00 The Sixty-Second Answer

Every share you will ever own was sold twice: once by a company to raise money, and then again and again between investors.

The primary market is where a company sells new securities to investors for the very first time. Your money goes to the company. An IPO is the best-known example.

The secondary market is where those securities are bought and sold between investors, on exchanges such as the NSE and BSE. Your money goes to the investor who sold. The company is not a party to the trade and receives nothing.

Primary is the birth of a share. Secondary is the rest of its life.

When you tap “Apply” on an IPO, you are in the primary market. The moment that IPO lists and you tap “Buy” or “Sell” on a trading app, you are in the secondary market. The same share, the same company, two entirely different sets of rules, prices, risks and rewards.

The rest of this guide takes you through both doors slowly, with worked examples in rupees, so that you always know which market your next trade belongs to, who gets your money, and what can go right or wrong.

THE BIG PICTURE

I Two Doors, One Market

Imagine a bookshop and a second-hand bookstall on the same street.

A publisher prints a fresh batch of a novel and sells it through the bookshop. The publisher earns the money and uses it to print more books. This is the primary market: new supply, sold by the creator, money flowing to the creator.

A year later, you finish the novel and sell it to the second-hand bookstall, which sells it on to another reader. The publisher earns nothing from these later sales. But the fact that readers can resell is exactly what makes people comfortable buying the book in the first place. This is the secondary market: existing supply, passed between owners, money flowing between owners.

Capital markets work in precisely this way. Companies need long-term money to build factories, hire people and repay debt. Investors want to put money to work, but only if they can get out when they need to. The primary market connects companies to investors. The secondary market gives those investors an exit. Without the second, the first would barely function.

Why two markets exist at all

A company cannot call every shareholder each time someone wants to sell, and an investor will not lock money into a company for twenty years with no way out. So the system splits the job. One market creates securities and raises capital. The other circulates them and keeps them liquid. Together they form what economists call the capital market.

Who is in the room

– The company (issuer): raises money in the primary market, and is a silent bystander in the secondary market.

– SEBI: the Securities and Exchange Board of India. It writes the rules for how securities are issued and how they trade, and polices both.

– Merchant bankers and registrars: manage the IPO paperwork, pricing and allotment in the primary market.

– Stock exchanges (NSE and BSE): host the listing of shares and the daily trading of them.

– Brokers: your gateway into both markets. You need one to place IPO applications through your trading account and to buy or sell on the exchange.

– Depositories (NSDL and CDSL) and clearing corporations: hold your shares electronically in your demat account and make sure each trade settles properly.

– You: the investor, who can walk through either door, or both.

WHERE SHARES ARE BORN

II The Primary Market

In the primary market, the company is the seller, the price is set through a formal process, and the money goes into the company’s account.

When a business is ready to raise capital from the public, it issues new securities and sells them directly to investors. There is no exchange order book at this stage. Instead, there is an offer period, a price band or fixed price, a bidding window, and an allotment, all governed by SEBI’s Issue of Capital and Disclosure Requirements (ICDR) Regulations.

The main ways companies raise money

INITIAL PUBLIC OFFERING (IPO)

A private company sells shares to the public for the first time and gets listed on the stock exchanges. An IPO can be a fresh issue (new shares, money goes to the company), an offer for sale (existing shareholders sell, money goes to them), or a mix of both. Most investors meet the primary market here.

FOLLOW-ON PUBLIC OFFER (FPO)

A company that is already listed issues more shares to the public to raise additional capital. The word “follow-on” simply means it follows an earlier IPO.

RIGHTS ISSUE

A listed company offers new shares only to its existing shareholders, usually at a discount, in proportion to what they already hold. Example: Rao Textiles announces a 1-for-5 rights issue at ₹120 while its shares trade at ₹150. If you hold 500 shares, you can subscribe to 100 new shares for ₹12,000. Your rights entitlement can also be renounced, and entitlements are tradable on the exchanges during the rights window, so you are not forced to participate.

QUALIFIED INSTITUTIONAL PLACEMENT (QIP)

A listed company raises money quickly from qualified institutional buyers such as mutual funds, insurers and banks, without a full public offer. Ordinary retail investors cannot apply, but they feel the effect when new shares are issued and the share count rises.

