I was reading on another site, if one has SIP between 5th to 10th of month, there is greater chance of good return than having SIPs on other dates (or specially later part of the month). I am not convinced. Isn’t it like investing on timing the market? If I go to SIP route, irrespective of date of the month (as long as I have the amount available for SIP), do I need to bother about SIP date?
