Option Moneyness and How Traders Talk About It

Moneyness sorts options into in the money, at the money and out of the money, and delta is how traders actually quote it on the desk.

Moneyness describes where an option's strike sits relative to the current price of the underlying stock, split into three buckets: in the money, at the money and out of the money, and traders lean on this vocabulary constantly because it says more about an option's behavior than its raw price does. A call is in the money when the strike is below the stock price, a put is in the money when the strike is above it, and the closer a strike sits to the current price, the more the option's value depends on what happens next rather than on what has already happened.

With a stock at $102, a call struck at $95 is in the money by $7, since exercising it now would be worth $102 minus $95. A call struck at $105 is out of the money, since exercising it now would produce a negative number and no rational holder would do that. A call struck at $100, close to the current price, is described as near the money or at the money in desk conversation even though it is technically $2 in the money, because the label is about proximity to the current price rather than about the exact sign of the intrinsic value.

Puts run in the opposite direction. With the same $102 stock, a put struck at $95 is out of the money, while a put struck at $105 is in the money by $3. The $100 strike put sits near the money in the same way the $100 strike call does, and the two options together, one call and one put at the same near the money strike, form the pair most commonly used to build a straddle, covered in full in the straddles and strangles piece.

Using the $100 strike on the $102 stock from above, assume the call trades at $5.20 and the put trades at $2.79, consistent with the discounted put call parity relationship covered in the parity piece. The call's breakeven at expiry is the strike plus the premium, $105.20, and the put's breakeven is the strike minus the premium, $97.21.

If the stock finishes at $110, the call is worth $10 and the buyer nets $4.80 after the $5.20 premium, while the put expires worthless and its buyer loses the full $2.79 premium. If the stock instead finishes at $95, the call expires worthless for a $5.20 loss, while the put is worth $5 and its buyer nets $2.21 after the premium paid. The near the money strike is where both outcomes stay live until close to expiry, which is exactly why it carries the most premium relative to how far it sits from the current price.
