Since last 3 years i am in Canada. I have one son.I am 35 years old. I made some good savings in Canada. Now, i am coming back to india. I am thinking to invest my money in SIP for my retirement and also for my son’s education and his marriage. I read about Bajaj Capital and its SIP plans. Can you suggest me should i have to go with it or not? If there is another good scheme or plan for my purpose; please send me your reply.
I preffered to invest in government sector . or you can suggest any good mutual fund .
