RT Journal Article SR Electronic T1 Correlation's Importance to the Long-Term Investor is Overrated JF The Journal of Investing FD Institutional Investor Journals SP 8 OP 14 DO 10.3905/joi.2003.319562 VO 12 IS 4 A1 Ernest M Ankrim YR 2003 UL https://pm-research.com/content/12/4/8.abstract AB Has the recent rise in the correlation between domestic and foreign equity returns been accompanied by a reduced difference between their returns? For many divisions of the broad equity asset class, the levels of pairwise correlations say very little about the return differences that investors experienced over recent history. When risk to an investor is the regret that derives from the possibility of holding only the poorer performing of domestic and foreign equity, there is little evidence that increases in correlation reduce the benefits of diversification.
