Understanding the different types of investment portfolios

Building an investment portfolio is about more than just choosing between shares, bonds, property, cash, or funds.

The right portfolio for you depends on why you are investing, how much risk you can afford, how long your money can remain invested, and whether you need growth, income, or a balance of both.

That is why different investors often hold very different portfolios, even when investing the same amount. A 30-year-old investing for long-term growth may need a very different approach than someone approaching retirement who is looking to protect their capital.

In this guide, we explain the main types of investment portfolios, how they are often structured, and how factors such as risk tolerance, age, and financial objectives can influence your approach.

If you would like support with your investment decisions, our wealth management team can help you build a portfolio around your personal goals and circumstances.

What is an investment portfolio?

An investment portfolio is a collection of assets held by an individual, family, trust or business.

A portfolio is often made up of several different classes of assets, such as:

Equities (also known as stocks and shares)
Fixed-income investments (such as government or corporate bonds)
Cash or short-term deposits
Property
Alternative investments (such as commodities, infrastructure, private equity, or hedge funds)

The mix of these assets is known as asset allocation. This is one of the most important parts of investment planning.

A portfolio with a high proportion invested in stocks and shares may offer greater growth potential, but it is also likely to experience increased volatility. A portfolio with a higher proportion invested in bonds and cash may be less volatile, but may not grow as strongly over the long term.

There is no single ‘best’ investment portfolio. The right structure depends on your goals.

Portfolios by financial objective

One way to understand investment portfolios is to start with an objective. In simple terms, are you trying to grow your capital, generate income or achieve a mixture of the two?

Growth investment portfolios

A growth portfolio is designed to increase in value over several years.

It may produce little or no regular income. Instead, the aim is for the underlying investments to grow over time. This type of portfolio often includes shares in companies that reinvest profits into expansion, innovation, acquisitions, or new markets.

Growth portfolios may suit people who can remain invested for many years. That is because the value of the investments may fluctuate, sometimes significantly, depending on market conditions. A younger investor building wealth over several decades may be more comfortable with this volatility. Someone who expects to need the money in the next few years may not be.

Growth investing can play an important role in long-term financial planning. However, higher growth potential tends to come with higher risk.

Income investment portfolios

An income portfolio is designed to produce regular payments.

These payments may come from dividends, bond interest, rental income, or other income-generating assets. The aim is usually to provide a steady stream of income while preserving as much of the underlying capital as possible.

Income portfolios are often used by people who want to supplement earnings, support retirement income, or draw money from investments in a structured way.

They may include:

Government bonds
Corporate bonds
Dividend-paying shares
Property funds
Multi-asset income funds

While these portfolios are designed to generate income, they are not risk-free. Dividends can decline or be suspended, bond values can fall, and a portfolio's capital value can fluctuate.

For these reasons, when you build an income investment portfolio, you should consider both the amount of income you need and how sustainable that income is likely to be.

Portfolios by risk tolerance

Risk tolerance is about how comfortable you are with investment uncertainty.

However, it is not the only question. You also need to consider your capacity for loss. In other words, how much could your portfolio fall before it affected your plans?

You may feel comfortable with investment risk in theory, but if a large drop in value would damage your retirement plans (for example), your portfolio may need to be more cautious.

The Financial Conduct Authority’s guidance on investing emphasises the importance of having your day-to-day finances in order before investing. It also highlights diversification as one way to spread risk across your investment portfolio.

Aggressive portfolios (e.g., the 70/30 or 80/20 split)

An aggressive portfolio takes calculated risks in pursuit of higher long-term returns.

This type of portfolio usually has a high allocation of equities (stocks and shares). For example, an investor might hold 70% or 80% in shares and 20% or 30% in bonds, cash, or other lower-risk assets.

An aggressive portfolio may include exposure to:

Global equities
Smaller companies
Technology stocks
Emerging markets
Specialist sectors
Higher-risk funds

These investments can deliver strong returns in good periods. They can also fluctuate sharply when markets are under pressure.

That means aggressive portfolios are usually better suited to investors who have the time to stay invested and recover from market downturns. They may be less suitable for someone close to retirement or who needs to draw money from their portfolio soon.

An aggressive portfolio should still be built with careful consideration. It shouldn’t be based solely on chasing whatever has performed well recently or on investing in something because lots of other people are doing so. For example, an investor may choose a high-equity portfolio because they have many years to invest and can accept short-term falls. That is different from buying into a fashionable sector after it has already risen sharply or selling in a panic during a downturn.

