude. Surprisingly, many investors, judging from their posts, don’t know this even though the information is readily available on the USO web site and elsewhere.

USO holds all its funds in next-month WTI futures. For example, USO started out February fully invested in the March WTI contract. Midway through February USO rolled all its funds into the April contract. The rollover has all been done on a single day, but USO recently decided to rollover over a multi-day period to minimize market impact.

When oil is in contango, far months are more expensive than near months so USO’s rollover loses money. The loss is mitigated somewhat by the interest USO earns on its funds (only 10% of funds are needed to secure a contract). Also when oil is in backwardation the rollover makes money.

However, over USO’s history, oil has been in contango more often than backwardation. Consequently, over its history, USO has lost value relative to oil. The ratio of one USO share to the price of crude was 1.0 when USO was launched. Today the ratio is 0.68. It’s essential to appreciate that this process has NO intrinsic lower limit: a prolonged period of contango can drive USO down indefinitely even while spot oil remains unchanged.

Anyone considering a buy/hold strategy for USO today should be aware that oil has been in very steep contango and likely will remain thus for some months to come. This has been very costly to USO in recent months as a comparison of crude prices to USO readily shows.

In summary, while USO is a useful short-term oil proxy, it should not be used as a long-term proxy without some strategy to minimize value erosion through contango, such as writing monthly covered calls.

Stock position: None.

    Thanks for the info Milan. Is there another ETF or equity you would suggest for someone wanting to go long on crude?

    USL is the 12 month. (They buy all the contracts within the next year rather than just the front month.) However, there's significantly less volume which makes liquidity an issue.

    If you want just the refiners and processors its OIH.

    Good points! There has been a lot written on this recently. USL (USO's sister fund) has longer dated contracts (12Months), lessening the futures role. USL has outperformed USO by a substantial margin YTD.

    Here is one of the articles that mentions it

    PowerShares DB Oil (DBO) also invests in monthly WTI futures but the rollover is done at the discretion of traders who choose the time and month into which to rollover, rather than mechanically like USO. This has benefited DBO considerably over the past three months relative to USO. Up until that time, though, the two funds were similarily affected by contango.

    I am not aware of any way to directly go long crude (renting storage at Cushing aside). However, the smaller oil producers (for example ARD, APA, SU) have near-perfect correlations to spot oil, so you may consider a basket of these stock. Also, DBO and USO work when oil is in backwardation.

    Beaver Pelts... Maybe 200 years ago.. :P

    Would USL or OIH be good mid to long term investments? I got in USO @ $39.00.. Should I continue to dollar cost avg down OR where do you see USO going in the short term??

    USO underperforming the price of crude oil isn't exactly fair, since the contango in the futures market is connected to the cost to hold onto the commodity.

    Really its performance should be compared to the performance of hiring an oil tanker to hold oil and wait in the Caribbean or somewhere. If USO under performs compared to the tanker, then there's an arbitrage opportunity by shorting USO and hiring a tanker, then covering later by selling the physical oil and covering the short.
