Bullish on semis but scared off by SOXL's −90%? USD (ProShares Ultra Semiconductors) runs 2× on the Dow Jones U.S. Semiconductors Index. Semiconductors already swing at ~30% annual volatility, so 2× puts the path volatility in 3×-broad-market territory — this page runs the real parameters to show roughly where the leverage ceiling for semis sits.
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% USD for 10 years lands at a median value of about 7.9M (≈54.7% annualised) — with a median max drawdown of −69.4% along the way. A 50/50 blend with the plain 1× index comes to about 4.4M with the drawdown cut to −56.5%; skipping leverage entirely (pure 1× index) gives about 1.9M at −40.4%.
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.
Same underlying, but 2× carries just 44% of 3×'s decay (decay ∝ leverage²), and its drawdowns need far smaller rallies to recover — that's USD's real edge over SOXL. Mind the absolute numbers though: 30% volatility × 2 ≈ 60% path volatility, the same league as TQQQ — halving and halving again stays in the script. One often-missed detail: USD tracks the Dow Jones U.S. Semiconductors Index, not the ICE (ex-PHLX SOX) index behind SOXL — it's far more concentrated in the top names, so a handful of stocks drive most of the ride. The simulation here approximates with SOXX's 10-year data: right direction, different details.
Good fit: long-term semiconductor bulls who want more than 1× exposure and accept that 3× doesn't survive this volatility level — commonly a small USD slice next to a large 1× semiconductor or broad-market position.
Watch out: semiconductors are a cyclical industry — at 2×, a down-cycle still means a −70%-class drawdown (2022 was that league). The prefilled 34.1% CAGR is an AI-bull decade, especially optimistic for a cyclical.
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.
