As we all know, an index fund is a type of mutual fund or exchange-traded fund (ETF) with a portfolio constructed to match or track the components of a financial market index, such as the Nifty 50 Index.
Tracking difference is the discrepancy between Index Fund/ ETF performance and index performance.
Below is the ETFs and Index funds with high tracking error.
The above tracking error is since inception. ETFs and Index funds are considered to be low cost, but in here in India, the tracking difference are quite high and add to that expense ratio, the total works out to over 1-3% and higher in certain cases. These ETFs and Index funds are no longer low-cost as one would expect them to be.
