NTSI — WisdomTree International Efficient Core Fund

NTSI extends the 90/60 framework to developed ex-U.S. equities with a Treasury futures overlay to improve capital efficiency.

Equity Efficiency:BCapital Efficiency grades how well this ETF delivers equity-side returns relative to the capital and beta it uses, with SPY as the B baseline. Leveraged ETFs score higher when they free up capital for an alpha sleeve. Long/short and factor ETFs are graded on excess return versus SPY, net of costs. NTSI targets roughly 90% developed ex-U.S. equity exposure as the capital sleeve. The grade scores that equity component versus SPY under the site framework.Alpha Efficiency:DAlpha Efficiency grades the non-equity sleeve of this stacked ETF on return above its borrowing cost: that's the true hurdle for a futures overlay. A sleeve that only matches its financing cost adds no value; grades above B mean the overlay is genuinely earning its keep. The second sleeve is Treasury futures notional (~60% target) layered through derivatives. The alpha grade scores return above hurdle for that non-equity sleeve.Stacked Efficiency:CStacked Efficiency blends Capital- and Alpha-bucket grades using the configured sleeve weights (60% capital / 40% alpha).

Strategy

The equity sleeve focuses on developed markets outside the U.S., while U.S. Treasury futures provide the added duration sleeve. Currency and regional factor moves can dominate short-run performance.

Compared with holding separate international equity and bond funds, NTSI concentrates implementation risk in one wrapper but can simplify sleeve sizing inside multi-asset portfolios.

Manager and Issuer Pedigree

WisdomTree built its brand on fundamentally weighted and capital-efficient ETFs well before many copycat implementations. The same derivatives-and-collateral framework underpins its Efficient Core and related stacked sleeves.

WisdomTree has reported roughly $143B+ in global ETP and tokenized AUM (late-2025 disclosures), giving institutional futures and collateral infrastructure while still operating as a specialist versus the largest index houses.

Outperformance

Outperforms when developed ex-U.S. equities lead and Treasury duration is stable-to-positive, particularly when non-U.S. cyclicals participate without a bond selloff.

Underperforms when international equities lag and U.S. rates reset higher, because both the equity and duration sleeves can be pressured together.
