What happened — and what it teaches
In the autumn of 1987, the FTSE 250 entered one of the most punishing stretches of its history, with the replay window running from 23 September to 25 November and capturing a market whose confidence had already begun to fray. Across those 46 daily bars, the index slid from a close of 2708.7 to 1823.1, a decline of 32.7% in barely two months. The atmosphere was one of accelerating stress: investors watching not just a single bad session, but a regime shift in which volatility itself became the story. What made the period especially demanding for any decision maker was the density of turning points: nine decision points, three of them flagged as critical, so the replay forces the participant to act at moments when conviction is hardest to maintain.
The price path was defined less by a slow grind than by violent steps. A maximum drawdown of 39.8% marked the depth of the stress, while the largest single-bar move reached 11.3%, a reminder that in crash conditions capital can evaporate before any rational rebalancing is possible. From the opening close of 2708.7, each downward extension tested whether the prior low was a floor or a waypoint, and the 32.7% slide to 1823.1 closed a chapter in which traditional support levels were repeatedly overrun. The 46-day span is short enough to remember each session vividly, yet long enough to expose how quickly compounding losses erode both portfolio and composure.
For decision training, the scenario offers three lessons that travel well beyond 1987. First, process discipline matters more than prediction: with nine decision points concentrated in a high-velocity tape, rehearsed rules for sizing, hedging, and stepping aside outperform improvised calls. Second, risk must be measured against the worst bar, not the average one, since the 11.3% single-day move shows how ordinary position sizing can become ruinous under shock. Third, psychology is the real edge: the three critical decision points are where fear, denial, and capitulation compete, and the AI coach review invites participants to confront which emotion they obeyed and at what cost.
