I just found this cool tool. Morningstar X-Ray lets you input your stocks and mutual funds and the amount held, and it then calculates the portfolio allocations between all major asset classes and by industry types, etc. I just spent a lot of time doing this using an excel spreadsheet, and I wish I would have known of this resource earlier. It might come in handy if you own actively managed mutual funds and want to see how balanced or diversified the holdings of all your mutual funds are.
