Look through the wrapper
The number of funds you own does not directly tell you the number or weight of underlying exposures. Combine the fund allocation with each holding’s weight to see how much of your overall capital depends on the same security.
Inspect individual and sector exposure
Review the largest combined positions, then the sector breakdown. A sector label can differ between data vendors; this tool explicitly identifies a classification conflict instead of silently trusting one label. Broad sector totals still do not capture every economic correlation.
Do not count missing holdings as diversification
If a file covers only 60% of a fund, the other 40% could contain shared or distinct holdings. The analyzer keeps it unreported. Treat a reported top-ten concentration as based on the supplied data until full holdings are available.
Rebalance deliberately
A high overlap is not automatically bad. You may intentionally tilt a broad portfolio toward a style or sector. The tool makes that tilt visible; it does not decide an appropriate asset allocation or tax-efficient trade for you.
