Have I picked up the right mutual funds to invest for 15 years?

I have been investing in four mutual fund schemes via SIP for the last one year.
Aditya Birla Sun Life Frontline Equity Fund: Rs 4,000
HDFC Top 100 Fund: Rs 3,000
Motilal Oswal Multicap 35 Fund: Rs 3,000
Mirae Asset Emerging Bluechip Fund: Rs 2,000

Am I going in the right direction? My investment horizon is around 15 years. Please guide me.

Equity is an excellent asset class for your 15-year investment horizon. I hope you stay disciplined and persevering during this long journey. The only change I would recommend is to include a mid and/or small cap in your portfolio since you have a longer investment horizon. As of now, you have 80% exposure in large cap.

You can consider investing in DSP Midcap Fund/ Nippon India Small Cap Fund/HDFC Small Cap Fund instead of Aditya Birla Sun Life Frontline Equity Fund. It will reduce your aggregate large cap allocation. Please remember, mid and small cap funds are more volatile than large cap funds and will demand your patience.
