Exercise turns an option into a share trade, or into a cash payment when the option is cash-settled, as index options are. Expiration is the last moment to exercise, and American-style options can be assigned at any time before it. The articles start from the edges. A short put is assigned early. A Friday holiday moves expiration to Thursday. A long put leaves you short shares. An option near the strike is exercised by exception.
They follow an exercise notice to a short position and show why an exercise can settle the next day under T+1. They compare cash settlement, index options and a financially settled micro E-mini call that leaves no futures position. They also cover an option on a delisted stock and the dividend that raises early-assignment risk on a covered call.
Several check the cash side. Synthetic long stock can carry a $10,000 purchase obligation, and a $1 million net worth can still fall short of funding a $10,000 put assignment. Check your broker’s own exercise and assignment procedures before relying on any timing described here.
