About Stoqlabs
Stoqlabs is a free backtest tool that shows how asset allocation strategies and portfolios you build yourself would have done, using real market prices updated every day.
Why we built it
Claims like “60/40 is enough” or “dividend ETFs beat growth” are everywhere, but they are rarely checked against data in your own currency. Stoqlabs lets you check them yourself, in won or dollars, including drawdowns and dividends.
What you can do
- Compare seven well-known strategies: 60/40, All Weather, the Permanent Portfolio, Dual Momentum and more.
- Build up to five portfolios of your own from US ETFs, leveraged ETFs, dividend stocks, Korean large caps and Bitcoin.
- See return, max drawdown, volatility and dividends in KRW, USD, EUR, JPY, GBP or CNY.
- Choose the period, the rebalancing frequency and whether dividends are reinvested.
Where the data comes from
- US stocks and ETFs: Tiingo end-of-day prices, adjusted for splits and dividends.
- Korean stocks, ETFs and indices: Korea Exchange (KRX) Open API.
- Exchange rates: the Frankfurter API (European Central Bank reference rates).
Prices are collected once a day after the market closes, so results reflect the previous close.
