How QQQ compares

Across the 37 published tickers, the 21-Day Rule finished ahead of holding to expiry on 18 and behind on 19. The QQQ total-return delta of -2.8 pp ranks 20th of 37 (1st is where managing early helped most); the median delta is -1.4 pp.

Without the rule, the standard arm returned 18.1% against 43.5% for buy-and-hold, so the plain wheel trailed holding the shares by 25.5 percentage points in this simulation.

Among its index and broad sector ETF peers DIA, IWM and SPY, the rule finished ahead of holding to expiry on 1 of 3; QQQ itself came in at -2.8 pp.

The separate 10 DTE / 2% OTM wheel snapshot for QQQ shows a put assignment rate of 16.7% and wheel P&L of $10,859 against $21,533 for buy-and-hold. That is a different recipe from the 35 DTE study on this page, so the two results are not additive.

Problem

A single ticker result is context, not a verdict

One ticker and one window prove nothing general; the rule arm sometimes cannot exit at 21 DTE

Solution

What this paired simulation produced

Window and freshness

Period 2024-10-18 to 2026-10-16, refreshed 2026-10-18.

Limitations

Premiums may include model fills (BSM/IV) when market quotes were missing.
  • Simulated results of one fixed recipe over one historical window; not collected income and not a prediction.
  • The rule arm could not exit at 21 DTE on 0 short options and held those to expiry.
  • Modelled pricing: real option bars priced 53% (standard) and 50% (21-Day) of entry fills and 52% of 21 DTE buy-backs; the rest used implied or realized volatility where market quotes were missing.

Frequently Asked Questions

Everything you need to know about getting started

Did the 21-Day Rule help on QQQ?

On this simulation the 21-Day Rule finished -2.8 pp behind holding to expiry — managing early hurt here.

What recipe was simulated?

Same wheel, but the 21-Day arm buys each short option back at 21 DTE; an in-the-money put then takes the shares at that day's close and an in-the-money call delivers them.
