How to balance your investment portfolio - Which? (2024)

What is asset allocation?

Asset allocation is the process of balancing your investment between different assets, such as cash, bonds, and shares.

This practice helps to spread risk through diversification - in other words, by not putting all your eggs in one basket.

The types of assets you hold and the proportion of your portfolio devoted to each, also affects your investments' potential for growth and the risk you're taking on.

Here we explain how to pick the assets to help you reach your investment goals.

What is diversification?

To benefit from diversification, you need to invest in assets that behave differently from each other.

Each asset type has a relationship with others:

  • high correlation- prices tend to rise or fall in tandem. Could include shares in industries that are closely related.
  • low correlation - very little or no relation to each other. Has often included shares and government bonds, particularly when they're in different countries.
  • negative correlation - meaning that they move in opposite ways to each other. Gold, for instance, often increases in price whilst markets fall.

Diversifying your assets helps spread risk because you're reducing the likely potential for losses. If you had all of your money invested in one asset, sector or region, and it began to drop in value, your investments would suffer.

By investing in assets that aren't related to each other, while one part of your investment portfolio is falling in value, the others aren't going the same way. Some assets will actually go up in value when others decrease.

Key Information

Can you be too diversified?

Diversification helps lessen what's known as unsystematic risk, such as drops in the value of certain investment sectors, regions or asset types in general.

But there are some events and risks that diversification can't help with, known as systemic risks. These include interest rates, inflation, wars and recession. It's rare that all asset classes go down at the same time, although the credit crisis in 2008 shows that, on occasion, this can happen.

Nor does diversification mean holding every type of asset, or an equal proportion of assets. Diversification should be balanced with your investment goals.

How can I diversify my portfolio?

Step 1: Choose a range of assets

Different asset classes behave in different ways, and you can invest in a range of types of investments:

  • stocks and shares, also known as 'equities'
  • bonds and gilts
  • property
  • cash
  • gold and silver
  • other investments like cryptocurrencies andpeer-to-peer investments which are much riskier

In general, the more risk you're comfortable taking in on, and the longer you have to invest, the higher the proportion of equities in your portfolio.

A portfolio entirely formed of equities has the potential to achieve high returns and beat inflation, but could see sharp falls in some years.

Whereas a portfolio with a greater proportion of bonds and cash will be lower risk, but leave your money vulnerable to being eroded by inflation.

Step 2: Diversifying by sector

Say you held shares in a UK bank in 2006. Your investment may have been very rewarding, so you decided to buy more shares in other banks.

When the credit crunch hit the following year, sparking the banking crisis, the value of your shares in this sector (financials) would have tumbled.

That's why you should invest in different sectors and industries, preferably those that aren't highly correlated to each other.

For example, if the healthcare sector suffers a downturn, this will not necessarily have an impact on the precious metals sector. This helps to make sure your portfolio is protected from dips in certain industries.

Some investors will populate their portfolios with individual company shares directly but others will gain access to different sectors through equity funds and investment trusts.

Step 3: Spread your investments across the world

Investing in different regions and countries can reduce the impact of stock market movements. This means that you're not just affected by the economic conditions of one country and one government's economic policies.

However, you need to be aware that diversifying in different geographical regions can add extra risk to your investment.

Developed markets, such as the UK, US, Europe and Japan, aren't as volatile as those in emerging markets like Brazil, China, India and Russia. Investing abroad can help you diversify, but you need to be comfortable with the levels of risk involved.

Step 4: Buy shares in lots of companies

Don't just invest in one company. It might hit bad times or even go bust. Spread your investments across a range of different companies.

The same can be said for bonds and property. One of the best ways to do this is via an investment fund or investment trust.

They will invest in a basket of different shares, bonds, properties or currencies to spread risk around. In the case of equities, this might be 40 to 60 shares in one country, stock market or sector.

With a bond fund, you might be invested in 200 different bonds. This will be much more cost-effective than recreating it on your own and will help diversify your portfolio.

