Suppose you are an options trader and believe that XYZ Corporation's stock, which is currently trading at $50 per share, will decline in value over the next few weeks. You decide to sell a naked call option.
Step 1:  Choose the Option Contract
You select a call option contract with the following details:
Strike Price:  $55
Price Per Option:  $3
Number of Contracts:   2
Step 2:  Determine Your Maximum Profit
The maximum profit for selling a naked call option is the total premium you receive:
Max Point =  Price Per Option x Number of Contracts x 100
Breakeven Point =  $3 x 2 x 100
Breakeven Point =  $600
Step 3:  Calculate Your Breakeven Point
To calculate the breakeven point, add the strike price to the premium received:
Breakeven Point =  Strike Price + Option Premium
Breakeven Point =  $55 + $3
Breakeven Point =  $58 per share
This means that the stock's price must stay below $58 per share for you to make a profit. If the stock's price goes above $58, your losses start to accumulate.
Step 4:  Determine Your Maximum Loss
The maximum loss for selling a naked call option is theoretically unlimited because there's no upper limit to how high the stock's price can rise. Your loss increases as the stock price rises above the strike price.
Step 5:  Monitor the Trade
Keep a close eye on the stock's price movement. If it remains below the strike price of $55, you can potentially keep the entire premium as your profit. If the stock's price rises above the strike price, your losses will increase as the price moves higher.
Step 6:  Decide When to Close the Position
You should have a plan for when to close the naked call option position. If the stock's price starts rising and you begin to incur significant losses, you may want to consider buying back the call option to limit your potential losses. Alternatively, you can wait until expiration if the stock price remains below the strike price.
Step 7:  Closing the Position
Suppose the stock's price indeed declines, and you decide to close the position before expiration. To do this, you would buy back the same call option contract you initially sold. The cost to buy it back will depend on the current market price of the option. If the option price has fallen, you might be able to buy it back at a lower price, resulting in a profit.
Disclaimer
Remember that options trading carries significant risks, especially when using strategies like naked call options. Always have a risk management plan in place and consider consulting a financial advisor or broker for guidance before engaging in options trading.
