In finance, the strike price (or exercise price) of an option is the fixed price at which the owner of the option can buy (in the case of a call), or sell (in the case of a put), the underlying security or commodity. The strike price may be set by reference to the spot price (market price) of the underlying security or commodity on the day an option is taken out, or it may be fixed at a discount or at a premium. The strike price is a key variable in a derivatives contract between two parties. Where the contract requires delivery of the underlying instrument, the trade will be at the strike price, regardless of the market price of the underlying instrument at that time. For example, an IBM may call a strike price of $50 a share. When the option is exercised, the owner of the option will buy 100 shares of IBM stock for $50 per share. ==Moneyness== Moneyness is the value of a financial contract if the contract settlement is financial. More specifically, it is the difference between the strike price of the option and the current trading price of its underlying security. In options trading, terms such as ''in-the-money'', ''at-the-money'' and ''out-of-the-money'' describe the moneyness of options. * A call option is in-the-money if the strike price is below the market price of the underlying stock. * * A put option is in-the-money if the strike price is above the market price of the underlying stock. * A call or put option is at-the-money if the stock price and the exercise price are the same (or close). * A call option is out-of-the-money if the strike price is above the market price of the underlying stock. * * A put option is out-of-the-money if the strike price is below the market price of the underlying stock. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Strike price」の詳細全文を読む スポンサード リンク
