Derivatives.

Perhaps no single word has a greater ability to strike fear in the hearts of CFA candidates. The readings on this topic are replete with graphs, formulas, all of which seem indecipherable, and gratuitous references to Greek letters.

However, it doesn’t need to be. In fact, it can be one of your strongest topics, as derivatives concepts are applicable to all 3 levels and don’t need memorization once you grasp the concept of how they work.

That’s why we have created our Cheat Sheet series of articles, which focuses on one specific topic area for one specific CFA Level. This cheat sheet focuses on CFA Level 1 derivatives.

More Cheat Sheets will be published in the coming weeks, sign up to our member’s list to be notified first.

By referring to the CFA Learning Outcome Statements (LOS), we prioritize and highlight the absolute key concepts and formula you need to know for each topic. With some tips at the end too!

Use the Cheat Sheets during your practice sessions to refresh your memory on important concepts.

Let’s learn this 🙂


CFA Level 1 Derivatives: An Overview

cfa level 1 derivatives cheat sheet

Similar to Alternative Investments, Derivatives is one of those topic that is worth mastering given its relatively light reading for its topic weight. At level 1, it is mostly introductory concepts, with particular attention needed on call and put options’ section, how they work and their payoff structure.

It is also present in all 3 levels of the CFA program, with a slight increase in topic weight for Level 2 and 3.

CFA Level 1 Derivatives’ topic weighting is 5-8%, which means 9-14 questions of the 180 questions of CFA Level 1 exam is centered around this topic.

For 2021’s curriculum, it is covered in Study Session 16, which includes Reading 48-49.

​The Level 1 curriculum is structured to give us a basic conceptual understanding of derivatives, how to value them, and how they can be used to manage risk.

Here’s a summary of CFA Level 1 Derivatives chapter reading:

Reading NumberSub-topicDescription
48Derivative Markets and InstrumentsThis reading covers what kinds of derivatives are out there, why are they needed and how they are priced.
49Basics of Derivative Pricing and ValuationDives into the detail of pricing and valuing various types of derivatives.

In a nutshell, the derivatives readings are about developing an understanding of what these instruments are, why you might want to use them, and what your net gain/loss would be over a range of possible outcomes.

Practically, derivatives are a useful risk management tool, which explains their growing popularity. So there’s a good chance that a better understanding of at least some parts of the derivatives material will be relevant to you job.

Options (calls and puts)

  • Option styles:
    • European options can only be exercised at expiration.
    • American options can be exercised anytime during the life of the option.
    • Thus, American options are more valuable than equivalent European options because it can be exercised anytime up to expiration.
    • American call option prices can differ from European call’s prices only if there are interim cashflows on the underlying asset, e.g. dividend or interest. These early cashflows are the only reason for an early exercise of a call.
    • American put option prices can differ from European put’s prices because the right to exercise early is valuable for puts. If the underlying stock pays a dividend, the put option holder should wait until expiration to exercise the option to ensure receipt of stock dividends as well.
  • Intrinsic value of European options:
    • European call = Max [0, ST – X]
    • European put = Max [0, X – ST]
  • Call option buyer and seller profit at expiration:
    • Call option buyer profit = Max [0, ST – X] – c0 , where c0 = option premium.
    • Call option seller profit = c0 – Max [0, ST – X]
  • Put option buyer and seller payoff at expiration:
    • Put option buyer profit = Max [0, X – ST] – p0 , where p0 = option premium.
    • Put option seller profit = p0 – Max [0, X – ST]

Forward contracts vs. Futures

  • A forward contract is an OTC derivative contract where 2 parties agree to exchange a specific quantity of asset for a fixed price at a future date.
  • Value of T-year forward contract (for a long position) at:
InitiationV0(T) = 0, because neither party pays any money to the other.
ExpirationVT(T) = ST – F0(T)
Time tVt(T) = St – PVt(benefit) + PVt(cost) – [F0(T)/(1+r)T-t]
  • Forward price of an asset, F0 = S0 (1+r)T – FVT(benefit) + FVT(cost)
  • Futures is similar to forward contract except it is standardized, exchange-traded, regulated, marked-to-market and settled daily, with a clearinghouse guarantee.
  • Forwards vs. futures prices:
    • If futures price positively (negatively) correlates with interest rates, futures price would be higher (lower) than forward’s price because there are intermediate cash flows on which interest can be earned on.
    • If interest rates are constant or have no correlation with futures prices, then futures and forward prices would be the same.

