The different types of portfolio stress-testing

< 1 minute read

In previous articles published on DISCUS, Quintin Rayer gave a brief overview of portfolio stress-testing, what it can and cannot do, and offered a definition.  This third article in the series outlines the range of stress-testing methodologies available and offers a classification.

To recap, extreme market moves can negatively impact portfolios in ways that may not be captured by conventional risk measures and diversification breakdown may mean that portfolio values are not protected. With guidance, you may be able to use stress-testing to estimate the impact on your clients’ portfolios and arrange for appropriate restructuring to limit the downside.  This helps demonstrate that advisers and investment managers are working hard to protect portfolios and clients can be reassured that robust investment processes are in place.

This article is the third in a series making up a helpful introduction to IFAs less familiar with portfolio stress-testing.  The previous articles can be found here:
