Those who know me are aware that I meander through various online communities within web3 through the application known as Discord. Some of you are familiar with Discord, for others that are not it’s a very robust chat software that allows users to connect and share information in very vibrant formats. It is a great platform for gamers, developers, artists, project managers, and ultimately anyone who wishes to engage and cultivate a community.
What does this have to do with options?
Nothing exactly, but that preamble is why I am writing this article as I started a thread within a Discord community for traders, but it is gated behind a pay wall so I wanted to share that information with all of you here, for free. If you are already familiar with options this 101 article may not be for you, but if you have any knowledge gaps or just want to make sure you have sound fundamentals I’d encourage you to keep reading — you just may learn something new as what I consider 101 perhaps is 201 or 301 to you.

OK, let’s hop right into it from here and lay the groundwork starting with basic terminology and some example of how options work:
Option: A financial derivative contract that gives the buyer the right, but not the obligation, to buy or sell an underlying asset at a predetermined price (strike price) within a specified period of time (expiry).
Call Option: Gives the buyer the right to buy the underlying asset at the strike price.
Put Option: Gives the buyer the right to sell the underlying asset at the strike price.
Strike Price: The predetermined price at which the underlying asset can be bought or sold.
Expiration Date: The date when the option contract expires and may no longer be exercised.
Premium: The price paid to purchase an option contract.
Buying Options
When you buy an option, you are paying a premium to gain the right to buy or sell the underlying asset at a fixed price (strike price) until the expiration date (expiry). There are two types of options you can buy: call options and put options.
Example of Call Buying
You believe the price of Company XYZ's stock, currently trading at $50, will go up in the next month. You buy a call option with a strike price of $55 and an expiration date one month from now. By purchasing this call option, you have the right to buy Company XYZ's stock at $55. If the stock price exceeds $55, you can exercise your option and buy the stock at the strike price, making a profit. If it does not your contract will expire worthless and the sell will keep the premium.
Typically the trading platform you use will calculate the premium into your breakeven price. If you paid $1 for the contract, then you will need the underlying to rise above $56 to make a profit: $55 Strike + $1 Premium = $56 Breakeven.
Example of Put Buying
If you think the price of Company XYZ's stock will go down, you can buy a put option. The stock is currently trading at $50, and you purchase a put option with a strike price of $45 and an expiration date one month from now. This put option gives you the right to sell Company XYZ's stock at $45. If the stock price falls below $45, you can exercise your option and sell the stock at the strike price, making a profit.
Again, if we assume the buyer of this put paid a $1 premium, the breakeven price of this contract would be $44. Since this is a put option, we subtract the premium from the strike in this example to get our breakeven: $45 Strike - $1 Premium = $44 Breakeven.
Selling (Writing) Options
When you sell an option, you are taking on an obligation. As the seller (also known as the writer) of the option, you receive the premium paid by the buyer, but you may have to fulfill the terms of the option contract if the buyer decides to exercise it.
Example of Writing a Call
You sell (write) a call option with a strike price of $60 on Company XYZ's stock for a premium of $5. If the stock price remains below $65 (strike + premium) until the expiration date it will expire worthless and you will keep the premium, which is paid up front. However, as the writer of a call option your max risk is limitless as there is no limit to how high XYZ stock price may climb. If the buyer exercises the option at $70, your loss will $5. We take the $70 exercise price, subtract the $60 strike price, and then add the $5 we collected in premium for a loss of $5.
Example of Writing a Put
You sell (write) a put option with a strike price of $60 on Company XYZ's stock for a premium of $5. If the stock price remains above $55 (strike - premium) until the expiration date it will expire worthless and you will keep the premium, which is paid up front. However, as the writer of a put option your max risk is the difference between $0 and the strike, less the premium collected. If XYZ goes to zero your loss is $55. We take the $60 strike price, subtract the exercise price — which in this case is zero — and then we subtract the $5 we collected in premium for a loss of $55.
Buying and selling options contracts can be effective ways to magnify the profits for a smaller invested dollar amount. This is commonly referred to as leverage. When you buy an option they are sold in lots of 100. Let me explain what that means a little deeper and how this works in practice with a real life example using the underlying asset: GS, which is the ticker for my alma mater Goldman Sachs.
