This page describes a simple, rules-based SPY covered call strategy that operates on a
daily cycle. The goal is to harvest option premium consistently, while using a clear decision process
for what to do when the covered call expires out-of-the-money (OTM) or
in-the-money (ITM).
Core Idea
You hold 100 shares of SPY and sell a daily (or very short-term) covered call
against those shares. At the end of each trading day, you evaluate the option at expiration and follow a
fixed set of rules:
- If the call expires OTM → keep shares and sell a new ATM call the next morning.
- If the call expires ITM but only slightly (intrinsic value < $3) → roll to the next day.
- If the call expires ITM by $3 or more → allow assignment, then buy back SPY next morning and sell a new ATM call.
This structure turns SPY into a daily income engine while keeping the rules mechanical
and easy to follow.
Step 1: Initial Setup
- Buy 100 shares of SPY.
- Sell 1 ATM covered call on SPY that expires the same day (or the nearest available daily expiration).
- Hold the position until the option expires at the end of the session.
From here, your day-to-day logic is completely determined by how that call finishes at expiration.
End-of-Day Decision Rules
At expiration, compare the closing price of SPY to your call strike:
| Condition at Expiration | Action | Comment |
|---|---|---|
| Call expires OTM (SPY close ≤ strike) | Next morning: sell a new ATM covered call | You keep the shares and keep 100% of the premium. |
| Call expires ITM and (SPY close − strike) < $3 | Roll the call to the next day | Take assignment risk off by rolling; treat this as “small ITM, keep the position alive.” |
| Call expires ITM and (SPY close − strike) ≥ $3 | Allow shares to be called away. Next morning, buy 100 shares of SPY again and sell a new ATM call. | Lock in the gain on SPY (≥ $3 ITM) plus premium, then immediately re-establish the covered call. |
Rule Logic in Plain English
1. OTM at Expiration: Premium Harvest Mode
If SPY closes at or below your strike:
- The option expires worthless.
- You keep all the call premium as profit.
- You still own your 100 SPY shares.
- Next morning: sell a fresh ATM covered call again.
This is the ideal scenario: you collected income and kept the stock. The strategy simply repeats.
2. Slightly ITM (< $3 Intrinsic): Rolling Mode
If SPY closes above the strike, but the difference is smaller than $3:
- SPY close – strike < $3 (for example, strike 500, SPY close 501.50).
- Intrinsic value is small; you don’t want to lose the shares cheaply.
- Action: roll the covered call to the next day (same or adjusted strike, new expiration).
Rolling allows you to:
- Maintain your long SPY position.
- Collect additional premium on the new call.
- Smooth out small ITM moves without constantly having shares called away.
3. Deep Enough ITM (≥ $3 Intrinsic): Realize Profit & Reset
If SPY closes at least $3 above your strike:
- SPY close – strike ≥ $3 (for example, strike 500, SPY close 504).
- You’ve captured a meaningful move in SPY plus the original call premium.
- Action: let the shares be called away (assignment is fine).
Then, on the next morning:
- Buy 100 shares of SPY again at the new price.
- Sell a new ATM covered call expiring that same day.
This locks in a larger realized profit when SPY makes a strong move, then immediately restarts the
income engine at the new price level.
Daily Routine Summary
- Morning: own 100 SPY, sell 1 ATM call expiring today.
- Close: check where SPY finishes relative to the strike:
- OTM → do nothing overnight; next morning, sell new ATM call.
- ITM, < $3 intrinsic → roll the call to the next day.
- ITM, ≥ $3 intrinsic → allow assignment; next morning, rebuy SPY and sell new ATM call.
Risk Management Notes
- This is still an equity strategy; you carry SPY price risk.
- The call premium helps cushion small drops but does not fully protect against large selloffs.
- You can reduce risk by:
- Keeping position size appropriate for your account.
- Avoiding selling calls through major events (CPI, FOMC) if desired.
- Optionally turning the call into a call spread to cap risk.
Who This Strategy Is For
- Traders comfortable holding SPY as a core position.
- Covered-call investors who want a daily, rules-based framework.
- People who prefer clear “if–then” rules instead of discretionary decisions.
By following the rolling logic consistently—OTM → new ATM call, small ITM → roll, large ITM →
realize profit and reset—you turn SPY into a disciplined daily income strategy.
