U-PAA - Protective Asset Allocation is a UCITS version of Keller & Keuning's PAA, for investors outside the United States who buy UCITS funds rather than US-listed ETFs.

The rules are unchanged: the six strongest of twelve risk assets, each still required to show its own positive trend, with a defensive share in short or intermediate Treasuries that grows step by step as market breadth weakens. The full logic is on the PAA - Protective Asset Allocation page. Because only the funds that hold each position change, the backtest is identical to the original's, month for month.

How Closely the Funds Match

  • Same or near-identical index. For most positions the UCITS fund tracks the same index, or the same index family, as the US fund it replaces.
  • Japan is held through a FTSE Japan fund in place of an MSCI Japan fund; the two indexes are very close.
  • U.S. real estate is the loosest match: the UCITS fund screens U.S. REITs for dividend yield and only comes in a distributing share class.
  • Commodities are held through a Bloomberg Commodity index fund in place of the US fund's optimum-yield index, so returns will differ somewhat.

Performance Highlights

The Ulcer Index measures how deep and how long drawdowns were, not just the single worst one: lower is better. UPI (Ulcer Performance Index) is return above T-bills per unit of Ulcer Index: higher is better.

Notes for Investors Outside the US

  • Results are in US dollars. The strategy is calculated on the history of the equivalent US funds, in US dollars. If you measure your portfolio in pounds, euros or another currency, your results will also move with the exchange rate.
  • Why UCITS funds. Irish-domiciled UCITS funds are the standard way for non-US investors to hold US markets. They often receive US dividends at a lower withholding rate than a non-US investor holding US-listed ETFs directly would, and they are not US assets for US estate tax purposes. Rules vary by country, so check with a tax adviser where you live.
  • Gold is held as an ETC. UCITS rules do not allow a fund that holds only gold, so gold is held through the iShares Physical Gold ETC, a security backed by physical gold. It is not a UCITS fund, but it is UCITS eligible and widely available to investors in the UK, Europe and elsewhere.
  • Listings. The tickers above are the London Stock Exchange USD lines unless noted. Most of the funds also trade in London in pounds and on European exchanges in euros, under the same ISIN, which is the surest way to find the right fund at any broker.

Who It's For

U-PAA - Protective Asset Allocation is for investors outside the US who want protection that scales with the danger rather than arriving all at once, built from UCITS funds and a physical gold ETC.


Past performance, including backtested results, is not indicative of future results. Backtested performance is hypothetical, does not reflect actual trading, and benefits from hindsight in the selection of strategy rules. U-PAA - Protective Asset Allocation is calculated on the history of the equivalent US-listed funds; the UCITS funds track the same or closely matching indexes but their returns will differ, including from fees, tax treatment and currency. Portions of the long-term history rely on reconstructed proxy data for funds that did not exist for the full period. Investors should carefully consider their risk tolerance and consult with a financial advisor.

Every figure is net of trading costs and computed from the same monthly data as the rest of the site, over the months all the portfolios shown have in common (Feb 1980 to Sep 2026). Returns before an ETF's launch come from a matching index, as explained in where the data comes from. Backtests are hypothetical and are not a promise of future results.
