TemporalConcepts
QName: NONE:
This is the core ontology for temporally sensitive terms and provides the basic definitions that are extended in other ontologies specific to securities, types of security and so on. These concepts include basic prices, yields, volatilities, spreads and so on, as well as times percentages and amounts.
Note that this is a highly conceptual foundational ontology of these concepts, as it distinguishes between for example the notions of price and the ways these are specified. These concepts should be reviewed to make reference to the newer Values ontology and may be further simplified for application ontologies.
current monetary amount
QName: NONE:CurrentMonetaryAmount
Monetary amount at the present time.
curve convexity
QName: NONE:CurveConvexity
The convexity of the curve between any two time-variant parameters.
dated duration specification
QName: NONE:DatedDurationSpecification
dated monetary amount
QName: NONE:DatedMonetaryAmount
dated past value
QName: NONE:DatedPastValue
A value at a given time and date. The value of a dated parameter, at a stated point in the past, present or future.
dated percentage
QName: NONE:DatedPercentage
debt margin spread
QName: NONE:DebtMarginSpread
The spread between a Bid Price and an Offer Price.
This is the spread between the two prices, in whichever way those are specified. So for example a margin spread may be the margin between two prices each specified as a yield spread or in percentage terms.
end of day price
QName: NONE:EndOfDayPrice
intra day price
QName: NONE:IntraDayPrice
price barter specification
QName: NONE:PriceBarterSpecification
The specification of the price of some item in terms of the number of some other (non currency) items of value that may exchanged for some quantity of the item so prices.
Note that in this case it is not necessarily the case that the item so priced is priced against one unit of that item; rather, the barter specification would most generally be a specification of the exchange of a number of the priced items for a number of the other item.
price exchange specification
QName: NONE:PriceExchangeSpecification
The specification of a price in terms of the exchange of some quantity of some item of value in return for some quantity of the item so priced. That is, a simple price or exchange ratio which specifies the amount of an asset that will be exchanged for another asset;
Prices that fall into this category include: 1. Exchange Rates the amount of one currency that can be exchanged for a unit of another currency 2. Commodity Price the amount of a specific Commodity that can be exchanged for a unit of a currency 3. Security price per Hundred where - albeit not explicit - the numerator asset is today’s Currency and the denominator Asset is future Currency (face Value). Notes Origin: NAB

price interpolation specification
QName: NONE:PriceInterpolationSpecification
A price which is an interpolation between two publicly available prices fo rths instrument.
Establish at review whether these are always interpolations between two prices of the instrument itself, or for example an interpolation between a price of the instrument and the price of something comparable. If the latter exists, then there are two kinds of interpolation specifications for price. The term currently modeled is the interpolation between two prices of the instrument so priced.
price model specification
QName: NONE:PriceModelSpecification
The specification of a price using a model.
price parameter specification
QName: NONE:PriceParameterSpecification
The specification of a price as a quote of the primary parameter passed into an algorithm used to calculate the Present Value of the relevant Asset.
Two significant examples of this pricing method are 1. Yields a yield is expressed as the annualized interest Rate that an investor requires for an investment. In the case of a loan the terms are set up so that the interest rate (coupon) equals that required yield and therefore the present value is equal to the loan principal. For a security, however the coupon rate is already determined so the required yield is applied to the projected cash flows in order to calculate a present value ( the price an investor is prepared to pay for the specified cash flows) Typically the required yield for a debt security is the yield to maturity 2. Volatilities in reality a volatility (used to calculate the fair value of an option) is a measure of the variability of the price of the transaction over which the beneficiary of the option has control. This is the primary parameter passed into an option valuation (eg Black-Scholes, Binomial) Notes Origin: NAB
price rate spread specification
QName: NONE:PriceRateSpreadSpecification
The specification of a price in terms of the difference between that price as a percentage, and some publicly available rate at that same point in time, such as the interest rate on a Treasury Note or an inter-bank rate (IBOR).
