Where should I invest my additional Rs 10,000?

I am 29 years old. I am investing via monthly SIPs. My investment horizon is 15 years. I am an aggressive investor. I am currently investing in the following schemes:
ICICI Prudential Value Discovery Fund: Rs 2,000
HDFC Mid-Cap Opportunities Fund: Rs 1,500
Aditya Birla Sun Life Frontline Equity Fund: Rs 1,500
Axis ELSS Fund (Axis Long Term Equity Fund): Rs 5,000
L&T Emerging Business Fund: Rs 1,500
Reliance Small Cap Fund: Rs 1,500
I am planning to invest Rs 10,000 additionally. Should I continue with the existing funds? Where should I park the additional Rs 10,000 ?

Neeraj Chauhan, CEO, The Financial Mall, responds:

You are investing in good schemes. I would ask you to continue investing in these schemes. You haven't mentioned your investment horizon for the additional money. If it is the same as the horizon of your existing schemes, park your additional amount in your existing schemes by increasing your allocation to them. You already have six funds in your portfolio and there is no need to increase it further. Many schemes in your portfolio will make it over-diversified and impact your returns.
