Leveraged ETF Compounding and Positive Skew in Simulated Returns

Summary

The document models daily-reset two-times long and short leveraged ETF returns by multiplying each day’s underlying return and compounding the resulting daily values. It includes annual management, spread, and commission costs, then uses Gaussian daily return simulations to examine one-year payoff distributions and compares ETF returns with index drift. It also considers holding long and short products together.

The central mechanism is compounding: equal-sized daily gains and losses do not offset symmetrically, which can create a positively skewed payoff distribution even when simulated underlying returns have zero average drift. The analysis is illustrative rather than empirical. Its conclusions depend on assumed return distributions, volatility, costs, and simplified product mechanics; the supplied excerpt does not provide a completed discussion of the plotted comparisons or establish a reliable investment strategy. Leveraged ETFs can have path-dependent outcomes, and the modeled skew does not remove the possibility of losses.

Key ideas

• Daily-reset leveraged ETF returns compound across the sequence of underlying returns.
• Compounding can make equal daily percentage gains and losses asymmetric in cumulative value.
• The document uses Gaussian simulations to study one-year payoff distributions and drift sensitivity.
• Management, trading, and commission costs reduce modeled returns.
• The results depend on simplifying assumptions and do not establish that the approach is profitable in practice.
