Have you ever noticed how two shares of the same company can have different rights on the stock market? In common and preferred stock, the difference goes beyond the ticker symbol and changes the vote, dividends and even the profile of the buyer.
For the novice investor, understanding this distinction helps ensure a safer transition from a savings account. It also prevents impulsive decisions, since ON and PN do not serve the same purpose.
What Are Common Stocks?
Common stock represents a stake in the company and grants voting rights at shareholders' meetings. In practice, anyone who buys this type of stock participates in corporate decisions, even if they do not always have the power on their own to change everything.
It's a choice that typically appeals to those who value corporate governance and want to follow the company more closely. Among common and preferred stock, NGOs are moving closer to the idea of “having a say” in business, even if it’s a small one.
If you like to understand the company's direction, this structure makes sense. In many cases, long-term investors prefer ON because they see greater alignment between control, transparency, and corporate succession.
In practice, think of it this way: when you buy a class of shares, you’re not just looking for a return. You’re also joining the conversation on relevant topics, such as mergers, reorganizations, and board elections.
This is particularly evident among companies listed on B3 that use the fractional market, because a beginner investor can start with just a few shares and learn how stock ownership works without having to make large investments.
What Are Preferred Shares?
Preferred shares, or PNs, typically offer economic priority over common shares (ONs). In general, this means a greater chance of receiving dividends earlier or receiving certain benefits provided for in the articles of incorporation.
But be aware: preference does not guarantee payment. In common and preferred stock, the PN offers a corporate benefit defined in the company's internal policy, not an absolute promise of returns.
In an investor’s day-to-day routine, this may appeal to those seeking a more predictable stream of income. Still, it’s important to review the articles of incorporation and understand how the company distributes its earnings, because the policy may change.
In our analyses, we’ve noticed that many beginners confuse PN with “a stock that always pays the highest dividends.” It’s not quite that simple. Historical performance helps, but it doesn’t replace a thorough analysis of the business.
If you'd like to explore this further, it's worth comparing it with the material on PN Shares, which provides details on this type of security with a greater focus on preferred dividends.
Common and Preferred Stock
Now it's easier to compare. Among common and preferred stock, the key difference lies in voting rights and economic priority. This changes both the investor’s experience and the way the company is analyzed.
Those seeking influence in corporate governance tend to look first at ON. On the other hand, those who prioritize potential returns typically pay closer attention to PN, always checking the company’s rules.
To get a clearer picture, see the direct comparison below.
| Criteria | Common Stock (ON) | Preferred Stock (PN) |
|---|---|---|
| Right to vote | They usually have voting rights at meetings | They generally do not have the right to vote, or their right to vote is restricted |
| Dividend Priority | They don't usually have a particular preference | They may have priority or an economic advantage |
| Main focus | Corporate Governance and Shareholder Participation | Earnings Potential and Preferential Treatment |
| Most suitable profile | An investor who values voting rights and control | Investors seeking income and simplicity |
In practice, common and preferred stock It’s not a matter of “better” or “worse.” The decision depends on the objective. If the goal is to track company decisions, ON may be a better fit.
If the focus is on analyzing earnings distribution, PN may be more attractive. However, investors need to consider liquidity, dividend history, and corporate structure before buying.

Shareholder Rights in Practice
In real life, shareholder rights come into play at specific times. This includes voting at shareholder meetings, receiving dividends when the company distributes profits, and monitoring decisions that may affect the stock's value.
If you want to have a greater say in the company's direction, ONs make more sense. If you prefer to track results without getting too involved in governance, PNs may seem simpler.
A concrete example: Imagine a company discussing changes to its board. Those with voting rights can participate in that decision. Those without voting rights, on the other hand, observe the impact on the stock price and earnings, but have no direct influence.
“Investors should be aware of the rights and obligations associated with the securities they purchase, especially in the case of publicly traded companies.” — CVM, in investor guidance.
This kind of guidance helps distinguish between expectations and reality. In common and preferred stock, rights vary depending on class and social status, so reviewing the company's documentation is part of the decision-making process.
Institutional sources such as the CVM and B3 They are great starting points for understanding shareholder meetings, corporate events, and the logic behind negotiations.
Advantages and disadvantages of each one
The main advantage of ONs is the voting right. This can be important in companies with good corporate governance, especially when investors take a long-term view and want to monitor strategic changes.
On the other hand, PNs may offer more favorable financial terms in certain structures. In practical terms, this could mean priority in dividends or some protective mechanism provided for in the articles of incorporation.
The trade-off is clear: a vote alone doesn't pay the bill, and economic priorities are no substitute for a thorough analysis of the company. In common and preferred stock, you trade one benefit for another, with no automatic guarantee of a higher return.
Consider a simple scenario. If a company pays R$ 1 per share in dividends and a class of stock has a preference of 10%, that share could receive R$ 1.10 per share, depending on the company’s bylaws. This is an illustrative example, not a promise.
