CMDYAiShares Bloomberg Roll Select Commodity Strategy ETF

COMBAGraniteShares Bloomberg Commodity Broad Strategy No K-1 ETF

In short

CMDY Commodities without the worst of the futures math. CMDY tracks the Roll Select version of the Bloomberg commodity index, where contract choice is written into the rules to ease rolling costs, and charges 0.29% to do it.

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.

Stated mandate

CMDY The fund seeks to track an index representing a broad range of commodity exposures, using enhanced roll selection on a total-return basis.

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

Why people hold it

  • CMDY The name is the strategy. Enhanced roll selection is baked into the index it tracks, so which futures contract to hold is a rule, not an afterthought.
  • 0.29% a year sits in the low-fee tier of broad commodity funds, next to BCI, CERY and BCD, and well under what the category typically charges.
  • One ticker, a broad basket of roughly 60 futures positions, run on a total-return basis that counts collateral income alongside commodity price moves.
  • Live since 2018 under the iShares roof, and one of the stronger implementations in its broad-basket commodity peer group.
  • 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.

Worth knowing

  • CMDY Moderately traded rather than a volume monster. Spreads can run wider than the mega-cap index funds, which shows up most on large or hurried orders.
  • It is structured as a commodity pool, not a plain stock fund, so the tax paperwork and reporting work differently. Check the details before filing season.
  • Distributions land annually or semiannually, not monthly, and the roll rule addresses futures mechanics only. Commodity prices still swing hard on their own.
  • 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
