Derivatives Flashcards
What is a Derivative instrument?
A derivative instrument is an investment transaction in which the parties’ gain or loss is derived from some other economic event (i.e. the price of a given stock, foreign currency exchange rate or the price of a certain commodity)
One party enters into the transaction to speculate (incur risk) and the other enters into it to hedge (avoid risk)
Derivatives are a type of financial instrument, along with cash, accounts receivable, notes receivable, bonds, preferred shares, common shares, etc.
Derivatives are not claims on business assets (i.e. those represented by equity securities)
What is a Covered option?
A covered option is one in which the seller (writer) already has possession of the underlying
What is Naked (uncovered) option?
A naked (uncovered) option is a speculative instrument; since the writer does not hold the underlying, they may have to acquire it at an unknown price in the future to satisfy their obligations under the option contract
What is an Index option?
An index option is an option whose underlying asset is a market index. If exercised, settlement is made by cash since delivery of the underlying is impossible
What are Long-term equity anticipation securities (LEAPS)?
Long-term equity anticipation securities (LEAPS) are examples of long-term stock option or index options (with expiration dates up to 3 years away)
What are Foreign currency options?
Foreign currency options give the holder the right to buy a specific foreign currency at a designated exchange rate
What is a Call option?
A call option gives the buyer (holder) the right to purchase (i.e. the right to “call” for) the underlying asset (stock, currency, commodity, etc.) at a fixed price
A call option represents a long position to the holder because the holder benefits from a price increase
The seller (writer) of a call option obviously hopes the price of the underlying will remain below the exercise price since they must make the underlying available to the holder at the stick price, regardless of how much the seller must pay to obtain it. The seller of a call option is thus taking a short position
What does it mean when a call option is “in-the-money”?
If the price of the underlying rises above the exercise price, the option is said to be “in-the-money”
The holder can exercise their option and buy the underlying at a bargain price
What does it mean when a call option is “out-of-the-money”?
If the value of the underlying is less than the exercise price of the option, the option is “out-of-the-money” or NOT worth exercising
What does it mean when a call option is “at-the-money”?
If the value of the underlying is equal to the exercise price of the option, the option is said to be “at-the-money”
How do you calculate the buyer (holder) gain/loss on a call option?
(Long position)
The buyer’s gain (loss) necessarily mirrors the seller’s loss (gain). The amount of gain and loss on a call option can be calculated as follows:
= Units of underlying x (Excess of market price over exercise price - Option price)
How do you calculate the seller (writer) gain/loss on a call option?
(Short position)
The buyer’s gain (loss) necessarily mirrors the seller’s loss (gain). The amount of gain and loss on a call option can be calculated as follows:
= Units of underlying x (Option price - Excess of market price over exercise price)
What is a Put option?
A put option gives the buyer (holder) the right to sell (i.e. the right to “put” onto the market) the underlying asset (stock, currency, commodity, etc.) at a fixed price
A put option represents a short position to the holder because the holder benefits from a price decrease
The seller (writer) of a put option obviously hopes the price of the underlying will remain above the exercise price, since they must buy from the holder at the strike price, regardless of the fact that the same underlying can be obtained for less than the open market. The seller of a put option is thus taking a long position
What does it mean when a put option is “in-the-money”?
If the price of the underlying falls below the exercise price, the option is said to be “in-the-money”
The holder can exercise their option and compel the counterparty to buy the underlying at a price higher than that prevailing in the market
What does it mean when a put option is “out-of-the-money”?
If the value of the underlying is higher than the exercise price of the option, the option is “out-of-the-money” or NOT worth exercising
What does it mean when a put option is “at-the-money”?
If the value of the underlying is equal to the exercise price of the option, the option is said to be “at-the-money”
How do you calculate the buyer (holder) gain/loss on a put option?
(Short position)
The buyer’s gain (loss) necessarily mirrors the seller’s loss (gain). The amount of gain and loss on a put option can be calculated as follows:
= Units of underlying x (Excess of exercise price over market price - Option price)
How do you calculate the seller (writer) gain/loss on a put option?
(Long position)
The buyer’s gain (loss) necessarily mirrors the seller’s loss (gain). The amount of gain and loss on a put option can be calculated as follows:
= Units of underlying x (Option price - Excess of exercise price over market price)
What is the Put-call parity theorem?
The put-call parity theorem mathematically depicts the combinations of investment strategies that can be devised using European options (i.e. those with a single exercise date). The 2 sides of this equation represent combinations with identical outcomes (given identical exercise prices for the put and the call and identical expiration dates)
= Value of call + PV of exercise price (discounted at the risk-free rate) = Value of put + Value of underling
What does the left side of the Put-call parity theorem entail?
Left side of the put-call parity theorem formula:
= Value of call + PV of exercise price (discounted at the risk-free rate)
The buyer of a call may wish to hedge against the loss that they will incur if the market price of the underlying fails to rise sufficiently
The buyer can do this by investing the present value of the exercise price in a safe investment. If the option is out-of-the-money on the expiration date, the option holder has the return from this safe investment to make up for the loss
