Meaning
Financial strategies that combine different investment instruments to recreate the risk and return profile of a standard call or put option. A trader creates synthetic options by holding a position in the underlying asset while simultaneously taking an offsetting position in a different derivative. This method allows for the replication of option payoffs when actual options are unavailable or illiquid.
Payoff Mimicry
Combinations of long stocks and short calls result in a profile similar to a short put. When market participants use synthetic options, they can tailor their exposure to specific price movements without being limited by the offerings of a formal exchange. This flexibility is useful for hedging large industrial positions or private equity stakes where standardized contracts do not exist.
The replication depends on the precise mathematical relationship between the price of the stock and the cost of the borrowing.
Funding Requirement
Capital allocation for these structures involves the initial purchase of the underlying security or the posting of margin for a futures contract. Because synthetic options involve multiple legs, the transaction costs may exceed those of a single vanilla option.
Risk Profile
Counterparty risk is a primary concern in over the counter environments where these structures are often traded. These synthetic options rely on the solvency of the bank providing the derivative leg.
