The capital market is an environment where companies and investors come together to move financial resources in a structured and secure way. It offers opportunities both for those looking to make their money grow and for businesses that need capital to expand.
Understanding how this market works is essential for making informed decisions, whether to invest more safely or to understand how large companies finance themselves and create jobs.
Throughout this article, we will explore everything you need to know about the capital market, so that you feel more confident taking your first steps or deepening your knowledge of this universe.
What is the capital market?
First of all, it is important to understand what the capital market is. Simply put, it is an environment where companies can raise funds to finance their projects and expand their operations, while investors find opportunities to put their money to work and earn financial returns.
This market facilitates the buying and selling of securities, such as shares and debentures, connecting those who have money to invest with those who need resources to grow.
Unlike the financial market in general, which includes short-term operations such as bank loans, financing and investments in products like savings accounts and CDBs (bank certificates of deposit), the capital market focuses on medium- and long-term investments.
While the financial market is more geared toward liquidity and credit management, the capital market focuses on developing companies and growing the economy through structured investments.
How does the capital market work?
To understand how the capital market works, imagine a system where different agents interact with a common goal: moving resources efficiently. On one side are companies that need money to expand their businesses. On the other, investors who want to put their resources to work in search of returns.
Companies issue securities such as shares or debentures, which are purchased by investors seeking profit or a share in the company's results. This process is intermediated by brokerage firms and investment banks, which facilitate trading and ensure that everything takes place according to the rules set by regulatory bodies, such as the Brazilian Securities and Exchange Commission (CVM).
The main participants in the capital market are:
- Companies: seeking to raise funds for new projects, expansion or restructuring.
- Investors: individuals, investment funds or institutions that put their money to work expecting a financial return.
- Brokerage firms and investment banks: which intermediate the trades, offering platforms and guidance to investors.
- Regulatory bodies: which ensure the transparency and security of operations.
Practical example: IPO
A very common example in the capital market is the IPO, short for Initial Public Offering. It is the process by which a company goes public and has its shares traded on the stock exchange.
Here is how it happens:
- Decision to go public: the company decides it wants to raise funds in the market and begins to prepare.
- Hiring advisors: it hires investment banks and law firms to handle the process.
- Registration with the CVM: the company must submit documents and be approved by the Brazilian Securities and Exchange Commission.
- Pricing: an analysis is carried out to set the initial price of the shares to be offered.
- Share launch: the shares are sold to the public in an initial offering and begin trading on the exchange.
For example: imagine a gym chain that wants to expand to other cities. To do so, it carries out an IPO and sells part of its shares on the stock exchange. With the money raised, the company opens new locations and, at the same time, its investors begin to share in future profits, through share price appreciation or dividend payments.
Main capital market instruments
The capital market offers a variety of instruments for those who want to invest or raise funds. Each has its own characteristics, risks and objectives. Knowing these instruments helps you choose the best options according to each investor's profile and goals. Below, we will take a closer look at how each one works.
Shares
Shares represent a small portion of a company's share capital. When you buy a share, you become a part-owner of that company, sharing in the profits (dividends) and in the appreciation of the shares over time.
In the capital market, shares are traded on the stock exchange, where the price varies according to supply and demand, as well as economic factors and the company's own performance.
Debt securities (Debentures)
Debentures are debt securities issued by companies that need to raise money to finance their projects, pay off debts or expand their operations. When buying a debenture, the investor is, in practice, lending money to the company, which commits to repaying the amount invested plus interest on a future date.
This type of security is attractive to companies because it offers an alternative to bank financing, often at lower cost. For the investor, debentures can be an opportunity to earn higher returns than those offered by other fixed-income investments, such as savings accounts.
Investment funds
Investment funds work like a pool of investors. Several people put their money into a fund, which is managed by a specialized professional (the fund manager). This leader decides where to invest the fund's assets, which may include shares, debentures, real estate and other assets, depending on the type of fund.
