Titel: | A new online-test for changes in correlations between assets |
Sprache (ISO): | en |
Zusammenfassung: | We apply a new test to determine whether correlations between assets are constant over time. The test statistic is a suitably standardized maximum of cumulative empirical correlation coefficients. An empirical application to various assets suggests that the test performs well in applications. We also propose a portfolio strategy based on our test which hedges against potential financial crises and show that it works in practice. JEL Classification: C12, C14, G01, G11 |
