What happened — and what it teaches
In early 2015, the Shanghai Composite Index entered a phase of aggressive speculative expansion driven by abundant leverage and euphoric sentiment. Over 150 trading days spanning from January 7 to August 14, market participants navigated a period where momentum dominated fundamentals, and policy signals frequently shifted market direction. This scenario captures the essence of a bubble environment where the line between rational valuation and pure speculation blurred rapidly.
The index rose from 3373.95 to 3965.33, a gain of 17.5%, before experiencing a crushing 32.1% drawdown. The volatility was extreme, with the largest single-day move reaching 8.5%. Participants faced 26 decision points throughout the period, of which 9 were deemed critical, demanding split-second choices amid rapidly changing conditions.
This replay trains traders to recognize the psychological traps of bull markets: the seduction of momentum, the difficulty of contrarian exits, and the danger of late-stage overconfidence. By confronting these 26 decision points with simulated capital, learners develop discipline around position sizing and emotional control without the risk of real losses.
