A synthetic put is an innovative and sophisticated options strategy that uses two components – a short stock position and a long call option on the same stock – to replicate the potential return on a long put option. This strategy can be useful to traders who have a bearish outlook on a stock and are looking to benefit from a decline in its price.

A long put option gives the investor the opportunity to benefit from an expected decline in the stock price. Specifically, if the stock falls in price, the call option will gain value, and the investor can realize the difference in their favour. A synthetic put works in a similar way but with some important caveats. Instead of a long put, the investor sells the stock short and buys a call option on the same stock. In doing so, the two components effectively create a synthetic long put.

The benefit of a synthetic put is that it can potentially provide a return like a long put option, but with less capital at risk. That is because when a trader buys a long put option they are required to pay the full premium at the outset. On the other hand, when a synthetic put is executed, only the premium of the call option needs to be paid, while the stock is sold short and there is no obligation to pay the full premium of the long put right away.

However, the trade-off is that the synthetic put won’t benefit as much from a dramatic decline in the stock price. If a stock falls significantly in price, the intrinsic value of the long put will increase considerably, whereas with a synthetic put the potential benefit is more limited because the intrinsic value of the call option will be capped.

For traders looking to profit from a bearish outlook on a stock but with limited capital at risk, the synthetic put may be an attractive choice. It is an advanced and sophisticated strategy, however, and traders should be sure to understand the potential risks and rewards before entering into such a position.
