London Stock Exchange - MTS
1 In 2007, after Borsa Italiana announced its call option exercise right to acquire full control of MBE
Holdings, the combined Group would now control Mercato del Titoli di
Stato, or MTS. This merger of Borsa Italiana and MTS with the London Stock Exchange’s existing bond
listing business, enhanced the range of covered European fixed income
markets.https://store.theartofservice.com/the-call-option-toolkit.html

Valuation (finance) - Valuation overview
1 #Valuation of options|Option pricing models are used for certain types of financial assets
(e.g., Warrant (finance)|warrants, put options, call options, employee stock options, investments with embedded
options such as a callable bond) and are a complex present value model. The most common option pricing models are the Black–Scholes-Robert C. Merton|Merton
models and lattice model (finance)|lattice models.

Security (finance)
1 A 'security' or 'financial instrument' is a tradable asset of any kind.The United States Securities Exchange Act of 1934 defines a security as: Any note, stock,
treasury stock, Government investment|bond, debenture, certificate of interest or participation in any profit-sharing agreement or in any oil, gas, or
other mineral royalties|royalty or lease, any collateral (finance)|collateral Trust certificate (finance)|trust certificate, preorganization certificate or

interest or participation in, temporary or interim certificate for, receipt for, or warrant or right to subscribe to or purchase, any of the foregoing; but shall
not include currency or any note, draft, bill of exchange, or banker's acceptance which has a Maturity (finance)|maturity at the time of issuance of not exceeding nine months, exclusive of days of grace, or any renewal thereof

Electricity market - Risk management
1 Many other Hedge (finance)|hedging arrangements, such as swing

Corporate finance - Valuing flexibility
1 Again, a DCF valuation would capture only one of these outcomes.) Here: (1) using Option
(finance)|financial option theory as a framework, the decision to be taken is identified as
corresponding to either a call option or a put option; (2) an appropriate valuation technique is
then employed – usually a variant on the Binomial options model or a bespoke Monte Carlo methods in finance|simulation model,
while Black-Scholes formula|Black Scholes type formulae are used less often; see Contingent

Executive pay
1 It is typically a mixture of salary, bonuses, shares of or call options on the company stock, benefits,
and perquisites, ideally configured to take into account government regulations, tax law, the desires of the organization and the executive,
and rewards for performance.[http://books.google.com/books?

Commodity market - Call options
1 In a call option counterparty|counterparties enter into a financial
contract option where the buyer purchases the right but not the
obligation to buy an agreed quantity of a particular commodity or financial instrument (the underlying) from the seller of the option at a certain time
(the expiration date) for a certain price (the strike price)

Right of first refusal
1 'Right of first refusal' ('ROFR' or 'RFR') is a contractual right that gives
its holder the option to enter a business transaction with the owner of something, according to specified terms, before the owner is entitled to
enter into that transaction with a third party. In brief, the right of first refusal is similar in concept to a call
option.https://store.theartofservice.com/the-call-option-toolkit.html

Employee stock option
1 An 'employee stock option' ('ESO') is commonly viewed as a complex call option on the common
stock of a company, granted by the company to an employee as part of the employee's Remuneration|
remuneration package.[http://www.esopdirect.com/faq.html see
Employee Stock Option FAQ's] Regulators and economists have since specified that employee stock
options is a label that refers to compensation contracts between an employer and an employee
that carries some characteristics of financial options but are not in and of themselves options (that is they
are compensation contracts).

Employee stock option
1 From the employee's point of view, the compensation contract provides a conditional right to buy the equity of the employer and when modeled
as an option, the employee's perspective is that of a long position
in a call option

Employee stock option - Objectives
1 Employee stock options are similar to exchange traded call options issued
by a company with respect to its own stock.

![Page 22: Call Option .](https://reader035.fdocuments.us/reader035/viewer/2022062804/56649e9e5503460f94b9f9e7/html5/thumbnails/22.jpg)
Employee stock option - Contract differences
1 There is a substantial risk that when the ESOs are granted (perhaps
50%[http://www.hoadley.net/options/optiongraphs.aspx Call Option Price Time Value by Stock Price]) that the options
will be worthless at expiration.http://www.hoadley.net/option
s/probgraphs.aspx This should encourage the holders to reduce risk by
selling exchange traded call options

At the money
1 In finance, 'moneyness' is the relative position of the current price
(or future price) of an underlying asset (e.g., a stock) with respect to
the strike price of a derivative (finance)|derivative, most commonly
a call option or a put option

At the money
1 It can be measured in percentage probability of expiring in the money,
which is the forward value of a binary call option with the given strike,

At the money - Example
1 Suppose the current stock price of IBM is $100. A call option|call or put option with a strike of $100 is at-the-money. A call option with a strike of $80 is in-the-money (100 minus; 80
= 20 gt; 0). A put option with a strike at $80 is out-of-the-money (80 minus; 100 = minus;20 lt; 0).
Conversely, a call option with a $120 strike is out-of-the-money and a put option with a $120 strike is in-the-
money.

