Build a correlation matrix across tickers to see which holdings move together and which offset each other.
Add tickers with the search box; the matrix starts with a broad default set spanning equities, bonds, gold, oil, and the dollar. Remove any chip you do not need to keep the matrix focused.
Cells are color-coded from strongly positive to strongly negative correlation. Strong positive values mean two assets tend to move together; strong negative values mean they tend to offset. The insights panel calls out the most notable relationships.
Use the matrix to check whether holdings you think are diversified are actually driven by the same factor. If everything is strongly correlated, you may have one concentrated bet wearing several tickers.
