Our read on each fund

ETF.net Research

BOATDSonicShares Global Shipping ETF

SEACU.S. Global Sea to Sky Cargo ETF

In short

BOAT The transportation aisle is mostly trucks, rails and planes. BOAT owns the boats: roughly 50 global container, dry bulk and tanker names that haul world trade, held through one passive shipping index.

SEA One ticker for the whole freight chain: container ships, port operators, and air couriers. Fixed-tier weights keep the giant parcel names from swallowing the portfolio, with a 70/30 tilt toward sea over sky.

Stated mandate

BOAT The Fund seeks to track the Solactive Global Shipping Index before fees and expenses using a passive indexing approach.

SEA The Fund seeks to track, before fees and expenses, the performance of the U.S. Global SEA Index.

Why people hold it

  • BOAT Pure-play maritime: container ships, dry bulk carriers and tankers in one ticker, the slice of global trade that truck-and-rail transport funds barely hold.globenewswire.com
  • Rules-based and passive. It tracks the Solactive Global Shipping Index, so the book follows published index rules rather than a manager's hunch.
  • Global by mandate, which matters in an industry where most shipowners list far from New York.globenewswire.com
  • Distributions run on a quarterly cadence, and the portfolio stays compact at roughly 50 names.
  • SEA Owns freight end to end: marine shipping, port and harbor operators, and air freight and courier names, global and including emerging markets.usglobaletfs.com
  • Weights are assigned in fixed tiers (5%, 4% and 2% slots for sea names, 3% for air) rather than by market cap, so one mega-cap courier cannot dominate the book.usglobaletfs.com
  • Reconstitutes and rebalances quarterly, so the roughly 30-stock lineup refreshes with the freight cycle instead of drifting for years.usglobaletfs.com
  • Trading since 2022 and an unusual pairing of ocean and air cargo in a single US-listed fund; it sits in the upper half of its global thematic peer group.usglobaletfs.com

Worth knowing

  • BOAT Costs 0.69% a year, above the transportation-fund median and well above broad options like IYT (0.38%) and XTN (0.35%).
  • Thinly traded and modest in assets, so spreads can widen. Limit orders earn their keep here.
  • Shipping is a freight-rate business: cyclical, concentrated in about 50 names, and bumpier than a diversified transport basket.
  • SEA At 0.60% a year, it runs a touch above the 0.56% median for global thematic funds.
  • A small fund that trades lightly, so spreads can be wider than in large sector ETFs.
  • The index was built by U.S. Global Indices, a subsidiary of the adviser, with Indxx as calculation agent, and about 30 cyclical freight names make for a concentrated ride.usglobaletfs.com
