20. A call option has an exercise price of $30 and a stock price of $34. If the call option is trading for $5.25, what is the intrinsic value of the option?
$4 Intrinsic value = 34 - 30 = 4
Option Price Characteristics: Stock price (S)
- call price + - put price -
Difference between a call and put option
-Difference is the "time value" of the option. - With time the price curve moves closer to the intrinsic value (value if exercised today). • In general, do not want to exercise call early (put: maybe).
Ina binomial option model with free subintervals. The probability that the stock price moves up every possible time is

A put option on a stock with a current price of $33 has an exercise price of $35. the price of corresponding call option is $2.25. According to put-call parity, if the effective annual risk-free rate of interest is 4% and there are three months until expiration. What should be the value of the put?
2.25-33+35/(1+.04)^(3/12) + 0= 3.91 (call price-current price)+(exercise price/(1+rfr)^ (m/12)
A call option on Jupiter Motors stock with an exercise price of $75 and one-year expiration is selling at $3. A put option on Jupiter stock with an exercise price of $75 and one-year expiration is selling at $2.50. If the risk free rate is 8% and Jupiter pays no dividends, what should the stock price be?
2.50=3.00-So+75/(1+.08)+0 So=69.94

All else being equal, is a put option on a high beta stock worth more than one on a low-beta stock? The firms have identical firm-specific risk.
Higher beta a implies higher total stock volatility. The value of the put option increases as the beta increases.
All else being equal, is a call option on a stock with a lot of firm-specific risk worth more than one on a stock with little firm-specific risk? The betas of the stocks are equal.
Holding beta constant, the stock with high firm-specific risk has higher total volatility. Therefore, the option on the stock with a lot of firm-specific risk is worth more.

Should the rate of return of a call option on a long-term Treasury bond be more or less sensitive to changes in interest rates than the rate of return of the underlying bond?
The call option is more sensitive to changes in interest rates. The option elasticity exceeds 1.0. In other words, the option is effectively a levered investment and is more sensitive to interest rate changes.
Should the rate of return on the of a call option on a long term Treasury Bond be more of less sensitive to changes in interest rates than the rate of return of the underlying bond?
The call option is more sensitive to changes in interest rates. The option elasticity exceeds 1.0. The option is effectively a levered investment and is more sensitive to interest rate changes.
All else being equal, will a call option with a high exercise price have a higher or lower hedge that one with a low exercise price?
The call option with a high exercise price has a lower hedge ratio. Both d1 and N(d1) are lower when X is higher. Holding else equal, as the call option is less in the money, the hedge ratio is also lower.
If the stock price falls and the call price rises, then what has happened to the call option's implied volatility?
The call option's implied volatility has increased. If this were not the case, then the call price would have fallen.
Would you expect a $1 increase in a call options exercise price to lead to a decrease in the option's value of more or less than $1?
The call price will decrease by less than $1. The change in the call price would be $1 only if: (i) there were a 100% probability that the call would be exercised; and (ii) the interest rates were zero.
Would you expect a $1 increase in a call option's exercise price to lead to a decrease in the options value of more or less than $1?
The call will decrease by less that $1. The change in call price would only be $1 if there was a (i) 100% probability that the call would be exercise and (ii) the interest rates were zero.

If the time to expiration falls and put price rises, then what has happened to the put options implied volatility?
The put option's implied volatility has increased. If this were not the case then the put price would have fallen.
If the time to expiration falls and the put price rises, then what has happened to the put option's implied volatility?
The put option's implied volatility has increased. If this were not the case, then the put price would have fallen.

Implication of GGM: stock vs dividend growth
The stock price is expected to grow at the same rate as dividends.
All else being equal, is a call option on a stock with a lot of firm-specific risk worth more than one on a stock with little firm-specific risk? The betas of the stocks are equal.
The stock with high firm-specific has higher total volatility. The option the stock with a lot of firm-specific risk is worth more.
The constant growth version of the DDM asserts that if dividends are expected to grow at a constant rate forever, the intrinsic value of the stock is determined by the formula
V0= D1/ (k-g)
Investor preferences when ROE > k
When ROE exceeds k, the firm offers attractive investment opportunities, so the value of the firm is enhanced as those opportunities are more fully exploited by increasing the plowback rate.
Investor preferences when ROE = k
When ROE just equals k, the firm offers "break-even" investment opportunities with a fair rate of return. In this case, investors are indifferent between reinvestment of earnings in the firm or elsewhere at the market capitalization rate, because the rate of return in either case is 12%. Therefore, the stock price is unaffected by the plowback rate.
Investor preferences when ROE < k
When the expected ROE is less than the required return, k, investors prefer that the firm pay out earnings as dividends rather than reinvest earnings in the firm at an inadequate rate of return. That is, for ROE lower than k, the value of the firm falls as plowback increases.
does the value of a put option increase with the volatility of the stock?
Yes, put values also increase as the volatility of the underlying stock increases
