What Is Call Premium?

Call premium refers to the price paid by the buyer of a call option to the seller (or writer) for the right, but not the obligation, to purchase an underlying asset at a predetermined strike price within a specific period or on a specific date⁶⁴. In the context of options, the call premium is essentially the market price of the option contract itself⁶³.

Beyond options, the term "call premium" also applies to fixed-income securities such as callable bonds or preferred stock. In this instance, it is the amount above the par value that an issuer pays to bondholders when redeeming the security before its scheduled maturity date⁶². This compensation is intended to offset the lost future income and reinvestment risk for the bondholders⁶⁰, ⁶¹.

Call premium falls under the broader financial category of derivatives and fixed-income analysis.

History and Origin

The concept of options, and by extension the idea of a premium for a future right, has ancient roots, with mentions dating back to the Greek philosopher Thales of Miletus around 332 B.C.⁵⁸, ⁵⁹. However, the modern era of options trading began much later. Prior to 1973, options were primarily traded over-the-counter (OTC) with unstandardized terms, making them illiquid and less accessible⁵⁶, ⁵⁷.

A significant turning point arrived with the establishment of the Chicago Board Options Exchange (Cboe) in 1973⁵⁵. Cboe introduced standardized option contracts, centralizing liquidity and facilitating widespread adoption⁵³, ⁵⁴. On its opening day, April 26, 1973, Cboe traded call options on only 16 underlying stocks⁵¹, ⁵². Alongside Cboe, the Options Clearing Corporation (OCC) was formed, providing a central clearinghouse that guaranteed the performance of these contracts and significantly reducing counterparty risk for traders⁴⁹, ⁵⁰. This standardization and centralized clearing revolutionized the market, making options a more legitimate and widely used financial instrument⁴⁸. Cboe Global Markets celebrated its 50th anniversary in 2023, reflecting its long-standing impact on the financial landscape⁴⁵, ⁴⁶, ⁴⁷.

Key Takeaways

• The call premium is the price paid by a buyer for a call option, granting the right to purchase an underlying asset at a set strike price.
• For callable bonds, the call premium is the extra amount paid by the issuer to redeem the bond before maturity, compensating bondholders for lost future income⁴³, ⁴⁴.
• Option premiums are influenced by factors such as the underlying asset's price, strike price, expiration date, and implied volatility⁴².
• The total option premium's value is composed of its intrinsic value and time value⁴¹.

Formula and Calculation

For options, the option premium is typically determined by a combination of factors, including its intrinsic value and time value, as well as implied volatility³⁸, ³⁹, ⁴⁰. The general relationship can be expressed as:

Option Premium = Intrinsic Value + Time Value + Volatility Value³⁷

Where:

• Intrinsic Value: For a call option, this is the amount by which the underlying asset's current price exceeds the strike price³⁵, ³⁶. If the underlying price is below the strike price, the intrinsic value is zero³⁴.
• Time Value: This represents the portion of the premium that accounts for the possibility of the underlying asset's price moving favorably before the expiration date³², ³³. The longer the time to expiration, the greater the time value³⁰, ³¹.
• Volatility Value: This component reflects the market's expectation of how much the price of the underlying asset will fluctuate²⁸, ²⁹. Higher expected volatility generally leads to a higher option premium²⁷.

For a callable bond, the call premium is calculated as:

For example, if a bond with a par value of $1,000 has a call price of $1,050, the call premium would be $50²⁵, ²⁶.

Interpreting the Call Premium

When evaluating a call option, the call premium is the direct cost of acquiring the right to buy the underlying asset. A higher call premium can indicate several things: greater time remaining until the expiration date, higher implied volatility of the underlying asset, or that the option is significantly "in-the-money" (meaning the underlying asset's price is well above the strike price)²⁴. Traders assess the call premium in relation to their expectations for the underlying asset's price movement and the time horizon of their trade.

For callable bonds, the call premium represents the issuer's cost for the flexibility to redeem the bond early. A higher call premium on a bond implies greater compensation for the bondholders if the bond is called²², ²³. This compensation aims to mitigate the reinvestment risk faced by investors who would need to find new investments, potentially at lower interest rates, if their bond is redeemed early²⁰, ²¹.

Hypothetical Example

Consider an investor, Alice, who believes that Company XYZ's stock, currently trading at $100 per share, will rise significantly in the next three months. Alice decides to purchase a call option on Company XYZ with a strike price of $105 and an expiration date three months from now. The quoted call premium for this option contract is $3 per share.

Since one option contract typically represents 100 shares, Alice would pay a total call premium of $300 ($3 per share x 100 shares) to acquire this right. This $300 is the cost of entering the trade.

