Asset Analyzer use case
Compare historical day-of-month contribution timing for the same asset and sample period instead of guessing whether one recurring date mattered.
Best DCA Day is a contribution-timing use case inside Asset Analyzer. It holds the asset and sample period constant while varying the day of the month you contribute.
The result shows whether contribution timing had a measurable effect for a given asset and period.
For most assets and periods, the differences are much smaller than the effect of asset choice, contribution size, and time in market. The value of the view is calibration, not a promise that one calendar day is always superior.
Does this identify a universally optimal contribution day?
No. It identifies what happened in the selected historical sample. The result is specific to the asset, date range, and contribution schedule used.
