Stock Backtest Performance and How Each One is Done

Along with the predefined value stock screens, a detailed discussion and stock backtest is performed on each stock screen.

Rather than just creating new value strategies and publishing it, I want to make sure that it has a good long term track record which is why a stock backtest is performed and refined before the screens are published.

Here are a few common stock backtesting criteria across all the value screens.

  • No financial stocks
  • No ADR’s
  • No OTC stocks
  • Minimum volume required
  • 15 positions
  • Slippage range of 1% to 5% depending on strategy

All the screens are currently 100% long. No short screens available at the moment.

To learn more about each stock backtest, read about each one using the links below.
