Abstract

Serious asset management depends on financial portfolios being valued accurately in a timely and complete manner. Custom, and in some jurisdiction, rules and regulations demand that they be “marked to market”, i.e. that their valuation as closely as possible reflect the market value of the financial instruments that make up a portfolio. A structured database of financial instruments and system and method for updating the prices of these instruments (the DPSM or Deductive Pricing System and Method) permits the use of information contained in the structure of financial instruments to complement the available market information and to deduce prices for virtually all instruments in a portfolio, even if they are only rarely traded and market prices are not available at most times.

Claims

1. A method of calculating the fair value of a portfolio of financial instruments including zero class instruments, simple instruments, aggregate instruments, derived instruments and composite instruments comprising the steps of:

a. automatically updating said financial instruments with market data whenever new financial data becomes available;

b. calculating the fair values for all derived financial instruments;

c. using said fair values as proxies for market prices for all financial instruments for which current market value is unavailable; and

d. calculating risk parameters for derived and composite instruments,

wherein said values derived in steps a-d above are used to calculate the value of said portfolio.

2. The method of claim 1 of calculating the fair value of a portfolio of financial instruments including zero class instruments, simple instruments, aggregate instruments, derived instruments and composite instruments comprising the additional steps of:

e. recording the price of a derived financial instrument;

f. recording the price of the underlying financial instrument if the last trade is within a fix period of time of the related derived financial instrument trade;

g. calculating the implied volatility of the value of the derived financial instrument; and

,

h. using the implied volatility to calculate the fair value of the derived financial instrument until the next observed trade in said derived financial instrument,

wherein the fair market value of said derived financial instrument may be calculated relatively accurately between trades of said derived financial instrument.

3. The method of claim 2 wherein said derived financial instrument comprises an option.

4. The method of claim 1 of calculating the fair value of a portfolio of financial instruments including zero class instruments, simple instruments, aggregate instruments, derived instruments and composite instruments comprising the steps of:

i. recording the price of a derived financial instrument;

j. determining the yield of said derived financial instrument from common market data;

k. determining the zero risk value of related government securities from current market data;

l. determining the rating of said derived financial instruments from rating services;

m. determining the derived financial instrument spread specific to said derived financial instrument; and

,

n. using said specific derived financial instrument spread to calculate the fair value of said derived financial instrument between trades in said derived financial instrument,

wherein the fair market value of said derived financial instrument may be calculated relatively accurately between trades of said derived financial instrument.

5. The method of claim 4 wherein said derived financial instrument comprises a bond.
