Understanding the Synthetic Long Put
The synthetic long put combines short stock with a long call, creating a position equivalent to owning a put. By put-call parity, short stock plus long call equals long put at the call strike. This converts an unlimited-risk short stock position into a defined-risk bearish trade. Maximum profit is from the entry price down to zero (limited by the stock floor); maximum loss is defined by the call strike (you would close the short and exercise the call if the stock rallies above the call strike, limiting losses).
The synthetic long put is used by traders who are short stock but want to cap their upside risk at a defined level, essentially buying insurance against a short squeeze. It is also used to replicate a long put position in accounts where buying puts directly is not permitted. In practice, most traders prefer to simply buy a long put rather than maintaining a short stock position with a call, due to the simplicity and capital efficiency of the direct approach..
