Your SPPW

The rule

  1. The money waiting to go into SPPW is spread evenly over the Fridays until the next dividend (mid-April).
  2. The further SPPW is below its highest price, the more you buy: +25% of the normal amount for every 1% it is down, up to 5× the normal amount (reached at −16%).
  3. No all-in when SPPW falls: each buy is capped, and it keeps money back (a quarter of the normal amount at the start of the year, for every week still left) so there is a buy every week until the dividend — it never buys less than this week's normal amount, and the last week before the dividend buys what is left. No extra buys between weeks.
  4. The fall is measured at the lowest price since the start of last week — last week's closes, this week's closes and the live price — against the highest close ever. Each new close can only push the week's amount up; while Xetra is open the live price counts too. Best: buy on Monday (that is what was tested); any day that week is fine.

Your Mac's 19:00 notification and this page use the same rule (the lowest price since the start of last week). On Tuesday–Thursday your Mac shows a preview of next week, while this page keeps showing this week's amount until Friday's close. Buy each week through one of them only: pressing "I bought" here does not tell your Mac. Record each buy with "I bought it" so the weekly spread keeps track; typing a new amount of money waiting (for example after the dividend) restarts the spread from that amount.

Each year: how much can I spend?

What is left of a year's income after a year of spending goes into SPPW, spread weekly from the April dividend, growing at the chosen return above inflation. Moving these never changes this week's order above. A smooth average, not a forecast.

Into SPPW per year (income − spending)
Goal reached
After 10 years

Grey = money you put in. Blue = growth on top (compounding). Dashed = goal. Inflation 2% a year (euro area), fund cost 0.12%; new money starts with the next April dividend and grows with inflation.

If things go wrong

  1. No yearly income, or less than your income-stop amount: stop buying SPPW that year (set the amount once under "Your numbers", and enter the income when it arrives).
  2. A crash: the rule buys more by itself — +25% per 1% fall, up to 5× a normal week from −16%, every week until the dividend, with no all-in. Never sell SPPW because it fell.

This page only covers SPPW. Your safety money (what is never invested, bills, the interest-rate check) is handled by the daily 19:00 notification on your Mac (uv run stocks plan).

Why this rule

Tested on 10-year periods of the MSCI World, the S&P 500 and the DAX, after XTB costs and tax, in today's euros: about 0.2–0.7% more after 10 years than the previous rule (roughly €2,000–9,000), and about 0.5–3% less than putting each dividend in at once (roughly €5,000–48,000) — the price of buying calmly. In every historical test there was a buy every week, and the biggest week was 5× a normal week; the previous rule could put the whole dividend in at once and then buy nothing for up to a year. It is not ahead every time: in the worst start tested (the DAX from October 2002) it ended 5% behind the previous rule.

How far these numbers go: daily prices of the MSCI World index (1985–2026, without dividends), an accumulating MSCI World ETF (2009–2026), the S&P 500 and the DAX, plus 4,000 simulated futures; the money waiting held in a money-market fund. Checked after the main study, not a forecast; a second reviewer reproduced every number.
