Understanding Put-Call Parity

The video tutorial explains how to achieve the benefits of stock ownership while mitigating risks using put options. It introduces the concept of payoff diagrams and explores how call options can be used to achieve similar outcomes. By combining call options with bonds, one can replicate the payoff of owning a stock and a put option. This leads to the concept of put-call parity, which shows the relationship between different securities and highlights potential arbitrage opportunities.
