The stock of Angle Industries is currently trading at $60 per share. A 90-day call option on the stock is priced at $7.50. The exercise price of this option is $55. If the applicable risk-free rate of interest is 8%, what is the price of a 90-day put option on Angle Industries with an exercise price of $55?
Also, you can intuitively tell that the put price would be below $7.50. The 55 call is $5 in the money trading at $7.50, so the value of the 55 put, which is $5 out of the money, would obviously be lower than the 55 call.
@Alaric This “put call parity” formula is one of the most fundamental formulas around when it comes to options so it is definitely worthwhile, and actually pretty necessary to learn.
