COMB vs KRBN

COMBBGraniteShares Bloomberg Commodity Broad Strategy No K-1 ETF

KRBNFKraneShares Global Carbon Strategy ETF

In short

COMB The cheapest ticket in the K-1-free commodity aisle: 0.25% for a broad basket of energy, metals, grain and livestock futures, wrapped so your tax packet is a Form 1099 instead of a Schedule K-1.

KRBN Most commodity funds hold oil, copper and corn. KRBN holds the right to pollute: futures on emission allowances from major cap-and-trade programs worldwide, bundled into one index-tracking fund.

Stated mandate

COMB The fund seeks long-term capital appreciation mainly through exposure to commodity futures markets.

KRBN The Fund seeks to track the S&P Global Carbon Credit Index, which consists of futures contracts on emission allowances issued under various cap-and-trade regulatory regimes.

Why people hold it

• COMB At 0.25%, the lowest fee among the category's top-scoring broad commodity funds (BCI 0.26%, CERY 0.28%, CMDY 0.29%, BCD 0.30%) and below the category median.
• Gains its futures exposure through a wholly owned Cayman subsidiary, so the fund is designed to be taxed like a conventional fund and issue a 1099, not a K-1.sec.gov
• Benchmarked to the Bloomberg Commodity Index: about 30 positions across energy, metals, agriculture and livestock, with index rules capping any commodity group at 33%.bbhub.io
• Live since 2017, long enough to have run through a full commodity boom and bust, and it sits in the top quartile of its peer group.

• KRBN Buys carbon itself. The portfolio is futures on emission allowances issued under cap-and-trade regimes, a price shaped by regulators capping supply rather than by drilling or harvests.kraneshares.com
• Global by design. The S&P Global Carbon Credit Index spans multiple regulatory regimes, so no single government's rulebook sets the whole portfolio.
• Running since 2020, and rules-based: an index defines what it holds, in an ETF wrapper instead of a futures account with margin calls.

Worth knowing

• COMB Thinly traded next to the category's household names, so spreads can widen. Matters most on bigger orders.
• Returns ride the futures curve, not spot prices. Rolling contracts forward can add to or subtract from the move in a commodity's headline price.graniteshares.com
• Actively managed rather than a strict index clone, with Treasury bills as collateral and cash paid out annually or semiannually, not monthly.graniteshares.com

• KRBN The 0.91% expense ratio sits well above the diversified commodity baskets it's grouped with, such as BCI and CMDY. Niche exposure, niche price.
• Thinly traded next to the big broad-commodity funds, so spreads can run wider and sizable orders deserve more care at the screen.
• One theme, set by policy. Allowance prices turn on regulatory decisions, so this can move on its own schedule while the rest of the commodity complex sits still.