This is the different between two rates.
price ratio specification
QName: NONE:PriceRatioSpecification
The specification of a price in terms of some ratio to the face value of the item, expressed as a percentage. Security price per Hundred.
This is the default in debt pricing: debt instruments are commonly priced in percentage terms, the price being the percentage of the face value of the security. Debt prices that are specified and distributed in other ways, can be calculated back to this specification. Effectively the numerator asset is today’s Currency and the denominator Asset is future Currency (face Value).
price spread specification
QName: NONE:PriceSpreadSpecification
The specification of a price in terms of the difference between that price and some other paramater at that same point in time.
This is a class of price specifications which are specifications by way of spread, including spread between two yields, spread between two prices. The latter is relevant in Fx and Commodities for example.
price value
QName: NONE:PriceValue
Value given to a price. FIBIM
price volatility specification
QName: NONE:PriceVolatilitySpecification
The specification of an option price in terms of its volatility, that being a measure of the variability of the price of the transaction over which the beneficiary of the option has control.
In reality a volatility (used to calculate the fair value of an option) is a measure of the variability of the price of the transaction over which the beneficiary of the option has control. This is the primary parameter passed into an option valuation (eg Black-Scholes, Binomial) Notes origin:NAB
price yield spread specification
QName: NONE:PriceYieldSpreadSpecification
The specification of a price in terms of the difference between the yield that an investor requires for an investment and the published yield on some reference instrument at that same point in time, such as a Treasury Note.
In Debt pricing, Spreads are used because it's easier to quote things in a stable way, and it reflects the relative value of the thing. This is a spread of yields between the instrument so priced and the reference instrument. This spread is the mechanism by which the price is determined in yield terms, as the annualised interest rate that a investor requires for an investment. A yield is expressed as the annualised interest Rate that a investor requires for an investment. In the case of a loan the terms are set up so that the interest rate (coupon) equals that required yield and therefore the present value is equal to the loan principal. For a security, however the coupon rate is already determined so the required yield is applied to the projected cash flows in order to calculate a present value ( the price an investor is prepared to pay for the specified cash flows) Typically the required yield for a debt security is the yield to maturity. Note that this may be a discount or premium. Using the Spread lets you calculat e a yield from another observed yield as follows: Yield 1 = risk free yield Spread is to Yield 2 which is the instrument you are pricing. Earlier notes from Strucured finance review of prices quoted in relative terms: The price quoted in reference to an index e.g. LIBOR+50bp i.e. the yield. (the rate which is currently LIBOR)+50 is the price, and 50bp is the spread. e.g. Price:101% Yield = Benchmark + spread Price of 101% can be expressed as LIBOR+50 or Treasury+20 so these are separate ways of expressing the same thing. The one thing which is the price is expressed in these different ways. note also that unlike equities there's not a range of different price results from this. Spread = analytic. Bond has Price + yield. then compared to today's 90 day treasury value it's Spread is X, compared with (1 month) LIBOR its spread is Y and so on. Notes origin:NAB and SMER
pricing model
QName: NONE:PricingModel
The model used in the Price Model Specification.
It is beyond the capacity of the Semantic Model to model the method itself in detail. Key facts about this method may be modeled.
status code value
QName: NONE:StatusCodeValue
The value of the status of something that is set in terms of a list of selectable values taken from a list, which may take different values from that list at different times.
timed duration specification
QName: NONE:TimedDurationSpecification
A period of time, determined at some point in time.
timed monetary amount
QName: NONE:TimedMonetaryAmount
timed percentage
QName: NONE:TimedPercentage
unit price monetary specification
QName: NONE:UnitPriceMonetarySpecification
The specification of a price in terms of some monetary amount, that is a number and a currency unit, in exchange for one unit if the item so priced.
This is the most common kind of price specification, and specifies that a given thing costs a given number of Dollars or other currency units for one of the item or for some other well defined denimination of the unit (e.g. price per hundred). This is also the Fx rate for one unit of a given currency, being effectively the "price" of that currency in the specified currency.
