## Per-objective worked-example outlines

For each learning objective on Option Pricing Fundamentals, here is the approach an exam item would test — the setup, the ordering of your reasoning, and the formula or identity you need to bring to the page. Approaches, not full solutions, by design. Verify against the current [soa.org](https://www.soa.org/) syllabus before your sitting.

### Apply put-call parity to relate European call and put prices

Setup

A European call price, strike, time to maturity, current stock price, and risk-free rate are given, and you must find the corresponding put price.

Approach

Use put-call parity: C - P = S - K e^{-rT} (for non-dividend stock) or C - P = S e^{-qT} - K e^{-rT} (with continuous dividend yield q). Solve for the unknown. Check that the put price is non-negative; if not, recheck the inputs and parity sign.

Key identity

C - P = S e^{-qT} - K e^{-rT} (European, continuous dividend q).

### Price options using one-period and multi-period binomial models

Setup

A stock can move up by u or down by d in each period with given probabilities, and you must price a European call or put using the binomial model.

Approach

Compute the risk-neutral probability p\* = (e^{rh} - d) / (u - d) per period. Walk back from terminal payoffs using p\* and discounting by e^{-rh} per step. For American options, take the max of the discounted expected continuation value and the exercise value at each node. Match h, u, d, and r to a consistent time unit.

Key identity

p\* = (e^{rh} - d) / (u - d); option price = e^{-rh} (p\* V\_u + (1 - p\*) V\_d).

### Use the Black-Scholes formula to price European calls and puts

Setup

Stock price, strike, time, volatility, risk-free rate, and dividend yield are given and you must price a European call or put.

Approach

Compute d\_1 = \[ln(S/K) + (r - q + σ^2/2) T\] / (σ √T) and d\_2 = d\_1 - σ √T. Look up N(d\_1) and N(d\_2) from a standard normal table. Call price = S e^{-qT} N(d\_1) - K e^{-rT} N(d\_2). Use put-call parity to get the put price if needed.

Key identity

C = S e^{-qT} N(d\_1) - K e^{-rT} N(d\_2); d\_1, d\_2 as above.

## Common exam traps on Option Pricing Fundamentals

Recurring patterns where candidates lose points on Option Pricing Fundamentals-style items. Each entry pairs the trap with the fix.

Trap

Using real-world probabilities instead of risk-neutral probabilities in the binomial pricer.

Fix

The actual probability of up/down is irrelevant; use p\* derived from the no-arbitrage condition.

Trap

Forgetting the dividend yield in put-call parity or Black-Scholes.

Fix

Include e^{-qT} on the stock side whenever a dividend yield is given.

Trap

Mixing time units between volatility (annual) and step size (often shorter).

Fix

Express σ, r, q, and h in consistent annualized units before plugging into formulas.

Trap

Pricing an American option with the European formula.

Fix

For American puts (and rarely American calls), step through the tree comparing exercise vs continuation at every node.
