What happened — and what it teaches
The Jakarta Composite Index is Indonesia's primary stock market gauge, tracking the performance of the country's most liquid companies. In April 2015, the index stood at 5491.34, reflecting investor confidence in Southeast Asia's largest economy. Over the following seven months, a confluence of policy uncertainty and global market volatility created an environment where every trading session carried significant consequence.
From April to November 2015, the index fell to 4451.59, a decline of 18.9%. The market's maximum drawdown reached 25.0%, with the largest single-day move spanning 4.6%. Throughout this turbulent period, traders faced 25 decision points, with 9 deemed critical moments that could significantly alter portfolio outcomes.
This replay teaches that managing sustained downturns requires disciplined process and clear risk parameters. Participants learn to define acceptable loss thresholds before entering positions, avoiding the common pitfall of hoping for recovery in a deteriorating market. The psychological dimension proves equally important: maintaining composure when facing a 25.0% drawdown tests emotional resilience and forces honest assessment of one's risk tolerance.
