Back-testing

How back-testing works on OPTO.

Updated this week

What is a Backtest?

A backtest is a interactive tool that simulates an investment strategy and how it may have performed in the past using historical data. It's important to know what assumptions go into these and how they differ from trading on the OPTO app.

Key Points to Understand

  • Hypothetical Nature: All backtest results are hypothetical and benefit from hindsight. If a backtest comprises stocks that have gone up over the past year, it's performance is not indicative of any possible future returns.

  • Past Performance: Past performance is not a reliable indicator of future performance.

  • Estimation: Backtests estimate how a model performs under specific market conditions and are not recommendations for actual trading decisions in the past or the future.

  • Variability: Results may vary with each use and over time.

Data Sources

  • Backtests: For backtests on OPTO, we use daily closing prices from Morningstar. These prices are not adjusted for corporate actions. These prices do not represent real quotes from any points during the trading day. When trading on the OPTO platform, real intraday prices are used and will differ from backtest prices.

  • Universe of Investments: This universe of assets available to back-test includes the stocks and ETFs that OPTO users may trade, which are the fractionable stocks our brokerage partner Alpaca has approved. Please note that other investments not considered and outside the universe of investments on OPTO may have characteristics similar or superior to those being used in the backtest.
