Question 1

What is the Stock Market Time Machine game?

Accepted Answer

It is a free interactive game that drops you into 5 random historical stock market moments — from the 1987 Black Monday crash to the 2024 AI boom. You start with $10,000 and must decide whether to buy, hold, or sell in each round. Your final portfolio is compared against the S&P 500 and what Warren Buffett would have done.

Question 2

How does the stock market game scoring work?

Accepted Answer

After 5 rounds, your final portfolio value is compared against two benchmarks: the S&P 500 (simple buy-and-hold) and the 'Buffett Strategy' (buying during fear, holding during greed, and selling during euphoria). You receive a letter grade from A+ (Oracle of Omaha) to F (Emotional Trader) based on how close your returns match Buffett's.
