Mystery Market Event

Teach reaction discipline.

StockSt uses fictional currency and simulated shares for education only. This is not investment advice.

Setup

Announce that a major event will occur in five minutes, without revealing what it is.
Students decide whether to buy, sell, or hold and write their reasoning before the event.
Reveal the event and compare what happened.

Give credit for a clear written rationale made before the event. Do not give extra credit for lucky guesses.

['Who reacted calmly?', 'Who traded based on fear or excitement?', 'Which decision process produced the best outcome?']
