Systems and methods related to bond valuation

A computer system comprising:

• one or more computer servers communicatively coupled to one or more external data sources,
• said computer servers comprising at least one processor, a non-transitory computer-readable medium storing computer-readable instructions, a receiving component, a filtering component, and a pricing valuation model, the computer-readable instructions, when executed by the at least one processor, causing the computer system to:
• execute a first portion of the pricing valuation model to determine a baseline pricing estimation, said first portion comprising a transaction cost adjustment component, a market adjustment component and value estimation component, and further causing the computer system to:
• receive, via the receiving component, valuation data for a security from the one or more external data sources,
• filter, via the filtering component, the received valuation data by removing outlier values according to a predetermined set of parameters,
• identify, via the transaction cost adjustment component, one or more characteristics of the security in the filtered valuation data,
• perform, via the transaction cost adjustment component, a first transaction cost adjustment regression calculation for the security based on a first set of characteristics from among the identified one or more characteristics in the filtered valuation data,
• determine, via the transaction cost adjustment component, a transaction cost adjustment coefficient for the security based on the first transaction cost adjustment regression calculation,
• determine, via the transaction cost adjustment component, a final transaction cost adjustment value for the security based on the transaction cost adjustment coefficient,
• perform, via the market adjustment component, a first market adjustment regression calculation based on a second set of characteristics of the security from among the identified one or more characteristics of the filtered valuation data, said first market adjustment regression calculation independent of said transaction cost adjustment regression calculation,
• determine, via the market adjustment component, a market adjustment coefficient for the security based on the first market adjustment regression calculation,
• determine, via the market adjustment component, a final market adjustment value for the security based on the market adjustment coefficient, and
• determine, by the value estimation component, the baseline pricing estimation of the security based on the final transaction cost adjustment value of the security and the final market adjustment value of the security, and
• store said baseline pricing estimation;
• and
• execute a second portion of the pricing valuation model to determine a current pricing estimation, in real-time or near real-time, said second portion further causing the computer system to:
• monitor live market data from among the one or more external data sources,
• retrieve the stored baseline pricing estimation,
• determine the current pricing estimation, in real-time or near real-time, in response to changes detected in the monitored live market data, said current pricing estimation based on the retrieved baseline pricing estimation and on at least a portion of the monitored live market data, and
• transmit the current pricing estimation to at least one computer.
