Wall Street has an answer to 60/40 — this ETF crams 90/60 into the same dollar: One Big Investment Idea

In the evolving world of ETFs, Wall Street is crafting innovative products to enhance market outcomes beyond traditional 60/40 allocations. WisdomTree US Efficient Core Fund (NTSX) exemplifies this trend by investing around 90% in US stocks and leveraging Treasury futures to add 60% bond exposure. This means each $100 invested yields approximately $150 of market exposure, blending stocks and Treasurys without requiring full capital commitment.

The rationale behind capital-efficient ETFs is to maximize returns without sacrificing valuable portfolio capacity to bonds. For example, instead of setting aside $40 of a $100 portfolio for bonds, these funds use derivatives like futures to layer additional market exposure. This approach was pioneered by NTSX in 2018 and has since gained traction as investors seek more adaptive investment strategies.

One emerging product in this space is the autocallable ETF, which aims to generate high income while the market remains strong, but may incur losses if the market declines significantly. Autocallable ETFs have been attracting attention, with holdings nearing $4 billion, approaching the scale of the older capital-efficient ETFs. However, the downside risk is not eliminated; if the market dips too much, investors face potential losses akin to owning stocks directly.

The appeal of these capital-efficient ETFs lies in their ability to engineer different market results, such as cushioning losses or magnifying gains, but they come with trade-offs. For instance, an autocallable ETF may pay high income at the cost of limited upside during market downturns. Investors should carefully evaluate the underlying exposure and how it behaves under market stress before investing.
