AT THE MONEY (ATM)
Back to GlossaryDefinition
Options whose strike price is equal (or very close) to the current price of the underlying asset.
Summary
At the Money (ATM) options are those where the strike price matches (or is very close to) the current market price of the underlying stock or asset. Think of it as the 'break-even point' - if you owned an ATM call option, you'd need the stock price to move above the strike price to make a profit (after accounting for the premium paid). ATM options are significant because they have the highest time value and are most sensitive to changes in the underlying asset's price.
Usage Context
Understanding ATM is crucial when learning about option pricing, the Greeks (especially delta and gamma), option strategies, and making trading decisions based on your market outlook and risk tolerance.
Common Confusions
- Thinking ATM options have intrinsic value (they don't - their value is purely time value)
- Confusing ATM with ITM when the prices are very close
- Not understanding why ATM options are more expensive than OTM despite having no intrinsic value
- Believing that ATM means the option will definitely be profitable
