What Is Option Moneyness?
Moneyness describes the relationship between an option's strike price and the current price of the underlying asset. It tells you whether exercising the option right now would result in a cash inflow (in-the-money), a break-even situation (at-the-money), or a cash outflow (out-of-the-money). Moneyness is one of the most fundamental concepts in options trading and directly affects an option's premium, Delta, Gamma, and Theta characteristics.
Options are classified into three moneyness categories: In-the-Money (ITM), At-the-Money (ATM), and Out-of-the-Money (OTM). Each category has distinct risk-reward characteristics that make it suitable for different trading strategies. Understanding moneyness helps traders select the optimal strike price for their market outlook and risk tolerance.
Moneyness Definitions
| Moneyness | Call Condition | Put Condition | Intrinsic Value | Delta Range |
|---|---|---|---|---|
| Deep In-the-Money | Stock >> Strike | Stock << Strike | Large positive | 0.80 to 1.00 / -0.80 to -1.00 |
| In-the-Money (ITM) | Stock > Strike | Stock < Strike | Positive | 0.55 to 0.80 / -0.55 to -0.80 |
| At-the-Money (ATM) | Stock ≈ Strike | Stock ≈ Strike | Zero or near-zero | ~0.50 / ~-0.50 |
| Out-of-the-Money (OTM) | Stock < Strike | Stock > Strike | Zero | 0.20 to 0.45 / -0.20 to -0.45 |
| Deep OTM | Stock << Strike | Stock >> Strike | Zero | 0.00 to 0.20 / 0.00 to -0.20 |
Moneyness Formulas
Moneyness Example
- 1Simple moneyness = $105 / $100 = 1.05 (5% ITM)
- 2The call is IN-THE-MONEY because Stock ($105) > Strike ($100)
- 3Intrinsic value = $105 - $100 = $5.00
- 4Log moneyness = ln(105/100) / (0.30 × sqrt(30/365)) = 0.04879 / 0.08597 = 0.567
- 5Approximate Delta ≈ N(d1) ≈ 0.70 (70% chance of expiring ITM)
- 6This is moderately ITM, not deep ITM
How Moneyness Affects Your Strategy
Choosing Strikes by Moneyness
- Covered calls: Typically sold 2-5% OTM (Delta 0.25-0.35) for income with upside room
- Protective puts: Often bought 5-10% OTM to reduce cost while providing crash protection
- Bull call spreads: Long ATM call + short OTM call for defined-risk bullish exposure
- Iron condors: Short options 1 standard deviation OTM on both sides (Delta ~0.16)
Implied volatility is not constant across strikes. OTM puts typically have higher IV than ATM options (volatility skew). When comparing moneyness across different stocks, use standardized (log) moneyness which normalizes for volatility and time, allowing apples-to-apples comparison.
An option that starts OTM can become ATM or ITM as the stock moves. An ITM option can become OTM if the stock moves unfavorably. Monitor moneyness regularly to reassess your position's risk profile and determine if adjustments are needed.
Key Metrics Every Options Trader Should Monitor
Successful options trading requires tracking multiple interrelated metrics simultaneously. Implied volatility rank (IVR) indicates whether current option premiums are expensive or cheap relative to historical norms — selling options when IVR is above 50 and buying when IVR is below 25 is a core principle of volatility-based trading. Delta tells you your directional exposure: a covered call with -0.30 delta on the short call means your effective stock delta is +0.70 per 100 shares. Theta decay rate determines how quickly time value erodes — critical for managing the profitability window of your short options. Monitoring these metrics together — not in isolation — defines the difference between systematic options trading and guesswork.
Position sizing in options trading is arguably more important than entry timing. Professional options traders risk 2-5% of total portfolio value per trade, using the maximum loss (for defined-risk strategies) or 20-25% of the premium received (for short strategies managed to 50% profit) as the sizing basis. For covered calls specifically, the 'risk' is the opportunity cost of capped upside — but true capital at risk is the full stock position. This means a covered call position on a $10,000 stock position should be sized as 2-5% of a $200,000-$500,000 portfolio, not a $20,000 portfolio. Proper sizing prevents any single trade from materially harming your overall returns.
