ACOMCHarbor Active Commodity ETF

PDBCAInvesco Optimum Yield Diversified Commodity Strategy No K-1 ETF

In short

ACOM Most commodity ETFs bolt themselves to a fixed index. This one hands the wheel to Quantix, an ex-Goldman commodities team, to actively trade futures, options and swaps, with the Quantix Commodity Index as the yardstick.

PDBC Broad commodity exposure without the K-1 paperwork. Trading since 2014, PDBC packages a diversified futures basket inside an ordinary fund wrapper and aims to beat its commodity benchmark rather than simply mirror it.

Stated mandate

ACOM The Fund seeks commodity-market exposure through actively managed commodity instruments, including futures, options, over-the-counter swaps, and other commodity-linked derivatives. It normally invests at least 80% of net assets in instruments providing commodity exposure.

PDBC The fund seeks to outperform the excess-return version of its benchmark through a diversified commodity strategy.

Why people hold it

  • ACOM Genuinely active, not index-plus: the subadviser picks and sizes futures, options and OTC swaps across commodity markets rather than following set index weights.nasdaqtrader.comharborcapital.com
  • The bench behind it: Quantix is led by CIO Don Casturo, formerly Goldman Sachs' global commodities COO, and the same shop runs Harbor's index-based commodity ETF and built the Quantix Commodity Index.harborcapital.comharborcapital.com 2
  • Built as a 1940 Act fund, with commodity derivatives routed through a wholly owned Cayman subsidiary, the standard plumbing for keeping this exposure inside fund tax rules.sec.govsec.gov 2
  • The mandate has guardrails: at least 80% of net assets must sit in commodity-exposure instruments, so it stays a commodity fund however the manager shifts between markets.nasdaqtrader.com
  • PDBC The K-1 dodge is right there in the name. It is built as a 1940 Act fund, not a commodity partnership.invesco.com
  • 0.74% a year, below the typical fee among commodity futures funds.
  • A multi-billion-dollar fund and one of the busiest tickers in the commodity aisle, which tends to show up as tight spreads for buyers and sellers.
  • Live since 2014 and one of the strongest implementations in its commodity futures peer group.

Worth knowing

  • ACOM Active discretion carries a price: 0.93% a year, above the median for futures-based commodity funds, several of which run cheaper index strategies (PDBC at 0.74%).
  • It launched in 2026, so there is no long public record for the strategy in this wrapper, and it remains small and thinly traded next to the category's established names.harborcapital.com
  • Returns come from a derivatives book, not a coupon: commodity futures and swaps can move sharply, and the fund has not been paying distributions.harborcapital.com
  • PDBC Commodities swing. Energy, metals and crops can move hard in both directions, and this basket rides every one of those moves.
  • The mandate is to beat the benchmark, not hug it, so results can diverge from the index it measures itself against.invesco.com
  • Payouts are lumpy by design: distributions land annually or semiannually, not on a monthly drip.
