Chapter 6: Securities Market Segments

Primary Market · Secondary Market · Corporate Actions

6.1 Nature and Definition of Primary Markets

The primary market ("new issue market") is where companies raise equity or debt funds from outside investors (those not associated with promoters) through an offer of securities — also called "going public". In the primary market, investors purchase securities directly from the issuer.

6.1.1 Functions of the Primary Market

Wider Markets & Investors

Enables participation of a wider investor group at competitive terms, moving away from restrictive funding sources.

Transparent Pricing

Price set by demand-supply & perceived fundamentals. G-secs priced via auction; equity via book-building.

Ownership Diversification

New subscribers reduce existing shareholders' stakes, broad-basing ownership and separating ownership from management.

Better Disclosures

Higher disclosure/transparency standards prescribed by regulation for new investors.

Evaluation by Investors

Adds a layer of scrutiny beyond auditors/regulators — analysts, media, activists.

Exit for Early Investors

Promoters/early investors can profit by selling holdings via the primary market issue.

Liquidity for Securities

Distributes securities to many investors; mandatory listing opens up secondary market trading.

Regulatory Supervision

Comprehensive SEBI/Companies Act oversight of the entire issuance process protects investor interests.

6.1.2 Types of Issues

TypeDescription
Public IssueIPO or FPO — open to the public
Private PlacementWholesale issue to a select set of (often institutional) investors by an unlisted company
Preferential IssueListed issuer offers securities to select persons/group on a private placement basis (excludes ESOPs/ESPS/sweat equity/foreign DRs)
Qualified Institutions Placement (QIP)Listed issuer issues to Qualified Institutional Buyers (mutual funds, FPIs, insurance cos.) on private placement basis
Rights & Bonus IssuesOffered to existing investors as on a cut-off date — rights (buy more at a price) or bonus (free additional allotment)

6.1.3 Types of Issuers

IssuerNotes
Central/State/Local GovernmentsG-Secs — T-Bills (<1 yr; only Centre issues) and bonds/dated securities (Centre & States as SGSs); risk-free "gilt-edged"
Public Sector Units (PSUs)Government-majority companies; share sale by govt. = "disinvestment" (e.g., Power Grid Corp, Dec 2013: 13% fresh equity + 4% govt. stake sale); also issue tax-free bonds (e.g., NHAI, Jan 2014)
Private Sector CompaniesIssue equity, preference shares, convertibles, corporate bonds (long-term) and commercial paper (short-term, <1 yr)
Banks, FIs & NBFCsEquity, preference shares, bonds, convertible bonds, CP, CDs, securitized paper
Mutual FundsNew Fund Offer (NFO) — closed-end (fixed period, then returns value) or open-end (perpetual, exit anytime)
REITs & InvITsIssue units publicly/privately; REIT → real estate, InvIT → infrastructure; listed; higher minimum investment than normal IPO
Alternative Investment FundsPrivately pooled via private placement only; cannot invite the public; may also raise debt
Types of Investors in Primary Issues: Resident individuals, HUFs, minors (via guardians), registered societies/clubs, NRIs, PIOs, banks, FIs, association of persons, companies, partnership firms, trusts, FPIs, LLPs.

6.1.5 Types of Public Issue of Equity Shares

Initial Public Offer (IPO)

First public offer of shares by a company. May be:

  • Fresh Issue: new shares issued; share capital increases; existing holders' % stake falls; proceeds go to company
  • Offer for Sale (OFS): existing holders (promoters/FIs) sell part of their holding; share capital unchanged; proceeds go to selling shareholders, not the company (e.g., government PSU disinvestment)
  • Or a combination of both

Further Public Offer (FPO)

Made by an issuer that has already done an IPO — a follow-on issue for growth capital or to retire debt/redo capital structure; may also be via OFS, e.g., to meet minimum public shareholding norms or when promoter lock-in ends.

6.1.6 Pricing a Public Issue of Shares

Fixed Price Issue

Company + lead manager (merchant banker) decide and disclose the issue price upfront, justified against expected performance and comparable companies' share prices.

Book Built Issue

Floor price or price band (band can be up to 20% above floor) is announced; investors bid price & quantity; retail investors can revise bids; the cut-off price is the price at which the issue gets fully subscribed — all bidders at or above cut-off get allotment.

Worked Example: Book-Building & Cut-off Price

A company issues 5,000 shares within a price band of Rs.120–Rs.144:

Price (Rs)No. of SharesCumulative Demand
1441,000 (A)1,000
1401,500 (B)2,500 (A+B)
1352,500 (C)5,000 (A+B+C)
1301,000 (D)6,000 (A+B+C+D)
120500 (E)6,500 (A+B+C+D+E)

The 5,000-share offer gets fully subscribed at the cut-off price of Rs.135 — all bidders at Rs.135 and above get allotment. (Retail investors may get a discount of up to 10% below the cut-off price under certain issues.)