Two months later, Company XYZ's stock price soars to $115 per share. Alice's call option is now "in-the-money" because the market price ($115) is above the strike price ($105). She can choose to exercise her option, buying 100 shares at $105 each, and then immediately sell them in the market at $115 per share.

Her gross profit from the stock transaction would be ($115 - $105) * 100 = $1,000. After subtracting the $300 call premium she paid, Alice's net profit is $700 ($1,000 - $300).

If, however, Company XYZ's stock price had fallen to $95 per share by the expiration date, her option would be "out-of-the-money." In this scenario, she would not exercise the option, and the call premium of $300 would be her maximum loss.

Practical Applications

Call premiums are central to various aspects of finance and investing:

• Options Trading Strategies: Investors and traders utilize call premiums in numerous strategies, including buying calls for speculative upside, selling covered calls to generate income, or using complex derivatives strategies like spreads and combinations. The cost of the call premium directly impacts the profitability and risk profile of these strategies.
• Hedging: Companies and investors use call options, and thus pay call premiums, to hedge against potential increases in the price of an underlying asset they may need to purchase in the future. For example, an airline might buy call options on jet fuel to cap its potential costs.
• Callable Securities Analysis: For investors in [fixed-income securities](https://diversification.com/term/fixed-income-s ecurities), understanding the call premium embedded in a callable bond is crucial. It informs them about the potential compensation they would receive if the bond is redeemed early, which is particularly relevant when interest rates decline and issuers seek to refinance debt at lower costs¹⁹.
• Risk Management: Regulators and financial institutions monitor trends in options trading and associated premiums. For instance, the increased popularity of short-dated options, such as zero-days-to-expiration (0DTE) contracts, has prompted examination of potential risks by Wall Street firms and clearing houses due to their high-risk nature¹⁸. The Federal Reserve Bank of New York also examines how interconnectedness between banking and non-banking sectors through derivatives might pose systemic risk¹⁷.

Limitations and Criticisms

While call premiums are fundamental to options trading and callable bonds, they come with certain limitations and criticisms:

• Complexity in Option Pricing: Calculating an option premium precisely can be complex, influenced by multiple dynamic factors beyond just intrinsic value and time value, such as implied volatility, interest rates, and dividends¹⁵, ¹⁶. The theoretical models used, like Black-Scholes, rely on assumptions that may not always hold true in real-world markets¹⁴. This complexity can make it challenging for less experienced investors to accurately assess the fair value of a call premium.
• Time Decay: A significant criticism for option buyers is the effect of time decay, or theta. The time value component of the call premium erodes as the expiration date approaches, meaning that even if the underlying asset's price remains stable, the option's value will decrease¹³. This makes options a depreciating asset for buyers who are not actively managing their positions.
• Risk for Writers: For sellers (writers) of call options, while they collect the call premium upfront, they face potentially unlimited losses if the price of the underlying asset rises significantly above the strike price. This asymmetric risk profile is a critical consideration for option writers, particularly in "naked" call positions where they do not own the underlying asset.
• Reinvestment Risk for Bondholders: In the context of callable bonds, while the call premium offers compensation, it does not fully eliminate the reinvestment risk. If a bond is called when interest rates are low, the bondholders may struggle to find new investments that offer a comparable yield¹¹, ¹².

Call Premium vs. Option Price

While often used interchangeably in casual conversation, "call premium" is synonymous with the "option price" in the context of options trading. The option price is the total amount that the buyer pays to the seller for an option contract¹⁰. This price, or call premium, is composed of two primary elements: intrinsic value and time value⁹.

Confusion may arise because "premium" is also used in other financial contexts, such as the call premium paid for callable bonds, which is distinct from an option contract's price. For options, however, the terms are interchangeable.

FAQs

What is the primary purpose of a call premium for an option?

The primary purpose of a call premium for an option is the price paid by the buyer to the seller for the right to purchase the underlying asset at a specified strike price before or on the expiration date⁷. It compensates the seller for the risk undertaken and the potential obligation to deliver the asset.

How does the call premium for a callable bond differ from that of a call option?

For a callable bond, the call premium is an additional amount paid above the par value by the issuer to bondholders when the bond is redeemed early⁶. This is distinct from a call option's premium, which is the price paid by an option buyer to gain the right to buy an underlying asset.

What factors influence the size of a call premium for an option?

The size of a call premium for an option is influenced by several factors, including the price of the underlying asset relative to the strike price (intrinsic value), the time remaining until the expiration date (time value), and the expected volatility of the underlying asset (implied volatility)³, ⁴, ⁵. Interest rates and dividends can also play a role, though generally to a lesser extent¹, ².
