Covered Put Explained

Covred put
A Covered Put has less risk than selling 100 shares of stock. The strategy is completely the opposite of the covered call.  This strategy is used by traders that has a bearish assumption. That means that they use this option strategy for stocks that may drop in price. The way you set this strategy up is by shorting stock and selling its associated put option.

Investors that trade the Covered Put will receive an initial credit from shorting the stock as well as the option premium from selling the associated put option. In this way you are increasing your probability of profit.

A covered put strategy becomes profitable when the associated option expire with the market stock price below the credit received and above the initial short stock price. The underlying can go up a little bit (the credit received), stays the same, or go down and the trade will be profitable.

Setup Covered Put

Sell the short put options out of the money (OTM) with -30 deltas and with 45-50 days to expiration. Make sure that you receive enough credit from the short put. Otherwise the trade is not worth our while. Sometimes it can be hard to find enough premium at -30 deltas. When this is case, move the short put closer at the money (ATM) to collect more premium. If the at the (ATM) strike price still doesn’t offer enough premium, we may look to trade other strategies or wait for IV to increase.


Calculating max profit

Max profit occurs when the options expire with the underlying at or below the short put’s strike price. To calculate the trade’s max profit, take the short stock price minus the short put’s strike price plus the credit received for selling the put.


Close the Trade

The moment you want to close the trade you need to buy the underlying stock back. Your aim  is to buy it back cheaper than the price you have shorted it for. If the stock price is above the put option’s strike price, you can let it expire worthless. However, if the stock price is below the option’s strike price, you will need to buy the option back.

As can be seen from the diagram, the Covered Put produces a profit profile that favors the stock price going down. Shorting the underlying stock means that if the price of the stock goes up, you may have loss. You will experience much more loss when the stock price climbs higher.

But this also means that the more the stock price falls, the more you earn. Selling the associated put option has three effects on this trade.

  • It pushes the breakeven point higher. This gives you a larger margin of error, that is the stock price can climb higher before you start to incur losses.
  • Selling the put option increases your profit. As long as the stock price is above the put option’s strike price, your profit will be greater than if you hadn’t sold the put option.
  • It limits your potential profit from this trade. If the stock price drops below the put option’s strike price, the put option will no longer expire worthless and you will need to buy it back. The gains from shorting the underlying stock will match and cancel out the loss incurred from buying back the put option. This effectively means that your profit is capped once the stock price goes below the put option’s strike price.


Naked Call Writing

An alternative but similar strategy to writing covered puts is to sell naked calls. Naked call writing has the same profit potential as the covered put but is executed using call options instead.


The Covered Put strategy is a very different beast compared to other bearish strategies   or even simple trades such as buying a basic put option. It is a credit position which does not require an initial outlay, and actually comes with a huge initial credit surplus. You will also start seeing profit at a higher break even point. However, this comes with the risk of the stock price going up and causing huge losses.

The Covered Put is a credit position providing initial income. You can earn a capped profit if the stock price falls, but can incur unlimited losses if the stock price rises.
