Event Replay
What happened — and what it teaches
The Jakarta Composite Index enters a 144-day replay window from December 16, 1997 through July 22, 1998, a period that straddles one of Southeast Asia's most turbulent economic moments. Indonesia, swept up in the regional financial contagion, faced simultaneous currency collapse, banking sector stress, and political uncertainty. For market participants operating in that era, navigating this environment meant confronting questions about liquidity, policy response credibility, and the limits of valuation frameworks when fundamentals were shifting daily.
The index closed the period at 483.05, up 35.5% from the 356.39 opening level. Yet this headline gain conceals a journey marked by severe intraday volatility, including a largest single-bar move of 14.0% and a maximum drawdown of 29.8% from peak. Those who entered the period looking only at directional bias would have missed the structural damage inflicted during the drawdown phase and the psychological strain of maintaining discipline when price action turned violent.
This replay places trainees at 25 decision points, 9 of them flagged as critical, across the 1990s era. The core training value lies not in calling the direction but in experiencing how volatility compounds decision fatigue, how drawdown psychology diverges from risk management logic, and how process must be separated from outcome. Surviving theJakarta scenario requires a rules-based framework tested against a market that offered no stable footing.
