What is Correlation?

Correlation measures the historical relationship between two assets. A value of 1.00 (100%) means they move perfectly in sync. For tax loss harvesting, high correlation is generally desired to stay in the market while realizing a loss.

Index Methodology

Under the wash sale rule, "substantially identical" assets are disallowed for loss claims. Many investors argue that ETFs tracking different indices (e.g., S&P 500 vs. Russell 1000) are not substantially identical.
