Just finished benchmarking free historical EOD data sources for backtesting global ETF allocation strategies without paying $99/mo for proprietary terminals. Combining Stooq CSV endpoints with Portfolio Performance XML exports works flawlessly!
Asset Class Weight TER 10Y CAGR (Real)
MSCI World 70.0% 0.12% 8.4%
EM IMI 20.0% 0.18% 5.1%
Global Agg Bond 10.0% 0.10% 1.2%
Stooq + ECB statistical data warehouse are honestly the most underrated free data sources out there.
Kann ich best??tigen! Nutze das gleiche Setup f??r meine monatlichen Rebalancing-Checks in Portfolio Performance.
If anyone needs an automated parser for the XML file format of Portfolio Performance, the schema is super clean to read.
