A while back my ex-colleague thanked me for my insistence as because of it he had amassed a large amount through his Systematic Investment Plans (SIPs), which in normal course would not have been possible. I was very happy as he continued his SIPs, irrespective of market conditions for the last 10 years. That was his secret to building a good portfolio via SIPs and needless to say he is getting a good return today when most of the investors are stopping their SIPs in despair.
