Overlap Analyzer
It's common to end up holding several mutual funds that all own the same underlying stocks — which means you're carrying more concentrated risk than your fund count suggests. The Overlap Analyzer checks for exactly that.
How it works
The analyzer compares the stock-level holdings across your mutual funds and highlights where they overlap significantly — for example, if three of your five funds all have a large position in the same handful of large-cap stocks.
High overlap isn't automatically bad, but it often means you're not getting the diversification you think you are by holding multiple funds. Worth a look especially before adding a new fund to your portfolio.
This works best once your full mutual fund portfolio is imported — see Get Your CAS / NSDL Statement.
