The 60/40 stock-bond portfolio stays a widely used benchmark for long-term asset allocation despite ongoing debates about its optimality (Pham et al., 2025). However, for a lot of households, the challenge lies not within the framework itself, but in the quantity of capital required to implement it. Limited investable assets, the will to avoid explicit borrowing, significant exposure to residential real estate, and the necessity to keep up money reserves often limit the power to completely fund a standard allocation.
Leveraged ETFs offer an alternate. Rather than increasing risk, they allow households to realize desired risk exposure with less capital employed, improving liquidity management, property leverage and broader balance sheet constraints. As shown below, leveraged ETFs combined with money holdings can approximate the danger characteristics of a standard 60/40 portfolio while avoiding margin accounts, personal lines of credit, or other types of household-level leverage.
By separating market exposure from capital commitment, this framework preserves liquidity and financial flexibility while maintaining a well-known asset allocation profile.
Motivation: Asset allocation on the household level
For most retail investors, portfolio construction occurs throughout the constraints of the household balance sheet, where real estate exposure, mortgage debt, employment income risk, and liquidity needs determine viable investment decisions. Many households are already structurally indebted as a result of real estate. Over the past few many years, rising property values ​​in developed economies have led to increases in net price while concentrating risk on illiquid assets. As a result, investors often chubby real assets and underweight liquid financial capital.
Traditional forms of monetary leverage introduce additional risks that many retail investors are unwilling or unable to bear, including margin calls on drawdowns, fixed repayment obligations on credit lines, and behavioral constraints that may result in ill-timed de-risking or forced liquidation in times of increased volatility.
In contrast, leveraged ETFs – whose leverage is on the fund level reasonably than on the household balance sheet – when used thoughtfully, allow investors to separate market exposure from capital deployment, leading to greater flexibility in household portfolio construction.
Methodology and portfolio construction
The following evaluation evaluates whether a portfolio consisting of leveraged stock and bond ETFs combined with money can approximate the return and volatility characteristics of a standard 60/40 stock-bond portfolio without counting on margins, personal loans, or other types of household-level leverage[1].
Benchmark and instruments
The goal allocation is a standard 60/40 portfolio consisting of:
- 60% exposure to the S&P 500
- 40% exposure to US Treasuries, represented by a maturity of roughly seven years
To implement these exposures, the next instruments are utilized in the evaluation:
- A hypothetical ETF that gives thrice the every day return of the S&P 500
- A hypothetical ETF offering 3x the every day return of long-dated U.S. Treasury bonds (20+ yr maturity; duration ≈16) with position size scaled to realize targeted portfolio duration
- Cash worthy of the nightly rate
Although the underlying maturity of the leveraged treasury instrument is longer, its portfolio weight is scaled such that the resulting effective duration of the combined portfolio is roughly equal to the seven-year goal.
Cost and financing assumptions
To higher estimate real-world performance, the next assumptions are considered:
- Annual administrative expense ratio (MER): 1%
- Borrowing costs at fund level: overnight rate + 50 basis points
- Cash generates the overnight price
Portfolio construction process
Instead of setting nominal portfolio weights, the strategy goals for stable effective market exposures:
- An equity exposure comparable to roughly 60% of the S&P 500
- A treasury term of roughly seven years
At the top of every month, the portfolio weights are adjusted to keep up these risk targets. Stock and bond ETF allocations are scaled to realize desired equity exposure and portfolio duration, with remaining capital allocated to money. Monthly rebalancing is required to offset risk drift resulting from every day rebalancing of leveraged ETFs.
Due to the every day reset nature of leveraged ETFs, effective exposures fluctuate over time, requiring periodic rebalancing. Over the sample period, the resulting portfolio weight is roughly 20% within the Leveraged Equity ETF, 15% within the Leveraged Treasury ETF, and 65% in money.
Observed results and comparison with 60/40
The strategy is retested using monthly data from December 31, 2022 to December 31, 2024 and evaluated against a standard 60/40 benchmark (Table 1). Over the sample period, the leveraged ETF plus money portfolio delivers cumulative returns broadly comparable to the benchmark. More importantly, the realized volatility is precisely the identical as the standard 60/40 portfolio, suggesting that the exposure targeting framework is effective in replicating first-order risk characteristics.
Table 1 (Summary Statistics)
Track differences
Periods of divergence between the 2 portfolios are primarily attributable to:
- Daily leverage reset effects in volatile markets
- Embedded funding costs in leveraged ETFs
- Monthly rebalance frequency
- The prevailing money return environment
These aspects lead to tracking error but don’t significantly change the general risk profile of the portfolio.

Distributional effects
While mean returns and volatility are comparable, the leveraged portfolio has broader values ​​in comparison with the standard 60/40 portfolio. This reflects the non-linear return dynamics created by every day leveraged instruments, particularly during times of high volatility.

Practical risks and limitations
While the framework illustrates a capital efficient approach to risk management, it involves vital trade-offs that require careful consideration. Leveraged ETFs are designed to duplicate multiples of index returns. For longer holding periods, their performance becomes path dependent as a result of every day leverage resets, with volatility resistance increasing non-linearly as leverage increases (Pessina and Whaley, 2021).
In addition, the evaluation relies on hypothetical leveraged ETFs and the actual performance of actual products may differ from the modeled results, particularly during times of stressed market conditions. Finally, although average volatility could also be consistent with a standard 60/40 portfolio, using leverage increases tail risk, implying the next probability of maximum outcomes.

Capital efficiency as portfolio design
Leveraged ETFs are sometimes dismissed as unsuitable for long-term investors as a result of volatility drag and path dependency. This evaluation shows that leveraged ETFs, when utilized in a disciplined and risk-managed framework, can as an alternative act as tools to enhance capital efficiency reasonably than increase portfolio risk. By replicating the danger characteristics of a standard 60/40 stock-bond portfolio with significantly less capital invested, this approach allows households to preserve liquidity and mitigate concentration as a result of exposure to residential real estate. While careful implementation and ongoing risk awareness remain essential, the framework highlights an underappreciated use of leverage in modern household portfolio construction.
