How Correlation works
A high positive value means they often moved in the same direction, zero suggests little linear relationship and a negative value means they tended to move oppositely. Correlation can change during stress and does not prove causation.
The figure should always be read with its measurement period, product type and source. A precise-looking number can still answer the wrong question when two unlike products or time periods are compared.
An example
If two funds hold similar companies, their returns may show correlation near one, so owning both may add less diversification than their names suggest.
Why it matters for your family
Use correlation with holdings and economic drivers when combining assets. Historical independence can disappear precisely when a family needs protection most.
Connect the figure to a dated goal before acting. Money for an emergency or near-term payment has different constraints from retirement money, even when the product description quotes the same statistic.
