Please also clarify the significance of risk free rate? Why is it used in put call parity.
Synthetic Call Option: If an investor believes that a call option is over-priced, then he/she can sell the call on the market and replicate a synthetic call.
Borrow the present value of the strike price at the risk free rate and purchase the underlying stock and a put.
Synthetic Put Option: Similar to the synthetic call option. A synthetic put can be created by re-arranging the put-call parity relationship, if the trader believes the put is overvalued.
Synthetic Stock: A synthetic stock can also be created by rearranging the put-call parity identity. In this case, the investor will buy the…
