At-the-Money (ATM)

At-the-Money (ATM) means an option's strike price (the price you'd pay to buy or sell the stock) is essentially equal to the stock's current market price. You'll run into this term when trading options—contracts that give you the right to buy or sell a stock at a set price by a certain date. ATM options matter because they're right in the sweet spot: they have the most time value (potential to become profitable) and typically the highest trading volume, making them easier to buy or sell quickly. For example, if TechCorp stock trades at $50, a $50 call option is at-the-money. ATM options are neither deep in-the-money (already profitable) nor far out-of-the-money (unlikely to profit).
