How it is calculated

Building blocks: ETFs already available in every Watchlist — the same prices as in the Community-Backtests, updated every night, in euros. You can recalculate every allocation in the backtest with the same securities.

Before tax: starting value €10,000, without costs and taxes, distributions reinvested, back to the target allocation on the first trading day of every year. Risk-free rate for Sharpe and Sortino: 0 %.

After tax: the same calculation with €100,000 and German flat-rate tax of 26.38 % without church tax, partial exemption per ETF, saver's allowance of €1,000, advance lump sum and tax on gains when rebalancing; at the end of the period everything is sold. Gains on gold are taxed like capital gains — with Xetra-Gold they would be tax-free after one year, so the after-tax figure tends to be too low there.

All portfolios end on the last trading day of the previous month and are recalculated every month.

Descriptive, not a recommendation: this page shows how well-known allocations would have developed in the past. Which one suits you depends on your goals and your situation.

⚠ Notice: The results were calculated after the fact from historical prices. They do not show the performance of an actually managed portfolio. Past performance is not a reliable indicator of future performance. Paperball does not provide investment advice or investment recommendations.
