Fund fees and facts
Fees (TER) and payout policy from issuer documents, checked against a fund data provider. Fund profiles and holdings from issuer files and data providers. A fee nobody publishes stays blank instead of showing 0%.
Built in Zurich, Switzerland
A UCITS ETF comparison site, built in Zurich.
Bullrun is built and run by Ferenc Kuntic in Zurich, Switzerland. It compares UCITS ETFs by fee, domicile, payout and where they trade, for investors in Europe and Switzerland, and keeps research on companies worldwide alongside.
Who builds it
An independent project, paid for by its users.
No bank, broker or fund issuer owns Bullrun, and none can pay to change how funds are ranked: index pages sort funds by their published fee, cheapest first.
It is paid for by the people who use it, through Pro subscriptions, pay-as-you-go research credits and donations. There are no ads. See pricing.
Who it is for
UCITS ETF investors in Europe and Switzerland.
Most people in Europe who invest on their own buy index funds, and the same index is sold by many funds at very different prices. Bullrun puts every UCITS fund on an index side by side, cheapest first, with its domicile, whether it pays out or accumulates, and which exchanges it trades on, including the line a German broker uses by default. Start with the index comparisons or the A-Z list; fund pages are also in German and French.
The same choices face investors in Singapore, Hong Kong or the Gulf who buy Irish-domiciled ETFs, so the site works for them too.
Global stock research sits alongside: company pages with financials taken from filings, a screener, market data and a risk board.
Where the data comes from
Public filings, fund documents and market data.
Company financials come from the filings companies make to regulators, and fund fees from the documents issuers publish, with data providers filling the gaps. How each source is used is on the methodology page, the open sources are credited on the data sources page, and licensing terms are on the data license page.
Company financials
SEC EDGAR XBRL filings for US companies and ESEF annual reports for European and UK ones, with data providers filling the gaps.
Prices
End-of-day closing prices from market data providers. Prices are not live.
Economy and markets
The Federal Reserve Board, the US Treasury, the US Energy Information Administration, the US Census Bureau, the US Bureau of Labor Statistics, FRED, the World Bank, OECD, BIS, the IMF, Eurostat, and national central banks and finance ministries for economic data; GDELT and other providers for news. ISINs and cross-listings from public registers and data providers.
How the numbers are made
Descriptive numbers, with the method written down.
The valuation figure says how a company's P/E compares with the multiple its fundamentals usually command. It does not predict returns, and the methodology page shows the test that says so.
Risk scores read strain out of a company's own filings, and a dial with too little data is not shown rather than scored as safe.
The methodology page explains both, along with how fund fees, index families and listings are chosen.
Not investment advice
Information, not advice.
Bullrun is a research and education tool. Nothing on it is a recommendation to buy or sell anything, and none of it is tailored to your situation. Read a fund's key information document (KID) and prospectus before you buy, and talk to a licensed adviser if you need advice.