PREFERENTIAL ALLOTMENT

New shares or warrants are issued to a select group, such as promoters or a strategic investor, at a price that must follow SEBI’s pricing formula, with shareholder approval.

OFFER FOR SALE (OFS): THE HYBRID

In an OFS, promoters of an eligible listed company sell part of their holding through a special window on the stock exchange. Because it uses the exchange platform, it looks like a secondary-market trade. Because it is a company-organised, one-time sale at a floor price with a portion reserved for retail investors, it is usually discussed alongside public issues. The key point: no new capital reaches the company. The promoter is the seller.

BEYOND EQUITY

The primary market is not only about shares. New mutual fund schemes launched through a New Fund Offer (NFO), company bonds and debentures, and government securities sold through RBI auctions are all primary issuances. Once they exist, they too can trade in the secondary market.

Fresh issue or offer for sale? Read this before you apply

A fresh issue grows the company’s capital: the cash enters the business and can fund expansion, debt repayment or working capital. An offer for sale hands money to existing shareholders such as promoters or early investors. Neither is automatically good or bad, but an issue that is almost entirely an offer for sale deserves a harder question: why are the people who know the company best choosing to sell?

How an IPO divides its shares

In a standard book-built mainboard IPO, shares are reserved for different kinds of buyers so that no single group crowds out the rest. The usual split is:

– Qualified Institutional Buyers (QIBs): up to 50% of the issue. Mutual funds, insurers, foreign portfolio investors and banks.

– Non-Institutional Investors (NIIs/HNIs): at least 15%. Individuals bidding above ₹2 lakh, along with corporates and trusts.

– Retail Individual Investors (RIIs): at least 35%. Individuals bidding for up to ₹2 lakh in total.

These proportions can vary for specific issue structures and are always confirmed in the offer document. A portion of the QIB category can also be set aside for anchor investors, large institutions that commit money a day before the issue opens. Their shares carry lock-in periods (half for 30 days, the rest for 90), which is meant to steady the share price after listing.

How retail investors actually apply

Retail applications are made through ASBA, “Application Supported by Blocked Amount”, almost always paid via UPI. When you apply, you approve a mandate in your UPI app and the amount is blocked in your bank account but not debited. Only if you receive an allotment is the money taken for those shares. If you do not, the block is released. UPI-based applications are permitted up to ₹5 lakh per application, while the retail category itself is capped at ₹2 lakh.

Remember also that SME IPOs, those on the SME platforms of NSE and BSE, follow tighter rules: the minimum application is typically two lots, around ₹2 lakh, and the “cut-off price” option is not available. They are higher-ticket, thinner-trading and carry greater risk.

A WORKED EXAMPLE

III A Worked IPO: Greenleaf Solar

Greenleaf Solar Ltd. is a fictional company. Its numbers are made up, but every rule used below is real.

THE OFFER

– Issue size: ₹1,000 crore, made up of a fresh issue of ₹800 crore and an offer for sale of ₹200 crore by early investors.

– Price band: ₹190 to ₹200 per share. Lot size: 75 shares.

– One lot at the upper band: 75 × ₹200 = ₹15,000. That is the smallest bid a retail investor can place.

– The retail ceiling: 13 lots × 75 shares × ₹200 = ₹1,95,000. A 14th lot would take the bid to ₹2,10,000, above the ₹2 lakh retail limit.

WHERE THE MONEY GOES

At ₹200 a share, ₹1,000 crore means about 5 crore shares. The ₹800 crore from the fresh issue goes into Greenleaf’s accounts to build a new manufacturing plant. The ₹200 crore from the offer for sale goes to the selling shareholders. Greenleaf receives none of it.

THE RETAIL SLICE AND THE LOTTERY

With 35% reserved for retail investors, about 1.75 crore shares, or roughly 2.33 lakh lots, are on offer to them. Suppose the retail portion is 30 times subscribed: investors have applied for about 30 times as many lots as exist.

When a retail category is oversubscribed, allotment is by draw of lots, so most applicants get nothing, and the winners usually receive one lot.

In that case, if you applied for one lot, your chance of allotment is roughly one in thirty. Applying for more lots does not raise your odds per application, because SEBI’s system gives each valid applicant a fair shot at a minimum lot first. And note that you can submit only one application per PAN in a category; duplicate applications are rejected.

