Standard Option Styles and Listed Contracts

Option terms for American, European, Bermuda, vanilla, listed, exchange-traded, LEAPS, and low-exercise-price structures.

Standard Option Styles and Listed Contracts is the financial-instruments landing page for option rights, holders, writers, calls, exercise prices, expiration dates, moneyness, contract styles, listed options, option classes, chains, underlyings, warrants, and real options. It keeps related terms in one branch so readers can move from a broad instrument question to the article that owns the contract evidence.

Use this page when an option contract term changes rights, obligations, exercise timing, moneyness, or underlying exposure. Use the parent Options Contracts and Exercise Features page when you need the broader instrument map. For an individual decision, confirm the contract, term sheet, prospectus, confirmation, exchange specification, or disclosure record before relying on the term.

Use the table below to choose the branch that matches the instrument type, payoff feature, settlement term, or risk exposure being reviewed.

Example in Use

A call option gives the holder a right to buy, but the call writer may have an obligation if the holder exercises.

What to Check

Underlying, call or put type, strike price, expiration date, exercise style, contract size, and settlement method.
Holder right, writer obligation, premium, margin, moneyness, early-exercise terms, and assignment risk.
Listed or OTC venue, option class, option chain, liquidity, corporate action, and underlying reference asset.
Effect on payoff, leverage, hedging, volatility exposure, and risk of loss.

Common Mistakes

Confusing the option holder right with the writer obligation.
Ignoring expiration, exercise style, contract adjustments, and margin before evaluating risk.
Assuming every option is exchange-traded, standardized, liquid, or suitable for every investor.
