What is the Stock Market?

The stock market is an organised place where people buy and sell small ownership parts of listed companies. A listed company is one whose shares can be bought and sold on an exchange. The word organised matters, because the buying and selling follow written rules, and are not private bargains between strangers.

Picture a sabzi mandi, but for parts of companies. Buyers and sellers meet in one place, under a rule book and an inspector. The picture stops working in one place. In a mandi a seller's board often sets the rate, but here prices come from buyers and sellers agreeing with each other.

Three parts make up the market. The exchange is the marketplace itself, such as NSE (National Stock Exchange) or BSE (earlier called the Bombay Stock Exchange). A broker is a registered firm that carries your orders to it. SEBI, the regulator of the securities market, makes and enforces the rules for everyone.

Take Sabzi Wala Foods Ltd, an imaginary company. It has 10,00,000 shares, and each share trades at ₹200. If the price stays there, one share costs ₹200 once your account is ready, which section 6 explains. We shall follow this one company through the whole lesson.

People often call the market a casino, or think a share is the company's own shop. Neither is right, because a share is a part of a real business. Knowing what the market is does not tell you whether any price is fair, or whether you will earn anything from it.

A share is one equal part of a company. Owning it makes you a part-owner, called a shareholder. The word equal is important. Every share of the same company is the same size, so a person with ten shares owns exactly ten times as much as a person with one.

Think of a family-run shop split into 10 lakh equal parts, like one roti cut into equal pieces. Each piece is the same size. The picture stops working in two places. Shareholders do not run the shop or take goods home, and parts can be sold to strangers.

Sabzi Wala Foods Ltd has 10,00,000 shares. The founders hold 8,00,000 shares, which is 8,00,000 divided by 10,00,000, or 80%. The public holds the other 2,00,000 shares, which is 20%. The two parts add up to the whole company, so nothing is left out. Writing each part as a percentage is a handy habit, because a percentage shows at a glance how big a holding is.

Now meet Asha, a reader who owns 10 shares. Her part is 10 divided by 10,00,000, which is 0.001%, or one in 1,00,000. It is a very small part, but it is a real one. She is a shareholder in the same way the founders are, only with far fewer shares.

A common mistake is to think more shares means more control or a bigger company. More shares only means a bigger part of the same company. This does not tell you what the share is worth, because that depends on its price. Two people can own the same company in very different amounts, and the company stays exactly the same size throughout.

The market lets companies raise money from many people, and lets people own a part of a business. Two needs meet in one place. The company needs money to grow, and the saver wants a part in that growth. Neither could easily find the other without the market.

Think of neighbours pooling money to open a new shop, and each getting a part of its profit. Each puts in a small amount, and together they have enough. The picture stops working here. A chit fund pays fixed amounts, but a share promises nothing. The neighbours know each other, while the savers in a market are usually strangers.

Sabzi Wala Foods Ltd wants ₹3 crore for a new packing unit. It sells 2,00,000 new shares at ₹150 each. Two lakh shares times ₹150 is ₹3,00,00,000, which is ₹3 crore. Many savers each buy a few shares, and together they supply the whole sum. No single saver has to give anything like ₹3 crore.

Money goes to the business, and ownership goes to the saver. The saver gets a part of the company, and the company gets money to grow. Both sides give something and receive something, which is why the arrangement can work for them. In the example, the saver gives rupees and receives shares, while the company gives shares and receives rupees. That exchange is the whole idea.

Some people think the market exists only for trading profits. Its first job is to move money to businesses. This does not tell you that every company can raise money this way, or that a raise will succeed. It only explains why the market exists. The trading of shares comes later and is a result of that first job.

A company becomes tradable on the market only after it is listed on an exchange. Listing is the step by which its shares start trading. Before it, the shares are held by a few people and cannot be bought by the public. After it, shares can trade on the exchange.

Think of a home-run tiffin business that opens a shop on the main road, with a licence. Now anyone can walk in. The picture stops working here. Listing is not a mark of quality. It is a legal step, and it brings duties to share information. A shop on the main road still has to earn its customers, and a listed company still has to earn the trust of its owners.

Before listing, Sabzi Wala Foods Ltd has 8,00,000 shares, all with the founders. It sells 2,00,000 new shares in an IPO, the first public sale of new shares, under SEBI rules. The IPO is the moment the company first asks the public for money. The public can then own part of the company for the first time.

After the IPO and listing, 8,00,000 plus 2,00,000 makes 10,00,000 shares. The public holds 2,00,000 of them, and they can now trade on the exchange. The founders still hold 8,00,000. The business is the same as before, with a wider group of owners. This is the same split of 80% and 20% that we saw in the section on shares.

