Course description

Correlation and Related Dependency Concepts in Investment Management

Despite the very well-known facts that dependencies in financial markets are time-variable and can have a major impact on the overall risk of portfolios and balance sheets, information regarding advanced methodologies in dependency analysis is hard to find and often fragmentary.

In this intensive program, correlation and related dependency concepts take centre stage. After a systematic introduction to empirical and mathematical properties of the traditional correlation concept, more recent methodologies are presented and examined in detail. This will help practitioners to derive deeper insights into real-word dependency structures, and solve practical issues in working with scenario-based approaches and deriving forward-looking estimators.

Participants will solve exercises based on typical situations encountered in applied dependency analysis, allowing them to find new inspiration and to take home practical tools to further improve their practice.

Learning Objectives

  • Understand the limitations of traditional linear correlation analysis
  • Gain familiarity with modern dependency concepts beyond correlation
  • Learn how to apply scenario analysis to correlation forecasting and stress-testing
  • Analyze the implications of dependency on portfolio risk
  • Gain a deeper understanding of the advantages, and disadvantages, of quantitative methods in investment decision making
