Rule Summary (Short-Term CE)
Entry is allowed only if ALL conditions pass:
-
Net annualized return > 15% (net of margin interest)
-
Strike selection: ~Δ 0.70 deep ITM call
Rationale: higher probability of ITM finish → faster resolution → monthly rotation.
-
Valuation: stock must trade below fair value
-
Price location: stock should be near a 52-week low
Ideal: within 5% of the 52-week low; acceptable up to 10% in strong-quality names.
How Net Return is Measured
For short-term CE, the reliable “profit engine” is the option’s time value (profit component) captured at entry,
minus margin interest on locked capital.
| Locked Capital (After Extraction) |
(Cost Basis − Premium) × Shares |
| Intrinsic at Entry |
max(0, Stock Price − Strike) |
| Profit Component (Time Value) |
max(0, Premium − Intrinsic) |
| Interest Cost |
Locked Capital × Margin Rate × (Days/365) |
| Net Profit (Proxy) |
(Profit Component × Shares) − Interest |
| Net Annualized % (Exact Days) |
(Net Profit / Locked Capital) × (365/Days) |
Important: This is intentionally conservative and “rotation-first.”
You’re paid for time via profit component. If a trade can’t clear the net yield gate,
you skip it — capital should not sit idle at breakeven.

Strike Rule
Δ≈0.70
Deep ITM for monthly rotation
Pass condition: if the yield gate + valuation + 52W low filters are satisfied,
execute a deep ITM call near Δ 0.70 and rotate monthly.
Yield gate is evaluated using the With Margin result by default (more conservative).
