Premium income is a form of income received by an investor who sells a put option or a call option. This type of income is prevalent in options trading and represents the price paid by the buyer of the option to the seller for the rights conveyed by the option.
Understanding Premium Income
Definition of Premium Income
In options trading, premium income refers to the monetary compensation received by the seller (writer) of an options contract from the buyer. When an investor sells an option, they receive a premium which compensates them for the obligation they must fulfill if the option is exercised by the buyer.
Types of Options
Call Option
A call option gives the buyer the right, but not the obligation, to buy an underlying asset at a specified price (strike price) before or at the option’s expiration date. The seller, in this case, receives a premium and is obligated to sell the asset if the option is exercised.
Put Option
A put option gives the buyer the right, but not the obligation, to sell an underlying asset at a specified price (strike price) before or at the option’s expiration date. The seller receives a premium and is obligated to buy the asset if the option is exercised.
Special Considerations
Factors Affecting Premium
The premium of an option is influenced by multiple factors:
- Intrinsic Value: The difference between the strike price and the current price of the underlying asset.
- Time Value: The longer the time until expiration, the higher the premium.
- Volatility: Greater volatility generally leads to higher premiums.
- Interest Rates: Changes in interest rates can affect option prices.
- Dividends: Expected dividends can have an impact on the option’s premium.
Risks for Option Writers
While premium income can be lucrative, it involves significant risks:
- Obligation to Fulfill Contract: The seller must fulfill the contract if the buyer exercises the option.
- Potential Losses: The potential loss can be significant, particularly for uncovered call options.
Examples
-
Call Option Example: An investor sells a call option for a stock at a strike price of $50, expiring in one month, receiving a premium of $2 per share. If the stock price stays below $50, the option expires worthless, and the seller retains the premium as income.
-
Put Option Example: An investor sells a put option for a stock at a strike price of $45, expiring in two months, and receives a premium of $1.50 per share. If the stock price remains above $45 until expiration, the option expires worthless, and the seller keeps the premium.
Historical Context
Options trading has been a part of financial markets since the early 17th century when options on commodities were traded in European communities. The formalized and regulated trading of options began with the establishment of the Chicago Board Options Exchange (CBOE) in 1973.
Applicability
Premium income is applicable for:
- Income Generation: Investors use it for additional income streams.
- Strategic Positioning: It can support various trading strategies such as covered calls and protective puts.
Comparisons
Premium Income vs. Dividends
- Source: Premium income arises from selling options, whereas dividends come from company earnings distributed to shareholders.
- Predictability: Dividends are usually predictable and scheduled, while premium income depends on market conditions and option-selling opportunities.
Premium Income vs. Interest Income
- Nature: Premium income is derived from market activities, while interest income comes from lending or deposits.
- Risk: Generally, premium income involves higher risks compared to the regular interest income.
Related Terms

- Protective Put: A strategy where an investor holds a long position in an asset and buys put options to protect against potential losses.
