How is 00670L different from TQQQ?

Leverage (2× vs 3×), market (Taiwan exchange in TWD vs US exchange in USD), cost structure and trading hours. 00670L needs no overseas account; TQQQ swings harder and trades with more liquidity. To compare directly, set leverage to 3 and costs to 0.84% above — that's TQQQ's parameters.

Is 00670L suitable for dollar-cost averaging?

DCA spreads your entry points, which helps with a high-volatility product, but it doesn't remove daily-reset path dependence or make deep drawdowns shallower. What matters is the position's share of your total assets — and whether you'll keep contributing at −60%.

How much does the exchange rate matter?

It's unhedged: TWD strengthening 5% against the USD costs you roughly 5% of return; weakening adds it back. Long-run FX direction is unpredictable — treat it as extra noise on the return, not a plannable source of gain.

Does 00670L pay dividends?

No. Like 00631L, its exposure comes from futures — the constituents' dividend effect is embedded in the index return rather than paid out. If you want income, look at the plain 1× or dividend-focused products instead.

Can I pair 00670L with 00662 (Fubon Nasdaq-100 1×)?

Yes — and that's exactly what the middle columns simulate: 00662 is the 1× Nasdaq-100, so a 50/50 pairing gives roughly 1.5× effective exposure. It's a dial-your-own-leverage tech position entirely on a Taiwan brokerage account; just set a rebalancing schedule.

00670L (Fubon Nasdaq-100 Daily 2x): Long-Term Hold Simulation

Want leveraged US tech exposure without opening an overseas brokerage account? 00670L trades on the Taiwan exchange in TWD and delivers 2× the daily Nasdaq-100. This page loads its leverage factor and fund costs into the simulator, using QQQ's 10-year return and volatility as the assumptions.

Leveraged ETF Calculator

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

Index

Expected return (CAGR)The 1× index's compound annual growth rate. The leveraged fund is built from this — you don't enter it directly.

VolatilityHow wildly the index's returns swing year to year. This is the engine of volatility decay: the higher it is, the more a 2×/3× fund bleeds in choppy markets.

Leverage & rebalancing

Leverage factorThe leverage of the risky fund, used in both the all-in hold and the blend. Real products offer 2× or 3×.

Rebalancing frequencyHow often each split is traded back to its target weights. Higher frequency tracks the target exposure more tightly and “buys low, sells high” more often, but in practice also means more trading costs and taxes (not modelled here).

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.

Fund costs

Expense ratioThe fund's annual fee, charged on the whole position. Leveraged ETFs typically run 0.9–1.0%, far above a plain index fund's ~0.05%.

Financing rateThe annual interest a leveraged fund pays to borrow its extra exposure. Charged on the borrowed (L−1)× portion, so it hits 3× harder than 2× and never touches 1×. Tracks short-term rates.

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

Over 10 years, going 100% into the 2× QQQ — Nasdaq 100 fund reaches a median 1.7M; a 50/50 split with the 1× index reaches 1.1M, and the plain 1× index 655K — every column rebalanced yearly.

The cost of leverage is drawdown: 100/0 typically falls 52.5% peak-to-trough, versus 40.9% for the 50/50 split.

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.

What this ticker works out to

Under the prefilled assumptions, going 100% 00670L for 10 years lands at a median value of about 1.7M (≈32.6% annualised) — with a median max drawdown of −52.5% along the way. A 50/50 blend with the plain 1× index comes to about 1.1M with the drawdown cut to −40.9%; skipping leverage entirely (pure 1× index) gives about 655K at −27.8%.

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.

How to read this result

The Nasdaq-100 pairs high return with high volatility, and 2× amplifies both: the compounding in bull years is remarkable, but so is the decay relative to a lower-vol index at the same leverage. The middle columns are the interesting ones — part 2× fund, part 1× index usually captures most of the excess return at a much shallower drawdown. There's also a layer the simulator doesn't model: 00670L is TWD-denominated, USD-underlying and unhedged, so the exchange rate stacks directly on your return. Treat it as one more layer of invisible volatility.

Good fit: investors with a Taiwan brokerage account who want to accumulate leveraged tech exposure and can stomach deep drawdowns — commonly run as a satellite next to a broad-market core.

Watch out: a 5% TWD appreciation against the USD takes roughly 5% straight off your return (and vice versa), and the simulator doesn't model it. The prefilled 20.7% CAGR comes from tech's strongest decade ever — discount it yourself.
