In-the-Money (ITM)
In-the-money (ITM) is a description of an option's strike price compared to where the underlying stock is currently trading. An option is a contract that gives its buyer the right to buy or sell a stock at a set price, called the strike price, by a certain date. Whether that right currently has intrinsic value determines if the option is "in the money."
For a call option, which gives the right to buy the stock, the option is in the money when the strike price is below the current market price of the stock. That means the holder could, in theory, buy the stock for less than it's currently worth. For a put option, which gives the right to sell the stock, the option is in the money when the strike price is above the current market price, meaning the holder could sell the stock for more than it's currently worth.
The opposite situations are called out-of-the-money, where exercising the option would not make economic sense on its own, and at-the-money, where the strike and the market price are essentially equal. These labels describe the option's position relative to price at this moment; they say nothing about whether the trade as a whole is profitable, since the price originally paid for the option (the premium) also has to be factored in.
The nuance that trips people up is that "in the money" does not mean "profitable." An option can be in the money and still be a loss if the premium paid was larger than the intrinsic value now embedded in the option. It also matters as expiration approaches: an ITM option retains real value and behaves very differently near expiry than an out-of-the-money one, which typically expires worthless.
This term depends on a rule or threshold that changes over time, so no specific figure is quoted here. The definition itself (ITM based on strike vs. market price) is a stable options concept and doesn't hinge on a changeable numeric threshold. However, the original entry's claims about ITM options being 'generally' exercised, assigned, or auto-exercised at expiration touch on brokerage and clearing house mechanics (e.g., OCC exercise-by-exception rules and specific in-the-money thresholds that trigger automatic exercise) that can vary by broker and have changed over time. A human should verify current automatic exercise thresholds and broker-specific assignment practices against OCC and the relevant broker's current disclosures before publishing any specific figures.
Day traders watch ITM status because it drives how an option's price will move relative to the stock (its delta), and because ITM options carry a real risk of automatic exercise or assignment at expiration, which can turn an options position into an unwanted stock position overnight.
A trader holds a call option on a stock with a strike price of $50. The stock is currently trading at $54. Because the strike ($50) is below the market price ($54), the call is in the money by $4. If the trader had paid a $5 premium for the option, the position would still be at a $1 loss overall even though the option itself is in the money.