One of the main advantages of investing in funds is convenience: the investor does not need to worry about choosing directly where to invest, as that is the fund manager's job. Moreover, by pooling the resources of several investors, the fund has greater bargaining power and access to opportunities that could be hard to reach individually.
The role of the stock exchange
The stock exchange is the environment where capital market assets are traded, such as shares, debentures and real estate investment funds. It works as a large platform that connects buyers and sellers in an organized, secure and transparent manner.
In addition to enabling the buying and selling of these assets, the exchange also establishes clear rules to ensure that all trades follow fair standards. In other words, it supervises, requires disclosures from companies and provides technology systems that make transactions fast and reliable. In Brazil, the main stock exchange is B3 (Brasil, Bolsa, Balcão).
Through the stock exchange, investors can easily put their money into companies and other assets, while companies access resources to expand their businesses. The organization the exchange provides is essential to give security and credibility to all parties involved in the capital market.
What is liquidity?
In the capital market, liquidity is the ease and speed with which an asset can be converted into cash without losing value. The easier it is to sell an asset at a fair price, the greater its liquidity.
Liquidity matters because it gives the investor flexibility. If you hold a highly liquid asset, you can sell it quickly if you need cash or want to seize another investment opportunity. Assets with low liquidity, on the other hand, may take longer to sell, and you will often have to accept a lower price to sell quickly.
How to start investing in the capital market?
Investing in the capital market may seem complicated at first, but with a simple step-by-step approach, anyone can take their first steps safely. The most important thing is to start with planning and information.
Define your goals
Before investing, it is essential to know why and for what purpose you want to put your money to work. Having clear goals helps you choose the right investments and avoids hasty decisions.
There are short-, medium- and long-term goals. Each requires different strategies. Here are some examples:
- Short term (up to 1 year): saving money for a trip, buying a specific item or building an emergency fund.
- Medium term (1 to 5 years): buying a new car, making a down payment on a home or taking a specialization course.
- Long term (over 5 years): retirement, securing your children's education or achieving financial independence.
Knowing how long you intend to keep your money invested will help you determine which instruments are most suitable.
Choose the right instruments
After setting your goals, it is time to choose where to invest. In the capital market, you can opt for shares, debentures or investment funds, among other instruments. The choice depends on your investor profile and the level of risk you are willing to take.
- Conservative profile: seeks safety and prefers lower-risk investments. Can start with debentures from solid companies or fixed-income funds.
- Moderate profile: accepts a little more risk in exchange for better returns. May combine multi-strategy funds with shares of stable companies.
Aggressive profile: tolerates larger swings and seeks high returns. May invest in higher-risk shares, equity funds or even in startups from the world of entrepreneurship and innovation, depending on the strategy.
Ideally, you should build a diversified portfolio, balancing safety and returns according to your goals.
Seek knowledge
The capital market demands constant learning. The more you learn, the better prepared you will be to make good decisions and avoid pitfalls. So never invest without first understanding well where you are putting your money.
The capital market and agribusiness
The capital market has proven to be an important ally in financing Brazilian agribusiness. Through it, rural producers and companies in the sector can access resources to invest in technology, expand production and improve infrastructure.
This relationship has strengthened in recent years, mainly because agribusiness is one of the main engines of Brazil's economy, accounting for a large share of exports and GDP.
With the growing demand for credit and the need to diversify funding sources, the capital market emerged as an attractive alternative to traditional bank credit. It offers more competitive costs and allows investors to participate directly in the sector's development.
Instruments for agribusiness
There are specific instruments in the capital market aimed at agribusiness. One of the best known is the CRA (Agribusiness Receivables Certificate). This security is issued by securitization companies and represents a promise of payment backed by receivables (amounts to be received) from operations linked to the agribusiness chain.
It works like this: a company or rural producer with amounts to be received in the future can bring that money forward by issuing a CRA, raising funds today to invest in production. In return, the investor who buys this security receives a return, which can be fixed (an amount set at the time of purchase) or floating (tied to an index, such as inflation).
