Every financial journey begins with a well-built investment portfolio.
Have you ever thought about investing but felt it seemed too complicated?
Building an investment portfolio can be simpler when you understand the basics.
Many people believe investing is only for specialists.
In practice, starting an investment portfolio is a possible step for anyone who wants to take care of their financial future.
By distributing money among different assets, you create a more balanced growth strategy.
This article shows you how to build your portfolio and which principles make a difference in the long term.
What an Investment Portfolio is
An investment portfolio is the set of all financial assets that a person owns with the goal of generating returns over time.
These assets can include different types of investments, such as:
- Company stocks
- Fixed-income securities
- Investment funds
- ETFs
- Real estate or real estate funds
- Commodities
- Cryptocurrencies
Instead of putting all the money into a single asset, the investor divides their capital among several options. This process is known as diversification.
The logic behind this strategy is simple.
Some investments offer greater growth potential, but present more fluctuations. Others are more stable, but usually grow more slowly.
The First Step: Building an Emergency Fund
Before thinking about financial growth, there is an essential step: creating an emergency fund.
This reserve works as a financial cushion to deal with unexpected situations in daily life.
Among the most common unforeseen situations are:
- Job loss
- Unexpected medical expenses
- Urgent home repairs
- Family problems or financial emergencies
The most common recommendation among experts is to save the equivalent of 3 to 6 months of basic expenses.
For people with variable income or freelance work, this amount may reach up to 12 months of expenses.
An emergency fund should have some important characteristics:
- High liquidity
- Low risk
- Quick access to the money
Only after creating this solid foundation does it make sense to start building an investment portfolio focused on growth.

What Percentage to Invest in Fixed Income
Fixed income usually functions as the stability base within an investment portfolio.
This group includes assets such as:
- Government bonds
- Corporate bonds
- Bank certificates
- Fixed-income funds
These investments generally present characteristics such as:
- Lower volatility
- Predictability of returns
- Greater stability during times of crisis
A widely known model in the international financial market is the so-called 60/40 portfolio. In this model, the portfolio is divided between:
- 60% in stocks
- 40% in fixed income
But this proportion is not a universal rule. It may vary according to the investor’s profile.
Another well-known concept is the rule 100 minus your age.
According to this strategy, the percentage invested in stocks could be approximately 100 minus the person’s age.
For example:
- 30 years old → about 70% in stocks
- 40 years old → about 60% in stocks
This approach helps reduce risk as the investor gets older.
How Much of the Portfolio Should Go to Stocks
Stocks usually represent the growth portion of an investment portfolio.
When you buy stocks, you are acquiring small ownership stakes in companies.
If those companies grow and increase in value, stock prices tend to rise over time.
Historically, stocks have shown greater long-term return potential.
On the other hand, they also present greater volatility, meaning they can rise and fall more intensely.
For this reason, the proportion of stocks within an investment portfolio usually varies according to the investor’s profile.
- Conservative profile
About 20% to 30% in stocks - Moderate profile
About 40% to 60% in stocks - Aggressive profile
About 70% to 90% in stocks
Many beginner investors do this through ETFs and index funds, which allow investment in hundreds of companies at the same time.
Is it Worth Including Cryptocurrencies in the Portfolio?
Cryptocurrencies are considered high-risk and high-volatility assets.
They can generate significant gains at certain times, but they can also experience rapid declines.
For this reason, experts often recommend small exposure within an investment portfolio. Some common guidelines in the financial market include:
- 1% to 2% for conservative investors
- 2% to 5% for moderate investors
- Up to about 5% in many traditional portfolios
The idea is not to base the entire strategy on cryptocurrencies. Instead, they can function as an additional element of portfolio diversification.
If the market rises significantly, the investor participates in the growth.
If a decline occurs, the impact on the total portfolio remains limited.

Common Mistakes When Building the First Investment Portfolio
When building their first investment portfolio, many beginners make some very common mistakes.
Knowing these mistakes can help avoid them from the start. Among the most frequent are:
Investing without clear goals
Without defined financial goals, it becomes difficult to build a consistent strategy.
Putting all the money into a single asset
Lack of diversification significantly increases portfolio risk.
Seeking quick gains
Solid investments are usually built with a long-term perspective.
Following market trends blindly
Entering assets only because they are rising can lead to losses.
Ignoring costs and fees
High fees can significantly reduce returns over time.
Not understanding risk
Some investments may seem attractive but have very high volatility.
The big lesson is to remember that investing is not a short race.
How to Balance and Adjust your Portfolio over Time
An investment portfolio is not something static. Over time, some assets may grow more than others, changing the portfolio’s original balance.
That is why there is a practice called rebalancing. Rebalancing means adjusting the portfolio percentages again to return to the original strategy.
Imagine a simple example. Initial strategy:
- 60% stocks
- 40% fixed income
After a strong stock market rise:
- 75% stocks
- 25% fixed income
In this scenario, the investor can sell part of the stocks and reinvest in fixed income to restore the planned balance.
Many experts recommend rebalancing:
- Once per year
- Or when the difference exceeds 5% to 10%
This process helps maintain the portfolio’s risk level aligned with the defined strategy.
Conclusion: Start Small, but Start Today
Building an investment portfolio does not require large amounts of money.
What truly makes a difference is starting early and maintaining consistency over time.
Over the years, even small contributions can grow significantly thanks to the power of compound interest.
This means the most important factor is not finding the perfect investment.
Most of the time, the most important thing is simply taking the first step.