There is also the issue of liquidity. Some ONs and PNs trade very well; others barely move at all. This affects price, spread, and ease of buying and selling, especially for those trading smaller amounts.
In practice, investors look at three things at the same time: governance, returns, and trading. If one of these areas is weak, the supposed advantage of that asset class can quickly lose its appeal.
How to choose between them
Choosing between ON and PN is easier when you start with your goal in mind. There’s no single right answer, because the best role depends on your stage of life and your strategy.
In common and preferred stock, the focus should be on alignment. Those who want to participate in decision-making tend to look at ON. Those seeking a more predictable distribution tend to pay closer attention to PN.
Use these criteria before making a decision:
- Main objective: voting and governance or the pursuit of financial gain.
- Risk tolerance: greater interest in control or in economic predictability.
- Asset liquidity: Frequently traded securities reduce exit difficulties.
- Company History: Dividends, debt levels, and management quality are very important.
- Horizon: The short term calls for extra attention to liquidity; the long term requires business quality.
If your goal is to build your portfolio gradually, you can start by keeping your choices simple. Instead of searching for “the perfect stock,” it’s worth comparing actual companies and figuring out whether the chosen sector aligns with your plan.
In our work with beginners, we've realized that the worst decision is to buy a stock based solely on its name. The class matters, but the business behind it matters even more.
Examples of publicly traded companies
On B3, it is common to find companies with both classes. This helps illustrate how common and preferred stock They enter the job market in a practical way, without having to memorize theory.
A well-known example is the Petrobras, with PETR3 to ON and PETR4 for PN. Another classic example is Vale, which primarily trades ON shares, showing that not every company offers both classes in the same way.
There are also companies like Itaú Unibanco, with ITUB3 e ITUB4, where the investor checks the ticker to see whether they are buying ON or PN. This detail changes how the stock is interpreted, even within the same company.
For those just starting out, the first step is simple: look at the end of the ticker symbol. Generally, the number 3 indicates ON and the number 4 indicates PN, although it’s always a good idea to check the company’s profile on B3.
If you want to better understand how tickers and trading work, B3 maintains institutional pages about listed companies and their securities, which helps avoid common misunderstandings.
Common Mistakes Made by Beginners
A common mistake is buying a stock simply because it pays dividends. While this may be tempting, it is no substitute for analyzing the business, its debt, and the consistency of its dividend payments.
Another misconception is to think that preference means a guaranteed return. In common and preferred stock, the PN may provide for a benefit, but the company may still reduce or suspend payments depending on its circumstances.
It is also common to overlook governance. Companies with more complex ownership structures may concentrate power in the hands of a few controlling shareholders, and this changes the way ON and PN behave over time.
There are still those who buy based on the face value, believing that a cheap stock is a good stock. One share of R$ 10 is not necessarily better than another share of R$ 40. What matters is the value of the investment and the price paid for it.
Another sensitive issue is confusing rumors with information. Before taking a position, it’s worth reviewing relevant facts, financial statements, and official announcements. This precaution helps avoid decisions based solely on “hot tips.”.
Summary to Help You Make a Better Decision
If you’re looking for governance and voting rights, an ON tends to make more sense. If the priority is to seek economic benefits provided for in the corporate bylaws, a PN may be worth considering. In common and preferred stock, the key point is its purpose.
Before buying, compare the company, its liquidity, track record, and the type of rights the security offers. If you want to proceed with greater confidence, it’s also worth reading the guide on which one to choose and build your portfolio more thoughtfully.

Frequently Asked Questions About Common and Preferred Stock
What is the main difference between common stock and preferred stock?
The key difference lies in voting rights and economic priority. Common stock grants the right to participate in shareholder meetings, while preferred stock typically offers priority in dividends or other benefits provided for in the company's articles of incorporation.
How do you choose between ON and PN when investing?
If the goal is to participate in corporate governance and monitor corporate decisions, open-end funds (ON) tend to make more sense. If the priority is to seek predictability in returns, closed-end funds (PN) may be more attractive—though the fund’s bylaws should always be reviewed.
What benefits can preferred stock offer?
Preferred stock may grant priority in the receipt of dividends or other economic rights defined by the company. However, this advantage does not guarantee payment, as it depends on the company’s performance and the stock’s internal terms.
Is it true that preferred shares always pay higher dividends?
No. This is a common myth among novice investors. For common and preferred stock, the PN may take priority, but that does not mean a higher yield in all cases. The track record helps, but it is no substitute for reading the articles of incorporation.
Why does understanding common and preferred stock help beginner investors?
Because this difference affects the nature of your ownership stake in the company and prevents impulsive decisions. Knowing whether a share carries voting rights or economic priority helps you align your purchase with your objective, whether it’s governance or the pursuit of returns.
