Options Contracts: Rights, Expiry, Settlement, and Buyer–Seller Risk
Summary
The document explains call and put options through their underlying asset, expiry, strike, type, and premium. It distinguishes European-style contracts, which can be exercised only at expiry, from American-style contracts. It also describes cash settlement and automatic expiry exercise on Deribit, using a Bitcoin call example to show how intrinsic value may be paid. Holders can also sell their options before expiry, even when the contract cannot yet be exercised.
The discussion compares buying and writing options. Buyers pay a premium, limiting their loss to that cost while retaining substantial profit potential; sellers collect the premium but can face much larger losses. The text lists time decay, expiry, and implied volatility expectations among considerations for each side. It also gives an example of the platform’s contract naming convention. These are introductory explanations rather than a pricing model or trading system: payoff descriptions are general, and the document does not quantify probabilities, margin, or how market conditions affect option value.
Key ideas
- A call gives its buyer the right to buy the underlying at the strike, while a put gives the right to sell it.
- An option’s key specifications include its underlying, expiry, strike, type, and premium.
- The document describes Deribit options as European-style and cash-settled, with automatic exercise at expiry when they have intrinsic value.
- Buying options limits the buyer’s loss to the premium, while writing options can expose the seller to losses beyond the premium received.
- Option holders can sell their contracts before expiry, even though European options cannot be exercised early.