THE TIMELINE, DAY BY DAY

Since December 2023, listing must happen within three working days of the issue closing. Here is how Greenleaf’s calendar looks if the issue closes on a Wednesday:

Mon – Wed Bidding window (three days)

Wed (T) Issue closes. UPI mandates must be approved before the deadline.

Thu (T+1) Basis of allotment is finalised and published by the registrar.

Fri (T+2) Shares credited to demat accounts; blocked money released for those who did not get shares.

Mon (T+3) Greenleaf lists on NSE and BSE. Secondary-market trading begins.

The weekend is not counted because T+3 means three working days. This compressed timeline replaced the older six-day cycle, which meant your money stayed locked up for much longer.

LISTING DAY: THE BRIDGE BETWEEN MARKETS

On listing day, a special pre-open session helps discover the opening price. Suppose Greenleaf opens at ₹236, an 18% premium to the issue price. Meera, who won one lot in the draw, paid ₹15,000 for 75 shares. At ₹236 her 75 shares are worth ₹17,700, a gross gain of ₹2,700.

If she sells on listing day, it is a short-term capital gain on listed equity, taxed at 20% under the rates in force at the time of writing, about ₹540 here. Add transaction tax and exchange charges of a few tens of rupees and she is left with roughly ₹2,100. Real, but modest. Had Greenleaf instead listed at ₹175, she would have held a ₹1,875 loss on paper. Listing gains are never guaranteed.

WHERE SHARES CHANGE HANDS

IV The Secondary Market

Once a share is listed, the company steps aside and investors take over. Prices now move every second.

The secondary market is the stock exchange you see on the news. When you buy a listed share, you are not buying it from the company. You are buying it from another investor who has chosen to sell, and the exchange matches the two of you anonymously. Every trade is a transfer of ownership, and the sale price goes to the seller.

How a trade really happens

01 You place an order through your broker’s app: a share, a quantity, and either a price (a limit order) or “at whatever the best price is now” (a market order).

02 The order reaches the exchange, NSE or BSE, and joins the order book, a live list of everyone’s buy and sell orders.

03 Matching. The exchange pairs the highest buy price with the lowest sell price, and when two orders at the same price compete, the one placed earlier goes first. If your bid meets someone’s ask, you have a trade.

04 Clearing. A clearing corporation steps between buyer and seller, guaranteeing the trade and calculating what each side owes.

05 Settlement. On the next working day (T+1), money moves from the buyer’s account and shares move into the buyer’s demat account via the depository.

The whole matching step takes a fraction of a second, but the legal and financial settlement is what makes the trade real.

Settlement: T+1, and the arrival of T+0

India completed its move to T+1 settlement on 27 January 2023, which means a share bought on Monday is settled on Tuesday, down from two days earlier. A same-day T+0 option has also been introduced on a voluntary basis for a limited set of stocks since March 2024, running alongside T+1 rather than replacing it. For almost every ordinary investor, T+1 is the rule to know.

Rhythm of the trading day

– Pre-open session (about 9:00 to 9:15 am): orders are collected and an opening price is determined.

– Normal trading (9:15 am to 3:30 pm): continuous matching of buyers and sellers.

– Price bands and circuit limits: most stocks have a daily band (such as 5%, 10% or 20%) beyond which trading in that stock pauses or stops, to contain extreme swings.

What drives the price

Unlike the primary market, where a price band is proposed and then bids reveal demand, the secondary market is a continuous auction. Prices rise when more people want to buy than sell, and fall when it’s the opposite. Company results, interest rates, global cues, sector news and sheer sentiment all push on that balance every minute. This ongoing process is called price discovery.

Liquidity: the secondary market’s great gift

Liquidity means how easily you can buy or sell without moving the price. Heavily traded large companies have narrow bid-ask spreads, the small gap between the best buy and best sell price, and trades go through at nearly the quoted price. Thinly traded stocks have wide spreads and higher impact cost: a large order can nudge the price against you. This is why SME stocks, with fewer buyers and sellers, call for extra caution.

What it actually costs to trade

Brokerage depends on your broker and the type of trade, and some brokers charge nothing on delivery. But statutory costs apply no matter whom you trade with. On equity delivery trades, Securities Transaction Tax (STT) is 0.1% on both the buy and the sell side, with exchange transaction charges, SEBI turnover fees, GST on applicable charges, and stamp duty on the buy side as well. Example: buying 100 shares at ₹1,450 is a ₹1,45,000 trade, and STT alone is about ₹145.

