Definition of Put-call parity relationship

Put-call parity relationship

The relationship between the price of a put and the price of a call on the same
underlying security with the same expiration date, which prevents arbitrage opportunities. Holding the stock
and buying a put will deliver the exact payoff as buying one call and investing the present value (PV) of the
exercise price. The call value equals C=S+P-PV(k).

Call

An option that gives the right to buy the underlying futures contract.

Call an option

To exercise a call option.

Call date

A date before maturity, specified at issuance, when the issuer of a bond may retire part of the bond
for a specified call price.

Call money rate

Also called the broker loan rate , the interest rate that banks charge brokers to finance
margin loans to investors. The broker charges the investor the call money rate plus a service charge.

Call option

An option contract that gives its holder the right (but not the obligation) to purchase a specified
number of shares of the underlying stock at the given strike price, on or before the expiration date of the
contract.
call premium
Premium in price above the par value of a bond or share of preferred stock that must be paid to
holders to redeem the bond or share of preferred stock before its scheduled maturity date.

Call price

The price, specified at issuance, at which the issuer of a bond may retire part of the bond at a
specified call date.

Call price

The price for which a bond can be repaid before maturity under a call provision.

Call protection

A feature of some callable bonds that establishes an initial period when the bonds may not be
called.

Call provision

An embedded option granting a bond issuer the right to buy back all or part of the issue prior
to maturity.

Call risk

The combination of cash flow uncertainty and reinvestment risk introduced by a call provision.

Call swaption

A swaption in which the buyer has the right to enter into a swap as a fixed-rate payer. The
writer therefore becomes the fixed-rate receiver/floating rate payer.

Callable

A financial security such as a bond with a call option attached to it, i.e., the issuer has the right to
call the security.

Conversion parity price

Covered call

A short call option position in which the writer owns the number of shares of the underlying
stock represented by the option contracts. Covered calls generally limit the risk the writer takes because the
stock does not have to be bought at the market price, if the holder of that option decides to exercise it.

Covered call writing strategy

A strategy that involves writing a call option on securities that the investor
owns in his or her portfolio. See covered or hedge option strategies.

Covered Put

A put option position in which the option writer also is short the corresponding stock or has
deposited, in a cash account, cash or cash equivalents equal to the exercise of the option. This limits the
option writer's risk because money or stock is already set aside. In the event that the holder of the put option
decides to exercise the option, the writer's risk is more limited than it would be on an uncovered or naked put
option.

Debt service parity approach

An analysis wherein the alternatives under consideration will provide the firm
with the exact same schedule of after-tax debt payments (including both interest and principal).

Effective call price

The strike price in an optional redemption provision plus the accrued interest to the
redemption date.

Interest rate parity theorem

Interest rate differential between two countries is equal to the difference
between the forward foreign exchange rate and the spot rate.

Irrational call option

The implied call imbedded in the MBS. Identified as irrational because the call is
sometimes not exercised when it is in the money (interest rates are below the threshold to refinance).
Sometimes exercised when not in the money (home sold without regard to the relative level of interest rates).

Margin call

A demand for additional funds because of adverse price movement. Maintenance margin
requirement, security deposit maintenance
Margin of safety With respect to working capital management, the difference between 1) the amount of longterm
financing, and 2) the sum of fixed assets and the permanent component of current assets.

Put bond

A bond that the holder may choose either to exchange for par value at some date or to extend for a
given number of years.

Put option

This security gives investors the right to sell (or put) fixed number of shares at a fixed price within
a given time frame. An investor, for example, might wish to have the right to sell shares of a stock at a certain
price by a certain time in order to protect, or hedge, an existing investment.

Put price

The price at which the asset will be sold if a put option is exercised. Also called the strike or
exercise price of a put option.

Put provision

payment date.

one country relative to the price level in another determines the rate of change of the exchange rate between
the two countries' currencies.

Spot futures parity theorem

Describes the theoretically correct relationship between spot and futures prices.
Violation of the parity relationship gives rise to arbitrage opportunities.

Throughput agreement

Transferable put right

An option issued by the firm to its shareholders to sell the firm one share of its
common stock at a fixed price (the strike price) within a stated period (the time to maturity). The put right is
"transferable" because it can be traded in the capital markets.

Uncovered call

A short call option position in which the writer does not own shares of underlying stock
represented by his option contracts. Also called a "naked" call, it is much riskier for the writer than a covered
call, where the writer owns the underlying stock. If the buyer of a call exercises the option to call, the writer
would be forced to buy the stock at market price.

Uncovered put

A short put option position in which the writer does not have a corresponding short stock
position or has not deposited, in a cash account, cash or cash equivalents equal to the exercise value of the
put. Also called "naked" puts, the writer has pledged to buy the stock at a certain price if the buyer of the
options chooses to exercise it. The nature of uncovered options means the writer's risk is unlimited.

Yield to call

The percentage rate of a bond or note, if you were to buy and hold the security until the call date.
This yield is valid only if the security is called prior to maturity. Generally bonds are callable over several
years and normally are called at a slight premium. The calculation of yield to call is based on the coupon rate,
length of time to the call and the market price.

Throughput contribution

Sales revenue less the cost of materials.

acid test ratio (also called the quick ratio)

The sum of cash, accounts receivable, and short-term marketable
investments (if any) is divided by
total current liabilities to compute this ratio. Suppose that the short-term
creditors were to pounce on a business and not agree to roll over the
debts owed to them by the business. In this rather extreme scenario, the
acid test ratio reveals whether its cash and near-cash assets are enough
to pay its short-term current liabilities. This ratio is an extreme test that
is not likely to be imposed on a business unless it is in financial straits.
This ratio is quite relevant when a business is in a liquidation situation
or bankruptcy proceedings.

net income (also called the bottom line, earnings, net earnings, and net

operating earnings)
This key figure equals sales revenue for a period
less all expenses for the period; also, any extraordinary gains and losses
for the period are included in this final profit figure. Everything is taken
into account to arrive at net income, which is popularly called the bottom
line. Net income is clearly the single most important number in business
financial reports.