Many people think a famous company is automatically listed. It may not be. This does not tell you whether a listed company is any good, because listing only shows that a legal step was completed. Quality has to be judged separately. A well-known name and a listed name are two different facts, and each has to be checked on its own.

In the primary market your money goes to the company. In the secondary market it goes to the seller. These are two moments in the life of a share. It matters to know in which of them you are buying, because only one of them pays the company.

Buying a new phone from the maker is the primary market. Buying a used phone from a neighbour is the secondary market. The picture stops working here. A used phone loses value, but a share's price can go either way. In both cases, the question to ask is the same: who receives my money, the maker or the neighbour?

In the IPO, buyers pay ₹150 per share for 2,00,000 new shares. The company receives 2,00,000 times ₹150, which is ₹3 crore. Later, Asha buys 10 shares at ₹200 from Ravi, another shareholder who is selling. She pays 10 times ₹200, which is ₹2,000. These are two different events on two different days.

The IPO price was ₹150. After listing, trading settled at ₹200, so we use ₹200 from here. Ravi receives the ₹2,000. Sabzi Wala Foods Ltd receives ₹0. Brokerage, charges and taxes are left out here and covered in a later lesson. The company already received its ₹3 crore at the IPO, and it takes no part in the later trade between Asha and Ravi.

The secondary market makes shares easy to buy and sell, meaning you can trade quickly without moving the price much. Buying on the exchange does not fund the company. This does not tell you that IPO shares will rise or are cheap. It only tells you who is paid.

A trade passes from you to a broker, to the exchange, to a clearing corporation, and into your demat account. SEBI sets the rules for all of them. Each step has one job, and a trade is complete only when every step has done its job.

Think of sending a courier parcel. A booking agent takes it, a hub sorts it, a guarantee covers delivery, and it reaches your door. The picture stops working here. These parts are separate firms with separate duties and fees. In the market, the booking agent is the broker, the hub is the exchange, the guarantee is the clearing corporation, and the door is your demat account.

Your order goes to a broker. The broker sends it to the exchange, which matches a buyer with a seller. The clearing corporation, such as NSE Clearing, stands between buyer and seller and guarantees the trade is completed. The two sides need not deal with each other directly.

Shares are held electronically in a demat account, which holds shares like a bank account holds money. A depository, NSDL or CDSL, keeps the records of who owns what. So the shares sit with a depository, in your name, and not with the broker. This is why the broker cannot simply keep your shares.

Follow Asha's trade. On Monday, her order for 10 shares at ₹200 matches Ravi's sell order. By Tuesday, the next working day, which is called T+1, the shares are in her demat account and ₹2,000 is with Ravi. The trade day is called T. Settlement means that the shares and the money finally change hands.

The price is the rate at which a willing buyer and a willing seller agree at that moment. Nobody sets it in advance. It is the result of many people making offers, and it changes whenever the balance between them changes. A price is therefore not a fixed label on a share. It is a record of the latest agreement.

Think of bargaining for tomatoes at a mandi, with many buyers and sellers at once. The picture stops working in one place. At a mandi a seller may call out a rate, but here no board sets it. The price moves with each agreement. If many buyers want the same tomatoes, the rate rises, and the same logic applies to shares.

Demand and supply means how many want to buy against how many want to sell. At ₹200, buyers want 600 shares of Sabzi Wala Foods Ltd. Sellers offer only 200. There are three times as many people wanting shares as people offering them. The mismatch cannot last at ₹200.

So 200 shares trade, and buyers for 400 shares are left waiting. Some of those buyers offer a higher price to get a share, and sellers then ask for more. The price moves up. Each new agreement is then made at the higher rate. More buyers than sellers pushes the price up.

A company does not decide its own share price. Buyers and sellers do. This does not tell you whether the price is right, because a price only records what people agreed to pay at that moment, and nothing more than that. The company can announce news, but the price that follows is set by the people trading.

Individuals, mutual funds and foreign investors all trade the same share, with different goals and sizes. They all meet at one price. The share is the same for each of them, and only the size of the buyer and the reason for buying differ. Whoever buys at that moment pays the same rate for one share.

Think of a mandi where homemakers, restaurant owners and big wholesalers bid for the same crate. The crate is the same for all of them. The picture stops working here. A big buyer can move the price more than a small one. A homemaker buys a few kilos, while a wholesaler may buy the whole crate and so be heard more loudly.

A mutual fund pools many people's money and invests it. Foreign investors, called FPIs, invest from abroad. Take the public part of Sabzi Wala Foods Ltd, which is 2,00,000 shares, and see how it might be held by these different groups. The numbers below are for teaching only.

Say a mutual fund holds 50,000 shares, which is 5% of the company. Foreign investors together hold 1,00,000 shares, which is 10%. Individuals, including Asha, hold the other 50,000. These add up: 50,000 plus 1,00,000 plus 50,000 is 2,00,000. Asha's own 10 shares are a tiny part of the individuals' 50,000, yet she is treated by the market in the same way as everyone else.

