Options

What Are Options?

Options are a type of financial derivative contract that gives the buyer the right, but not the obligation, to buy or sell an underlying asset at a predetermined price, known as the strike price, on or before a specific expiration date. For this right, the buyer pays a non-refundable fee called a premium to the seller. Options are versatile instruments used within the broader financial category of derivatives for various purposes, including income generation, speculation, and hedging existing portfolio positions.

History and Origin

The concept of options contracts can be traced back to ancient times, with one of the earliest recorded instances involving the philosopher Thales of Miletus in ancient Greece, who reportedly secured rights to olive presses based on a predicted bountiful harvest.³ However, the modern, standardized options market saw its true beginning in the United States with the establishment of the Chicago Board Options Exchange (CBOE) in 1973.² Prior to this, options were traded over-the-counter (OTC), lacking the transparency and standardization necessary for widespread adoption. The CBOE's creation formalized options trading, providing a regulated platform and standardized contracts that allowed for greater liquidity and accessibility.¹ The introduction of the Black-Scholes option pricing model in 1973 further revolutionized the understanding and valuation of options, contributing significantly to the growth and complexity of the options market.

Key Takeaways

• Options grant the holder the right, but not the obligation, to transact an underlying asset.
• The two primary types are call options (right to buy) and put options (right to sell).
• Options trading involves a buyer who pays a premium and a seller who receives it.
• They are financial derivatives used for hedging, speculation, or generating income.
• The value of an option is influenced by factors such as the underlying asset's price, volatility, time to expiration, and interest rates.

Interpreting Options

Understanding options involves recognizing the interplay of several factors. A call option gains value when the underlying asset's price increases, while a put option gains value when the underlying asset's price decreases. The difference between an option's strike price and the current market price of the underlying asset determines its intrinsic value. Beyond intrinsic value, options also possess time value, which erodes as the expiration date approaches, a phenomenon known as time decay. Traders and investors interpret options based on their market outlook, deciding whether to buy or sell calls or puts to align with expectations of price movements in the underlying asset.

Hypothetical Example

Consider an investor who believes that Company ABC's stock, currently trading at $100 per share, will increase significantly in the next three months. Instead of buying 100 shares for $10,000, they could buy one ABC call option contract with a strike price of $105 and an expiration three months out, for a premium of $5 per share (or $500 for the contract, as one options contract typically covers 100 shares).

• Scenario 1: Stock Rises If, at expiration, ABC's stock rises to $120, the investor can exercise their option to buy 100 shares at $105. They then immediately sell these shares in the market at $120, making a gross profit of $15 per share ($120 - $105 = $15). After deducting the $5 premium paid, the net profit is $10 per share, or $1,000 for the contract.
• Scenario 2: Stock Falls or Stays Below Strike If, at expiration, ABC's stock is at $100 or below the $105 strike price, the option expires worthless. The investor's loss is limited to the $500 premium paid, unlike direct stock ownership where losses could be greater if the stock price drops significantly.

This example illustrates how options can provide leverage and limited risk compared to direct stock purchases.

Practical Applications

Options are integral to various financial strategies across different market participants. Investors use them for risk management by hedging existing stock positions against potential downturns. For instance, owning a put option can protect a stock portfolio from significant losses, similar to an insurance policy. Speculators utilize options to profit from anticipated price movements in an underlying asset, often with less capital outlay than directly buying or shorting the asset. Income-oriented investors might sell options to collect premiums, a strategy commonly seen with covered calls or cash-secured puts. Options are traded on regulated exchanges, such as Cboe Global Markets, which offers a range of options products including equity, index, and exchange-traded product options. The Securities and Exchange Commission (SEC) provides guidance for investors considering options, highlighting their complexity and potential risks.

Limitations and Criticisms

Despite their versatility, options come with limitations and criticisms. Their valuation can be complex, influenced by multiple variables, and subject to theoretical models that may not perfectly reflect real-world market conditions. For example, while the Black-Scholes model revolutionized options pricing, it operates under certain assumptions (like constant volatility) that are not always met in dynamic markets. [https://www.frbsf.org/economic-research/publications/economic-letter/1997/april/the-black-scholes-formula-and-options-markets/] Options can experience rapid time decay, especially as they near expiration, leading to losses even if the underlying asset moves in the anticipated direction but not quickly enough. Furthermore, while options offer leverage, this leverage also amplifies potential losses for options sellers, as their maximum loss can theoretically be unlimited for uncovered call options. The intricate nature of options strategies means they may not be suitable for all investors, particularly those new to financial markets, due to the need for a thorough understanding of their mechanics and associated risks.

Options vs. Futures Contracts

Options and futures contracts are both financial derivatives, but they differ fundamentally in their obligations. An option provides the holder the right, but not the obligation, to buy or sell an underlying asset at a specified price before or on a certain date. The decision to exercise the option is discretionary. In contrast, a futures contract is an obligation for both parties: the buyer is obligated to purchase, and the seller is obligated to deliver, a specific quantity of an underlying asset at a predetermined price on a future date. The buyer of a futures contract does not pay a premium upfront but instead typically posts margin. This distinction means that options offer flexibility and limited downside risk (to the premium paid) for the buyer, while futures contracts carry full price risk and require settlement regardless of the market price at expiration.

FAQs

What are the two main types of options?

The two main types are call options and put options. A call option gives the holder the right to buy the underlying asset, while a put option gives the holder the right to sell it.

What is options premium?

The premium is the price a buyer pays for an options contract. It is the cost of acquiring the right that the option provides and is non-refundable.

How do options expire?

Options contracts have a set expiration date. On or before this date, the holder can choose to exercise the option if it is profitable, or let it expire worthless. If an option expires worthless, the buyer loses the premium paid.

Can options be used for hedging?

Yes, options are widely used for hedging. For example, an investor owning shares of a stock can buy put options on that stock to protect against a potential decline in its price, thereby limiting their downside risk.
