Daily stock market game: trade 20 weeks of real history, then guess the year.
Underfolio is a daily stock market game built on real history. Each day you get 20 weeks of real stock prices with the date hidden. Trade it one week at a time, then guess what year it was. Every Daily Drop starts you with $10,000 in game money and every stock that traded in that stretch. Read the prices, the charts and the market numbers, buy, sell or short, and move the clock forward a week. After 20 weeks you lock in a year. You see how you did against the whole market and how close your guess was. • Real historical prices for thousands of US stocks, from the 1970s to the 2020s • One new Drop every day, the same for everyone • A trading simulator scored against the whole market, not just against zero • Guess the year: the exact year earns the full bonus, one year off earns half • Copy your result grid and share it • Keep a daily streak, with freezes earned for the days you miss • An optional reminder once a day, at a time you pick No account and no sign-in: open the app and play. When a Drop makes you curious about what really happened, one tap opens Underfolio's research in your browser: what happened in that era, company pages, and this day in stock market history. Free. No ads. Nothing to buy. Needs an internet connection. Underfolio is an investing game and learning tool built on historical market data. It is not investment advice, and no real money is involved. Today's Drop is ready. What year was it?