6.1.7 – 6.1.10 Regulatory Norms, Application, Debt Issues, and Rights Offers

Regulatory Norms & Prospectus

Governed by SEBI ICDR Regulations 2018 & Companies Act 2013/1956 (also RBI norms for non-resident issues). Issuer files a prospectus (draft → SEBI comments → final filed with RoC, SEBI, exchange) detailing operations, finances, promoters, fund-use and pricing.

Applying via ASBA / UPI

ASBA (Application Supported by Blocked Amount): authorizes the bank to block application money, releasing funds only on allotment. SEBI also enabled UPI-based blocking for retail applications. In book-built issues, minimum application value must fall in the SEBI-prescribed range of Rs.10,000–Rs.15,000; investors may bid at the cut-off to ensure acceptance.

Over/Under-subscription

Over-subscribed: bids exceed shares offered → proportionate allotment + refund of excess. Under-subscribed: all qualifying applicants get full allotment. Shares credited to demat accounts; refunds issued for partial/non-allotment.

Public Issue of Debt & Rights Offer

Debt issues require a lead manager, offer document filed with SEBI/RoC, mandatory listing, and at least one credit rating (all ratings disclosed if multiple); debenture trustees (banks/FIs registered with SEBI) protect investor interests, ensuring adequacy of security cover. Rights offers (Rights Entitlements/REs) carry their own ISIN, are tradeable on exchanges, and applications must be via ASBA.

6.2 Role and Function of the Secondary Market

The secondary market is where already-issued securities are bought/sold between investors — transactions don't bring fresh capital to the issuer (funds only move between investors). It supports the primary market by providing liquidity, price discovery, information signalling and acting as an economic barometer.

FunctionExplanation
LiquidityInvestors can exit/enter listed securities easily and at low cost — enables investing in perpetual/long-term instruments without funds getting "blocked"
Price DiscoveryBuy/sell transactions reflect collective investor assessment of fundamental worth; rising demand → price rises (signal of good prospects) and vice versa. Example: A Rs.10 face-value share trading near Rs.100 may guide pricing of a fresh issue near Rs.100.
Information SignallingMarket prices instantly reflect available information (efficient markets), pressuring issuers to perform
Indicating Economic ActivityIndices (Sensex, Nifty 50) act as a barometer — sustained rises signal healthy growth, declines signal weakening activity
Medium for Corporate ControlUnderperformance → undervaluation → takeover threat → pressure for better governance (even potential takeover possibility disciplines management)

6.2.3 Market Information

Market Capitalisation

Market Cap = Shares Outstanding × Market Price per Share

  • Blue-chip / large-cap: largest companies, highly liquid
  • Mid-cap: medium-sized, good liquidity
  • Small-cap: smaller, less liquid

Market-cap-to-GDP ratio indicates the size/importance of a country's stock market.

Market Turnover

Indicates trading activity (in rupees or number of trades) on a given day. Higher turnover = better liquidity.

Turnover Ratio = Turnover (Rs) ÷ Market Capitalisation

Market Indices

An index tracks market movement using prices of a representative basket of (typically liquid, market-cap-weighted) shares. India's most widely tracked: S&P BSE Sensex and NSE Nifty 50. Sector indices (banking, IT, pharma, FMCG) also exist. Uses: real-time tracking, leading indicator of economic/sector performance, performance benchmark for funds.

6.2.4 Risk Management Systems in the Secondary Markets

High trade volumes increase liquidity but also systemic risk — a member's default can have catastrophic effects. Exchanges set up risk-containment systems for two functions: high-liquidity execution and guaranteed settlement.

MechanismDescription
Capital Adequacy NormsMembers maintain minimum paid-up capital/net worth: Base Minimum Capital (BMC, no exposure allowed against it) + Additional/Optional Capital (covers margin requirements)
MarginsUpfront % of dues paid by buyers/sellers when placing orders, to cover non-payment/non-delivery risk; brokers collect from clients, exchanges collect from brokers
Circuit Breakers & Price BandsIndex-based market-wide circuit breakers at 10%, 15%, 20% moves (either direction, triggered by Sensex or Nifty 50, whichever breaches first) halt trading market-wide. Daily price bands on individual securities: 2%, 5%, 10% or 20% (depending on whether derivatives are available on the scrip)
Settlement Guarantee MechanismClearing corporation becomes counterparty to every trade (novation), eliminating counterparty risk and guaranteeing settlement even if a member defaults; backed by the Core Settlement Guarantee Fund (Core SGF)
On-line MonitoringReal-time surveillance of positions/transactions; alerts on abnormal build-ups or inadequate margins; investigation of unusual price/volume moves
Price Monitoring & ActionSpecial margins on volatile scrips, reduced circuit filter limits, shifting scrips to trade-to-trade segment (forces delivery, reduces intraday volatility)
Inspection of BooksAnnual inspection of trading members for compliance; violations attract disciplinary action

Worked Example: Margin Requirement

An investor buys 100 shares of Company X at Rs.100 each on 1 Jan 2020 (total Rs.10,000, payable by 3 Jan 2020). To minimize default risk, both the buyer and seller must pay a percentage of dues upfront as margin. If the margin is set at 17%, the buyer pays Rs.1,700 in advance (17% × Rs.10,000).