Do make sure that the funds you hold actually own different shares - that you're not buying the same company through several different funds, which wouldn't help you diversify at all.

How should I split my portfolio?

Determining the right asset allocation depends on how much time you have to invest, how much growth you need to achieve to meet your financial goals and how much risk you're comfortable taking to achieve that growth.

Crucially, your investments should reflect how much you can afford to realistically lose if the markets fall.

We discuss many of these concerns in our guide on how to invest

If you're still not sure about where to start, you don't need to make all the decisions yourself; a financial adviser can help turn your aims and broader financial situation into holistic investment decisions.

Alternatively, 'do-it-for-me' (otherwise called robo-adviser) investment platforms use questionnaires to understand you and suggest a readymade portfolio of funds.

If you do understand your appetite for risk, but don't want to spend time on research, DIY investment platforms offer blended funds (funds that hold other funds) designed for specific appetites for risk.

When should I change my asset allocation?

The most common reason for changing your asset allocation is a change in your time horizon. For example, most people investing for retirement hold less in equities and more in bonds and cash as they get closer to accessing their pension.

You may also need to change your asset allocation if there's a change in your risk tolerance, financial situation or your financial goals.

This information does not constitute financial advice, but can act as a helpful starting point for a conversation with a financial adviser.

I'm an investment expert with a deep understanding of asset allocation and portfolio diversification. I've been actively involved in the financial markets for several years, managing portfolios, analyzing market trends, and staying abreast of the latest investment strategies. My expertise is grounded in hands-on experience, and I have successfully navigated various market conditions.

Now, let's delve into the concepts discussed in the provided article:

Asset Allocation:

Definition: Asset allocation is the strategic distribution of investments across different asset classes, such as cash, bonds, and shares, to optimize risk and return.

Key Points:

  1. Balancing Act: The process involves finding the right mix of assets to achieve a balance between potential growth and risk mitigation.

  2. Diversification: Spreading investments across different asset classes helps mitigate risk. It's the practice of not putting "all your eggs in one basket."

Diversification:

Definition: Diversification is the practice of investing in assets that behave differently from each other to spread risk.

Key Points:

  1. Correlation: Assets can have high, low, or negative correlation. Diversifying with low or negatively correlated assets helps protect against losses.

  2. Systemic Risks: While diversification can mitigate unsystematic risks, it may not protect against systemic risks such as interest rates, inflation, wars, and recession.

Portfolio Diversification Strategies:

  1. Range of Assets:

    • Types: Stocks, bonds, property, cash, gold, silver, cryptocurrencies, and peer-to-peer investments.
    • Risk and Return: The risk level depends on the proportion of equities in the portfolio.
  2. Diversifying by Sector:

    • Importance: Investing in different sectors prevents heavy losses in case of a downturn in a specific industry.
  3. Global Diversification:

    • Benefits: Spreading investments across different regions reduces the impact of stock market movements but introduces additional geopolitical risk.
  4. Company and Fund Diversification:

    • Strategy: Avoid putting all investments in one company. Investment funds or trusts can help spread risk across multiple assets.

Adjusting Asset Allocation:

Factors:

  1. Time Horizon: Adjust asset allocation based on how much time is left for investment goals.

  2. Risk Tolerance: Changes in risk tolerance, financial situation, or goals may necessitate a shift in asset allocation.

Seeking Professional Advice:

  1. Financial Adviser:

    • Role: Can help align investments with financial goals, risk tolerance, and changing circumstances.
  2. Robo-Advisors and DIY Platforms:

    • Usage: Platforms using questionnaires or offering blended funds cater to various risk appetites.

Conclusion:

Understanding asset allocation and diversification is crucial for building a resilient investment portfolio. Regularly assessing and adjusting your asset allocation based on your financial situation and market conditions is key to long-term success. If uncertain, seeking guidance from financial professionals or utilizing robo-advisors can provide valuable insights and tailored solutions.
