Most people I talk to think the share market is either a casino or a magic money tree. Both are wrong. It is a system — a marketplace where companies sell tiny pieces of themselves to raise money, and where ordinary people can buy those pieces and grow their wealth over time. That is it. No mystery. No secret club. In this guide I am going to walk you through how it actually works, in the same plain way I explain it to my friends who are starting out.

What is a share, really?

A share is a small piece of a company. When a company like Reliance Industries needs money to build a refinery or launch a new business, it can borrow that money or it can sell off pieces of itself to the public. Each piece is called a share or a stock. If a company has issued 100 crore shares and you own 100 of them, you legally own a 0.0000001% slice of that company. That is a tiny slice, but it is real ownership. You get a vote on certain decisions, you get a cut of the profits (called dividend), and if the company grows in value, your slice grows with it.

Here is the part most beginners miss. You are not just betting on a price going up and down. You are becoming a part-owner of a real business. The stock price is just the market's daily guess at what that business is worth. Over the long run, that guess tracks how well the business actually performs. Over the short run, it tracks human emotion. That distinction matters more than anything else you will learn.

What is a stock exchange?

A stock exchange is just the marketplace where shares are bought and sold. India has two main ones — the NSE (National Stock Exchange) and the BSE (Bombay Stock Exchange). The BSE is the older of the two, founded in 1875, making it the oldest exchange in Asia. The NSE came along in 1992 and quickly became the more popular venue because of better technology. Most stocks are listed on both exchanges, so you can buy the same share on either one.

Each exchange has a flagship index that summarises how the market is doing on a given day. NSE has the Nifty 50, which tracks the top 50 companies. BSE has the Sensex, which tracks the top 30. When news anchors say the market is up 1%, they almost always mean one of these indices.

How does the share market actually work?

The process is more orderly than it looks on TV. Here is the chain end-to-end, step by step:

  1. A company needs capital to grow. It decides to go public.
  2. It launches an Initial Public Offering (IPO) where it sells fresh shares to the public for the first time.
  3. After the IPO, those shares are listed on the exchange and anyone with a demat account can trade them.
  4. Every time you place a buy or sell order through your broker (Zerodha, Groww, Upstox, etc.), it goes to the exchange.
  5. The exchange matches your buy order with someone else's sell order at a price both sides agree on.
  6. The trade settles in T+1 day — the shares land in your demat account and the money moves out of your bank.

Price moves on simple supply and demand. If more people want to buy a stock than sell it, the price ticks up. If more want to sell, it drops. That is the entire engine. Everything else — news, earnings, RBI announcements, foreign investor flows, social media hype — just nudges that buy-sell balance one way or the other.

How do people actually make money in the share market?

There are two ways, and you should know both because most beginners only think about the first one:

1. Capital gains

Buy a stock at one price, sell it later at a higher price. The difference is your profit. If you bought 100 shares of TCS at ₹3,000 and sold them at ₹3,500, that is ₹50,000 in capital gains. Over 10–20 years, the compounding here is what creates serious wealth — the long-term return of the Nifty 50 has been roughly 12–14% per year. ₹1 lakh invested in Nifty in 2015 would be around ₹3.5–4 lakh today, without doing anything clever.

2. Dividends

Many established companies pay a portion of their profits to shareholders every year. ITC, Coal India, ONGC and most PSU stocks are known for solid dividends. If you own 1,000 shares of a stock paying ₹20 per share annually as dividend, that is ₹20,000 a year in passive cash flow — and the shares themselves are still yours.

Reality check
The share market is not get-rich-quick. SEBI's own data shows that about 90% of intraday traders lose money. The investors who actually build wealth are the boring ones who buy good companies and hold for 10+ years. Patience is the actual skill.

Risks you need to understand before you start

Three honest things nobody tells you when you sign up for that flashy trading app:

How to actually start — the 5-step path I recommend

  1. Open a demat and trading account. Read my demat account guide for which broker to pick. Zerodha or Groww for most people.
  2. Start with index funds, not individual stocks. A Nifty 50 Index Fund gives you all 50 top companies in one purchase, with the lowest fees. You don't need to pick winners — you just need the market to grow over time.
  3. Set up a small SIP. Even ₹500 a month is fine. See SIP vs Lumpsum for why monthly investing beats trying to time the market.
  4. Learn before you trade. Spend the first 6 months just watching, reading, and putting in small amounts. Read my blue chip stocks guide and PE ratio guide to start understanding what makes a company good.
  5. Know the tax rules. Capital gains in India have specific tax treatment. See my stock market taxes guide so you are not surprised in March.

Where to track everything

I built stocks.srjahir.in partly because I was tired of how cluttered other financial sites are. On the home page you can see live Nifty, Sensex and Bank Nifty, the latest market news, today's top gainers and losers, the upcoming IPO calendar, and a clean SIP calculator. All free. No popups.

Once you have your demat account open, come back to this site — bookmark the home page — and you will have everything you need to track the market without 18 tabs open.
