The market is often used to gauge the health of an economy. But that’s only the prologue to the story of markets in finance.
Fundamentally, a financial market is where investors can purchase products, such as stocks, by entering into contracts at a certain price. In its simplest form, a profit is made when buyers purchase low and sell high.
But where exactly should investors allocate their funds? Understanding the intricacies of the primary and secondary markets can help investors fully grasp the market and how it functions.
Those who have tracked recent initial public offerings (IPOs) of splashy companies like Instacart and Robinhood are familiar with the primary market. It’s where new securities can be purchased directly from an issuer.
In addition to IPOs, primary market transactions include rights offerings to current shareholders, non-public offerings to pre-selected investors, and preferential allotment.
The primary market helps businesses grow and finance new projects while allowing investors to buy securities at the issue price. However, investment in this market is generally limited to corporations, financial institutions, and accredited investors.
The secondary market, on the other hand, is more accessible to the general public. Investors can buy and sell securities that have already been issued, such as stocks or bonds.
National exchanges like Nasdaq and the New York Stock Exchange are part of the secondary market, which supplies liquidity to the economy. Unlike the primary market, transactions take place between investors with no direct involvement from the issuer.
This opens up the market to a wider audience while allowing shareholders in private companies to cash in on equity holdings through the private stock market.
The purpose of the primary market is to raise capital for issuers, whether companies or the government. The secondary market, on the other hand, provides liquidity and enables price discovery for investors.
Investment instruments vary between the two. While primary markets rely mostly on IPOs, the secondary market features many options, from stocks and bonds to exchange-traded funds, currencies, and real estate investment trusts (REITs).
To dive deeper into how these financial markets operate, it's helpful to look at how each market is subdivided, how transactions occur, and who regulates and participates in them.
Within the secondary market, different mechanisms dictate how securities are traded:
In an auction market, buyers and sellers publicly declare the prices at which they’re willing to transact. These bids and asks are matched efficiently through open competition. The New York Stock Exchange (NYSE) is the most well-known example of an auction market, where prices are determined through direct interaction on the trading floor or its digital counterpart.
Unlike auction markets, dealer markets don’t require a central exchange. Instead, dealers (market makers) maintain inventories of securities and are ready to buy or sell directly with investors. Prices are determined by the dealer and profits come from the bid-ask spread. Nasdaq operates as a dealer market.
OTC markets allow the trading of securities not listed on formal exchanges. These typically include smaller companies, penny stocks, or certain fixed-income instruments. OTC markets are decentralized and can offer niche investment opportunities, but often come with higher risk due to limited regulatory oversight and transparency.
Both market types offer unique advantages and challenges for different investor profiles and goals.
Regulatory frameworks and participant roles differ significantly across primary and secondary markets.
In the U.S., oversight is shared among several key institutions:
Trading platforms: Include major exchanges like NYSE, Nasdaq, and alternative trading systems (ATS)
Beyond the public secondary market, pioneering platforms like Augment are increasingly improving access to private investments. With Augment, investors can buy and sell existing stakes in private companies or funds before a traditional exit event, such as an IPO or acquisition.
Though these private secondary markets are open only to accredited and institutional investors, they create opportunities for a wider pool of players, effectively lowering the risk profile of each investment as a result.
Augment demonstrates the secondary market’s ability to facilitate price discovery and grow opportunities for diversification and risk management in investment portfolios. And with enhanced transparency, Augment makes the research and purchasing process easily accessible and actionable.
The financial system is a vast network with opportunities to buy and sell stakes in companies across the market. Both primary and secondary markets play a critical role in ensuring the system remains competitive and fair. Understanding how both play into the bigger picture can help investors make informed investment decisions.
Investing in private securities involves significant risks including potential loss of principal, limited liquidity, and no guaranteed returns. These investments are available only to qualified accredited investors and typically have longer holding periods with limited pricing transparency. Historical performance does not predict future results.
