Stock Market
In short
A stock market is a collection of buyers and sellers trading shares that represent ownership in companies.
In plain words
It is a place where people buy and sell small pieces of businesses. When you buy a share, you own a tiny part of that company. If the company does well, your share might become more valuable.
A simple example
If you buy one share of a tech company, you own a small slice of that business. If the company makes a huge profit, the price of your slice usually goes up.
Why it matters
It allows companies to raise money to grow by selling parts of themselves to the public. It also gives regular people a way to grow their savings by investing in successful businesses.
Easy to mix up
Do not confuse it with a commodities market, which is for trading raw materials like gold or oil instead of company ownership.
