Every financial journey begins with a well-structured investment portfolio.
Have you ever thought about investing, but felt it was too complicated?
Building an investment portfolio can be simpler when you understand the basics.
Many people believe that investing is only for experts.
In practice, starting an investment portfolio is a realistic step for anyone who wants to take care of their financial future.
By spreading your money across different assets, you create a more balanced wealth-building growth strategy.
This article shows how to build your portfolio and which options to use. The principles make a difference in the long run..
What is an investment portfolio?
An investment portfolio is the set of all financial assets 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 investing all their money in 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 come with more fluctuations. Others are more stable, but generally grow more slowly.
The first step: Build an emergency fund
Before thinking about financial growth, there is one essential step: building an emergency fund.
This reserve works as a financial cushion to handle unexpected day-to-day situations.
Among the most common unexpected 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 who work as freelancers, this amount can reach 12 months of expenses.
An emergency fund should have some important characteristics:
- High liquidity
- Low risk
- Quick access to money
Only after creating this solid foundation does it make sense to start building an investment portfolio focused on growth.

What percentage should be invested in fixed income?
Fixed income generally works 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 usually have characteristics such as:
- Low volatility
- Predictability of returns
- Greater stability in 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 can vary according to the investor’s profile.
Another well-known concept is the 100 minus your age rule.
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.
What percentage of the portfolio should be allocated to stocks?
Stocks generally represent the growth portion of an investment portfolio.
When you buy stocks, you are acquiring small ownership stakes in companies.
If these companies grow and increase in value, stock prices also tend to rise over time.
Historically, stocks have shown greater long-term return potential.
On the other hand, they also come with greater volatility, which means they can rise and fall more sharply.
For this reason, the proportion of stocks in 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 a portfolio?
Cryptocurrencies are considered high-risk, high-volatility assets.
They can generate significant gains at certain times, but they can also experience sharp 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
- In many traditional portfolios, it reaches around 5%.
The idea is not to base the entire strategy on cryptocurrencies. Instead, they can serve as an additional element of portfolio diversification.
If the market rises significantly, the investor takes part in the growth.
If a decline occurs, the impact on the total portfolio remains limited.

Common mistakes when building your first investment portfolio
When building your first investment portfolio, many beginners make some very common mistakes.
Knowing these mistakes can help you 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.
Investing all your money in a single asset.
A lack of diversification significantly increases portfolio risk.
Chasing quick gains
Solid investments are usually built with a long-term perspective.
Blindly following market trends
Investing in assets just 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 they come with very high volatility.
The big lesson is to remember that investing is not a short sprint.
How to balance and adjust your portfolio over time
An investment portfolio is not 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% in stocks
- 40% in fixed income
After a strong stock market rise:
- 75% in stocks
- 25% in 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 a year
- Or when the difference exceeds 5% to 10%.
This process helps keep 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 really makes a difference is starting early and staying consistent over time.
Over the years, even small contributions can grow significantly thanks to the power of compound interest.
This means that the most important factor is not finding the perfect investment.
Most of the time, the most important thing is simply taking the first step.
