What happened — and what it teaches
The scene places you inside one of the Chinese equity market's quieter but instructive corrections of the early 2010s. Starting May 4, 2012, the CSI 300 index began a sustained retreat that would test the discipline of any participant managing risk in real time. With 150 daily bars stretching to December 25, the scenario captures a complete market cycle—from early decline through capitulation and eventual stabilization—offering a realistic training ground for navigating sustained downside pressure.
The numbers tell the story succinctly. The index fell from 2.71 to 2.45, a net decline of -9.6%, yet the maximum drawdown reached 21.0%, revealing how temporary paper losses can far exceed the final outcome. The largest single trading day saw a 5.3% move, underscoring the kind of intraday volatility that forces split-second position management. Eleven decision points punctuate the replay, with four deemed critical—the moments where strategic choices between holding, reducing, or repositioning could determine whether a participant preserved capital or accumulated regret.
For decision training, this replay is most valuable not as a forecast exercise but as a stress test of process and psychology. Facing a 21.0% drawdown while the ultimate loss was only -9.6% forces the question: would you have held through the deepest pain, or bailed too early? The presence of 5.3% single-bar moves highlights how volatility itself can become a behavioral trap. Navigating this scenario well requires pre-defined rules, emotional calibration, and the humility to accept that surviving the drawdown is separate from predicting the bottom.