What you owe in tax

Profits on listed equity are taxed as capital gains. At the rates in force at the time of writing, shares sold within 12 months attract short-term capital gains tax of 20%, while shares held longer attract long-term capital gains tax of 12.5% on gains above ₹1.25 lakh in a financial year. Tax rules change, so check the latest rates, or ask a tax professional, before you act.

Delivery, intraday and derivatives

Inside the secondary market there are distinct styles. Delivery means you buy and hold shares in your demat account. Intraday means you buy and sell the same stock within one day with no delivery. Derivatives (futures and options) are contracts whose value is derived from an underlying asset and carry much higher risk. This guide concerns the ownership of shares, but all of these live in the secondary market.

A STORY IN TWO ACTS

V One Share, Two Markets

Let’s follow a single Greenleaf share, and the two people who held it.

ACT ONE: THE PRIMARY MARKET

Meera, a software engineer in Bengaluru, applies for one lot of Greenleaf’s IPO at ₹200. Her UPI mandate blocks ₹15,000. She wins the draw. ₹15,000 leaves her account, and flows to Greenleaf and the selling shareholders. Seventy-five shares land in her demat account. Meera is now a shareholder.

ACT TWO: THE SECONDARY MARKET

On listing day, Meera decides to book her profit. She places a limit order to sell at ₹236. Raj, an investor in Pune, has a buy order at ₹236 sitting in the order book. The exchange matches them. Neither knows the other exists.

Raj pays ₹17,700. That money goes to Meera, not to Greenleaf. Next working day, the shares move from Meera’s demat account to Raj’s. Greenleaf’s balance sheet does not change by a single rupee.

A year later, Greenleaf trades at ₹310. Raj sells. His gain per share is ₹74, or ₹5,550 over 75 shares. Because he held for more than 12 months and his total long-term gains for the year are below the ₹1.25 lakh exemption, he may owe no capital gains tax on this sale. Greenleaf, again, receives nothing.

One share. Two markets. Two completely different answers to the question: who gets my money?

What the story teaches

– The primary market funds the company. The secondary market only reassigns ownership.

– Meera could only afford to take IPO risk because she knew she could exit quickly in the secondary market.

– A strong secondary market makes future primary issues cheaper and easier for the company to sell. A weak one makes investors hesitate.

– The price at listing is determined by the secondary market’s demand and supply, not by the company or its merchant banker.

THE COMPARISON

VI Side by Side

Fourteen differences, one at a time.

Notice how almost every row follows from the first one. Because the primary market exists to raise money, it needs rules about disclosure and allotment. Because the secondary market exists to circulate securities, it needs rules about matching, clearing and surveillance.

CLEARING THE AIR

VII Seven Myths, Seven Facts

MYTH  “Every IPO gives listing gains.”

FACT  Listings can open above, at or below the issue price. Many IPOs have listed at a discount. The offer price reflects the issuer’s valuation, not a guarantee.

MYTH  “IPO shares are cheaper than market shares.”

FACT  An IPO share is priced by the company and its bankers, often at a premium valuation to peers. It is not a discount product.

MYTH  “If I buy a stock on the exchange, I am funding the company.”

FACT  No. Your money goes to the seller. The company only receives funds in the primary market.

MYTH  “The primary market is for big investors only.”

FACT  Retail investors have a dedicated reservation of at least 35% in most IPOs, and can apply from about ₹15,000 for one lot.

MYTH  “Grey market premium tells me what the listing price will be.”

FACT  The grey market is unofficial, unregulated and unreliable. It is not a substitute for reading the offer document.

MYTH  “An OFS brings fresh money to the company.”

FACT  An OFS is a sale of existing shares by shareholders. The company does not receive the proceeds.

MYTH  “The secondary market is just gambling.”

FACT  It can be used for speculation, but it is also how long-term investors build wealth in real businesses, using research, patience and diversification.

PUTTING IT TO USE

VIII Choosing Your Door

The better question is not which market is superior. It is which one fits the decision in front of you.

