(K-S(T))+
European Call Option payoff
(S(T)-K)+
Covered Put Option components

Short forward payoff
F-S(T)
Derivative securities can only be used for hedging, i.e., they can only be bought and written by agents who already have a position in the underlying asset
False
Writing derivative securities can be a regulatory requirement
False
The pre-paid forward price of a non-dividend-paying stock is strictly decreasing with respect to the delivery date
False- Pre-paid forward = S(0) delivery date has no effect on the price
The position consisting of ONE LONG SYNTHETIC FORWARD CONTRACT benefits from falling prices in the underlying asset
False- A synthetic forward contract has the payoff function which is increasing as a function of the final price of the underlying asset. So it benefits from rising prices and not from falling prices of the underlying asset
A producer of oranges wishes to hedge using put options on oranges. She should WRITE put options
False- Producers should buy put options
Put-call parity applies to both American and European options
False- Put-call parity applies to only European options
Suppose stock XYZ has a current price of 100. The forward price for delivery of this stock in 1 year is 110. Also, assume there are no dividends, and that the annual effective interest rate is 10%, unless otherwise indicated. Which of the following is false? D. If the 10% interest rate were continuously compounded instead of annual effective, then it would be more beneficial to invest in the stock, rather than the forward contract
False- The profit of the stock investor is always 100e^(1.1)-100>0 below the profit of the forward contract investor
A COVERED PUT consists of a written put and a short position in the underlying asset
False- covered put consists of written put option and buying the underlying
Users of forward contracts are more able to minimize credit risk than are users of futures contracts
False- forward contracts do not have margin accounts
In the setting of a futures contract, a margin call is issued if the balance in the margin account drops below the initial margin
False- if falls below the maintenance margin level
The agent is ONLY allowed to write options on an underlying asset if they already own units on the underlying
False- the so-called NAKED writing option is a legal and common practice
A covered call is a portfolio consisting of a written call option and the short underlying
False- write call buy underlying
Reinsurance companies can further share risk by investing in catastrophe bonds
False-- Reinsurance companies ISSUE catastrophe bonds

True
Derivative securities are sometimes used as employee compensation
True
Floors commonly arise when the producer of a commodity or the owner of a risky asset (shares of stock, etc.) uses PUTS to hedge their exposure to risk
True
Forward contracts are more customized to suit the buyers needs than futures contracts are
True
Forward contracts can be used to synthetically switch a portfolio invested in stocks into bonds

Frequent marking-to-market an settlement of future contracts can lead to pricing differences between a futures contract and an otherwise identical forward contract
True
Futures contracts are more liquid, as one can offset an obligation by taking the opposite position
True
Futures contracts are settled daily, and marked-to-market
True
Futures contracts are structured to minimize the effects of credit risk
True
Futures contracts have price limits, beyond which trading may be temporarily halted

True
If Kp=Kc then it is a zero-width collar
True
In an insurance market, individuals that do not want to incur losses have shared risk with individuals that do incur losses
True
In the case of a fully-leveraged portfolio, the payoff and the profit are always equal
True
Insurance companies can share risk by ceding some of the excess risk from large claims to reinsurers
True
Naked writing is the practice of writing options without taking an offsetting position in the underlying asset
True
On the expiration date of your American call option, you look back and you realize that you exercised the option at the optimal time. This means that the time of early exercise was when the price of the underlying asset achieved its maximum during the life of the option
True
Over-the-counter forward contracts can be customized to suit the buyer or seller, whereas futures contracts are standardized
True
Reinsurance companies endeavor to share risk by issuing catastrophe bonds
True
Risk sharing reduces diversifiable risk, more so than reducing non-diversifiable risk

True
Derivative securities can reduce the risk of both the buyer and writer of the security
True - Future contracts are an example of this situation
The European call option is LONG with respect to the underlying
True - the payoff and profit curves are both increasing functions
It is possible for the buyer and the write of the same option to end up having the same profit on the exercise date
True - this happens if they both break even , i.e., if both of their profits equals 0
Producers have an inherent LONG position in their product
True- Producers or manufacturers of goods and services (commodities) are going to be profitable if the revenue from the sale of produced goods in the market exceeds the manufacturing costs
The profit diagram and the payoff diagram for long positions in a forward contract are identical
True- Profit=Payoff
Suppose stock XYZ has a current price of 100. The forward price for delivery of this stock in 1 year is 110. Also, assume there are no dividends, and that the annual effective interest rate is 10%, unless otherwise indicated. Which of the following is false? C. There is no comparative advantage to investing in the stock versus investing in the forward contract
True- The profits are equal
Suppose stock XYZ has a current price of 100. The forward price for delivery of this stock in 1 year is 110. Also, assume there are no dividends, and that the annual effective interest rate is 10%, unless otherwise indicated. Which of the following is false? A. the time-1 profit diagram and the time-1 payoff diagram for long positions in this forward contract are identical
True- There is no initial cost to entering a forward contract, so its payoff and profit are always equal
Suppose stock XYZ has a current price of 100. The forward price for delivery of this stock in 1 year is 110. Also, assume there are no dividends, and that the annual effective interest rate is 10%, unless otherwise indicated. Which of the following is false? B. The time-1 profit for a long position in this forward contract is exactly opposite to the time-1 profit for the corresponding short forward position
True- This statement is ALWAYS true for long and shirt positions in the same contract
Suppose stock XYZ has a current price of 100. The forward price for delivery of this stock in 1 year is 110. Also, assume there are no dividends, and that the annual effective interest rate is 10%, unless otherwise indicated. Which of the following is false? E. If there was a dividend of 3.00 paid 6 months from now, then it would be more beneficial to invest in the stock, rather than the forward contract
True- Without any dividend payments, the two positions are equivalent. The dividend payment is given to the stock investor and not to the forward investor, so the stock investor is certainly better off
The users or buyers of commodities have an inherent short position with respect to that commodity
True- the users or buyers of commodities benefit from a decrease in the price of the good
