I have a SIP in Large cap (ICICI pru bluchip). Now, need to pick a small/mid cap for one more sip. I have short listed 1) Birla Sun Life MNC & 2) SBI Emerging Business Funds based upon last 5 y performance. Birla Sunlife seem to be giving better returns in last couple of years. Please help me to select a right fund among these for long term investment.
