What Is At The Money?

Describing a call or put option in which the exercise price is the same (or very nearly the same) as the current market price of the underlying asset.

At The Money: Option Trading Term

At The Money (ATM) is a term used in options trading to describe a situation where the exercise price of a call or put option is approximately equal to the current market price of the underlying asset. This is a critical concept in understanding the valuation and strategic use of options in financial markets.

Historical Context

Options trading has been an integral part of financial markets for centuries, with records dating back to ancient Greece. However, the modern options market as we know it began to take shape with the establishment of the Chicago Board Options Exchange (CBOE) in 1973. The concept of “at the money” became standardized as traders and financial analysts sought to classify options based on their relationship to the underlying asset’s price.

Types/Categories of Options Based on Moneyness

  • At The Money (ATM): Exercise price is nearly equal to the current market price.
  • In The Money (ITM): Call options have exercise prices below the current market price, while put options have exercise prices above the current market price.
  • Out of The Money (OTM): Call options have exercise prices above the current market price, while put options have exercise prices below the current market price.

Key Events in Options History

  • 1973: Formation of the Chicago Board Options Exchange (CBOE).
  • 1977: Introduction of options on stock indices.
  • 1982: Introduction of options on futures contracts.
  • 2008: Increase in volatility due to the financial crisis highlighted the importance of understanding options pricing and strategies.

Detailed Explanation

At the money options are important because they generally have the highest extrinsic value compared to in the money or out of the money options. Extrinsic value, also known as time value, is the portion of an option’s price that exceeds its intrinsic value.

Mathematical Formulas/Models

Black-Scholes Model

The Black-Scholes model is commonly used for pricing European call and put options and can be simplified for ATM options:

$$ C = SN(d1) - Xe^{-rt}N(d2) $$
$$ P = Xe^{-rt}N(-d2) - SN(-d1) $$

Where:

  • \( C \) = Call option price
  • \( P \) = Put option price
  • \( S \) = Current stock price
  • \( X \) = Strike price
  • \( r \) = Risk-free interest rate
  • \( t \) = Time to expiration
  • \( N \) = Cumulative standard normal distribution
  • \( d1 \) and \( d2 \) = Factors derived from the Black-Scholes model

Importance and Applicability

At the money options play a critical role in strategies like straddles and strangles where traders seek to profit from volatility. They are often used to hedge portfolios and in speculative trading because they provide a good balance between risk and reward.

Examples

  • Example 1: If a stock is currently trading at $100, an option with a strike price of $100 is at the money.
  • Example 2: For a stock trading at $50, an option with a $50 strike price is at the money.

Considerations

  • Volatility: ATM options are highly sensitive to changes in volatility.
  • Time Decay: These options lose extrinsic value as they approach expiration.
  • Liquidity: ATM options generally have higher liquidity due to increased trading volume.
  • Delta: Measures the sensitivity of an option’s price to changes in the price of the underlying asset.
  • Gamma: Measures the rate of change of delta over time.
  • Theta: Measures the rate of time decay of an option.
  • Vega: Measures the sensitivity of an option’s price to volatility.

Comparisons

  • ATM vs ITM: ATM options have higher extrinsic value but lower intrinsic value compared to ITM options.
  • ATM vs OTM: ATM options have a 50% probability of being profitable at expiration, whereas OTM options have lower probability but higher potential payoff.

Interesting Facts

  • ATM options are often used in delta-neutral strategies because they offer a balance between delta hedging and trading costs.
  • The first organized options market dates back to the 17th century in Amsterdam where Dutch East India Company shares were traded.

Inspirational Stories

A famous options trader, known as the “Turtle Trader”, Richard Dennis, utilized ATM options in his trading strategy to balance risk and reward effectively, leading to substantial returns over his career.

Proverbs and Clichés

  • “Don’t put all your eggs in one basket.”
  • “Risk comes from not knowing what you’re doing.”

Expressions, Jargon, and Slang

  • “Gamma Scalping”: A strategy involving frequently adjusting the delta of a position to remain delta-neutral.
  • “Theta Burn”: Refers to the rapid time decay of an option’s value as expiration approaches.
