What happened — and what it teaches
In the summer of 2015, China's CSI 300 index entered one of its most treacherous periods since the financial crisis. From late July through early September, spanning 30 trading days, the market navigated the aftermath of an unprecedented bull run that had pushed valuations to unsustainable levels. For investors and traders entering this replay, the stakes were clear: how would they respond when a market they'd grown accustomed to moved decisively against them?
The data tells a stark story. From a starting close of 3.8, the index descended to 3.38, representing an 11.1% decline over the replay window. Yet the headline figure understates the true volatility—maximum drawdown reached 28.2%, with individual sessions seeing moves as large as 9.9%. Participants faced 7 decision points, of which 3 were critical inflection moments where positioning decisions carried heightened consequence. The brutal arithmetic of sustained drawdown tested every assumption about risk tolerance.
This replay extracts enduring lessons for decision training. The gap between headline decline and actual underwater exposure—28.2% versus 11.1%—illustrates why peak-to-trough analysis matters more than simple endpoint measurement. Seven decision points demand consistent process over improvisation. Three critical junctures remind us that a handful of choices drive disproportionate outcomes. The 9.9% single-session shock shows why position sizing and contingency planning cannot be afterthoughts. Strip away the specific market, and what remains is a universal test of discipline under pressure—exactly the competency this simulation develops.
