Decision and objectives

Decision: Identify what exercise creates: shares, futures and cash require different funding and leave different residual risk. Objectives: Distinguish option delivery into shares, futures or cash; Calculate gross exercise funding; Stress assignment mismatch across related products. Prerequisite: C6T4L2.

All numerical offers, rates, prices, account chains, fees and contract parameters below are hypothetical, unless a primary document is expressly identified. They are not current executable offers or evidence that a Turkey-resident investor can access them. The assumed investor is a Turkey-resident individual outside a business, with no assumed US citizenship or tax residence; actual classification must be checked. Results are before actual tax unless a fictional tax schedule is explicitly supplied. No account, deposit or trade is required.

Mechanics

Options on a share, an ETF, an index and a future can have different exercise styles and deliverables even when they refer to similar market exposure. A physical equity or ETF option can exchange securities for strike cash; a cash-settled index option resolves a value difference; a futures option can create a futures position. Do not assume the same last trading time, exercise threshold or automatic processing. The OIC assignment reference discusses US OCC-cleared contracts; verify the actual product and clearing rules rather than transferring its procedures toTurkey or another exchange.

Price and return drivers

For a physical call, holder pays strike× deliverable units and receives stock; writer receives that cash and delivers stock. Physical puts reverse the stock exchange. A futures-option exercise can leave a future with daily settlement and margin that were absent in the fully paid option. American rights can be exercised before expiry and shorts can be partially assigned. A European long wing at a later expiry cannot automatically settle an earlier American short obligation. Economic similarity does not synchronize cash dates.

Worked case

Compare three independently declared synthetic calls, one each, K 100, multiplier 100, premium 6, total charges 20. A European cash index call at final fixing 115 pays 1500, net 880. An American physical ETF call atS 115 requires 10000 strike cash and receives 100 units worth 11500; net economic gain 880 at that mark, but shares remain exposed. A call on a cash-settled future exercised when the future is 115 creates a long future at 100 with 1500 value difference under the specified accounting; the resulting position also needs hypothetical 3000 collateral. Premium affordability 620 does not establish that 3000 margin or 10000 physical funding is available.

Adverse case

At resolved underlying/futures prices 80, 100, 115, the plain call’s net economic outcomes are−620, −620, +880 if rights and settlement are completed as assumed. Before expiry, an American short ETF call can be assigned while a related index hedge remains open. If 100 ETF shares must be bought at 120 and delivered at 100, market purchase 12000 versus strike receipt 10000 creates 2000 loss before the hedge and fees. A futures option holder who exercises and then sees the future fall 115→105 loses 1000 on the new future; the original option loss boundary no longer describes the resulting open future. A pre-expiry sale bid 16 for the original call would instead net 980 without exercise delivery.

Practical use

Read exchange product specifications, OCC or other clearing terms, and the intermediary’s exercise instructions and delivery policy. Confirm corporate-action-adjusted deliverables, ex-dividend dates and existing assignment notices. Actual exercise/assignment deadlines are operational parameters to recheck, not facts to memorize from this exercise.

Before implementation verify the legal entity, jurisdiction, authorized access, actual instrument identifier and full documents. Include bid/ask, commissions, transfer/FX, custody, funding and exit costs; avoid deducting already embedded fund expenses twice. Recheck residency, income year, acquisition dates, withholding, treaty and domestic declaration treatment. Foreign tax concessions or investor protections do not follow automatically from the instrument name or trading currency.

Decision boundaries

Choose a cash-settled or physical route according to the ownership and cash objective. Close before expiry when the investor cannot support the resulting shares or futures and an acceptable bid exists. Decline a spread described as fully protected if its short and long legs cannot meet obligations together. Do not intentionally exercise merely to avoid a trading commission without comparing lost time value, funding and delivery costs.

Practice and references

Exercise: two physical putsK 50, multiplier 100, premium 3 each, total fees 30. Solution: A long holder exercising needs 200 deliverable shares and receives 10000 strike cash. AtS 40, shares are worth 8000; put economic payoff 2000, net 1370. A short assigned holder needs 10000 purchase cash and receives 200 shares. A cash-settled comparison would exchange only the 2000 difference.

Takeaway: Identify what exercise creates: shares, futures and cash require different funding and leave different residual risk. References: product card, formula; glossary: Futures option; Physical ETF option; American assignment. Next: C6T4L4. Topic test.