Forward Rate Agreements (FRA)

  • Forward contracts which have an interest rate (not an asset) as an underlying are called Forward Rate Agreements (FRAs).
  • FRAs allow us to lock in an interest rate today for a loan in the future to hedge against interest rate risk.
  • If LIBOR (reference rate) > FRA rate at expiration, the long benefits.
  • If LIBOR (reference rate) < FRA rate at expiration, the short benefits.

Interest rate swaps

  • The value of a swap at initiation is usually 0.
  • If interest rate increases (decreases) after swap initiation, the swap would have a positive value for fixed-rate payer (floating-rate payer).
  • An interest rate swap can be viewed as a series of combined FRAs.

Moneyness of an option

Put-call parity for European options

Fiduciary call = protective put

c0 + X/(1+r)T = p0 + s0


Put-call-forward parity for European options

c0 + X/(1+r)T = p0 + F0(T)/(1+r)T



CFA Level 1 Derivatives Tips

CFA Level 1 Derivatives: Our Cheat Sheet 3

There is a good chance that the majority of exam questions on this topic will be qualitative, so your focus when studying the Level 1 derivatives material should be on grasping concepts rather than committing formulas to memory and then working them through.

Once you have a solid command of the rationale for using various derivatives, the formulae will come to you on the basis of logic and understanding rather than on the basis of rote memorization.

​That may sound like a poor attempt at finding Zen in a most un-Zen-like topic, but it really does help to take a step back and look at the material in these readings fits into the bigger picture of the CFA curriculum.

Here are two examples, one qualitative and one quantitative, of questions that are representative of what you can expect to see on exam day.

Qualitative example:

A fiduciary call strategy most likely involves establishing a:

A. long position in a risk-free bond.
Blong position in the underlying asset.
C. short position in a call option contract.

Choice A is the correct answer because a fiduciary call strategy is executed by taking a long position in a call option contract and lending at the risk-free rate (or taking a long position in a risk-free bond).

According to put-call parity, a fiduciary call strategy provides equivalent payoffs to a protective put strategy, which is executed by combining a long position in an underlying asset with a long position in a put option contract based on that asset.

Quantitative example:

An investor who holds 100 shares of ABC stock, which currently trades at $15.50 per share, decides to implement a covered call strategy using a call option contract that grant the long party the right to purchase 100 shares of ABC for $16.00 per share. This contract is priced at $1.50 per share. If ABC shares are trading for $17.00 at the time the contract expires, the payoff to this covered call strategy on a per share basis is closest to:

A. $1.00.
B. $2.00.
C. $3.00.

Choice B is the correct answer because a covered call strategy is executed by taking a long position in an underlying asset and a short position in a call option contract based on that asset.

The formula for calculating payoff for a covered call is as follows:

Π = ST – S0 – max(0,ST – X) + c0

where
​Π = profit from covered call strategy
ST = price of the underlying asset at time T
S0 = price of the underlying asset at time 0
X = call option exercise price
c0 = call option price at time 0In this example,

Π = $17.00 – $15.50 – max(0,$17.00 – $16.00) + $1.50
= $17.00 – $15.50 – $1.00 + $1.50
= $2.00

Choice A is incorrect because it assumes that the investor has gained $1.50 from the appreciation of the underlying asset, but suffered a net loss of $0.50 by taking a long call position when a covered call strategy requires a short call position.

Choice C is incorrect because it fails to account for the fact that the investor suffered a loss of $1.00 as a result of having taken a short call position.
