Short Put (Naked put/ uncovered put)

The short put, or naked put, is an options trading strategy where an investor sells put options without holding a position in the underlying asset. This strategy is used by traders who expect the underlying asset to remain stable or increase in price, allowing them to profit from the premium received from selling the puts.


The Setup

Imagine you believe that a company called SteadyRise, currently trading at $50 per share, is unlikely to drop significantly in the near future due to strong financials and market position. You decide to sell a naked put option with a strike price of $45 that expires in three months, and you receive a premium of $3 per option.


Who Should Consider It

The short put strategy is suitable for investors with a neutral to bullish outlook on the underlying asset and who are willing to assume the risk of buying the stock at the strike price if the stock falls below it. It is preferred by those looking to generate income through premiums, assuming they are comfortable with the potential obligation to purchase the stock.


Strategy Explained

By selling a put option, you are obligating yourself to buy the underlying asset at the strike price if the option buyer decides to exercise the option. This happens if the asset's price falls below the strike price at or before expiration. If the asset's price stays above the strike price, the option expires worthless, and you keep the premium as your profit.


Breakeven Process

The breakeven point for a short put strategy is calculated by subtracting the premium received from the strike price. In the SteadyRise example, the breakeven would be $45 (strike price) - $3 (premium received) = $42. The stock price needs to stay above $42 by expiration for you to avoid a loss.


Sweet Spot

The sweet spot for this strategy is when the underlying asset's price stays above the strike price, allowing the put option to expire worthless and you to retain the entire premium.


Max Profit Potential

The maximum profit is limited to the premium received for selling the put option. In this example, that would be $3 per share.


Max Loss

The maximum loss occurs if the underlying asset goes to zero, in which case you would be obligated to buy a worthless asset at the strike price. Thus, the potential loss can be substantial, up to the strike price minus the premium received ($45 - $3 = $42 per share).


Risk

This strategy involves significant risk, as you may end up having to buy the underlying asset at a price much higher than the market value if the asset's price falls below the strike price. The risk is similar to that of owning the stock, but with the added potential benefit of the premium income if the put expires worthless.


Time Decay

Time decay works in favor of the short put strategy. As the expiration date approaches, the value of the option generally decreases if the stock price is above the strike price, increasing the likelihood that you will keep the premium.


Implied Volatility

A decrease in implied volatility is beneficial for this strategy after the put is sold because it reduces the likelihood that the option will be in the money by expiration. Conversely, increasing volatility increases the risk that you will have to purchase the stock at the strike price.


Conclusion

The short put option strategy can be an effective way to generate income if you are confident that the underlying asset's price will not fall significantly. However, the potential for substantial losses makes it important to manage risks carefully. This strategy should be employed by experienced investors who have the financial capability to purchase the underlying asset at the strike price if required.
