WisdomTree U.S. Efficient Core Fund (NTSX) seeks to provide leveraged exposure to U.S. equities while maintaining Treasury bond exposure through an innovative 90/60 allocation strategy. This efficient core approach combines 90% exposure to the U.S. stock market with 60% exposure to intermediate-term Treasury bonds, totaling 150% gross exposure within a single fund.
How It Works
NTSX uses derivatives and direct holdings to achieve its 90/60 allocation, typically holding equity index futures contracts and physical Treasury bonds. The fund maintains approximately 90% notional exposure to broad U.S. equity markets and 60% to intermediate-term U.S. Treasury securities. This leveraged approach uses the bond allocation as collateral for equity futures positions, rebalancing monthly to maintain target allocations. The strategy aims to capture equity upside while providing some downside protection through Treasury exposure.
Key Features
- Unique 90/60 allocation provides 150% total market exposure while maintaining diversification across asset classes within single fund
- Uses Treasury bonds as collateral for equity futures, creating capital efficiency unavailable in traditional stock/bond portfolios
- Monthly rebalancing maintains consistent risk profile and captures rebalancing premium between uncorrelated asset classes
Risks
- This ETF can lose value when both stocks and bonds decline simultaneously, as occurred during 2022 inflation periods, potentially amplifying losses beyond traditional portfolios
- Derivatives exposure creates counterparty risk and potential tracking error versus underlying indices, especially during market stress when futures may trade at premiums
- Leveraged structure means volatility exceeds traditional 60/40 portfolios, with potential for 20-30% annual swings during normal market cycles
Who Should Own This
Best suited as a core holding (30-50% of total portfolio) for moderate-to-aggressive investors with 5+ year time horizons seeking enhanced returns from traditional stock/bond allocation. Requires medium-high risk tolerance due to leveraged exposure and correlation breakdown risk. Ideal for investors wanting simplified portfolio construction with built-in rebalancing discipline.