At the money - Intrinsic value and time value
1 The intrinsic value (or monetary value) of an option is its value
assuming it were exercised immediately. Thus if the current
(Spot price|spot) price of the underlying security (or commodity etc.) is above the agreed (Strike
price|strike) price, a Call option|call has positive intrinsic value (and is called in the money), while a Put
option|put has zero intrinsic value (and is out of the money).

At the money - In the money
1 An 'in the money' (ITM) option has positive intrinsic value as well as time value. A call option is in the
money when the strike price is below the spot price. A put option is in the
money when the strike price is above the spot price.

At the money - Out of the money
1 An 'out of the money' (OTM) option has no intrinsic value. A call option is
out of the money when the strike price is above the spot price of the underlying security. A put option is out of the money when the strike
price is below the spot price.

At the money - Simple examples
1 Thus a 25 Delta call option has less than 25% moneyness, usually
slightly less, and a 50 Delta ATM cal option has less than 50%
moneyness; these discrepancies can be observed in prices of binary
options and vertical spreads

Derivative (finance) - Common derivative contract types
1 The buyer of a Call option has a right to buy a certain quantity of the
underlying asset, at a specified price on or before a given date in the
future, he however has no obligation whatsoever to carry out this right

Put option
1 Puts may also be combined with other derivatives as part of more
complex investment strategies, and in particular, may be useful for
Hedge (finance)|hedging. Note that by put-call parity, a European put
can be replaced by buying the appropriate call option and selling an
appropriate forward contract.

Rational pricing - Options
1 It is possible to create a position consisting of 'Δ' shares and 1 call
option|call sold, such that the position’s value will be identical in the S up and S down states, and hence known with certainty (see
Delta hedging)

Long-Term Capital Management - 1998 bailout
1 LTCM's strategies were compared (a contrast with the market efficiency
aphorism that there are no $100 bills lying on the street, as someone else
has already picked them up) to picking up nickels in front of a bulldozer – a likely small gain
balanced against a small chance of a large loss, like the payouts from
selling an out-of-the-money naked call option.

Valuation of options - Intrinsic value
1 For a call option, the option is in-the-money if the underlying price is
higher than the strike price; then the intrinsic value is the underlying price
minus the strike price

Valuation of options - Time value
1 * Price of the underlying: Any fluctuation in the price of the
underlying (stock/index/commodity) obviously has the largest impact on premium of an option contract. An
increase in the underlying price increases the premium of call option and decreases the premium of put
option. Reverse is true when underlying price decreases.

Agency Theory - Options framework
1 At the same time, since equity may be seen as a call option on the value
of the firm, an increase in the variance in the firm value, other
things remaining equal, will lead to an increase in the value of equity,
and stockholders may therefore take risky projects with negative net
present values, which while making them better off, may make the
bondholders worse offhttps://store.theartofservice.com/the-call-option-toolkit.html

Call option
1 The buyer of the call option has the right, but not the obligation to buy an
agreed quantity of a particular commodity or financial instrument (the underlying) from the seller of the option at a certain time (the

Call option

you have sold a call option).

Call option
1 The initial transaction in this context (buying/selling a call option) is not
the supplying of a physical or financial asset (the underlying
instrument). Rather it is the granting of the right to buy the underlying asset, in exchange for a fee— the
option price or premium.

Convertible bond - Types
1 *'Reverse convertibles' are a less common variation, mostly issued synthetically. They would be opposite of the vanilla structure:

redeem at par its bond. This negative convexity would be compensated by a usually high regular coupon payment.

1 'Put/call ratio' (or put–call ratio, PCR) is a technical indicator demonstrating investors'
sentiment.[http://www.investopedia.com/terms/p/putcallratio.asp Put–Call Ratio] The ratio represents a proportion between all the put options and all the call options purchased on
any given day. The put/call ratio can be calculated for any individual stock, as well as
for any index, or can be aggregated. The ratio may be calculated using the numbers of puts and calls or on a dollar-weighted basis.

that are expected to decrease in value. This is different from the risk reversal strategies
where investors will simultaneously buy a call option and sell a put option to simulate being
long in a stock.