The IPO checklist

Before you apply, read the offer document, the Red Herring Prospectus (RHP), or at the very least its summary, and ask:

– What will the money be used for? Look for growth, debt reduction or capacity. Be wary of vague “general corporate purposes” as the main use.

– How much is fresh issue and how much is OFS? A large OFS means big sellers are exiting.

– Is the valuation reasonable against listed peers? Compare price-to-earnings and other ratios with similar companies.

– How strong and consistent are the financials? Revenue, profit, debt, cash flow and how they have trended.

– Who are the promoters, and what is their track record? Check for pending litigation and related-party dealings.

– What are the risk factors? The document lists them by law. Read them honestly.

The secondary market checklist

– Do I understand the business well enough to explain it in two sentences?

– Is the stock liquid enough to exit when I want, at a fair price?

– What is my time horizon? Delivery investing over years differs wildly from intraday trading.

– Have I diversified? Concentration in one stock or sector multiplies risk.

– Do I know my total costs and tax? STT, charges and capital gains eat into every return.

Mistakes that cost real money

– Applying for an IPO only because of social-media hype or grey-market chatter.

– Forgetting to approve the UPI mandate before the closing-day deadline, so the application never counts.

– Submitting multiple applications on one PAN in the same category, which can get them rejected.

– Putting all IPO hopes on one application instead of treating allotment as a lottery you may not win.

– Chasing a listing-day spike without a plan for when to sell.

– Trading a stock without checking its liquidity, then being unable to exit.

Your safeguards

SEBI regulates both markets. Issuers must file detailed disclosure documents, exchanges monitor trading for manipulation, depositories hold your shares in your name electronically, and clearing corporations guarantee settlement. If something goes wrong, you can file a complaint through the SEBI SCORES grievance platform. These protections reduce certain risks, but they cannot protect you from a bad investment decision or a falling share price.

STRAIGHT ANSWERS

X Questions Investors Ask

Do I need a demat account for both markets?

Yes. Shares in India are held electronically, so you need a demat account (with a trading account linked to it) to receive IPO allotments and to buy or sell on the exchange.

Can I sell IPO shares on the day they list?

Yes. Once the shares list and trading begins, allotted shares in your demat account can be sold like any other listed share, subject to any lock-in that applies to your category. Retail IPO allottees generally have no lock-in.

Is an IPO safer than buying listed shares?

No. An IPO is a first-time price discovery with limited trading history. Listed shares have a public track record and live pricing, though they too carry market risk.

What is the difference between IPO and FPO?

An IPO is the first time a company offers shares to the public. An FPO is a later offer by a company that is already listed.

Can I buy shares before they are listed?

Some unlisted shares change hands in informal or unlisted markets, but these lack the exchange’s transparency, price visibility and settlement safeguards. Prices can be opaque and disputes harder to resolve. Treat them with great care.

What is a lot, and why does it matter?

A lot is the minimum bundle of shares you must bid for in an IPO. Your application must be in multiples of that lot. Lot size is set so that the minimum retail investment is around ₹15,000.

What is the cut-off price option?

Retail investors in mainboard IPOs may bid at the “cut-off price”, which means they agree to pay whatever final price is fixed within the band, up to the upper end. This improves the chance that the bid is valid. It is not available in SME IPOs.

If I am not allotted shares, do I lose interest on my money?

No. With ASBA the money stays in your own bank account throughout, only blocked, and is released after the allotment is finalised. Your balance continues to be yours.

Which market has more liquidity?

The secondary market. Liquidity is precisely what it provides. The primary market has no ongoing liquidity until the shares list.

Can I participate in both?

Of course. Many investors apply for selected IPOs and also build long-term holdings by buying listed shares. The two approaches complement each other, as long as you apply the right checks to each.

IN CLOSING

XI Where to Go From Here

If you remember one sentence from this guide, make it this one.

The primary market decides who the company’s first shareholders are. The secondary market decides what every later shareholder pays.

Knowing which door you are standing in front of changes how you read the price, how you judge the risk, how you plan your exit, and how you think about what your money is actually doing. Primary investors are placing a bet on a company’s story at a price someone else has set. Secondary investors are continuously negotiating that price with the whole market.

Neither door is the “right” one. Both are legitimate, both carry risk, and both reward preparation. Read the documents, understand the costs, respect the lottery, and never invest more than you can afford to see fall.
