Lump sum vs drip purchasing

Two patterns: invest available cash all at once (lump sum) or buy in instalments over time (a savings plan). Both are descriptions, not Finmon recommendations.

In more detail

Questions, not recipes: when is the cash truly available? How tolerable are short-term swings? What fees arise per purchase? If the market rises after a lump sum, drip often lags; if it falls afterward, drip can catch lower average prices. Nobody knows that in advance.

Background

Finmon does not say you should invest, and it names no product. The trade-offs are questions: how soon you need the money, your time horizon, fees, and how much swing you can live with. This sits next to spreading purchases over time, compound growth, and risk.

An example

You have €6,000 free. Variant A: all today. Variant B: €500 for 12 months. Which ends better depends on the path; Finmon does not decide that.

A common misconception

There is one universally right choice between lump sum and drip.

Both are patterns. Which looks better afterward depends on the price path and your constraints.
