Proxy Basket for Actively Managed Fund Portfolio Confidentiality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Actively managed mutual funds face challenges in maintaining confidentiality of their portfolios, which can lead to free riding and front running if public disclosure of their securities is made, as investors can exploit the fund's management decisions for profit without paying fees or respecting the fund's policies.
Innovation Solution
Creating a proxy basket of financial assets, where weights are determined based solely on public information, ensuring its valuation is within a threshold percentage of the actively managed fund's value, allowing for a correlated but non-disclosed portfolio that can be used as a medium of exchange without revealing the fund's actual holdings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the actual portfolio of securities held by the actively managed fund is disclosed publicly, then transparency and investor information access are improved, but the fund becomes vulnerable to free riding and front running by investors who can exploit the portfolio information for profit
Solution Approach 1:
The patent creates a proxy portfolio that replicates the performance characteristics of the actual fund portfolio without disclosing the specific securities holdings. The proxy portfolio is constructed using publicly available information and statistical methods to match the fund's risk-return profile, sector exposure, and other key characteristics, thereby providing transparency benefits while maintaining confidentiality and preventing exploitation
Solution Approach 2:
The proxy portfolio acts as an intermediary between the actual fund portfolio and the public market. Instead of directly disclosing the actual portfolio contents, the fund publishes the proxy portfolio which serves as a substitute that captures the essential investment characteristics without revealing proprietary information that could be exploited by investors
2Reliability
If a proxy portfolio is created to maintain confidentiality, then portfolio security is improved, but the complexity of creating and maintaining the proxy increases
Solution Approach 1:
The patent transforms the portfolio representation from specific security holdings to aggregated statistical parameters such as sector weights, market cap distribution, and risk factors. By changing the representation parameters from individual securities to portfolio-level characteristics, the system maintains confidentiality while reducing the complexity of proxy construction and maintenance
3Measurement precision
If the proxy portfolio is updated frequently to reflect current holdings, then accuracy relative to the actual fund is improved, but the transaction costs and operational burden increase
Solution Approach 1:
The patent implements periodic updates of the proxy portfolio at predetermined intervals (e.g., quarterly or semi-annually) rather than continuous updates. This periodic approach maintains sufficient accuracy for regulatory and informational purposes while significantly reducing transaction costs, operational burden, and complexity compared to real-time or frequent updates

Among other things, receiving public information about an actively managed fund, selecting a group of financial assets, determining a group of weights corresponding to the group of financial assets thereby determining a weighted group of financial assets, the weights being determined based only on the public information, and publishing the contents of the weighted group of financial assets, wherein an expected valuation of the weighted group of financial assets is within a threshold percentage of an expected valuation of the actively managed fund.
