Stratified Composite Portfolio System for Non-Systematic Risk Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portfolio construction methods fail to effectively manage the complexity and heterogeneity of modern investment portfolios, lacking tools to systematically control for non-systematic risks and achieve predictable returns due to inadequate risk controls and classification systems.
Innovation Solution
A stratified or segmented composite portfolio system that uses functional attributes to segment investment securities into risk groups, allowing for targeted weighting and risk management by assigning specific weights to risk groups to achieve engineered risk objectives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If portfolio construction methods use traditional classification systems, then portfolio management becomes simpler, but the ability to systematically control non-systematic risks deteriorates
Solution Approach 1:
The patent segments investment securities into multiple strata based on functional attributes (e.g., industry, geography, business model). Each stratum represents a distinct risk category, allowing systematic control of non-systematic risks while maintaining manageable complexity through hierarchical organization.
Solution Approach 2:
The patent introduces functional attributes as new parameters for classification, moving beyond traditional classification systems. By tagging securities with multiple functional attributes and organizing them into strata based on these parameters, the system achieves both systematic risk control and operational efficiency.
2Reliability
If portfolio construction methods increase segmentation and stratification, then risk control effectiveness improves, but system complexity increases
Solution Approach 1:
The patent divides the portfolio into multiple strata based on functional attributes, creating a hierarchical structure that systematically controls risks. This segmentation improves risk control by isolating non-systematic risks within specific strata while maintaining overall portfolio coherence through the hierarchical framework.
Solution Approach 2:
The patent creates a universal stratification framework that can be applied across different portfolio types and asset classes. The functional attribute tagging system serves multiple purposes: risk classification, performance attribution, and portfolio construction, reducing complexity despite increased segmentation.
3Device complexity
If traditional portfolio methods are used, then system simplicity is maintained, but the ability to achieve predictable returns deteriorates
Solution Approach 1:
The patent introduces functional attributes as new parameters for organizing and analyzing investment securities. By tagging securities with attributes such as industry, geography, and business model, the system enables more predictable return estimation through stratified analysis while maintaining manageable complexity through systematic parameter organization.
Data Source
AI summary
A stratified or segmented composite data structure can be formed by selecting a group of data entities, stratifying or segmenting them according to attributes, and assigning relative weights to the components based on their stratified or segmented positions. The attributes are selected from a universe of possible values. Further positive and negative biases can be applied at any arbitrary point or position, including to individual data entities, groups of arbitrarily selected data entities, or arbitrary positions.
