:''Further information: Option: Model implementation'' In finance, a price (premium) is paid or received for purchasing or selling options. This price can be split into two components. These are: * Intrinsic value * Time value ==Intrinsic value== The ''intrinsic value'' is the difference between the underlying spot price and the strike price, to the extent that this is in favor of the option holder. For a call option, the option is in-the-money if the underlying spot price is higher than the strike price; then the intrinsic value is the underlying price minus the strike price. For a put option, the option is in-the-money if the ''strike'' price is higher than the underlying spot price; then the intrinsic value is the strike price minus the underlying spot price. Otherwise the intrinsic value is zero. For example, when a DJI call (bullish/long) option is 18,000 and the underlying DJI Index is priced at $18,050 then there is a $50 advantage even if the option were to expire today. This $50 is the intrinsic value of the option. In summary, intrinsic value: : = current stock price – strike price (call option) : = strike price – current stock price (put option) 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「Valuation of options」の詳細全文を読む スポンサード リンク