Our guide on behavioural finance explains how emotions and behavioural bias can affect investment decisions, often for the worse.

Defensive and balanced portfolios (e.g., the 60/40 split)

Defensive and balanced portfolios place greater emphasis on risk management than their aggressive counterparts.

A highly defensive portfolio may hold a higher proportion of bonds, cash-like holdings, and other lower-volatility assets. A balanced portfolio usually maintains greater exposure to equities while still aiming to reduce the impact of sharp market falls.

One well-known example is the 60/40 portfolio. This means 60% of your portfolio is invested in equities, while 40% is in bonds. The equity portion offers the potential for higher returns, while the bond portion is designed to give an element of stability.

The 60/40 approach is often described as a traditional balanced portfolio for moderate-risk investors. However, it should not be treated as a universal rule, as it may be too cautious for one investor and too risky for another.

It is also worth remembering that lower risk does not mean risk-free. Bond values can fall, cash-like holdings can lose spending power through inflation, and any investment portfolio can go down as well as up.

Portfolios by management style

Another way to classify portfolios is by how the investments are selected and managed.

Some portfolios are actively managed by fund managers or investment managers. Others use passive funds that track a market index.

The right approach may involve one style or a combination of several.

Passive investing (index tracking)

Passive investing involves tracking the composition of a market index rather than trying to beat it.

For example, a passive fund might track the FTSE 100, the S&P 500 or a global equity index. The fund does this by holding the same investments as the index, or a representative sample of them, so that its performance broadly follows the market it tracks.

Passive investing is often lower-cost than active management. It can also be simple and transparent, as investors can see which market the fund is designed to track.

However, passive investing does not remove investment risk. If the market being tracked declines, the passive fund will usually follow suit.

A passive portfolio may suit investors who want broad market exposure, lower costs, and a straightforward investment approach. It may be less suitable for those who want active decisions around risk, sectors, markets, or specific opportunities.

Value investing

Value investing involves looking for investments that appear undervalued.

The idea is to buy assets that may be worth more than their current price suggests. This often means looking for companies that are out of favour with the market, but which have strong fundamentals or recovery potential.

Value investing can be rewarding when the market eventually recognises the asset’s worth. However, it can also be risky. An investment may look cheap for a good reason. The expected recovery may not happen, or it may take much longer than expected.

Socially responsible (ESG) portfolios

A socially responsible or ESG portfolio considers environmental, social, and governance factors when selecting investments.

ESG portfolios consider:

Environmental, such as climate impact and resource use
Social, such as employment practices and community impact
Governance, such as board structure and corporate behaviour

Some ESG portfolios avoid certain sectors, such as tobacco, gambling, or weapons. Others focus on companies that meet specific sustainability or governance standards.

An ESG approach can be combined with other investment styles. For example, an investor could hold a growth-focused ESG portfolio, an income-focused ESG portfolio, or a balanced portfolio that includes ESG funds.

It is important to look carefully at how each fund defines ESG. Not all funds use the same criteria, and investors may have different views about what responsible investing should include.

What is the best investment portfolio for your age?

Age can be an important factor in portfolio planning, but it should not be the only factor considered.

Instead, ask yourself when you will need the money and what you will need it for.

A 30-year-old investing for retirement may have several decades before they need to access the money. That longer time period may allow them to accept more short-term volatility in return for long-term growth potential.

For example, they might hold a higher proportion of equities through a growth or aggressive portfolio. If markets fall, they have more time to wait for recovery.

By contrast, a 70-year-old entering retirement may need a more cautious approach. They may be drawing income from the portfolio and may not have time to recover from a major market fall. This is where de-risking becomes important, gradually reducing investment risk as the point of needing the money approaches. For someone approaching retirement, this may involve shifting part of the portfolio away from higher-risk growth assets and towards income-generating or lower-volatility investments.

This does not mean all risk should be removed. A retirement planning portfolio may still need some growth, especially if it has to provide income for many years. However, sudden falls can be more damaging when withdrawals are being taken from the portfolio.

This is known as the sequence-of-returns risk. It means the order of investment returns can matter, not just the average return. A major fall early in retirement can be especially harmful if money is being withdrawn at the same time.

That is why retirement portfolios need careful planning and must balance income, growth, inflation, capital preservation, and flexibility.
