GSUS vs STXK

GSUSAGoldman Sachs MarketBeta U.S. Equity ETF

STXKCStrive Small-Cap ETF

In short

GSUS Goldman's no-frills core: one index covering the largest 85% of the US market by free float, about 400 large and mid caps, at 0.07% net of a waiver through December 29, 2026.

STXK Strive's swing at small caps: one ticker for roughly 600 smaller U.S. companies, tracking Bloomberg's US 2000 index for 0.18% a year, a hair under its peer group's median fee.

Stated mandate

GSUS The Fund seeks to track, before fees and expenses, the performance of its underlying U.S. large- and mid-cap equity index.

STXK The Fund seeks to track the investment results of the Bloomberg US 2000 Index, representing U.S. small- and mid-capitalization equities.

Why people hold it

• GSUS Costs 0.07% net of a waiver through December 29, 2026 (0.09% gross), undercutting Goldman's own GUSA at 0.10% and the Alpha Architect pair, AAEQ and AAUA, at 0.09% each.gs.com
• Nothing clever under the hood: it holds the index's stocks at free-float market-cap weights, and it has tracked that index very closely, among the tightest in its peer group.sec.gov
• A billion-dollar-plus fund that trades in reasonable volume, with a quarterly distribution schedule.

• STXK Charges 0.18% a year, under the 0.20% median for its peer group and well below the 0.30% on Janus Henderson's small/mid growth fund, JSMD.
• Roughly 600 small- and mid-cap U.S. stocks in one line item, so the outcome rides on the smaller end of the market rather than a handful of names.
• Simple, legible job: track the Bloomberg US 2000 and stay in U.S. equities. On mandate fidelity it lands in the upper half of its peer group.
• Standard 1940 Act fund structure with quarterly distributions. No leverage, no derivatives wrapper, no options overlay to decode.

Worth knowing

• GSUS The index stops at roughly the largest 85% of US free float, so small caps sit outside it. Not a total-market holding.sec.gov
• The 0.07% sits near the category's typical fee, not at the floor: ILCB charges 0.03% with no waiver attached. And GSUS reverts to 0.09% if its waiver lapses on December 29, 2026.
• Free-float weighting means the biggest US companies dominate the top of the portfolio, by design.sec.gov

• STXK Thinly traded, so bid/ask spreads can run wider than on the household-name small-cap funds.
• Small and mid caps move harder in both directions than large-cap benchmarks. Bumpier ride is the price of admission here.
• Launched in 2022 and still modest in size, so the track record is short next to the decades-old small-cap index funds.
