If leveraged long-term holding has a textbook case, it's 2× the S&P 500: a low-volatility, long-uptrending index where decay stays comparatively tame — the well-known leveraged buy-and-hold strategies are built around this trade. This page runs SSO's actual parameters.
Compare how much of a leveraged ETF to hold versus its plain 1× index — five splits from all-leverage to all-index, rebalanced monthly, quarterly or yearly. See CAGR, drawdown and risk-adjusted return, volatility decay included.
Underlying index
Leverage & rebalancing
The tool compares five fixed splits — 100/0, 75/25, 50/50, 25/75, 0/100 — of this leveraged fund and its plain 1× index, all rebalanced yearly.
Capital & horizon
Strategy comparison
Each column is a split between the 2× fund and its plain 1× index (leveraged % / index %), rebalanced yearly. Effective exposure = leveraged share × 2 + index share × 1 (shown under each split); 0/100 is the plain 1× index.
Median growth by strategy
Based on 500 simulated paths with daily-reset leverage. A simplified lognormal model, not a forecast: real markets have fatter tails, jumps, and shifting volatility, all of which hit leverage harder. Treat as rough odds, not promises.
Under the prefilled assumptions, going 100% SSO for 10 years lands at a median value of about 663K (≈20.8% annualised) — with a median max drawdown of −49.7% along the way. A 50/50 blend with the plain 1× index comes to about 527K with the drawdown cut to −38.4%; skipping leverage entirely (pure 1× index) gives about 394K at −25.3%.
Monte Carlo simulation seeded with the underlying index's 10-year CAGR and estimated volatility. That decade was a strong bull run — shave a few points off the return and look again.
Decay ∝ leverage² × volatility². The S&P 500 runs ~16% annual volatility, a notch below the Nasdaq, so at the same 2× SSO decays visibly less than QLD — *what* you lever matters as much as *how much*. Low-volatility underlyings are the ones that can carry leverage long term. When you compare columns, remember SSO's median advantage rests on the S&P trending up. Swap the prefilled 14.7% (last decade) for a long-run 8–10% and the edge shrinks but usually survives — that resilience is what separates it from higher-vol underlyings.
Good fit: running broad-market exposure at ~1.3–1.7× over a long horizon with disciplined rebalancing; also a common building block in leveraged stock/bond mixes.
Watch out: SSO fell roughly 80% in 2008 and nearly halved in 2022. Tame decay is not tame drawdown — deep drawdowns come from the index itself falling for weeks, and no leverage factor escapes that.
This is a free side project I built in my spare time. If it saved you time or helped you think through a decision, buying me a coffee keeps the lights on!
How much of a leveraged ETF should you hold versus the plain index? Compare 100/0, 75/25, 50/50, 25/75 and 0/100 splits of a 2×/3× fund and its 1× index — all rebalanced yearly — on CAGR, max drawdown, Sharpe and Calmar.
