Put options are a type of financial derivative that investors use to speculate on or hedge against a decline in the price of an underlying asset, such as stocks, currencies, commodities, and indexes. A put option gives the holder the right, but not the obligation, to sell a specified amount of the underlying asset at a predetermined price (strike price) within a specific time frame. Put options increase in value as the underlying asset's price decreases and lose value as the underlying asset's price increases. They are typically used for hedging or speculative purposes and can be bought or sold, with each strategy carrying its own risks and rewards.

What You'll Learn
Put options as a hedging strategy
Put options are a valuable tool for investors looking to hedge their portfolios against potential losses. By buying a put option, investors can protect themselves from downside risk, especially during uncertain market conditions. This strategy is known as a "protective put" or a "married put".
A protective put involves buying (or owning) stock and purchasing put options on a share-for-share basis. This strategy limits the investor's risk to the difference between the stock price and the strike price, plus the cost of the put option and any commissions. The protection offered by the put option is valid until the expiration date. If the stock price rises, the investor can benefit from the upside potential, less the cost of the put option.
For example, consider an investor who buys 100 shares of XYZ stock at $100 each and also purchases a put option with a strike price of $100 for $3.25. If the stock price declines, the put option provides protection below the strike price until the expiration date. In this case, the maximum risk for the investor is $3.25 per share plus commissions.
The protective put strategy is particularly useful when an investor has a bullish long-term outlook but a bearish short-term forecast. For instance, if there is an upcoming earnings report that could cause volatility in the stock price, a protective put allows the investor to benefit from a positive report while limiting the downside risk of a negative report.
Another use case for protective puts is when an investor believes a downward-trending stock is about to reverse upward. In this scenario, buying a put option when acquiring shares limits the risk if the predicted change in trend does not occur.
It is important to note that buying a put option to limit risk increases the total cost of owning the stock by the cost of the put option. Additionally, the value of a put option erodes over time due to time decay, as the probability of the stock falling below the strike price decreases. Therefore, the protective put strategy is most effective when combined with a bullish outlook on the underlying stock.
Selling put options can also be a part of a hedging strategy. Put sellers typically expect the underlying stock to increase or remain stable. By selling a put option, investors receive cash upfront in the form of a premium. However, if the stock price falls below the strike price, the put seller is obligated to buy the stock at the higher strike price, which can result in significant losses. Therefore, selling puts should be done prudently, ensuring sufficient cash or margin capacity to cover the cost of buying the stock if needed.

Speculative trading with put options
Speculative trading is the opposite of hedging. While hedging is a risk management strategy, speculation involves investors using options to take on risk and generate profit. Speculators generally focus on shorter-term price movements and are willing to take on more risk to generate profit, whereas investments are generally longer-term commitments to price movement.
When an investor buys a put option, they expect the underlying stock to decline in price. If this happens, they can sell the option and make a profit. If the investor's hunch is wrong and the price doesn't fall, they will lose the premium they paid for the option.
There are several ways to speculate with put options. One is to simply buy a put option. Another is to sell a put option, which is a bullish strategy. The buyer of a put option may also sell, or exercise, the underlying asset at a specified strike price.
When deciding whether to speculate with put options, it's important to consider the potential risks and rewards. Put options can provide leverage, allowing investors to control a larger position in options compared to owning the underlying stock. However, this also comes with the potential for greater risk of loss.

Put options vs call options
Put options and call options are the two types of options contracts. Both types have a buyer and a seller. So, while most financial markets have only two types of participants (buyers and sellers), the options market has four: call buyers, call sellers, put buyers, and put sellers.
Put Options
A put option gives the owner the right, but not the obligation, to sell a specific stock at a specific price, on or before a specific date. The value of a put option increases as the underlying stock value decreases. Put options can be used to try to profit from downturns or to protect a portfolio against them.
Call Options
A call option gives the owner the right, but not the obligation, to buy a specific stock at a specific price, on or before a specific date. Call options are typically considered a bullish strategy because the price of the call option usually rises when the price of the underlying security rises.
Buying Call Options vs. Buying Put Options
Traders usually buy call options on a stock when they are very bullish on that stock and want bigger gains than those from simply owning the stock. Conversely, traders usually buy put options on a stock as a means of betting against that stock.
Writing Call Options vs. Writing Put Options
Option writing is typically part of a more nuanced strategy than a simple positive or negative bet on a stock. Traders usually sell options to collect income in the form of a premium, to protect their investment in a stock against losses, or to try to buy a stock at a bargain price.

Risks and benefits of trading put options
Risks
Trading put options comes with several risks that investors should be aware of. Here are some key risks to consider:
- Time Decay: The value of a put option decreases as its expiration date approaches due to time decay. The probability of the stock falling below the specified strike price decreases over time, reducing the option's value.
- Limited Profit Potential for Sellers: Put option sellers have limited upside potential, as the maximum gain is limited to the premium collected from selling the option.
- Significant Downside for Sellers: Put option sellers face significant downside risk if the underlying stock price falls below the strike price. They are obligated to buy the stock at the strike price, which can result in substantial losses if the stock price declines significantly.
- Expiration and Loss: Put options have an expiration date, and if not traded or exercised by that date, the option becomes worthless. As a result, buyers may lose the entire premium paid for the option if it expires out of the money.
- Complexity and Risk Exposure: Trading put options is more complex than simply buying and selling stocks or index funds. It requires a good understanding of the underlying security, strike price, expiration date, and other factors. Speculative trading with put options also requires investors to be correct about the underlying asset, direction, and timing.
Benefits
Despite the risks, trading put options offers several benefits and opportunities for investors:
- Protection Against Downside Risk: Put options can be used as a hedge to protect an investment portfolio against losses when stock prices fall. It allows investors to limit potential losses.
- Profit from Declining Stock Prices: Put options enable investors to profit from declining stock prices. The value of a put option increases as the underlying stock value decreases, providing an opportunity for gains.
- Limited Risk for Buyers: The maximum loss for buyers of put options is limited to the premium paid for the option. This is in contrast to short-selling stocks, which carry theoretically unlimited risk.
- Higher Profit Potential: Put options can offer higher profit potential than short-selling stocks, especially when the underlying asset's price declines substantially.
- Income Generation: Investors can sell put options to generate income by collecting the premium. This can be a reasonable strategy, especially in a rising market.
- More Attractive Buy Prices: Put options allow investors to achieve better buy prices for their stocks. They can sell puts on stocks they want to own but currently find too expensive.

Selling put options
When you sell a put option, you are essentially playing the role of the insurance company. You collect a premium in exchange for agreeing to buy shares at a specific price if they fall. The buyer of the put option has the right, but not the obligation, to sell you their shares at the strike price on or before the expiration date.
There are two possible outcomes when selling a put option:
- The stock stays above the strike price: The option expires worthless, and you keep the premium as a return on your cash or margin.
- The stock falls below the strike price: You are obligated to buy the shares at the strike price, but your actual cost basis is lower due to the premium you collected.
Overall, selling put options can be a useful strategy for generating income and obtaining downside protection in an overvalued market. It is not the perfect tactic for a strong bull market, but it can be tailored to do reasonably well in that scenario as well by selling in-the-money options.
