The future of investment in share market or Mutual Funds depends on the economic development and industrial growth in the country. As on today we are in a developing regime. If the Govt policies are fruitful and we increase our share in the world trade, definitely these investments will yield good results. On the contrary, in adverse situation the gains will be very mediocre.
Anyway, investment in mutual funds is a long time measure to build a fortune and one has to select equity oriented as well as mixed schemes (equity + fixed income or debt) to make a balance portfolio. Your funds are more and less to that tune only. As you are going for SIP you have added advantage of average purchase value also.
Please make a note that today if you invest in Post Office schemes then also your corpus will be doubling in 10-12 years. Only thing is you may have to shell out a higher income tax as compared to your tax payout on long term equity capital gains. Still, you can consider a part of your investment in Post Office or other Govt schemes which are very safe.
Regarding switching of investments from one scheme to other and adjustment of your portfolio requires the help of an experienced financial adviser who can look upon your investments from that angle and advise the remedial measures if so required.
Knowledge is power.
