How AVGO compares

Across the 37 published tickers, the 21-Day Rule finished ahead of holding to expiry on 16 and behind on 21. The AVGO total-return delta of +6.8 pp ranks 9th of 37 (1st is where managing early helped most); the median delta is -0.4 pp.

Without the rule, the standard arm returned 29.3% against 85.9% for buy-and-hold, so the plain wheel trailed holding the shares by 56.6 percentage points in this simulation.

Among its mega-cap tech and semiconductor peers AAPL, MSFT, ORCL and SMH, the rule finished ahead of holding to expiry on 3 of 4; AVGO itself came in at +6.8 pp.

The separate 10 DTE / 2% OTM wheel snapshot for AVGO shows a put assignment rate of 34.5% and wheel P&L of $25,530 against $14,868 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 2024-10-25 to 2026-10-23, refreshed 2026-10-25.

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 47% (standard) and 49% (21-Day) of entry fills and 49% 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 AVGO?

On this simulation the 21-Day Rule finished +6.8 pp ahead of holding to expiry.

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.
