With Best Regards,
SRIKANTH SHANKAR MATRUBAI advised :
Even though you have age on your side, so I would advise you to go for Diversified Equity Funds, simply because Sector/Theme Funds tend to be volatile and you being a student, you may require money at a very short notice.
I advise you to Stop your 1000 RD in Post Office immediately, as these tend to give very low returns even eroding your investment value when you consider Inflation too. Unless this amount is for an Emergency, you should stop this RD immediately and switch the investment into Mutual Funds.
I suggest you to consider investing 1500 in 4 Funds as follows:
500 * 1 in DWS Tax Saving Fund (500) (You can avail Added Bonus of Free Life Insurance of 5 times your Investment)
500 * 1 in Fidelity Equity Fund (500)
250 * 2 in Reliance Growth Fund (500)
250 * 2 in Sundaram Select Focus Fund (500)
These Funds are low on Risk and Above Average on Returns and Should Serve you all.
Best of luck,
Srikanth Shankar Matrubai.
