What is Stock Market? | Basics of Share Market, NSE, BSE, SEBI, Investing & Trading Explained

📘 Etymology of Stock Market

The word “Stock” originated from the Old English word stocc, meaning tree trunk or foundation, symbolizing a source of growth.
The term “Market” comes from the Latin word mercatus, meaning a place where trade happens.
Thus, the Stock Market literally means a place or platform where the ownership (stocks or shares) of companies are bought and sold.

📜 Short History of the Stock Market

The concept of stock trading began in the 1600s when the Dutch East India Company became the first company to issue shares to the public.
The Amsterdam Stock Exchange (1602) is considered the world’s first official stock exchange.
In India, the Bombay Stock Exchange (BSE) was established in 1875, making it Asia’s oldest stock exchange.
Later, the National Stock Exchange (NSE) was launched in 1992, bringing electronic and transparent trading to India.

💡 What is Stock Market? (Definition for Beginners)

The Stock Market, also called the Share Market, is a platform where buyers and sellers trade ownership of companies in the form of shares.
It helps companies raise funds for business and gives investors a chance to earn profits through dividends or price appreciation.

In simple words:

The stock market is like a big supermarket — but instead of vegetables or clothes, people buy and sell shares of companies.

📈 Meaning of “Stock”

A Stock represents a part of ownership in a company.
When you buy a stock, you become a shareholder, which means you own a small portion of that company and can benefit from its profits.
