The price of a European call option on a stock with a strike price of $50 is $6. The stock price is $51, the continuously compounded risk-free rate (all maturities) is 6% and the time to maturity is one year. A dividend of $1 is expected in six months. What is the price of a one-year European put option on the stock with a strike price of $50?

Respuesta :

Answer:

$3.06

Explanation:

The put call parity shows the relationship between the price of European put options and European call options of the same strike price and expiry date.

Given that:

Strike price (K) = $50

Price (C) = $6

rate (r) = 6% = 0.06

Stock price (SO) = $51

Time (T) = 1 year

Dividend (D) = $1

The period of dividend (t) = 6 months = 0.5 years

The put call parity (P) is given by the equation:

[tex]P+SO=C+Ke^{-rT}\\P=C+Ke^{-rT}-SO[/tex]

The dividend present value = [tex]De^{-rt}=1e^{-0.06*0.5}=\$0.97[/tex]

[tex]P=C+Ke^{-rT}-SO\\P=6+50e^{-0.06*1}-(51-0.97)\\P=6+47.088-50.03\\P=\$3.06[/tex]
