When an option’s strike price is identical to the price of the security. Both call and put options will be simultaneously “at the money.” For example, if the ABC stock is trading at 75, then the ABC 75 call option is at the money and so is the ABC 75 put option. An at-the-money option has no intrinsic value, but may have time value (value if the stock goes up during the period of the option). Options trading activity tends to be most active when options are at the money.
