What happened — and what it teaches
The KOSPI 200 entered February 2020 as a mature, liquid index representing South Korea's largest companies. Over the 108 trading days from February 12 to July 20, 2020, participants in this replay confronted one of the most turbulent stretches in recent market history. With a maximum drawdown of 34.0% and single-day swings reaching 9.3%, the environment tested every trading framework, risk model, and psychological threshold. Eleven decision points—four deemed critical—divided the period into distinct choice moments where outcomes pivoted on judgment calls made under pressure.
The headline numbers tell a story of violent oscillation. The index fell from an opening close of 30540 to 29155, a net decline of -4.5%. Yet that modest final number obscures the journey: a plunge of 34.0% at maximum drawdown followed by a sharp recovery between March 23 and June 10. The largest single-bar move of 9.3% arrived without warning, capable of wiping out weeks of careful positioning in a single session. Participants who survived did so not by predicting these extremes but by managing their exposure when they arrived.
For decision training, this scenario strips away the comfort of hindsight. The 34.0% drawdown is not a number to be debated but a reality to be managed. Process matters more than prophecy: participants must decide when to add risk, when to reduce it, and how to maintain psychological equilibrium when 9.3% days arrive. The four critical decision points offer concentrated lessons in risk management, entry timing, and emotional discipline. The market's ultimate message is simple but hard: volatility is not danger, but unmanaged volatility is.
