You might have heard stories about how someone bought a new house or an SUV from the ‘stock market earnings’. There are stories of how people invested in equities and other securities, trusted the market, and became millionaires. Stock market fascinates everyone. Movies are made, scenes are shot, and stories are written about investors and traders with an adrenaline rush, looking to conquer the world.

If you are someone who wishes to start their investment journey and is a bit confused about how everything works, you have come to the absolute right place. Let us walk you through the stock market basics so that you can prepare yourself for a long and highly satisfying investment journey.

What are Stocks?

Ever wondered what you actually ‘own’ when you buy shares of a company on Upstox? You do not just bet on current prices, but own a small piece of a publicly traded company. Let us understand what is stock and how you can become a company’s potential investor.

Stocks represent ownership in a company. When you buy a company’s stock, you essentially purchase a small portion of the company, known as a ‘share’. This makes you, the investor, a shareholder in the company and the proportionate owner of the company. You can participate in voting (if holding equity shares) and in shareholder meetings.

A public company in India can issue shares when capital is required for expansion or growth. These shares, such as the BSE and NSE, are traded on the stock exchange. The value of a stock can rise or fall depending on how the company performs and how investors perceive its future potential.

What is Share Market?

The share market, or a stock market, is a platform where investors trade shares of publicly listed companies. It acts as a giant marketplace where stocks are bought and sold as per their demand and supply. The two terms (stock and share market) are often used interchangeably. However, in a share market, you can trade shares, whereas on a stock exchange, you can trade different securities such as bonds, mutual funds, derivatives, shares of a company, etc.

In India, the two major stock exchanges are the NSE (National Stock Exchange) and BSE (Bombay Stock Exchange). These exchanges facilitate transparent and regulated trading. Let us find out more about share market basics.

How Does the Stock Market Work?

You might wonder how the share market works. The process sounds complicated, but it is quite straightforward. Companies raise capital by issuing shares to the public through IPO (Initial Public Offering) or FPO (Follow-on Public Offering). Once these shares are allocated to the public, they are also listed on the stock exchanges to facilitate buying and selling between investors. Stock prices move based on supply and demand, influenced by factors like company performance, economic indicators, global events, and investor sentiment.

Brokers and platforms like Upstox act as intermediaries, allowing individuals to place buy or sell orders electronically. Behind the scenes, regulatory bodies like SEBI (Securities and Exchange Board of India) ensure fair practices, transparency, and investor protection.
