Can you please let me know if my fund selection is fine for investing over next 15 years

Your idea of investing in PPF and mutual funds over 15 years is a wise decision. The funds selected by you are all good performing and spread over large cap, diversified, midcap and balanced funds.

The category of funds chosen by you along with investment in PPF will balance out the risk over long term and can potentially give you very good returns. However, we would not suggest you to go with sectoral funds as this will unnecessarily add more risk to the entire selection of funds. By investing in two mid and small cap funds, you are already investing in high risk category of funds.

Also remember, that in the long term your objective should be to reach your financial goals and if the same can be achieved without investing in high risk funds then why not?

By the way – Have you planned your investments for 15 years with keeping some goals in mind? If not, then write your future financial goals and align the above investments with each of these goals.

One last suggestion – While it is a good idea to think about long term investing, one should must review the portfolio at least once every year and ensure if they are aligned with your goals.
