What happened — and what it teaches
The KOSPI 200, South Korea's benchmark small-cap index, entered a correction phase during 2015. This replay spans from early March to mid-October 2015, covering 150 trading days of significant market turbulence. The scenario captures a period where global growth concerns and regional uncertainties weighed heavily on investor sentiment, creating an ideal training ground for those seeking to understand how downtrends develop and test resolve.
The index fell from 25810 to 24620, a -4.6% decline. Yet the headline number obscures the true volatility experienced: maximum drawdown reached 19.2%, more than four times the net loss, while the largest single-bar move was 3.0%. This disconnect between aggregate decline and intraday swings reveals the emotional toll of sustained corrections. Participants navigate 11 decision points, with 4 designated as critical moments that demand clear directional conviction or disciplined hedging.
This replay sharpens decision-making under adverse conditions. Traders must practice sizing positions when drawdowns extend well beyond initial expectations, resisting the urge to average down blindly or exit in panic. The scenario trains psychological resilience by exposing participants to realistic volatility spikes, helping them develop checklists for maintaining process when emotions run high. Such experience builds the composure needed to execute strategy consistently across different market regimes.
