Explanation
A Short Put Ladder is a bearish option strategy when trader is bullish on volatility. This strategy is executed for net credit and is the extension of Bull Put spread. The only difference between Short Put Ladder and Bull Put spreadis theadditional lower strike bought.The purpose of buying the additional out-of-the-money (OTM) strike is to get unlimited reward if the underlying securityfalls as per trader’s expectation.
For implementing this strategy required sale of an in the money (ITM) Put Option and buying of 1 at-the-money (ATM)& 1 out-of-the-money (OTM) Put Options.
Risk
Risk associated with this strategy is limited. Loss potential for this strategy is limited and occurs when price of the underlying at expirytrades between strike prices of the put options bought. The short put and the middle put will trade ITM and further OTM put will expire worthless.
Reward
Maximum gain can occur in two scenarios
- If the underlying price rises beyond the short put, at that moment the strategy implementer will get to keep the net premium received.
- Another scenario could be, if the underlying price fall below the long OTM put. In that situation both long put will become ITM, one put option profit will compensate for short put and other will result in straight profits.
