Systems and methods for data normalization for use in scoring and balancing a portfolio

A method for evaluating market participants' stock portfolios and distributing actionable environmental, social and governance (ESG) stock data over a network to multiple remote market participant terminals, the method comprising:

• receiving from multiple sources non-standardized electronic ESG data for a plurality of stocks, wherein
• the ESG data include multiple source ESG parameters and
• the ESG data from each of two or more sources include at least one different ESG parameter;
• establishing user-selected ESG parameters, the user-selected ESG parameters being different than one or more of the source ESG parameters;
• associating the ESG data of the multiple sources with the user-selected ESG parameters by mapping the ESG parameters of each source to the user-selected parameters;
• receiving from users an indication of importance for one or more of the user-selected parameters;
• generating an ESG score for the stock portfolio of a user based on the ESG data of at least the two or more sources, the mapping of ESG source parameters to the user-selected parameters and the user indication of importance of the user-selected parameters;
• identifying, based on the ESG data of at least the two or more sources, the mapping of ESG parameters to the user-selected parameters, the user indication of importance of the user-selected parameters, and industry sector information, one or more alternative securities to an identified security in the user portfolio, to improve the ESG score for the portfolio.
