The Big Market — Money Square · Investopia
In a market, prices change with supply and demand. Investopia simulation for ages 10–17 with fictional LeoCoins; not financial advice.
In a market, prices change with supply and demand. The first shares began here too.
The Story
When lots of people want strawberries and there aren’t many, the price goes up. When there are too many strawberries, the price goes down. That’s supply and demand.
In 1602, in Amsterdam, the Dutch East India Company started selling shares to the public and people began trading them between each other. This is one of the first examples of a stock market. Today, in Portugal, shares are traded on Euronext Lisbon. Share prices go up and down, and nobody knows for sure which way they'll go.
Key Ideas
- Supply: How much of something is available to sell.
- Demand: How many people want to buy that thing.
- Share: A small piece of a company.
- Stock exchange: Where people buy and sell shares.
Step by Step
- There are few strawberries early in the season.
- Lots of people want strawberries, so the price goes up.
- Farmers pick more strawberries.
- Too many strawberries, so the price goes down.
- The price settles where buyers and sellers agree.
Your Turn
Make a pretend market at home with trading cards or fruit: if there are only a few, how much would you ask? And if there’s a lot?
