It is better to invest in Tax-free bonds of NHAI, Hudco, PFC and IRFC rather than investing in ELSS. Anyway, ELSS will do away with its tax saving title post DTC implementation effective April 1, 2012. If you see performance of ELSS over the last one year period, it has generated by just over 1.7% as compared to returns delivered by tax free bonds of 8.5-9.5%. So while the ELSS still remains as a hazy proposition, it is better to invest in safe and secured asset class.
Mutual funds give higher return but with a risk( its important to choose a good fund) while PPF is safe and its income are tax free.The investment has tax rebate too which Mutual fund will loose when DTC is implemented.
I would still diversify as an investor I believe one should invest in all asset class and the diversification as per one`s age-the younger you are- its towards equity, as you grow older towards property,gold,fixed income.
Anytime ELSS is better than PPF. It gives you tax benefit along with good returns. The only key is to invest in a good ELSS scheme which requires little effort to choose the good scheme. CRISIL has rated three schemes which is good to look at if anyone wants to invest in ELSS http://t.in.com/bjpg
