What happened — and what it teaches
The Portuguese PSI 20 index, Portugal's flagship equity benchmark, entered a pronounced correction phase during the late summer and autumn of 2014. This six-week replay window captures the index as it navigated a challenging period of sustained downward pressure, testing investors' ability to manage risk through increased volatility. The scenario presents a realistic environment where preserving capital while maintaining discipline becomes the primary challenge for participants stepping through authentic market data.
The index slipped 6.5% from 5507.64 to 5150.7 across the 60-bar dataset, with a maximum drawdown reaching 18.8%. The largest single-day move of 3.3% tested stop-loss discipline and position sizing assumptions. Participants faced 11 decision points, including 4 critical junctures where directional conviction and risk management choices would significantly impact simulated portfolio outcomes through the drawdown period.
This replay cultivates decision-making under pressure by placing participants inside a genuine correction rather than a synthetic scenario. The teachings center on process discipline—sticking to pre-defined rules when emotions run high—risk calibration across an extended decline, and psychological resilience when portfolios trail expectations. Navigating a 18.8% drawdown without abandoning strategy builds the mental frameworks essential for surviving volatile market environments historically.
