What COMT is, in plain words.
COMT holds S&P GSCI futures chosen for the best roll yield, plus cash and short-term notes. The fund is managed by iShares, trades on Nasdaq in U.S. dollars and launched on Oct 15, 2014. On Nov 9, 2026 it held $1.29B in net assets and its expense ratio was 0.48%. COMT follows the S&P GSCI with a dynamic roll rule and issues a 1099.
Investors search for COMT ETF because they want a clear answer to four practical questions. What does it cost to hold each year, what does it pay, what is actually inside, and how does it fit in a Roth IRA, a traditional IRA or 401(k), or a taxable account. This guide answers each one with dated figures from the issuer, and marks anything the issuer page does not publish as Not captured.
Key takeaways
- What it is. COMT holds S&P GSCI futures chosen for the best roll yield, plus cash and short-term notes.
- Cost. Expense ratio 0.48%, about $48 a year on $10,000.
- Income. Trailing yield 4.96%, paid annually.
- Risk. Commodity prices can fall sharply in a weak year.
It suits you if
- You want exposure to commodity prices as a diversifier next to stocks and bonds.
- You accept large price swings and little or no income.
- You are comfortable with a fund that holds futures contracts, not companies.
Look elsewhere if
- You want regular income from your holdings.
- You cannot accept large swings in value.
- You want long term growth from a single fund, since commodity prices can move sideways or lower for long stretches.
What COMT holds.
The 10 largest commodity positions inside COMT, as of Nov 9, 2026. Pick a number to see how much of the fund they make up.
The largest positions and the group split are shown below. The fund holds futures contracts, not companies, so the table lists commodities, and each weight is that commodity share of the fund futures exposure rather than a share of net assets.
Weights basis: COMT weights are each commodity's share of futures notional value in the iShares holdings file of Nov 9, 2026.
COMT yield and distributions.
COMT pays distributions once a year in Dec, which makes it an annual payer. The issuer page showed a trailing yield of 4.96% dated Oct 31, 2026. The most recent payment in the log was $1.9271 per share with an ex-date of Dec 16, 2025.
A yield is a snapshot, not a promise. The payment moves each period with the interest the fund earns on its cash and Treasury bills, and some years include capital gains or return of capital that do not repeat. Read the year by year table below before building a plan around a single payment. If you reinvest distributions, the payment still counts as income for tax purposes in a taxable account.

What COMT costs to hold each year.
The expense ratio of 0.48% means the fund keeps about $48 a year for every $10,000 you hold. That cost is taken out of the fund price in small daily amounts, so you never see a bill, but it lowers your return every year. Over ten years on a flat $10,000 the expense ratio adds up to roughly $480, before any growth.
Two other costs sit outside the expense ratio. Trading commissions depend on your brokerage, and most large U.S. brokerages now charge nothing to buy ETFs. The bid and ask spread is a small cost you pay each time you trade, and for the largest funds it is usually tiny.
Expense ratio cost at common amounts
| Amount held | Per month | Per year | Over 10 years, flat | Hypothetical 2.00% fund, per year |
|---|---|---|---|---|
| $1,000 | $0.40 | $4.80 | $48 | $20 |
| $5,000 | $2.00 | $24.00 | $240 | $100 |
| $10,000 | $4.00 | $48.00 | $480 | $200 |
| $25,000 | $10.00 | $120.00 | $1,200 | $500 |
| $50,000 | $20.00 | $240.00 | $2,400 | $1,000 |
| $100,000 | $40.00 | $480.00 | $4,800 | $2,000 |
| $250,000 | $100.00 | $1,200.00 | $12,000 | $5,000 |
Flat estimates at the current expense ratio with no growth and no change in fee. Trading commissions depend on your brokerage and are not included. The 2.00% fund is a hypothetical used for scale.
Where the cost shows up
- Not as a bill. The share price and returns are already lower by the expense ratio.
- Trading cost shows up as the bid and ask spread each time you buy or sell, and as a commission if your broker charges one.
- In a taxable account, income and gains are reported on Form 1099 and taxed in the year they are paid or realised.

What the fund is exposed to.
Commodity group exposure
What the ride can look like.
COMT can lose value, and the period returns from the issuer show the range so far.
- Commodity price risk. The fund falls when the prices of the commodities it holds fall, and those prices can swing sharply.
- Roll cost. When later futures cost more than the nearby one, which is called contango, rolling the contracts costs money and the fund can trail the spot price.
- Little income. The fund pays little or no regular income, so a loss is not cushioned by payouts.
- Concentration. Energy can carry a large share of the weight, so oil and gas prices can drive the result.
- Tax reporting. Income from the futures and cash the fund holds can be taxed as ordinary income, even though you receive a Form 1099 instead of a Schedule K-1.
- Fund specifics. COMT follows the GSCI with a dynamic roll rule, and its roll choice can differ from the index in a given month.
How investors use COMT.
COMT is most often used as a small satellite holding next to stocks and bonds. An investor who owns it is choosing exposure to commodity prices, which can move differently from shares and bonds but not always, and which can fall for long periods.
Compare commodity funds on what they hold and how they roll their futures, not only on the fee. Two funds with similar names can hold quite different mixes, and the comparison pages on this site show the overlap.
Before buying COMT, check four things on the issuer page. First, confirm the expense ratio matches the figure on this page, since fees can change when an issuer cuts costs. Second, confirm the fund is eligible for the account you plan to use. Third, read the latest tax breakdown if you hold it in a taxable account. Fourth, look at the bid and ask spread on the day you trade, since a wide spread is a cost that the expense ratio does not show.
Several comparable funds exist, with expense ratios of DBC at 0.82%, PDBC at 0.59%, GSG at 0.75%, USCI at 1.05%, so weigh cost together with what each fund holds, how it pays and the account you use.
No single fund is right for everyone, and this guide describes the product rather than recommending it. The figures come from the issuer and are dated. Distribution amounts, yields and holdings change, and past returns do not predict future returns. For a decision with large amounts of money, read the prospectus and the shareholder reports, and consider speaking with a licensed adviser about your own situation.

Tax is deferred until you withdraw, and withdrawals are taxed as ordinary income. A 401(k) offers only the funds on its menu, so check whether COMT or a similar fund is in your plan.
COMT is a regulated fund that issues a standard 1099 rather than a Schedule K-1, but income from its futures and cash holdings can be taxed as ordinary income. Your broker reports the amounts on Form 1099 after year end, and those figures are what count on your return.
