Good morning Zahid, thank you for your question. The best tool to use in my opinion is a morning star X-ray Tool. It will brake the positions by holdings, sectors and will give you all the information you need. It should be more then sufficient to help you . here is the link http://portfolio.morningstar.com/Rtport/Free/InstantXRayDEntry.aspx Best of luck Sincerely Michael Mezheritskiy. www.VisionaryWealthMgmt.com
Great question and I will agree with Michael. Morningstar has what will give you the best answer. Your question also speaks to the importance of understanding your true diversity in a portfolio. An investor could own 100 funds or ETF's and still not be broadly diversified. Its only when attention is paid to the underling assets that risk can be spread out effectively.
This is a good question and an issue you should be concerned about. Unfortunately I am unaware of any free tool that makes this exercise easy. I did find this US News Money Personal Finance web article entitled “How to “Dedupe” your Mutual Funds” at http://money.usnews.com/money/blogs/the-smarter-mutual-fund-investor/2013/01/18/how-to-dedupe--your-mutual-funds
I have the ability to run an overlap report between funds in house with my very expensive software. But otherwise to do this at home you will have to follow the instructions in the article or get a list of the holdings for each fund into a spreadsheet and sort by name to identify which positions are held by both funds.
All great answers... Aside from Morningstar, some of the discount brokerages and mutual fund companies offer comparative tools as well. T Rowe Price used to have such a tool... you didn't need to have an account there, but needed to register to the site to use it. www.troweprice.com Best Regards, Rod
