NOK Twin-Call Harvest: Down to 20–30% of Premium Left, and No Reason to Wait

Two actions tonight, less than two hours apart.

At 09:53 ET I bought back the NOK 10/23 12C×5 at $0.10; at 11:47, the 12.5C×10 at $0.05. Two limit orders, two clean fills.

These were not new trades — they were early check-outs on two old “leases”. They were rented out on 9/18 and 10/3 (sell-to-open); today the tenants handed back what was left: +$270.13 in total.

2. Why Today: the Tape Delivered the Price, the Ledger Delivered the Answer

NOK fell to $10.08 today (−2.7%), extending last week’s weakness (well below its 20-day average). For anyone holding short calls, that is good news: the 12 and 12.5 strikes drift further away, and the time value evaporates fast.

  • 12C: $0.44 → $0.10 — 23% of the premium left;
  • 12.5C: $0.163 → $0.05 — 31% left.

On the books, 70–80% of the profit is locked in. What remains is the temptation to “wait 11 more days to collect the last 20–30%”.

But those 11 days are not empty: 10/22 is NOK earnings, and 10/23 is expiry. Earnings is a binary event — if it lifts the stock, these two short calls turn from rent collectors into problems to manage; even if it doesn’t, tying up two short legs through earnings week for ~$100 combined buys no safety.

My exit plan was written for 10/15–21 (the pre-earnings window). Today, the conditions arrived early — once the residual value crosses the harvest line, there is no reason to wait. Three days early, the books are settled.

3. Execution: Two Limit Orders, Two Clean Fills

  • 09:53:55 — buy back 12C×5, limit $0.10 — filled;
  • 11:47:39 — buy back 12.5C×10, limit $0.05 — filled.

(System trail, checked while writing: the position-change detector automatically logged both legs’ disappearance right after the fills — every close is now fingerprinted by the system.)

After the buy-backs, NOK’s short legs: only the 11/20 13C×5 remains as the covered call; both 10/23 legs are cleared.

4. Hunter’s Review: Trading “Not Yet Happened” for “Already Banked”

Done right:

  1. Residual-value discipline, again: the same algorithm as September’s NOK harvests — with 70%+ of the profit locked and only 20–30% of premium left, collect; don’t chase the last coin.
  2. Pre-earnings exit, executed early: a window is a range, not a deadline; when the condition arrives first, use it. A binary event avoided at zero cost.
  3. Clean execution: limit orders, two fills, books agreeing to the cent.

Worth noting:

  • If NOK keeps falling before expiry, an even better price was possible — early harvesting is never the optimum; it is the “exchange uncertainty for certainty” solution. Selling options is a game of probability, not of winning every hand.
  • With both short legs cleared, the margin reading will move accordingly — figures to be reconciled at close, and reviewed in the next weekly journal.

Waiting 11 days and an earnings event for the last 20–30% of premium — that math needs no hesitation. The selloff offers the cheap price; discipline offers the reason to bank it: what is left on the table matters more than what happened at the table.
