How to Build an Efficient Core With ETFs

In today’s environment, where geopolitical risk and macro uncertainty are converging, gold is attracting renewed interest. But traditionally, adding it has required trimming core exposures. A growing set of efficient core ETF strategies is starting to change that equation, offering a way to add gold without sacrificing equities or fixed income.That shift was a key focus of The Efficient Core: How to Set Your Portfolio Up for Success in Today’s Environment, hosted by VettaFi and WisdomTree’s Andrew Okrongly, director, model portfolios and Jeff Weniger, head of equity strategy.Key Takeaways Solving the “Portfolio Paradox”: Traditional diversification usually requires selling stocks or bonds to fund alternatives, but capital efficiency allows advisors to “stack” exposures, gaining assets like gold without sacrificing core growth. Macro Stability Over Hyperbole: Experts view the current inflation landscape as a “middle ground” tug-of-war between rising oil prices and an “ice-cold” housing market, noting that the consumer remains resilient due to significant wage growth since 2008. The Structural Advantage of “90/60”: Using ETFs that invest 90% in equities and use 10% to collateralize 60% in futures enables investors to put $150 of notional exposure to work for every $100 invested, effectively “expanding the garage” for diversifiers. A Middle Ground Inflation RegimeInflation is no longer swinging between extremes — it’s settling into a middle ground, as Weniger put it. Volatility in energy remains a risk, but it’s being offset by a sharply cooler housing market. Weniger described conditions there as “ice cold,” with disinflationary pressure helping to balance out broader price trends. At the same time, consumers are in a stronger position than in past cycles, supported by relatively firm wage growth. That balance is helping sustain a constructive outlook for equities, with earnings strength continuing to support the case for the S&P 500 into 2026.

Gold is a clear example of that trade-off. It can act as effective ballast during drawdowns, but traditional allocations typically come at the expense of core equity or fixed income exposure. That creates an inherent tension — diversifiers tend to feel most painful when markets are strong, exactly when sticking with them is most difficult. As Kirsten Chang, senior research analyst at VettaFi pointed out, maintaining those positions through periods of equity outperformance demands real conviction, particularly when growth assets are leading the way.Capital Efficiency as a Structural SolutionAccording to Okromley capital efficiency is a way to reduce that trade-off altogether. Using ETF-based structures, advisors can “stack” exposures rather than choosing between them. WisdomTree’s efficient core suite — including the WisdomTree U.S. Efficient Core Fund (NTSX C+) and the WisdomTree Efficient Gold Plus Equity Strategy (GDE ) — employs a 90/60 framework designed to optimize portfolio construction. The structure allocates the majority of capital to core equity exposure. Meanwhile, it uses a smaller allocation to collateralize a futures overlay in either Treasuries or gold. The result is a portfolio that maintains full market participation while layering in additional sources of diversification. Expanding the Portfolio GarageWeniger’s framing is straightforward: Expand the “garage,” don’t replace it. Capital-efficient core exposures can create space for diversifiers without sacrificing equity participation. That shift reframes the problem. Access to diversification isn’t the issue — implementation is. Looking ahead to the second half of 2026, portfolio construction is becoming less about trade-offs and more about structure. That allows advisors to pursue diversification without stepping away from growth. For more news, information, and analysis, visit the Modern Alpha Content Hub.
