StockSim: Learn Investing

Learn investing, one practice decision at a time. StockSim helps kids and families explore the stock market with pretend money. Build a portfolio, research investments, make buy and sell decisions, and see how those decisions affect an account over time. START SMALL Begin at $0 and make your first pretend deposit. The suggested amount is $100, and you can choose another amount. Buy fractional shares to practice with a few dollars at a time. Deposits and withdrawals appear in your activity history, so adding cash is kept separate from investment gains. BUILD YOUR OWN PORTFOLIO Explore stocks and ETFs using dated market observations. Follow your holdings, cash balance, allocation, and portfolio history. Review each practice trade and see what changed afterward. RESEARCH BEFORE YOU DECIDE Read simple business summaries, explore price charts, write your own research notes, and set a price to watch. Use StockSim together to discuss what a company does, what could go well, and what could go wrong. LEARN STEP BY STEP Work through 23 short lessons about shares, funds, diversification, charts, gains and losses, and thoughtful investing. Each lesson includes an explanation, an example, and an activity or discussion prompt. Mark lessons complete as you learn. MADE FOR FAMILIES StockSim is free, with no ads, subscriptions, chat, or news feeds. There are no banking or brokerage connections. Portfolio activity, research notes, watch targets, lesson progress, and settings stay in local app storage. All money and trades are simulated. Prices are dated market observations, not real-time quotes. If market data is unavailable, StockSim shows that clearly instead of inventing a price. Practice trades fill immediately at the displayed price, which simplifies how real markets work. StockSim is an educational tool, not investment advice, and does not predict or promise investment returns.
