The primary market is the part of the capital market in which new securities are issued and sold for the first time. When a company sells newly created shares or a government sells new bonds, the buyers pay the issuer directly, usually through banks acting as intermediaries, and the money goes to fund the issuer's projects, refinance its debt or cover its spending. The best-known primary-market event is an initial public offering, but most primary-market money is raised by repeat issuers such as governments and large companies.
The primary market is paired with the secondary market, where investors later trade those same securities among themselves without the issuer receiving anything. The two depend on each other: investors pay more for new securities when they know they can sell them easily afterwards. Both form part of the wider capital market, which channels savings into long-term investment.
Primary market in plain terms
Think of buying a new car straight from the factory showroom compared with buying a used car from a neighbour. When you buy from the showroom, your money goes to the carmaker, which can use it to build more cars. When you later sell the car to someone else, the carmaker gets nothing; the money just passes between drivers.
The primary market is the showroom. It is where companies and governments turn investors' savings into fresh money for factories, roads, hospitals or paying old bills. Everything that happens to the security after that first sale belongs to the second-hand market.
Ways of issuing
- Initial public offering. A private company sells shares to the public for the first time and becomes a listed company, a process also called a flotation.
- Follow-on or secondary offering. An already listed company sells more shares, which dilutes existing owners unless they buy their share.
- Rights issue. Existing shareholders are offered new shares in proportion to their holdings, usually at a discount, so they can protect their stake.
- Private placement. Securities are sold to a small group of institutional investors rather than the general public, with lighter disclosure.
- Bond issuance. Companies sell a corporate bond, and governments sell government bonds and Treasury securities, often by auction to a network of primary dealers. International borrowers may issue a Eurobond.
For most share offerings, one or more investment banks act as underwriters. Through bookbuilding, they collect indications of demand from investors at different prices and then set a final offer price. In firm-commitment underwriting the banks buy the shares and resell them, taking the risk that demand falls short. Many offerings also include an over-allotment or "greenshoe" option that lets underwriters sell extra shares to stabilize the price after trading begins. Some issuers have used auctions instead, as Google did for its 2004 IPO, or skipped new money altogether with a direct listing.
A rights issue changes the share price in a predictable way. The theoretical price after the issue is:
- TERP is the theoretical ex-rights price.
- is the number of existing shares and their market price before the issue.
- is the number of new shares and the subscription price.
For example, a one-for-four rights issue at $8 when shares trade at $10 gives . A shareholder who takes up the rights ends with five shares worth $48 in total, the same as the $40 of old shares plus the $8 paid in.
Regulation and disclosure
Because buyers of new securities rely on the issuer's own description of itself, primary markets are heavily regulated. In the United States, the Securities Act of 1933 requires public offerings to be registered with the SEC through a prospectus, with exemptions such as Regulation D for private placements. The EU Prospectus Regulation sets common disclosure rules across member states, and in Pakistan the Securities and Exchange Commission of Pakistan approves prospectuses for offerings on the Pakistan Stock Exchange. Issuers are liable for misleading statements, and analysts at the underwriting banks are restricted during the offering period.
Primary markets and the economy
Primary issuance is how savings become investment in plant, equipment and research. Equity issuance tends to rise in bull markets, when high prices make selling shares cheap, and to dry up in downturns; debt issuance is driven more by interest rates and credit conditions. In practice, established companies in many advanced economies fund most investment from retained profits and borrowing, and in some years they buy back more shares than they issue. Governments are the largest single issuers, and their auctions set benchmark yields that price the rest of the market, from mortgages to the risk-free rate used in valuation.
Critics point to recurring problems in IPO markets, such as deliberate underpricing that favours banks' preferred clients, hype around fashionable sectors, and poor long-run returns for some new issues. Supporters reply that underpricing compensates investors for the uncertainty of buying an untested company, and that open primary markets give firms an alternative to bank loans, venture capital and private equity.
