What happened — and what it teaches
In the spring of 2015, global markets faced mounting uncertainty as China's overheated stock market began its dramatic unwinding. The CAC 40, France's flagship equity index, entered a challenging period as ripples from the Chinese selloff reached European shores. Investors navigated 144 daily bars over nearly seven months, with 25 decision points including 9 critical junctures where positioning choices could significantly alter outcomes.
The index declined from 5192.64 to 4911.17, representing a 5.4% loss, though the damage could have been far worse—maximum drawdown reached 17.6%. Volatility proved relentless, with the largest single session move spanning 5.3%, testing the resolve of even seasoned participants. The extended timeframe allowed fear and uncertainty to compound, transforming what began as a measured correction into a sustained confidence crisis.
This replay trains participants to confront cognitive traps that emerge during prolonged drawdowns: the temptation to abandon discipline when losses mount, the difficulty of maintaining perspective when headlines dominate, and the challenge of distinguishing signal from noise in volatile conditions. By replaying authentic market pressure without real capital at stake, learners develop the emotional resilience and systematic processes essential for navigating periods when the crowd turns cautious and the path forward remains unclear.
