What happened — and what it teaches
The summer of 2008 found the CAC 40, France's flagship stock index, navigating one of the most treacherous periods in modern financial history. From June 2 to December 18, 144 trading days would test every participant in the market as the foundations of the global banking system began to crack. What had seemed like temporary turbulence revealed itself to be a systemic crisis of confidence, with interbank lending freezing and major institutions facing existential questions. This replay places you in the market as the narrative unfolds day by day.
The numbers tell the story starkly: the CAC 40 fell from 4935.21 to 3234.15, a decline of -34.5%, with a maximum drawdown of 42.2% testing all who held positions through the turmoil. Volatility was extreme, with the largest single daily move reaching 11.2%—a magnitude that could wipe out weeks of careful positioning in hours. Across these 144 sessions, 25 decision points emerged, of which 9 were critical junctures where prior assumptions had to be re-examined against rapidly evolving reality.
This replay is not about predicting the bottom or calling the rally. It is a training ground for the decision-making process itself: how to size positions when uncertainty is high, how to manage risk when correlations break down, and how to maintain discipline when psychology tempts you toward panic or euphoria. Facing these 25 decisions, you will experience firsthand the cognitive load of a crisis unfolding in real time, building the kind of pattern recognition that only comes from immersive practice.
