Day 4: What are Options? Call Options and Put Options

I. Introduction to Options

A. Definition of Options

Options are a type of derivative security, meaning their price is “derived” from the price of an underlying asset. This asset could be a stock, bond, commodity, currency, index, or another financial instrument. An options contract offers the buyer the opportunity, but not the obligation, to buy (in the case of a call option) or sell (in the case of a put option) the underlying asset at a predetermined price (the strike price) on or before a specific date (the expiration date).

B. Comparison between Options and Other Financial Instruments

Options are distinct from other financial instruments due to their unique risk-reward structure. Unlike stocks, where an investor’s potential loss is limited to their initial investment and their potential gain is theoretically unlimited, options can have different risk and reward profiles depending on whether one is the buyer or seller of the option, and whether it’s a call or put option.

Stocks: When you buy a stock, you own a piece of the company and your potential loss is capped at the amount you invested. The potential gain, on the other hand, is unlimited as the company’s stock price could rise indefinitely.
Bonds: When you buy a bond, you are lending money to the issuer (like a government or corporation). In return, the issuer promises to pay you interest at regular intervals and return the principal at maturity. The potential gain is the interest income and potential loss is the principal amount (if the issuer defaults).
Futures: Futures are an obligation. If you buy a futures contract, you are agreeing to buy the underlying asset at a future date. The potential gain or loss can be significant as it’s based on the full value of the underlying asset.
Options: Unlike futures, options are not an obligation. As an options buyer, your potential loss is limited to the premium (the price you paid for the option). However, your potential gain can be substantial if the market moves in the desired direction.

C. Basic Terminology: Strike Price, Expiration Date, Premium

Strike Price: This is the price at which the underlying asset can be bought (for call options) or sold (for put options) as specified in the options contract.
Expiration Date: This is the date at which the options contract becomes void. The holder of an option must exercise their right to buy or sell the underlying asset before or on the expiration date.
Premium: This is the price that the buyer of the option pays to the seller to obtain the rights that the option grants. The premium is determined by various factors including the underlying asset price, strike price, time until expiration, volatility of the underlying asset, and the risk-free interest rate.

The study of options opens a new vista in financial markets, providing investors more strategies and tactics to mitigate risk, speculate, and potentially earn profits. This flexibility and versatility are part of the allure of options, making them a crucial part of the toolkit for many traders and investors.

II. Types of Options

A. Call Options

1. Definition and How They Work

A call option is a contract that gives the holder the right, but not the obligation, to buy a specific amount of an underlying asset (such as shares of a stock) at a predetermined price (the strike price) within a certain time period (until the expiration date). The buyer of a call option believes that the price of the underlying asset will increase by the expiration date, while the seller believes the price will remain the same or decrease.

2. Rights and Obligations of Call Option Buyers and Sellers

Call Option Buyers: They have the right to buy the underlying asset at the strike price before the contract expires. The maximum risk is the premium paid to the seller at the time of purchasing the contract. The potential profit is theoretically unlimited, as it’s based on the potential rise in the price of the underlying asset.
Call Option Sellers: Also known as the “writers” of the option, they have the obligation to sell the underlying asset at the strike price if the buyer decides to exercise the option. They receive the premium upfront, which is their maximum profit. Their potential loss can be significant as they would have to sell the asset at below its market price if it appreciates significantly.

B. Put Options

1. Definition and How They Work

A put option is a contract that gives the holder the right, but not the obligation, to sell a specific amount of an underlying asset at a predetermined price within a certain time period. The buyer of a put option believes that the price of the underlying asset will decrease by the expiration date, while the seller believes the price will remain the same or increase.

2. Rights and Obligations of Put Option Buyers and Sellers

Put Option Buyers: They have the right to sell the underlying asset at the strike price before the contract expires. The maximum risk is the premium paid to the seller at the time of purchasing the contract. The potential profit depends on the extent of the decrease in the price of the underlying asset.
Put Option Sellers: They have the obligation to buy the underlying asset at the strike price if the buyer decides to exercise the option. They receive the premium upfront, which is their maximum profit. Their potential loss can be significant as they would have to buy the asset at above its market price if it depreciates significantly.

