A fast investing game students can discuss
Students build a portfolio without company names, then compare results after the era is revealed. The surprise creates questions that a normal lecture slide rarely gets.
Suggested format
Give students 15–25 minutes to play on their own, then compare who beat the S&P 500 and which risks they took.
Topics it opens
Diversification, index funds, bubbles, crashes, interest rates, investor behavior, timing and the danger of looking only at winners.
No signup required
