Is UCO a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The case for UCO is simple: low-cost, diversified exposure to Bloomberg Commodity Balanced WTI Crude Oil Index (2x daily) at a ~0.95% expense ratio, anchored by names like CL, USD. If that is the exposure you want and you do not already own most of it through another fund, UCO is a strong core holding. The catch is concentration in its top names and overlap with broad-market funds you may already hold. Whether it is a buy comes down to whether you want Bloomberg Commodity Balanced WTI Crude Oil Index (2x daily) and at what cost. Not a recommendation; Walnut is not an investment adviser.
What are you buying with UCO?
UCO is a leveraged ETF that seeks daily results, before fees, of 2x (200%) the daily performance of the Bloomberg Commodity Balanced WTI Crude Oil Index, which holds WTI futures spread across multiple maturities. Its net expense ratio is about 0.95%. Because leverage resets each day, holding UCO for more than a day compounds returns in ways that differ from twice the oil price move, and contango in the futures curve adds a further drag.

What's the case for UCO?
UCO is the ProShares Ultra Bloomberg Crude Oil fund, a leveraged commodity ETF that seeks 2x (200%) the daily return of the Bloomberg Commodity Balanced WTI Crude Oil Index, an index built from WTI crude oil futures spread across multiple contract months. Its net expense ratio is about 0.95%. UCO resets its leverage every day, so over multi-day periods its return compounds and diverges from a simple 2x of oil's move. It is a short-term trading tool for bullish oil views, not a long-term holding, and its inverse twin is SCO.
In its favour: it gives you Bloomberg Commodity Balanced WTI Crude Oil Index (2x daily) exposure in one ticker at a ~0.95% expense ratio, which is simple to hold and cheap to own.
What should you weigh before buying UCO?
- Cost vs alternatives: ~0.95% is the fee; compare it to funds tracking a similar index.
- Concentration: check how much of UCO sits in its largest holdings (CL, USD).
- Overlap: if you already own a broad-market fund, you may already hold much of this.
- Tracking scope: UCO only gives you Bloomberg Commodity Balanced WTI Crude Oil Index (2x daily); it will not capture what sits outside that index.
How do you decide if UCO is a buy?
The useful question is rarely “will UCO go up?” It is “does this exposure fit my plan, at a cost I am happy with, without doubling up on what I already own?” Walnut connects your real brokerage so you can see exactly how UCO would overlap with your current holdings, analyze it by chatting through Claude or ChatGPT, and place any trade yourself. You stay in control.
The bottom line on UCO
The bottom line: UCO is a low-cost core building block for Bloomberg Commodity Balanced WTI Crude Oil Index (2x daily) exposure, not a tactical bet on a single name. If you want Bloomberg Commodity Balanced WTI Crude Oil Index (2x daily) exposure and the ~0.95% fee is competitive for you, it does its job well. If you already own that exposure through another fund, adding it mostly doubles a fee without adding diversification. Decide from your goal and your existing holdings, not from where the market sat last week. Walnut is not an investment adviser.
