COMT vs SDMF

COMTBiShares GSCI Commodity Dynamic Roll Strategy ETF

SDMFBSimplify DBi CTA Managed Futures Index ETF

In short

COMT The broad commodity fund that skips the Bloomberg crowd. COMT tracks the S&P GSCI Dynamic Roll, weighting commodities by world production instead of sector caps, with a roll method built to blunt the drag of contango.

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

COMT The fund seeks to track the S&P GSCI Dynamic Roll (USD) Total Return Index, which represents a broad commodity exposure with enhanced roll selection across sectors.

SDMF The Fund seeks long-term capital appreciation.

Why people hold it

• COMT 0.48% net of a waiver through February 28, 2029 (0.49% gross), which sits below the median fee in the broad commodity futures category.ishares.com
• Weighted by world production rather than sector caps, so it leans toward what the world pumps and digs most, a different mix from Bloomberg-index rivals BCI and CMDY.spglobal.com
• Rather than mechanically rolling front-month futures, the index uses an enhanced roll selection designed to alleviate the negative impact of rolling into contango.spglobal.comspglobal.com 2
• Listed in 2014, with more than a decade of live history and over a billion dollars in assets behind it. Not a thin, untested launch.

• 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

• COMT This is the full-energy version of the GSCI, not the reduced-energy variant, so energy drives much of the move. Commodity futures are volatile, and the ride here reflects that.spglobal.com
• Below the median, but not the cheap seat: COMB charges 0.25% and BCI 0.26%, neither relying on a waiver, for their own broad commodity futures baskets.
• The commodity exposure sits in a wholly owned Cayman subsidiary run by the same manager. That subsidiary is not registered under the 1940 Act.ishares.comsec.gov

• 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.
