Put option

A put option gives someone the right to sell a share. In this article, we look at how these financial products work and how you can use them in your investment portfolio. 

Options give you the right to buy or sell something (often shares, but they can be used in connection with other financial assets) for an agreed price on or before a certain date. 

In order to have the option to buy or sell something, you have to pay a fee known as a premium to the seller of the option (who is known as the option writer). You might buy a put option if you thought that a share was likely to fall in price and you wanted to profit from that happening.

Another way to use put options is to hedge your portfolio against a drop in the market. For example, fund managers often buy put options on a stock market index to protect their portfolio so that if the stock market falls, the profits on the option will offset the losses on the shares in the portfolio. 

How put options work

Put options give the holder the right to sell an underlying asset, such as a stock or commodity, at a predetermined price, known as the strike price, at a specific time in the future, known as the expiration date. 

If the price of the underlying asset falls below the strike price by the expiration date, the option holder can exercise the option and sell the asset at the higher strike price, thereby locking in a profit. If the price of the underlying asset is above the strike price at expiration, the option will expire worthless, and the holder will lose the premium paid for the option.

One of the significant advantages of put options is their flexibility. They can be used to protect against potential losses in a stock portfolio, as well as to speculate on the price movement of an underlying asset. 

For example, if an investor holds a significant position in a stock that they believe is overvalued, they could purchase a put option on that stock to protect against a potential price drop.

Potential risks and rewards

As with any investment strategy, put options come with potential risks and rewards. The primary risk of put options is that they expire worthless if the price of the underlying asset does not fall below the strike price by the expiration date. In this scenario, the holder loses the premium paid for the option.

Additionally, the value of put options can be subject to volatility and market fluctuations, making them a potentially risky investment.

However, when used effectively, put options can be a valuable tool in a diversified investment portfolio. 

Using put options in your investment strategy 

When using put options in your investment strategy, it's important to have a solid understanding of the potential risks and rewards. One of the key factors to consider is the strike price of the option. 

A lower strike price may provide more protection against potential losses, but it will also come with a higher premium cost. 

Conversely, a higher strike price may be less expensive, but it may not provide as much protection in the event of a price drop.

Another factor to consider is the expiration date of the option. Longer-term options may provide more protection against potential losses, but they will also come with a higher premium cost. 

Conversely, shorter-term options may be less expensive, but they may not provide as much protection over an extended period.

It's also important to consider the overall goals of your investment strategy when using put options.

If your primary goal is to protect against potential losses in a portfolio, you may want to focus on purchasing put options on individual stocks or indices. 

If your goal is to generate income through the sale of options, you may want to focus on writing put options and collecting premiums.
