Expected Price An expected price is a similar tool whereby a pricing model generates an estimated value of the underlying instrument where an option order may be filled. For example, bidding on XYZ call options a few cents beneath theoretical value will likely require the price in the underlying stock to decline to a certain level, referred to as the expected price.