First, let us look at how it may appear using Fidelity’s options trading platform as that is the custodian where I personally trade. As of the market close on Wednesday, June 7th, 2023 the underlying asset “GS” is valued at $335.75 per share to provide context for the numbers below.
What is shown here is that we are buying 1 call option with an expiration date of July 21, 2023 at the $350 strike price. The current premium I must pay for this contract is the ask price, which is what the seller (writer) is asking. You may also notice there is a bid price, which is referred to as the spread or my cost if I were to immediately buy 1 contract and then sell it back to the market maker I would lose the difference or the spread between the bid and the ask price of $0.20 per contract.
Since options contracts are sold in lots of 100, if I buy 1 contract there are actually 100 shares of the underlying asset packaged into this contract so my cost for buying 1 contract is not $5.35, but $5.35 x 100, or $535.00, plus the minimal fees charged by Fidelity to facilitate the deal, which is only $0.65 in this case so my all-in purchase price, or cost basis, would be $535.65. If I were to turn around and sell this contract immediately I would realize a loss of $20.65, since the bid is $5.15 x 100 = $515.00.
Typically fees are only charged when you buy a contract, not when you sell one, but that will vary by the platform you use and may also vary depending on the value of the underlying contract as well. Most platforms are very low cost these days, but more importantly beyond the basic fees you will also want to evaluate how much volume is traded on the respective platform as that can impact how tight, or wide, the bid-ask spread may be, which can be a much more significant cost than the fees for buying and selling the options themselves. Personally, I feel that Fidelity has one of the best cost structures when taking volume traded and the tight bid-ask spreads into consideration.
Now that you have a deeper understanding of some of the basic terminology let us discuss what you will encounter when viewing and selecting options that you may want to buy, which is referred to as Buy to Open if you are buying the option or as Sell to Open if you are selling (writing) the option. Conversely when you want to close your position before expiration you would Buy to Close or Sell to Close based on whether you were buying or selling (writing) the options contract.
Quick aside, if you wish to write options, especially naked options you will need to gain certain levels of privilege with the custodian you use and they will have a variety of questions to understand your level of experience with trading options and may carry different capital requirements. A naked option refers to selling (writing) a call or a put where you do not own the underlying. This is considered incredibly risky as your max loss is potentially unlimited as you do not own the underlying asset to hedge your option writing.
If you own GS and you write a call option, the risk to you is merely that your underlying position in GS gets “called away” and you must deliver the share(s) of GS to the buying of your option contract upon expiration. This risk is offset by the premium you collect for the given option. If you do not own GS, then your risk parameters are unlimited in the case of writing naked calls as the price of GS has no upside limitation. Writing naked puts has a defined risk parameter, but is still considered extremely risky as your max loss is the difference between the strike price and the premium you collected, which in the example above the market maker is collecting $5.35 per contract (again they are sold in lots of 100) against the current price of GS trading at $335.75 for a max loss of $330.40 per contract, which when multiplied by 100 gives a real max loss of $33,330.40 if they did not own the underlying shares. Market makers frequently hedge their book by buying and selling the underlying assets themselves to protect their options positions based on if they are in-the-money or out-of-the-money.
This takes us to our next graphic below, which is a view of 10 different strike prices for call options specifically, 5 of which are in-the-money as their strike price is below the current price of GS and 5 of which are out-of-the-money as their strike price is above the current price of GS. This would be inverted we were looking at puts and the in the money puts would be those above the current strike and vice versa.
I won’t describe every aspect of this chart since we are sticking with the 101 level information for right now, but the pieces that anyone with a fundamental understanding of the basics of options should be able to discern are the costs associated with each strike price as shown by the bid-ask prices.
One thing to take note of from a very high level is that the relative probability being assigned to these 10 strike prices can be determined by simply looking at the cost of the option. The 315 call option sells for $27.20 per contract, which is much higher than the 360 call option selling for only $2.62 per contract.
What the market is telling us here is that there is a high degree of confidence that these July 21 GS 315 calls are likely to expire in-the-money — sometimes shown in this less appealing format: GS230721C315. Conversely there is a much lower probability that the July 21 GS 360 calls expire in-the-money.
In our Options 201 class I’ll dive into some of the other aspects here, what they mean, and how to use them wisely. Good luck out there and remember not to dive into options trading without fully understanding what you are doing since options are ways to leverage your money to accentuate the gains they also will deepen the downside and are a fast way to go broke if you do not know what you are doing.