C. Distinguishing Call and Put Options

The key difference between call and put options lies in the transaction they each enable. A call option gives the holder the right to buy an asset, while a put option gives the holder the right to sell an asset. Thus, if you believe the price of an asset will rise, you would purchase a call option. Conversely, if you believe the price of an asset will fall, you would purchase a put option. Similarly, if you believe the price of an asset will not rise significantly, you might sell a call option, and if you believe the price will not fall significantly, you might sell a put option.

III. Option Styles

A. American vs European Options

There are two main styles of options: American and European. These do not refer to geographic locations but rather to the terms and conditions of the contracts.

1. American Options

American options can be exercised at any point in time between the purchase of the option and the expiration date. This gives the holder more flexibility. Most exchange-traded options are American style.

2. European Options

European options, on the other hand, can only be exercised at the expiration date of the contract. While this may seem like a disadvantage, European options can often be less expensive than American options because they offer less flexibility.

B. The Importance of Option Styles in Option Trading

Understanding the difference between American and European options is crucial for option trading for several reasons.

1. Exercise Timing

The ability to exercise the option at any time with American options can be advantageous if the value of the underlying asset is likely to change significantly before the expiration date. However, early exercise will only be beneficial if the exercise profit exceeds the time value of the option.

2. Pricing

Option pricing models such as Black-Scholes are typically developed for European options due to their mathematical simplicity. American options, with the early exercise feature, require more complex valuation methods.

3. Availability

The type of options available can depend on the specific market. For instance, stock options traded on U.S. exchanges are usually American style, while options on many indices and futures are European style.

Understanding these differences and the implications of each type of option will help you better navigate the complexities of option trading. It’s also essential to always check the specifics of the contract you’re trading, as other styles of options exist, such as Bermudan options, which can be exercised on specific dates, and Asian options, which have payoffs determined by the average price of the underlying asset over a certain period.

IV. Understanding Option Contracts

A. Components of an Option Contract: Underlying Asset, Contract Multiplier

Underlying Asset: The underlying asset is the security upon which the option contract is based. It could be a stock, a bond, a commodity, an index, or a currency, among other things. The performance of this asset determines whether the holder of the option will exercise their right to buy (call option) or sell (put option) this asset.
Contract Multiplier: Also known as the contract size, the contract multiplier indicates the quantity of the underlying asset that is controlled by one option contract. For equity options, one contract usually represents 100 shares of the underlying stock. However, this could be different for options on other types of assets, like futures, indices, or currencies.

B. Option Symbol and How to Read It

An option symbol is a string of characters that represents specific option contracts listed on an exchange. While different exchanges may use slightly different formats, the option symbol typically includes information about the underlying asset, the expiration date, whether it’s a call or put option, and the strike price.

For instance, in the symbol “AAPL230120C00150000”:

AAPL is the ticker symbol for the underlying asset, in this case, Apple Inc.
230120 represents the expiration date, here, January 20, 2023.
C indicates that this is a Call option (P would be used for a Put).
00150000 is the strike price, here $150.00, represented without a decimal point.

Knowing how to read option symbols is important because it allows you to quickly identify the key terms of the option contract.

C. Option Chains and How to Use Them

An option chain, also known as an option matrix, is a listing of all available option contracts, both puts and calls, for a given security. It is a useful tool that helps traders and investors view all available option contracts and their prices for a given expiration date.

Components of an option chain typically include: the strike price, the contract name, the last traded price, the bid price, the ask price, the change for the day, the percent change, the volume of contracts traded, the open interest, and the implied volatility.

To effectively use an option chain:

Select the Asset: Start by selecting the underlying asset you’re interested in.
Choose the Expiry Date: Most option chains will let you select the expiry month/year. The expiration date is crucial as options are time-sensitive investments.
Analyze the Information: The chain will list call options on one side and put options on the other. The strike prices are listed down the middle. Examine the bid and ask prices, open interest, and volume to understand market sentiment.
Make Informed Decisions: Use the information to decide on the option contract that best suits your investment strategy or trading plan.

Option chains provide a snapshot of the trading activity for a particular option, giving investors key insights that can help inform their trading strategies. Understanding how to read an option chain is an essential skill for anyone interested in trading options.

