What happened — and what it teaches
In early 2020, Portugal's benchmark PSI 20 index entered a period that would test every trader's conviction. Global health concerns were translating into economic uncertainty, and financial markets worldwide faced an environment few had navigated before. The scenario invites participants to step into that moment—44 trading days where the index descended from stability toward deep losses, with 8 decision points punctuating the decline and 3 critical junctures demanding decisive action.
The numbers tell a stark story. The PSI 20 fell from 5225.04 to 3993.57, a -23.6% decline that unfolded across 44 daily bars. The maximum drawdown reached 33.8%, and the largest single-day move hit 9.8%—volatility that could devastate concentrated positions. This was not a gradual erosion but a descent marked by sharp, sudden moves that challenged any portfolio constructed without adequate buffers. The replay captures the texture of those sessions: the mounting tension, the shifting sentiment, the moments when inaction felt riskier than action.
For decision training, this scenario strips away the comfort of hindsight. Participants must manage risk in real time, confronting the psychological pull of panic selling near bottoms and the temptation to hold falling assets in hope of recovery. The three critical decision points highlight how a single choice—entry, exit, or sizing—can define outcomes when volatility is extreme. The lesson is not about predicting the next crash but about building process discipline that survives one.
