Best SIP day: the 25th.

Best SIP day for this fund

The 25th

Thin edge

The 25th had the highest full-history XIRR for this fund. But 53 months of history is too little to tell whether the date matters at all.

Why the 25th

  1. Highest return of all 28 dates
    7.204%

    Full-history XIRR, 0.22 pp above the middle of the month (6.986%).

  2. How far apart the 28 dates are
    0.35 pp

    From the 18th (6.853%) up to the 25th. Wider than the 0.25 pp a date effect needs, but the order of dates didn't hold (-0.64, needs 0.6).

  3. What the spread is worth
    ₹4,536

    Between the highest- and lowest-value dates (the 1st and the 18th) on a notional ₹10,000 a month: 0.7% of the ₹6.2 lakh it grew to over 4.4 years.

Missing one instalment costs more than picking this date over a typical one.

The date with the highest XIRR and the date with the highest final value differ here, which points to noise.

A spread of 0.35 pp is hard to tell apart from the noise a history this short produces, so this verdict reflects the length of the history as much as the fund.

Each SIP date shows its full-history XIRR. Dates shaded as “higher than today” beat today’s date; the other shade fell short. Weakest to strongest across all 28 is 0.35 pp, and the deeper the fill, the further from today’s figure that date sat. Tap a date (1–28) to compare it with the named day; that does not change the answer.