People often think big players always win. No one can say that in advance. This does not tell you who is buying or selling today. It only shows that many kinds of participants can hold the same share at the same time. A large holder can also be wrong, and its size is no promise of success.

Prices move when buyers and sellers change what they expect the company to earn. Expectations move first, and facts come later. A price is therefore a view about the future, and not only a record of the present. When the view changes, the price changes with it, even if nothing has yet happened inside the company.

Think of a rented flat. Its price rises when a metro station is announced nearby, before any train runs. People pay for what they expect. The picture stops working here. A flat's rent is fixed by contract, but share prices are re-set every moment. The same flat, with the same walls, becomes worth more only because people expect more from the area.

Say Sabzi Wala Foods Ltd reports profit higher than people expected. The price moves from ₹200 to ₹220. That is a gain of ₹20, and 20 divided by 200 is 10%. Market value is the price of one share times all shares, so 10,00,000 times ₹220 is ₹22 crore, up ₹2 crore.

Asha's 10 shares are now worth ₹2,200, up ₹200. Nothing changed in the factory that day, only expectations. Now say a big customer cancels. The price falls from ₹200 to ₹180, which is 10%. Market value is ₹18 crore, and Asha's shares are worth ₹1,800, down ₹200.

A good company does not mean a price that always rises, because the price already holds hopes. This does not tell you what happens tomorrow. It only explains why a price moves when news arrives, and why the move depends on what people had expected. If the news is merely as good as hoped, the price may not move at all.

If a business grows, the value of its shares can grow too, but that is never guaranteed. Time helps only when the business grows. A share is a part of the business, so the part can become more valuable only if the whole does. Waiting alone adds nothing.

Think of a fixed deposit and a plant. Both need time before you see a result. The picture stops working here. A deposit has a stated rate, but a share may not grow. A deposit is a promise made in advance by a bank, and a plant is a living thing that may or may not thrive. A share is closer to the plant, because it depends on how the business does, and nobody can promise that in advance.

This is teaching arithmetic only, not a forecast. Suppose the value grew 10% a year. Asha's ₹2,000 would become ₹2,000 times 1.10, which is ₹2,200 after year 1. The gain in year 1 is ₹200, which is 10% of ₹2,000. We use round numbers so that the sums are easy to check by hand.

In year 2, the 10% is on ₹2,200, giving ₹2,420. In year 3, it is on ₹2,420, giving ₹2,662. The total gain over the three years is ₹662, because each year's gain sits on a larger base than the one before it. The year 2 gain is ₹220 and the year 3 gain is ₹242, so each year adds a little more than the last.

Shares do not always grow over time. This does not tell you whether any company will grow 10% a year, or at all. The 10% here is only a number chosen to make the sums easy to follow, and it is neither a promise nor an estimate.

Every share can lose value. Risk is the chance that the result is worse than you expected, including losing money. Risk is not a rare event that happens only to others. It is part of owning any share, and it must be understood before any money goes in.

Some risks hit the whole market, and others hit one company. A failed monsoon hurts every farmer, while a broken pump hurts one farmer. The picture stops working here. Unlike weather, company risk can be reduced by spreading money. The first kind is called market risk, and the second is called company risk. They need different answers, because a farmer cannot avoid a failed monsoon by changing fields, but can reduce the damage from a broken pump by owning more than one pump.

Say Asha puts all ₹2,000 in Sabzi Wala Foods Ltd. If the company fails, she loses ₹2,000, which is 100%. Spreading means putting money in several companies, so that the failure of one does not take everything she has put in. This is the worst case for a single company, and it is worth keeping in mind.

If she puts ₹400 in each of 5 different companies, that is 5 times ₹400, or ₹2,000. If one fails, she loses ₹400, which is 20% of ₹2,000. The same ₹2,000 is exposed, but the failure of one company hurts much less. Spreading changes how the loss is shared, and it does not remove the chance of a loss.

Spreading does not mean no loss, because a market-wide fall still hits all five. It reduces company risk only, and not market risk. This does not tell you how much risk is right for you. That is for you and a registered adviser. Keep that limit in mind whenever someone suggests that spreading makes money safe.

An investor holds for the business over years. A trader aims at price moves over days or less. The difference is the time span, and what each one watches. The investor watches how the business is doing, while the trader watches how the price is moving. Neither word is better than the other. They describe two plans.

Think of buying a flat to rent out for years, and buying a flat to resell quickly. The picture stops working here. Both can lose money, and trading usually means more transactions and more charges. The first buyer waits for the rent and for the area to grow. The second buyer hopes to find a higher price within a short time. The plans differ, even though the flat is the same.

