Selling (writing) a put option allows an investor to potentially own the underlying security at a future date and at a much more favorable price. In other words, the sale of put options allows market players to gain bullish exposure, with the added benefit of potentially owning the underlying security at a future date and at a price below the current market price.
Call Options vs. Put Options
A quick primer on options may be helpful in understanding how writing (selling) puts can benefit your investment strategy, so let's examine a typical trading scenario as well as potential risks and rewards.
An equity option is a derivative instrument that acquires its value from the underlying security. Buying a call option gives the holder the right to own the security at a predetermined price, known as the option exercise price. Conversely, a put option gives the owner the right to sell the underlying security at the option exercise price. Thus, buying a call option is a bullish bet—the owner makes money when the security goes up—while a put option is a bearish bet - the owner makes money when the security goes down.
Selling a call or put option flips over this directional logic. More importantly, the writer takes on an obligation to the counterparty when selling an option because it carries a commitment to honor the position if the buyer of the option decides to exercise their right to own the security outright.
Here's a summary breakdown of buying vs. selling options.
- Buying a Call: You have the right to buy a security at a predetermined price.
- Selling a Call: You have an obligation to deliver the security at a predetermined price to the option buyer if they exercise the option.
- Buying a Put: You have the right to sell a security at a predetermined price.
- Selling a Put: You have an obligation to buy the security at a predetermined price from the option buyer if they exercise the option.
How To Sell Put Options To Benefit In Any Market
Characteristics of Prudent Put Selling
- Sell puts only if you're comfortable owning the underlying security at the predetermined price, because you're assuming an obligation to buy if the counterparty chooses to exercise the option.
- Only enter trades where the net price paid for the underlying security is attractive. This is the most important consideration in selling puts profitably in any market environment.
- Other benefits of put selling can be exploited once this important pricing rule is satisfied. The ability to generate portfolio income sits at thea top of this list because the seller keeps the entire premium if the sold put expires without exercise by the counterparty.
- Another key benefit is the opportunity to own the underlying security at a price below the current market price.
Put Selling In Practice
Let's look at an example of prudent put selling. Shares in Company A are dazzling investors with increasing profits from its revolutionary products. The stock is currently trading at $270 and the price-to-earnings ratio is at a level that is an extremely reasonable valuation for this company's fast growth track. If you're bullish about their prospects, you can buy 100 shares for $27,000 plus commissions and fees.
As an alternative, you could sell one January $250 put option expiring two years from now for just $30. That means the option will expire on the third Friday of January two years from now and has an exercise price of $250. One option contract covers 100 shares, allowing you to collect $3,000 in options premium over time, less commission.
By selling this option, you're agreeing to buy 100 shares of Company A for $250 no later than January two years from now. Clearly, since Company A shares are trading for $270 today, the put buyer isn't going to ask you to buy the shares for $250. So, you'll collect the premium while you wait.
If the stock drops to $250 in January two years from now, you'll be required to buy the 100 shares at that price, but you'll keep the premium of $30 per share so your net cost will be $220 per share. If shares never fall to $250, the option will expire worthless and you'll keep the entire $3,000 premium.
Summing up, as an alternative to buying 100 shares for $27,000, you can sell the put and lower your net cost to $220 a share (or $22,000 if the price falls to $250 per share). If the option expires worthless, you get to keep the $30 per share premium, which represents a 12 percent return on a $250 buy price.
You can see why it's attractive to sell puts on securities you want to own. If Company A declines, you'll be required to cough up $25,000 to buy the shares at $250 (having kept the $3,000 premium, your net cost will be $22,000). Keep in mind your broker can force you to sell other holdings to buy this position if you don't have available cash in your account.

The Bottom Line
The sale of put options can generate additional portfolio income while potentially gaining exposure to securities you would like to own but at a price below the current market price.
