An option that finishes in the money does not always leave its holder with the same asset. Some contracts pay a calculated cash amount, while others require delivery of shares or futures positions. The distinction can transform an apparently straightforward expiration profit into a new position, a funding requirement, or a settlement discrepancy.

For options trading, the settlement method deserves attention well before the final session. The five risks below arise because an option’s quoted value and its contractual obligations follow different paths at expiration.

Physical Delivery Can Create Exposure After the Option Disappears

An exercised equity call typically results in the purchase of shares at the strike, while an assigned short call can require delivery of shares. The option may vanish from the account even as a substantial stock holding or short position appears. An unexpected overnight move then affects that new exposure rather than the expired premium.

Near expiration, inspect the deliverable quantity, automatic exercise threshold, and account treatment of positions created through exercise. A chart showing the option’s final intrinsic value does not reveal whether sufficient capital or stock inventory will be available afterward.

Cash Settlement Can Depend on a Price That Is Not the Closing Quote

Some cash-settled index options use a special opening quotation or another exchange-defined settlement calculation rather than the last displayed index level. A trader who values the contract from the previous session’s close can therefore estimate the wrong payout, especially when constituent shares open at different times or prices.

The absence of physical delivery does not remove pricing uncertainty. Confirm the settlement methodology, valuation date, and publication time. An option can stop trading before the number determining its final cash value becomes available.

Automatic Exercise Can Trigger an Unexpected Funding Requirement

Imagine a hypothetical physically settled call on a listed industrial company with a $70 strike and a 100-share multiplier. The share closes at $70.08 on expiration day, placing the call eight cents in the money. Under an assumed automatic-exercise rule, one long contract converts into the purchase of 100 shares for $7,000, despite having only $8 of intrinsic value at the closing price.

If the account holds $1,200 in free cash, it faces a $5,800 funding gap before considering other collateral or broker arrangements. The broker may restrict exercise, liquidate the resulting shares, or require additional funds under its terms. A small positive expiration value can thus generate a much larger cash obligation. Verify exercise-by-exception rules and available buying power, not just the projected option payoff.

Exercise Cutoffs Can Leave a Hedge Unbalanced

A physically settled option may permit contrary exercise instructions or exercise decisions after regular trading ends, subject to applicable deadlines. Meanwhile, a related CFD hedge can remain open under separate dealing hours and contract rules. If the option is exercised unexpectedly, the intended offset may become excessive; if exercise is declined, the hedge may remain without the position it was meant to protect.

In options trading strategies spanning listed derivatives and CFDs, compare the exchange’s exercise cutoff with the broker’s CFD trading schedule. Account for what happens if one leg changes status while the other cannot be adjusted.

Delivery Rules Can Alter Costs Beyond the Quoted Premium

Physical settlement may bring stock financing, borrow charges, transaction fees, or corporate-action exposure after exercise. Cash settlement instead creates a payment receivable or payable, with its own currency conversion and posting timetable. Neither method is universally cheaper, because the relevant costs arise at different stages.

Before opening a CFD position intended to hedge an expiring option, read the option’s settlement specification and broker exercise policy, calculate any resulting share or futures quantity, and check whether the CFD can be adjusted during the settlement window. That comparison reveals the exposure that may survive after the option itself has expired.
