Leveraged ETFs: High Rewards, High Risks

This return is more than 10 times higher than that achieved by a regular S&P 500 ETF over the same period, highlighting the potential for significant gains through leverage. While leverage can be a valid tool in asset allocation, its use also poses substantial risks for investors.

Leverage amplifies the market exposure an investor receives for each dollar invested in an asset. Leveraged ETFs are one of the most direct ways to gain access to this amplification.

For instance, a 2x leveraged ETF converts a $1,000 investment into $2,000 worth of daily index returns. This mechanism significantly increases both volatility and overall returns, depending on the associated leverage costs and the performance of the underlying asset.

Young individuals typically possess substantial human capital, representing their future earnings potential, yet have limited financial assets. This scenario leads to an overall asset allocation heavily concentrated in safe assets through human capital, with minimal exposure to riskier assets like stocks.

Academic work by Paul Samuelson in 1969 and Robert Merton in 1971, later refined in 1992, posits that if human capital functions as a safe, bond-like asset, then borrowing money to invest in stocks becomes a rational strategy.

Additionally, labor flexibility, such as the ability to work overtime during periods of market downturns, further supports the rationale for employing higher leverage. The optimal level of leverage is also influenced by how an individual's income correlates with the stock market.

Evidence also shows that many high-income households experience declines in wage and business incomes simultaneously with stock market downturns.

In these adverse times, these households often resort to selling liquid assets, including their stock holdings, to cover income shortfalls for fixed expenses like mortgages and daycare. Selling stocks after a market decline can be an unfavorable financial outcome, suggesting the 'safe human capital' premise requires careful consideration before being applied in practice.

The 2013 paper, 'Diversification Across Time,' advocates for the use of leverage by young investors. Practical strategies often involve employing 2x leverage early in one's investment journey.

The recommended approach then advises a gradual reduction in the degree of leverage as an individual approaches retirement, aligning investment risk with life stage.

However, the non-leveraged constant allocation typically exhibits a higher standard deviation of retirement wealth.

Academic models frequently assume human capital as a safe, bond-like asset, yet real-world conditions often introduce volatility to this assumption. This divergence underscores the complexities in applying theoretical models to practical investment strategies.

Predicting future returns and their variance, however, makes constant relative risk aversion a highly uncertain metric.

Naturally, investors with a high degree of risk aversion will require lower optimal equity allocations, which in turn reduces their need to use leverage to achieve their target allocation. This highlights the subjective nature of risk tolerance in investment decisions.

A comprehensive model involving a million simulations has been used to identify optimal life cycle asset allocation strategies by explicitly incorporating labor income risk. This model provides insights into practical leverage application.

Borrowing at 1.4% above the risk-free rate allows households to optimally apply 2x leverage early in life before gradually decreasing the ratio over time. The optimal portfolio under these conditions includes approximately 34% domestic stocks and 66% international stocks.

Leverage introduces significant risks, including the potential for total wipeouts of financial assets, which can impose severe psychological burdens on investors. Major market crises have triggered declines of nearly 80% in 2x and 3x leveraged S&P 500 ETFs.

Financial journalist Jason Zweig remarked that only individuals capable of living in a 'sensory deprivation tank' should consider holding leveraged funds for the long term. This underscores the extreme emotional resilience required.

Furthermore, factors such as volatility drag, management fees, and financing costs contribute to the long-term underperformance of leveraged ETFs, diminishing their overall returns for investors over extended periods.

Leveraged ETFs provide exposure to underlying assets by employing swaps and/or futures within an ETF structure. This setup offers several benefits to investors, including convenience, simplicity, and non-recourse protection.

Non-recourse means that investors cannot lose more than their initial investment, a significant advantage over traditional margin trading. This structure also relieves individual investors of the burden of managing leverage ratios and margin calls.

The mechanics of these funds require them to buy more stock when the index rises to maintain leverage and sell when it falls. Mathematically, the cost of volatility is insensitive to rebalancing frequency if returns exhibit no serial correlation.

More frequent rebalancing can be beneficial if there is positive serial correlation in returns but detrimental if the correlation is negative, influencing the overall performance outcome.

A 2026 working paper on single-stock leveraged ETFs explains that daily resets can create costs relative to benchmarks due to specific return paths. However, this does not universally lead to performance destruction.

A 2022 study found that leveraged ETFs frequently outperformed static margin portfolios during periods of extreme bull and bear markets, while also offering reduced downside risk. Another 2025 paper concluded that long leveraged index ETFs closely track non-rebalanced portfolios for holding periods up to a year.

Divergence in return paths makes significant underperformance statistically less likely than significant outperformance, challenging older notions about the inherent flaws of these instruments. The author concludes that daily leverage resets are not the problem they have historically been made out to be.

A 2026 working paper identifies five key performance drivers: volatility drag, fees, financing costs, product launch timing, and market timing.

Volatility drag is a genuine concern, and leverage inherently increases it by amplifying volatility.

An increase in volatility creates a larger divergence between the leveraged return and the underlying asset's return.

For example, a 2x leveraged ETF experiencing 5% daily volatility would require nearly a 100% annual return to simply match the performance of its underlying asset. Furthermore, financing costs impose an additional burden, further increasing the break-even return required for investors.

Morningstar research highlights that investors in single-stock leveraged ETFs have a higher probability of losing over 75% of their investment than outperforming the underlying stock. Since inception, 19% of these single stock ETFs have experienced losses exceeding 75%.

The total costs associated with 2x leveraged single stock ETFs can approach nearly 12%, making it exceptionally challenging for investors to achieve positive returns. These high costs severely impact long-term performance.

For instance, the embedded financing rate on a swap contract, a common component of leveraged products, is typically not reflected in the expense ratio.

For 2x leveraged index ETFs, the total ownership costs can surpass 5% annually, based on current risk-free rates. These hidden costs can significantly erode investor returns, making it crucial to look beyond advertised expense ratios.

A 2026 paper argues that daily rebalancing in leveraged ETFs produces convex payoffs rather than an inherent destruction of value. This challenges the long-held belief about their value erosion.

The author contends that the 'demonization' of leveraged and inverse equity index ETFs, particularly the false accusation of value erosion via volatility decay, is a significant disservice to investors. Investors can strategically combine leveraged and regular index ETFs to achieve moderate leverage levels, such as 1.25x.

Volatility itself, rather than the leverage reset mechanism, causes volatility drag.

Despite this re-evaluation for diversified index ETFs, single stock leveraged ETFs continue to present considerable challenges and remain problematic for investors due to their heightened risks and costs compared to their diversified counterparts.
