Introduction to Option Valuation
In the world of derivative securities, option valuation is crucial for FINRA Series 7 candidates. This chapter dives into understanding how options are priced, focusing on intrinsic value, time value, and volatility impact. Equipped with interactive quizzes, this article aims to solidify your grasp of option valuation concepts, ensuring you’re prepared for the Series 7 exam.
Understanding Intrinsic Value
Intrinsic value is a key component in option valuation. It represents the difference between the option’s strike price and the underlying asset’s price when it is profitable to exercise the option. For a call option, intrinsic value equals the underlying price minus the strike price, provided this value is positive. For a put option, it is the strike price minus the underlying asset’s price. When options have intrinsic value, they are described as being “in the money.”
For a call option:
$$ \text{Intrinsic Value} = \max(0, \text{Underlying Price} - \text{Strike Price}) $$
For a put option:
$$ \text{Intrinsic Value} = \max(0, \text{Strike Price} - \text{Underlying Price}) $$
The Role of Time Value
Time value refers to the portion of the option’s premium that exceeds its intrinsic value. It accounts for the possibility that the option could become profitable before expiration. Time value decreases as the expiration date approaches, a phenomenon known as time decay or theta.

Volatility Impact on Option Pricing
Volatility significantly impacts an option’s price. Higher volatility in the underlying asset increases the option premiums due to the greater uncertainty and potential for large price movements, enhancing the likelihood of profitable scenarios.
Conclusion
Mastering option valuation concepts such as intrinsic value, time value, and the effects of volatility is vital for the Series 7 exam. Understanding these elements will enable candidates to effectively assess and price options, ensuring readiness for questions on this topic.
Glossary
- Intrinsic Value: The profit that would be realized if the option were exercised immediately.
- Time Value: The portion of the option’s price that reflects the time remaining until expiration.
- Volatility: The degree of variation of a trading price series over time.

### What is the intrinsic value of a call option with a strike price of $50 and an underlying stock price of $60?
- [x] $10
- [ ] $5
- [ ] $0
- [ ] $20
> **Explanation:** The intrinsic value is the underlying stock price ($60) minus the strike price ($50), equaling $10.
### Which factor does not directly affect the intrinsic value of an option?
- [ ] Strike price
- [ ] Underlying asset price
- [x] Time to expiration
- [ ] Option type
> **Explanation:** Time to expiration affects the time value, not the intrinsic value.
### If an option's premium is $8 with an intrinsic value of $5, what is the time value?
- [x] $3
- [ ] $5
- [ ] $8
- [ ] $13
> **Explanation:** The time value is the premium ($8) minus the intrinsic value ($5), equaling $3.
### How does increased volatility affect an option's premium?
- [x] Increases it
- [ ] Decreases it
- [ ] Has no effect
- [ ] Makes it zero
> **Explanation:** Higher volatility increases potential price movements, raising option premiums.
### An option with no intrinsic value is said to be:
- [x] Out of the money
- [ ] At the money
- [x] Underpriced
- [ ] Above the money
> **Explanation:** An option without intrinsic value (e.g., strike price not reached) is out of the money.
### What happens to an option’s time value as it nears expiration?
- [x] Decreases
- [ ] Increases
- [ ] Stays the same
- [ ] Doubles
> **Explanation:** The time value decreases due to time decay, reaching zero at expiration.
### If a put option has a strike price of $45 and the stock price is $40, the option is:
- [x] In the money
- [ ] Out of the money
- [x] Underpriced
- [ ] Unavailable
> **Explanation:** A put option is in the money when the strike price is above the stock price.
### For a stock with high volatility, the option premiums are generally:
- [x] High
- [ ] Low
- [ ] Unaffected
- [ ] Zero
> **Explanation:** High volatility implies higher premiums due to greater potential for price change.
### Which scenario most affects an option's time value?
- [x] Longer time until expiration
- [ ] Lower strike price
- [ ] Higher dividend yield
- [ ] Lower interest rate
> **Explanation:** Time value increases with more time until expiration.
### True or False: The only component of an option's premium that changes over time is intrinsic value.
- [ ] True
- [x] False
> **Explanation:** While intrinsic value can change with the underlying asset price, time value is primarily affected by the passage of time.
Final Summary
In conclusion, understanding option valuation components—intrinsic and time values, and volatility impact—prepares you for critical aspects of the Series 7 exam. Using the quizzes and resources provided, you can confidently approach option-related questions.
