$2,750

Monday.s close is 124.26, and Tuesday.s close is 122.29. What is in your margin
account after Tuesday’s settle?
.Who receives the money taken out of your margin account?

Options
.The Black-Scholes option pricing model (the model most
commonly used to price and value options) is a function of:
.the spot price of the underlying asset
.the exercise price on the option
.the option.s exercise date
.the price volatility of the underlying asset
.the risk-free rate of interest
.The intrinsic value of an option is the difference between
an option.s exercise price and the underlying asset price .the intrinsic value
of a call option = max{S – X, 0}
.the intrinsic value of a put option = max{X – S, 0}
Option Intrinsic Value and Time Value
•The May call is in the money (positive intrinsic value) and
the call premium is $3.30 * 100 = $330 (contracts are for 100 shares)
•The intrinsic value of the call (S-X) is ($8.79 - $6.00) *
100 = $279
•The time value of the call is $330 - $279 = $51
•The May put is out of the money and the put’s intrinsic
value (X-S) is 0
•The put still has time value, however, equal to $0.45 * 100
= $45

traded on an exchange and as such
would come under the purview of the SEC and CFTC
.Bank regulators will presumably more tightly regulate bank
usage of derivatives