Asha buys 10 shares at ₹200 and decides to hold for three years. She watches the business, not the daily price. A fall on one day does not change her plan, because her plan was made for the business over years. She has decided her purpose before buying, which is the point of this section.

Ravi is a trader. On another day he buys 10 shares at ₹200 and sells them the same day at ₹201. His sale brings 10 times ₹201, which is ₹2,010, against ₹2,000 paid, before charges. His plan was about the price, within one day. The gap is ₹10, and charges would take a part of it, which is why trading usually means more charges.

A common mistake is to call a failed trade a long-term investment. The two are different plans, made before buying. This does not tell you which approach suits you. Both can lose money, so decide your purpose before you buy. Changing the name afterwards does not change what the plan was.

Most beginner fears and hopes about the market come from five myths. Each one sounds confident but is easy to check. Checking them one by one, with the example we have used, is better than accepting or rejecting them by feeling. Each myth is answered below using only what this lesson has already shown.

Think of advice at a tea stall: confident, but unchecked. People say it with certainty, and it spreads for that reason. Here are the first two myths, and what is true instead. The speaker may be sincere and still wrong, so the habit to build is to ask, how could I check this? The answers below show how each myth can be checked with what you have already learned about shares and prices.

Myth 1: it is a casino. In fact, a share is a part of a real company, with products, customers and staff behind it. Myth 2: the fastest clicker wins. In fact, speed is not skill, and a quick click is not a better idea. Both myths treat the market as a game of luck or reflexes, when it is a place where parts of businesses change hands.

Myth 3: a rising price means a good company. Sabzi Wala Foods Ltd rose 10% on expectations alone, from ₹200 to ₹220. Myth 4: a falling price means cheap. At ₹180, the price is lower, but not necessarily cheaper than the business is worth. In both cases the price tells you what people expect, and not what the business is.

Myth 5: the price is the truth. The price is the market's current opinion, and opinions change. This does not tell you what the business is worth. Check the idea, and not the confidence behind it. A price is one agreement between one buyer and one seller, and tomorrow's agreement may be different.

Before buying, know what you own, what you can lose, how long you can wait, and how the process works. Four short checks are enough. Each check connects to one part of this lesson, so you can use them as a quick list. Nothing on the list needs any special skill. It needs only that you have read the lesson.

Learning to swim starts in the shallow end. You learn the strokes first, in water where you can stand. The picture stops working here. Reading cannot replace practice, but practice should be small. A learner who jumps into deep water because the book was clear will still struggle, and so the sensible step is to start with small, careful practice and to leave the rest for later lessons.

First, what you own: a part of one company (section 2). Second, what you can lose: all of it (section 11). Third, how long you can wait: money needed soon should not sit in shares. Fourth, the steps: broker, exchange, clearing, demat (section 6). If you cannot answer any one of these four, you are not yet ready for the next step.

Here is one number worth knowing. Say ₹2,000 falls 50%, to ₹1,000. To get back to ₹2,000, the gain needed is ₹1,000, which is 100% of the ₹1,000 left. The gain is measured on the smaller amount, so in percentage it must be bigger. Many beginners expect a 50% gain to undo a 50% fall, and this simple sum shows why it does not.

So a 50% fall needs a 100% gain, and a big sum makes the fall cost more. This does not tell you how much to invest. That is not our role, and it is a personal decision that depends on your own situation. It only helps you see why losses deserve respect.

The stock market is a rule-based place where parts of companies are bought and sold at agreed prices. Everything in this lesson fits that one line. If you can explain it in your own words, you have understood the lesson. Try it once aloud, as if for a friend who has never bought a share.

Go back to the mandi picture. Add a shop, which is the company, and an inspector, which is SEBI. The picture stops working here. Goods are used up, but a share stays a part of the company. A buyer at the mandi takes the vegetables home and the deal ends. A buyer of a share stays an owner, and the deal continues for as long as the share is held, which is why the picture is only a help and not a full description.

Replay Sabzi Wala Foods Ltd in four steps. Its IPO raised ₹3 crore, and it listed 10,00,000 shares. Then Asha bought 10 at ₹200, which is ₹2,000. News then moved the price to ₹220 or ₹180. Each step matches one section of the lesson: raising money, trading, price and risk.

Value follows expectations, and grows only if the business grows. Four ideas are worth remembering: company, trade, price and risk. They answer what a beginner usually asks first: what is being sold, how it is sold, why the price moves and what can go wrong. Keep these four in mind as you read on.

A common mistake is to think, now I know enough to start. A lesson gives you the parts and the words. This does not tell you where to begin. The next lessons do that, and small steps are better than one big one. Treat this lesson as a map, and not as a licence to act.
