SDMFBSimplify DBi CTA Managed Futures Index 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.

SDMF Managed futures without the hedge fund bill. SDMF tracks an index built to replicate what CTA trend funds are actually doing, using a short list of liquid futures markets, for 0.35% a year.

Stated mandate

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

SDMF The Fund seeks long-term capital appreciation.

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.
  • SDMF Charges 0.35%, roughly half the typical fee among futures-strategy funds in its group. Cheap shelf space for a strategy that usually arrives with hedge fund pricing.
  • Rules over hunches: it follows the DBi CTA Managed Futures Index and its advertised 10-factor replication approach, not a trader's discretion.simplify.us
  • Its cohort is mostly long-only commodity baskets (BCI, CMDY). This one is a managed futures strategy, which can lean either direction across futures markets.
  • Ordinary 1940 Act ETF plumbing: daily pricing, intraday trading, no lockup or subscription paperwork.

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
  • SDMF Launched in 2026, so there is no long record here and the risk picture rests on limited history.
  • A small fund that has traded lightly since launch, so spreads can run wider than the big commodity index names in its category.
  • The stated goal is long-term capital appreciation, and payouts come once or twice a year at most. Not built as an income stream.
