The thousand most relevant listed companies in the world on one screen. Sort by return, size, sector, currency, volatility or drawdown, and open any name for its price history, rebased to 100 or as an actual share price.

How the main markets, sectors, countries, currencies, rates and credit behaved through the first half of 2026, with seven classic model portfolios read as references. An examination, not a recommendation.

Seven passive, total-return benchmarks built from low-cost ETFs, ordered from conservative to aggressive. Compare ten years of performance and risk, simulate the drag of costs, and see exactly what each portfolio holds, so you can judge your own against a clear reference.