V. Option Trading

A. The Mechanics of Buying and Selling Options

Buying Options: When you buy an option, you are purchasing a contract that gives you the right to either buy (call option) or sell (put option) the underlying asset at a set price within a specific time frame. As the buyer, you pay a premium to the seller for this right. If the price of the underlying asset moves in the direction that favors your contract (upwards for call options, downwards for put options), you can profit by exercising the option. Alternatively, you can also sell the option contract itself if it increases in value due to changes in the price of the underlying asset.
Selling Options: As a seller (or “writer”) of options, you receive the premium from the buyer. If you sell a call option, you are obligated to sell the underlying asset at the strike price if the buyer exercises the option. If you sell a put option, you are obligated to buy the underlying asset at the strike price if the buyer exercises the option. Sellers can profit if the option expires worthless (i.e., it is not in the buyer’s interest to exercise it), as they keep the premium.

B. Understanding Brokerage Requirements for Option Trading

Before you can start trading options, you must open an account with a brokerage that offers options trading. Brokerages will require you to fill out an options agreement form, which details your financial situation and investing experience, particularly in options. This is because options are complex financial instruments that carry a high degree of risk.

Different levels of options trading approval are available, and the level of approval granted typically corresponds to the risk associated with the strategies you are permitted to use. For instance, covered calls might require a lower level of approval because the risk is limited, while selling naked calls might require the highest level of approval due to the high risk involved.

Lastly, brokers will typically require a minimum balance to be maintained in your account for trading options, and this amount can vary widely between brokers.

C. The Concept of Open Interest and Volume in Option Trading

Open Interest: This refers to the total number of outstanding option contracts in the market at any given time. An increase in open interest means new contracts are being created, indicating more money entering the market. Conversely, a decrease suggests contracts are being closed, signaling money leaving the market. High open interest for a given option contract indicates a more active market, which can make it easier to enter or exit a position.
Volume: This refers to the number of options contracts traded in a day. Higher trading volume can indicate high interest in a particular option, and it can also make it easier to buy or sell the option.

Understanding these concepts is important for gauging market activity and liquidity. Both volume and open interest can provide insights into market sentiment. However, they should be used in conjunction with other indicators and not as standalone predictors of market direction.

VI. Risk and Reward in Option Trading

A. Understanding the Potential for Profit and Loss in Call and Put Options

Call Options: The potential profit for buyers of call options is theoretically unlimited, as it’s based on the potential rise in the price of the underlying asset. The maximum loss is limited to the premium paid for the option. For sellers of call options, the potential profit is limited to the premium received, but the potential loss can be substantial if the price of the underlying asset significantly increases.
Put Options: The potential profit for buyers of put options is capped at the strike price minus the premium paid, which would be realized if the price of the underlying asset fell to zero. The maximum loss is the premium paid for the option. For sellers of put options, the potential profit is limited to the premium received, while the potential loss can be significant if the price of the underlying asset significantly decreases.

B. Role of Options in Risk Management: Hedging

Options can play a crucial role in risk management through a strategy known as hedging. Hedging involves taking an offsetting position in a derivative in order to balance any losses gained on your investments. For instance, if you own a stock, you could buy a put option for that stock, which gives you the right to sell your shares at a set price. If the stock price falls, the put option will increase in value, offsetting some or all of the losses on the stock. Conversely, if you short a stock, you could buy a call option as a hedge to protect against the stock’s price increasing.

C. Speculation vs Hedging in Option Trading

While options can be used to manage risk, they can also be used for speculative purposes. Speculation involves making bets on the future price movements of an underlying asset. For instance, if you believe a stock’s price will rise, you could buy a call option on the stock. If the stock’s price does rise, you could exercise the option and buy the stock at the lower strike price, or sell the option for a profit.

While both speculation and hedging are common uses of options, they have different risk profiles. Hedging tends to reduce risk and protect existing profits, but it also limits potential gains and involves the cost of buying the options. Speculation can lead to high profits if the price moves in the direction you predicted, but it can also result in significant losses if the price moves in the opposite direction, including the potential loss of your entire investment if the option expires worthless. Therefore, it’s important to carefully consider your risk tolerance and investment goals when trading options.
