Main task: Grading

Risk management
Banks, asset mgmt, insurance, and large companies use
derivatives to hedge risk

Asset management
Asset management companies and the prop trading desk of some
banks use derivatives, e.g., to obtain leverage

Financial engineering
The largest, most dynamic financial institutions develop new
derivatives (or combine well-known ones in innovative ways)

Acquire knowledge of the functioning of the
markets for the main derivative instruments

Understand and apply the mathematical and
econometric tools used to formalize financial
problems and data analysis

Understand role of derivative instruments in the
market and as a corporate risk management tool

Develop and train critical thinking about financial
problems

J. Hull, “Options, Futures, and Other
Derivatives”, Prentice Hall, 10th edition
(other editions – within reason – also work!)

There’s a solutions manual – not mandatory,
but handy
Dear professor,
I am currently doing my internship at Goldman Sachs in
London in the Securities division and wanted to thank
you for the course in Options and Futures.
It has been very helpful and I am going back to the slides
you have provided us with.
The book by Hull is everywhere in the floor and it is
considered the “bible”!

Yes
▪ I will assume a solid knowledge of basic financial
mathematics, prob & stats, and calculus

Why?
▪ Valuing derivatives relies on mathematical techniques –
hard to say anything otherwise
▪ Many tasks you will face on the job require you to know
that math: using and/or writing computer code for pricing,
estimating VaR, designing new products, etc.
▪ Anyone can commit a formula to memory. Understanding
where it comes from is more challenging and rewarding!

Lectures

Case studies

Problem sets

“Take-home” mid-terms

Final exam

Wed & Thu

Check Blackboard regularly

Largely follow the textbook, but:
▪ There will be textbook material we don’t go over
in class – still exam material, unless otherwise
stated
▪ There will be enhancements

Hybrid mode

Participation: Making a comment…
< 1 time in 3 classes – don’t be too shy!
> 3 times in 1 class – let others speak too!

This course is hands-on
▪ Develop critical thinking
▪ Practice theory encountered in class
▪ Application to challenging real-world problems

Key component of business education worldwide

Great for practice

We will see some examples in class, but you
should practice on your own

Solving problems is how we learn

The spirit: Apply the tools we learn in class, to
find a solution to problems we have not seen
before

Two (2) “take-home” mid-terms
▪ Distributed via BlackBoard
▪ Per test: Two shots, over a one-week period

Can account for 30% of your grade, for the
first time you take the exam

Expiration: Any retake means you forfeit the
take-home mid-terms grades, and your grade
is 100% based on the exam

Partly about solving problems
▪ Similar to problem sets
▪ We will see some in class

Partly about applying the theory and
discussing its applications
▪ Similar to the kind of discussions we have in class
▪ Plenty of examples to develop intuition
Difficulty
Unreasonably difficult, impossible to pass
Ridicolously easy, guaranteed pass

First take of the exam:
max {
70% × Final exam score +
15% × Take-home mid-term #1 +
15% × Take-home mid-term #2 ;
100% × Final exam score

Any retake:
100% × Final exam grade
}

I can only write one for you if I know you –
participate in the class discussion!

I need time to write one!
▪ Ask me at least two months before your deadline

My letter will mention your performance on
my course (would not be credible otherwise)

The starting point should be your own idea

I’m happy to supervise empirical work
▪ Final paper ≠ Summary of a bunch of papers you
have read
▪ Get your hands dirty with data

Working on a BSc thesis will not affect your
grade on this course in any way


You want to buy a car. The dealer offers you a
price of $20,000

Place order today, take delivery in 3 months

Forward contract: you have the right and
obligation to buy in 3m

Let’s see your gains/losses in 3m

You don’t have the loan arranged, and offer
the dealer non-refundable $500 to hold the
price for 3 months

Option contract: you have the right, but not
the obligation, to buy in 3m

Let’s see your gains/losses
Derivative: A financial contract, between two or
more parties, whose value is derived from the
future value of an underlying asset
…in our case, underlying asset = the car

Forward
Buyer and seller agree today on the delivery
of a specified quantity and quality of an asset
at a future date, for a given price

Futures
Similar to forward, except it has a
standardized specification and is traded on
organized exchange. Profits and losses are
realized on a daily basis

Contracts for future delivery of
goods in ancient Mesopotamia
(~1700 BCE):
“Six shekels silver as a šu-lá
loan, Abuwaqar, the son of
Ibqu-Erra, received from
Balnumamhe. In the sixth
month he will repay it with
sesame according to the going
rate.”

Dojima Rice Exchange (1700s Japan)

Futures contracts on rice are traded; crucial for samurai
class, who were paid in rice

Authorities
repeatedly attempt
to shut it down, to
stop “gambling”

1730: Restrictions are
lifted and Dojima
exchange allows
futures trading

wants to pass it to another party willing to accept it
Ex. 1: Farmer who wants to protect future value of harvest (corn, grain…)
against price fluctuations
Ex. 2: Manufacturer who will need to buy a commodity (oil, coffee…) and
may buy options to stabilize production costs
Ex. 3: Portfolio manager who wants to guarantee a minimum rate of
return

Slightly more formalism. Introduce more
specialized concepts, to work with stochastic
processes in the Black-Scholes framework.
Some basic (as well as, time permitting, less
basic) numerical solutions.
Minimal mathematical formalism.
Focus on the building blocks:
• Pricing: Replicating and hedging portfolio
approaches
• Hedging: How to limit the exposure of your
investments to risk, using financial derivatives

Are derivatives “evil”? “Financial weapons of


Very versatile financial instruments

Sometimes traders who should hedge or
arbitrage turn into speculators

Using futures: You’re a US trader convinced
that BPD will appreciate in 2 months
▪ Buy £250,000 spot at $1.4470/£
▪ Buy 4 futures (1 contract = £62,500) at $1.4410/£;
margin account = $20,000

Using futures
$1.4470/£ × £250,000
Buy £250,000 spot
Spot price = $1.4470/£
Upfront investment
Buy 4 futures contracts
Futures price = $1.4410
$361,750
$20,000
Profit if future exchange
rate = $1.5/£
$13,250
$14,750
Profit if future exchange
rate = $1.4/£
–$11,750
–$10,250
Derivatives allow you to obtain leverage: Can take a large
speculative position (“exposure”) with a small initial investment

Using options: You have a hunch that IBM,
currently trading at $20, will go up
▪ Buy 100 shares (cost: $2,000)
▪ Buy 20 call option contracts with strike price
$22.5, premium $1, each giving right to buy 100
shares (cost: $2,000)

Using options: If IBM goes up to $27
▪ Profit from buying 100 shares:
100 × $27 − $20 = $700
▪ Profit from buying 20 option contracts:
20 × 100 × $4.50 − $2,000 = $7,000
☺

Using options: If IBM goes down to $15

▪ Loss from buying 100 shares:
100 × $15 − $20 = −$500
▪ Loss from buying 20 option contracts:
−$2,000
Leverage can generate large losses, despite a relatively small initial
investment
