Out of the money: OTM options explained

By Ken Chigbo, Founder, KenMacro. Published 2026-05-13.

What is out of the money?

Out of the money, abbreviated OTM, is an options moneyness classification. A call option is OTM when its strike price is higher than the underlying spot price, and a put option is OTM when its strike sits below spot. Because exercising the contract at that moment would yield a loss versus the open market, the option has zero intrinsic value. Its entire premium consists of time value, which reflects the probability the underlying moves through the strike before expiry. As expiry approaches, time value decays towards zero, and an OTM option that never crosses its strike expires worthless.

How traders use out of the money

Retail traders buy OTM options for cheap, asymmetric exposure: low premium outlay, theoretically unlimited upside if the underlying moves sharply through the strike. The trade-off is a low probability of finishing in the money, which is why most purchased OTM options expire worthless. Institutional desks more often sell OTM options to harvest premium, structuring covered calls, cash-secured puts, iron condors, or risk reversals. Hedgers use OTM puts as tail-risk insurance on equity or FX exposure, accepting the premium cost as the price of protection. Across all participants, the position’s sensitivity to implied volatility, captured by vega, dominates short-dated OTM pricing, so traders monitor IV rank and term structure before initiating either side.

Common misconceptions about out of the money options

The first misconception is that OTM options are cheap and therefore good value. Premium reflects probability: a low price signals the market assigns a low chance of the option finishing in the money. The second is that OTM means worthless. An OTM option retains time value until expiry and can become valuable if the underlying moves or implied volatility rises. The third is that selling OTM options is safe income. Short OTM premium carries open-ended risk if the underlying gaps through the strike, which is why margin requirements and tail-risk hedges matter.

Frequently asked

What is the difference between out of the money and in the money?

In the money means exercising the option would produce a positive payoff: spot above strike for a call, spot below strike for a put. Out of the money is the reverse: exercise would produce a loss versus spot, so the option has no intrinsic value. At the money describes the case where strike and spot are roughly equal. Moneyness determines how much of the premium is intrinsic value versus time value.

Do out of the money options always expire worthless?

No. An OTM option expires worthless only if the underlying fails to cross the strike before expiry. If spot moves through the strike, the option becomes in the money and gains intrinsic value. Before expiry, OTM options can also gain value from rising implied volatility or from spot drifting closer to the strike, even without crossing it. Most purchased OTM options do expire worthless, but the outcome is not automatic.

Why would anyone buy an out of the money option?

OTM options offer leveraged, asymmetric exposure. The premium outlay is small relative to the notional, so a sharp move through the strike can produce a multiple-bagger return, while the maximum loss is capped at the premium paid. Traders use them to express directional conviction cheaply, to speculate on event risk such as earnings or central bank decisions, or to construct spreads that finance a closer-to-the-money long position.

How does time decay affect OTM options?

Time decay, measured by theta, erodes the time value component of every option as expiry approaches. Because OTM options consist entirely of time value, they are especially exposed to theta. The decay is non-linear, accelerating in the final weeks before expiry. An OTM option that sits unchanged while time passes loses value every day, which is why long OTM positions need either a directional move or a rise in implied volatility to be profitable.
