What happened — and what it teaches

The Jakarta Composite Index entered 1998 under the shadow of mounting political tensions that would soon overwhelm Indonesia. Between January 5 and August 5, 1998, traders faced 144 daily bars of an era defined by uncertainty, riots, and the fall of a president. The decade of the 1990s had delivered few environments more treacherous for equity investors, and the market offered no clear roadmap through the chaos.

What unfolded was a study in volatility. The index ultimately closed the period at 441.78, representing a 7.5% recovery from an opening close of 410.83, but this modest headline number concealed a 29.8% max drawdown along the way. A single trading day saw a 14.0% move, underscoring how quickly positions could be made or destroyed. Navigating this required surviving the deepest dips before benefiting from any rebound.

The scenario presents 25 decision points across 9 critical junctures, demanding that participants confront risk management, emotional discipline, and the limits of analysis during systemic crises. How does one size positions when 14.0% single-day swings are possible? When does discipline become capitulation? These questions shape the educational value of reliving this period, not as investment advice but as a test of decision-making under the extreme conditions that defined the 1990s crisis in Jakarta.