6.3 Corporate Actions

Corporate actions have direct implications for shareholders — sharing surplus (dividend, bonus), changes in capital structure (rights, buybacks), M&A, delisting. All are regulated by the Companies Act 2013, SEBI regulations and listing agreements; require notice to regulators. The record date / book closure period determines which shareholders (in physical or demat form) are eligible to receive the benefit.

Corporate ActionKey Features
Rights IssueOffer of fresh shares to existing shareholders in a fixed ratio (e.g., 1:1, 1:2, 2:3) to prevent dilution of their proportionate holding; needs record date, letter of offer (filed in draft with SEBI); rights entitlements (REs) credited to demat accounts
Bonus IssueFree additional shares to existing holders in a ratio (e.g., 1:3 = 1 bonus share per 3 held), funded from genuine free reserves; barred if company has defaulted on debt/FD interest or principal; needs board (and sometimes shareholder) approval
DividendShare of company profits distributed to shareholders — interim (during the year) or final (year-end); payable only out of current/P&L profits; loss-making companies, those that defaulted on preference share redemption, or used share premium/revaluation/capital redemption reserves cannot declare dividends; SEBI mandates per-share basis disclosure
Stock SplitReduces face value in a defined ratio (e.g., 1:5 splits 1 share into 5; face value becomes 1/5th); number of shares rises proportionately; total value of holding and company's share capital remain unchanged; improves liquidity for high-priced shares
Share BuybackCompany repurchases its own listed shares from reserves/surplus; bought-back shares are extinguished, reducing share capital; boosts EPS and supports share price; eligibility requires no default on interest/principal/FD/preference redemption/dividend/term-loan interest
DelistingPermanent removal from exchange listing — compulsory (regulatory/listing-agreement non-compliance) or voluntary (company buys back shares via reverse book-building)
Mergers & AcquisitionsSubstantial acquisition of shares/voting rights changes shareholding pattern; SEBI Regulations give public shareholders an exit opportunity (open offer)
Offer for Sale (OFS)Existing investors sell shares to the public; no new shares issued; proceeds go to the selling investor, not the company; lets anchor investors exit partially/fully

Worked Example: Dilution & Rights Issue

A company has 10 lakh shares of Rs.10 each = Rs.1 crore issued/paid-up capital. If it issues another 10 lakh shares, existing shareholders' proportionate holding falls by half (capital doubles) — called dilution. To protect them, the Companies Act requires a rights issue first. A 1-for-1 rights issue means each shareholder gets 1 new share for every 1 held — capital doubles but proportionate holdings stay the same.

Worked Example: Stock Split

An investor holds 100 shares of face value Rs.10, trading at Rs.1,000 each (holding value = Rs.1,00,000). After a 1:5 split: 500 shares of face value Rs.2 each, trading near Rs.200 (500 × Rs.200 = Rs.1,00,000). The total value of the holding is unchanged; only the number of units and price per unit change (actual market price will depend on demand-supply).

Worked Example: Bonus Issue

A bonus issue in the ratio 1:3 entitles a shareholder to 1 free bonus share for every 3 shares already held — funded purely out of free reserves built from genuine profits, with no consideration from the shareholder.

Key Takeaways

  • Primary market = new issuance ("going public"); functions include wider market access, transparent pricing, ownership diversification, better disclosures, exit for early investors, liquidity and regulatory supervision.
  • Issues can be Public (IPO/FPO), Private Placement, Preferential, QIP, or Rights/Bonus; pricing can be Fixed Price or Book Built (cut-off price mechanism).
  • ASBA/UPI is mandatory for public issue and rights issue applications; minimum bid value Rs.10,000–15,000.
  • Secondary market provides liquidity, price discovery, information signalling, economic indication and acts as a medium for corporate control — without raising fresh capital for the issuer.
  • Risk management: capital adequacy (BMC), margins, circuit breakers (10/15/20%), price bands, novation via clearing corporation + Core SGF, online surveillance.
  • Corporate actions — rights, bonus, dividend, stock split, buyback, delisting, M&A, OFS — each has distinct mechanics, eligibility conditions and shareholder impact, all anchored to a record date.
