Payoff Replication

Principle

Payoff replication involves constructing a portfolio of simpler, more liquid financial instruments whose aggregate cash flows and sensitivities precisely mimic the payoff profile of a target, often more complex or illiquid, derivative. This principle is fundamental to financial engineering and risk management, allowing traders to synthesize desired exposures without directly holding the target instrument. It relies on the concept of no-arbitrage, where two portfolios with identical future payoffs must have the same current value.
