GSGCiShares S&P GSCI Commodity-Indexed Trust

SDMFBSimplify DBi CTA Managed Futures Index ETF

In short

GSG The old-guard commodity trade. Since 2006, GSG has tracked the S&P GSCI, a fully collateralized basket of commodity futures, while most of the newer competition is built on Bloomberg indexes and roll-tweaking overlays.

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

GSG The fund seeks to track a fully collateralized index representing a diversified group of commodity futures.

SDMF The Fund seeks long-term capital appreciation.

Why people hold it

  • GSG Tracks the S&P GSCI Total Return Index: a diversified, fully collateralized futures basket, with collateral interest built into the index rather than paid out.ishares.com
  • Live since 2006, so its record spans more than one commodity boom and bust.
  • A different engine from the pack: peers like BCI, BCD and CMDY run Bloomberg commodity indexes, while GSG stays with the S&P GSCI.
  • Actively traded, so getting in and out is generally straightforward.
  • 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

  • GSG The 0.75% fee sits above the broad-commodity norm: BCI charges 0.26% and CMDY 0.29% for a similar all-in-one basket.
  • Commodity futures swing hard, and this one sits among the more volatile choices even inside its own category.
  • No distributions: collateral interest shows up inside the total-return index instead of arriving as income.
  • 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.
