A 15-year experiment comparing daily, monthly, and quarterly Systematic Investment Plans (SIPs) in the Nifty 50 index revealed negligible differences in final returns. Despite varying investment frequencies, all SIPs, with the same total invested amount, yielded approximately Rs 1.15 crore with XIRR around 13.80-13.83 percent. The study suggests that long-term investing consistency, rather than frequency, is the primary driver of returns, with differences between SIP intervals being insignificant in real-world terms.
