What happened — and what it teaches
In early 2018, the CSI 300 entered a sustained correction that would test every investor's discipline and decision-making framework. This replay spans 150 trading days, from January through mid-August, and presents participants with 11 decision points—including 4 critical junctures—where strategic choices could mean the difference between preserving capital and compounding losses. The scenario is designed to simulate real pressure without real stakes.
The index declined from 4.19 to 3.34, representing a 20.3% loss over the period. What made this correction particularly challenging was not merely the aggregate decline but the underlying volatility: a maximum drawdown of 24.1% tested portfolio endurance, while the largest single-day move of 4.5% introduced sudden reversals that could trigger emotional responses. Participants who held static positions through the full drawdown faced significant paper losses, while those who acted rashly at market bottoms locked in losses unnecessarily.
This replay distills lessons in three essential areas: process discipline during extended downturns, risk management when drawdowns exceed expectations, and psychological resilience when facing a market that falls further than anticipated. The 11 decision points force deliberate engagement with uncertainty—participants cannot simply set and forget, but must continuously reassess position sizing, timing, and conviction. The educational value lies not in predicting market direction but in building the frameworks and emotional regulation needed to navigate whatever conditions emerge.
