The two choices in options trading  from which all types of options trades are built  are call options and put options. Additionally, there are two aspects, or “sides,” to an options trade: that of the buyer and the seller, or writer. Before we dive deeper into the differences between call vs. put options, let’s refresh our understanding of what options are.

Put VS Call – What’s the Difference?

Just getting started in learning how to trade optionscan be overwhelmingly daunting. However, what if we told you it’s not too difficult to trade options once you learn the basics?

When you’re learning how to trade options, you need to build a sense of how to trade them and gain practical experience over time to become a successful options trader. That said, let’s start with the basics so we can better understand the differences between call options and put options.

Understanding Options Basics and Terminology

It is imperative to first understand what options are themselves before we dive into the finer points of call vs. put option. Here is a list of terms you should be familiar with before you start trading options:

  • An options contract is an option to buy or sell an underlying asset, which could be a stock, index, future or commodity. There is an expiry date associated with the contract before it may be exercised, if at all. Furthermore, the option gives the bearer the right to buy or sell the underlying security but it is not necessary to exercise that right. It is a right and not an obligation.
  • An equity option, or stock option contract, is simply a choice about whether you want to buy or sell shares of a stock at a specified price, on or before a specific date. As you will realize, trading options can be less risky than trading the stocks themselves provided this is done correctly.
  • Another term to understand in the context of options trading is the strike price.” This refers to the price at which you agree to buy or sell the underlying assets through the contract.
  • The fee that is incurred in buying the options contract itself is referred to as the premium.

The Maximum Profits and Losses in Options Trading

There’s one crucial factor to take into account when trading options. If you buy an options contract, your maximum loss is limited to the amount of premium paid. However, you can, in theory, earn unlimited profits.

When you sell an option, it means you are selling the option but the profits will be restricted to the premium. When you sell, or write, an options contract, you receive a credit. However, when you write options, your loss can be theoretically unlimited, in a similar way as the profit of a straight call or put options trade is theoretically unlimited.

Now, let’s take a look at the differences between call options and put options.

Call Options vs. Put Options – Premiums

Both call options and put options give you the right to buy the underlying stock at the specified strike price, on or before the expiration date.

When you’re buying one call option or one put option, you pay a premium to receive the right to buy or sell 100 shares of the underlying stock, respectively. However, you’re not obligated to do so. Think of call options and put options as a placeholder to buy or sell at a specified price that you can claim when the stock reaches said price.

That said, the amount of premium you paid is the maximum amount you could lose. However, if your option expires in-the-money, you would automatically be exercised.

In order to receive the right  but not the obligation  to buy or sell the underlying stock at a specified price any time on or before the expiration date, the owner pays the seller, or writer, the options premium.

Let’s see how the mechanism works and how profits are made or losses incurred in call and put options trading.

  • If you buy a call option, and the underlying stock increases significantly, you could have significant profits. On the other hand, the trader of a put option would suffer.
  • If you buy a put option, and the underlying stock falls significantly, you could have, once again, significant, potentially unlimited profits. In this case, the trader of the call option would suffer.

For call options, remember to pay attention to the strike price. The lower this value, the more valuable your option will be. Conversely, in the case of put options, the higher the strike price of the contract, the more valuable the deal will be for you.

Options Payoff Diagrams

Payoff diagrams are a great way to visualize the profits and losses associated with an options trading strategy. The diagram is basically a visual representation of the outcomes. While the results of the strategy can be depicted in the diagrams at any point in time, the graph is usually used to depict results at expiration time.

While the Y-axis, or the vertical axis, represents the profits or losses, the X-axis, or the horizontal axis, represents the price of the underlying asset.

Needless to say, options payoff diagrams are a valuable analysis tool when planning your call and put options strategies. When you’re trading options, you need to know how your profit and loss will look like at expiration.

Here’s a look at the payoff diagram for call options:

Let us take a deeper look into the above options payoff diagram to understand what it is telling us.

You will note the horizontal line passing through the middle of the diagram represents the horizontal axis. The payoff diagram clearly shows that the losses, shown below the horizontal axis, are capped at the premium paid (seen at the bottom left side of the diagram).

On the right side of the diagram, above the horizontal axis, are the profits, which, as you can see, are theoretically unlimited.

The point at which the curve meets the horizontal line is the break-even point at which neither profits nor losses are made.

Here’s a look at an example of a put option payoff diagram at expiration:

Call option payoff diagram

As you will see, a loss here is incurred in the event of the rising prices of the underlying asset. However, the loss is capped. When the price of the underlying asset falls, as you can see on the left side of the graph above, the profits start coming in with an unlimited scope.

Here’s Why Writing Options is Risky

There are basically two sides to an options trade: the buyer (as in the case of trading call options or put options) and the seller, or writer. Now, the writer of an options contract takes the “opposite side” of risk and receives a premium. However, the writer is obligated to deliver shares of the security if they are exercised, or if the options contract expires in the money.

If you write call options, you would receive a premium for taking on the risk. If you sell, or write, a call option, you are obligated to sell shares of the underlying stock. This happens when the call option holder exercises the option, or if the option expires in the money. In this case, the value of the underlying asset would have increased, but you will be forced to sell it at a price as obligated by the contract. You would, therefore, be at a loss. The amount of the loss will depend on how high the price of the underlying asset changes.

If you write a put option, you are obligated to purchase shares of the underlying stock. This is if the put option expires in the money or the holder exercises the option. This time, you will have to purchase the underlying assets from the option holder at a price that is much higher than the market price. You will, once again, be at a loss which is theoretically unlimited.

There are two forms of call writing: naked writing and covered writing. Covered call writing is when a trader uses stocks that they own themselves when writing calls. In the case of naked call writing, you sell call options without first owning them yourself.

Writing Naked Options Is Risky Business

Keep in mind that naked writing of options, or selling without hedging, is hazardous. You should not actually look to write or to sell options naked when you’re first starting out. Moreover, you’re going to need some collateral if you’re looking to write options in order to collect the premium.

It’s also important to have the right mindset and know when to trade options considering the market trends. If you are bullish on an asset, consider buying a call, and if you are bearish, a put option. This will enable you to make profits when the price of the underlying asset rises or falls, respectively.

Final Thoughts

When you’re learning how to trade call and put options, you need to understand the basics first. We saw how an option is basically a contract that functions in the manner of a right without an obligation and must be used before a certain date. It is really important to consider the expiration date, as it has a bearing on your trading strategy. It will also affect the risk and profit dynamics.

We saw how the potential loss is limited to the premium when buying call options but when you write options, it can be very risky indeed. It is advisable to focus primarily on buying options when you’re first starting to learn how to trade options, or possibly by using a spread options trading strategy to help minimize, or spread, the risk of selling the option.

Be sure you’re comfortable with the ins and outs of call and put options trading before you spend hard-earned money on ill-advised options. Develop your trading plan before you buy your first call or put option. Seasoned professionals are only professionals because they put in the time to make a well-thought-out trading plan.