Bond option
1 Generally, one buys a call option on the bond if one believes that interest rates will fall,
causing an increase in bond prices. Likewise, one buys the put option if one believes that
the opposite will be the case. [http://financial-dictionary.thefreedictionary.com/Bond
%2boption] One result of trading in a bond option, is that the price of the underlying
bond is locked in for the term of the contract, thereby reducing the credit risk associated
with fluctuations in the bond price.

Bond option - Embedded options
1 *Callable bond: allows the issuer to buy back the bond at a

Put-call parity
1 In financial mathematics, 'put–call parity' defines a relationship
between the price of a European call option and European put option, both
with the identical strike price and expiry, namely that a portfolio of long a call option and short a put option is equivalent to (and hence
has the same value as) a single forward contract at this strike price

Put-call parity - Derivation
1 Consider a call option and a put option with the same strike K for

assume the existence of a Bond (finance)|bond that pays 1 dollar at
maturity time T. The bond price may be random (like the stock) but must
equal 1 at maturity.

Put-call parity - Derivation
1 Let the price of S be S(t) at time t. Now assemble a portfolio by buying a call option
C and selling a put option P of the same maturity T and strike K. The payoff for this portfolio is S(T) - K. Now assemble a second portfolio by buying one share and borrowing
K bonds. Note the payoff of the latter portfolio is also S(T) - K at time T, since our share bought for S(t) will be worth S(T) and
the borrowed bonds will be worth K.

1 That is, if portfolio Z_2 always has better values than portfolio Z_1 under almost surely|almost all
scenarios then the risk of Z_2 should be less than the risk of Z_1. E.g. If
Z_1 is an in the money call option (or otherwise) on a stock, and Z_2 is also
an in the money call option with a lower strike price.

Exercise (options)
1 When exercising a call option, the owner of the option purchases the underlying shares (or commodities, fixed interest securities, etc.) at the strike price from the option seller,
while for a put option, the owner of the option sells the underlying to the
option seller, again at the strike price.

Exercise (options) - Exercise Considerations
1 # For an American-style call option, 'early exercise' is a possibility whenever the
benefits of being long the underlier outweigh the cost of surrendering the option early. For instance, on the day before an ex-dividend
date, it may make sense to exercise an equity call option early in order to collect the
dividend. In general, equity call options should only be exercised early on the day
before an ex-dividend date, and then only for deep Moneyness|in-the-money options.

Exercise (options) - Early Exercise Strategy
1 A common strategy among professional option traders is to sell large quantities of in-the-
money calls just prior to an ex-dividend date. Quite often, non-professional option traders
may not understand the benefit of exercising a call option early, and therefore may
unintentionally forgo the value of the dividend. The professional trader may only be 'assigned' on a portion of the calls, and therefore profits by receiving a dividend on the stock used to
hedge the calls that are not exercised.

Extendible bond
1 'Extendible bond' (or extendable bond[http://www.investorwords.com/7282/exten
dable_bond.html extendable bond]) is a complex bond with the embedded option for a holder to extend its maturity date by a number
of years.[http://lexicon.ft.com/term.asp?t=extendable-bond Financial Times Lexicon]
[http://classes.uleth.ca/200803/mgt3412a/ch02.ppt Investment Alternatives] Such a bond may
be considered as a portfolio of a straight, shorter-term bond and a call option to buy a
longer-term bond

Notional amount - Equity options
1 So, for instance, if you purchase a 100 share equity call option with a strike of $60 for a stock that is currently trading at $60, then
you have the same upside potential as someone who holds $6,000 of stock (1
option * 100 multiplier * $60), but you may have paid only $5/share (for a total of $500),
so by this measure you have achieved Leverage (finance)|leverage of $6,000/$500 = 12x.A different measure of leverage would
be your Delta (finance)|Delta

Notional amount - Foreign Currency/Exchange or FX derivatives
1 Suppose you have a call option on USD/JPY struck at 110, and you buy
one of these. Then this gives you the option to pay 100 USD and receive 110 x 100 = 11,000 JPY, so the USD
notional is 100 USD, and the JPY notional is 11,000 JPY.

Puttable bond
1 The price behaviour of puttable bonds is the opposite of that of a
callable bond. Since call option and put option are not mutually
exclusive, a bond may have both options

Dynamic Hedging - Insurance
1 For example, bonds and equities can be used to replicate a call option. The call option can then be easily valued
as the value of the bond/equity portfolio, hence not requiring one to
value the call option directly.

Intrinsic theory of value
1 # For call options, this is the difference between the underlying
stock's price and the strike price. For put options, it is the difference
between the strike price and the underlying stock's price. In the case
of both puts and calls, if the respective difference value is
negative, the instrinsic value is given as zero.
