What happened — and what it teaches
In May 2008, the Nikkei 225 traded near 13,743 as the world economy teetered on the edge of a systemic credit crisis. Over the following months, Lehman Brothers collapsed, interbank lending froze, and risk aversion swept across global markets. Japanese equities were caught in a powerful downdraft as export earnings collapsed and corporate earnings forecasts deteriorated sharply.
By December 5, the index had fallen to 7,917.51, a loss of 42.4% from the May 12 starting level. The maximum drawdown reached 50.6%, with the largest single daily swing hitting 14.2%. Across the 144 trading days spanning May to December 2008, participants confront 25 decision points, 9 of which represent critical inflection moments.
This replay exposes how rapidly a trending market can reverse under liquidity stress. Participants must practice position sizing that accounts for fat-tail events, maintain discipline when volatility surges beyond historical norms, and resist the psychological trap of averaging down into a falling knife. The scenario strips away speculation to its essential test: can you make sound decisions when fear dominates price action and conventional valuation metrics no longer anchor expectations?
