Authoritative Rule Summary (Basel III)

Under Basel III (GARP / Basel Committee), option Valuation: Models, Implied Volatility, and Greeks establishes the authoritative rules tested on the GARP FRM® Part I. Explores binomial and Black-Scholes-Merton models for option valuation, the concept of implied volatility, and the practical application of option Greeks. VoraPrep verifies every threshold, worked table, and practice question below against the current GARP FRM® Part I blueprint.

A portfolio manager holds a long position in a call option and has established a delta-neutral hedge. If the underlying stock price subsequently experiences a significant decrease, what action would most likely be required to maintain the delta-neutral position?

Worked Practitioner Scenario

Practitioner Application: Option Valuation: Models, Implied Volatility, and Greeks

A portfolio manager is evaluating a European call option and needs to understand its sensitivity to underlying price changes, volatility, and time decay. They must select the appropriate valuation model and interpret its risk metrics to make an informed hedging decision, aligning with GARP FRM Learning Objectives related to option pricing and risk management.

  1. Option valuation models provide theoretical prices for derivatives, enabling risk managers to assess fair value and associated risks. The binomial tree model and the Black-Scholes-Merton (BSM) model are fundamental approaches, each with distinct assumptions and applications.
  2. Binomial Tree Model This is a discrete-time model that assumes the underlying asset price can only move to one of two possible prices (up or down) during each period. It uses a risk-neutral valuation approach, meaning the expected return on all assets is the risk-free rate. It's particularly useful for American options where early exercise is possible, as it can be adapted to evaluate early exercise opportunities.
Black-Scholes-Merton (BSM) Model The BSM model is a continuous-time model for pricing European options on non-dividend-paying stocks. Its core assumptions include: 1. The underlying asset price follows a geometric Brownian motion with constant volatility. 2. The risk-free rate is constant. 3. No dividends are paid during the option's life. 4. No transaction costs or taxes. 5. Continuous trading. 6. Options are European-style.
Exam Watchouts & Statutory Boundaries

Common GARP FRM® Part I Distractors on Basel III

  • 1⚠️ Exam trap: Confusing European and American options when applying models. The BSM model is strictly for European options. While a binomial model can price both, using BSM for an American option that has significant early exercise value will undervalue it.
  • 2Binomial vs. BSM: Use binomial for American options and where early exercise or discrete events (e.g., dividends) are relevant. Use BSM for European options on non-dividend-paying assets.
  • 3Implied Volatility: It's the market's forward-looking expectation of volatility, derived from an option's market price using a pricing model.
  • 4- Delta: Sensitivity to underlying price change (first-order).
  • 5- Gamma: Sensitivity of Delta to underlying price change (second-order).

How is Basel III tested on the GARP FRM® Part I?

⚠️ Exam trap: Confusing European and American options when applying models. The BSM model is strictly for European options. While a binomial model can price both, using BSM for an American option that has significant early exercise value will undervalue it. Binomial vs. BSM: Use binomial for American options and where early exercise or discrete events (e.g., dividends) are relevant. Use BSM for European options on non-dividend-paying assets.
