Investing mistakes to avoid

Jemma Brown • February 7, 2024

Investing successfully and improving your investment portfolio can be as much about minimising mistakes as trying to pick the ‘next big thing’. It’s all about taking a calm and considered approach and not blindly following trends or hot tips.

Let’s delve into some of the most prevalent investment mistakes and look at the principles that underpin a robust and successful portfolio.

Chasing hot and trending shares

Every so often there are industries or shares that are all over the media and you may begin to worry that you are missing out on something. Jumping on every trend is like trying to catch a wave; you might ride it for a bit, but you’re bound to wipe out sooner or later. That’s because the hot tips and ‘buy now’ rumours often don’t pass the fundamentals of investing test.

The key is to keep a cool head and remember that the real winners are often the ones playing the long game.

Not knowing your ‘why’

What would you like your investment portfolio to achieve? Understanding your motivations and goals will help you to choose investments that work best for you.

If you want to build wealth for a comfortable retirement, say 20 to 30 years down the track, you can afford to invest in riskier investments to play the long-term game. If you have already retired and plan to rely on income from your portfolio, then your focus will be on investments that provide consistent dividends and less on capital growth.

Timing the market

Timing the market involves buying and selling shares based on expected price movements but at best, you can only ever make an educated guess and then get lucky. At worst, you will fail.

As the world-renowned investor Peter Lynch wrote in his book  Learn to Earn : “Far more money has been lost by investors trying to anticipate corrections, than lost in the corrections themselves”. i

Putting all the eggs in one basket

This is one of the classic concepts of investing but it’s worth repeating because, unless you are regularly reviewing your portfolio, you may be breaking the rule.

Diversifying your portfolio allows you to spread the risk when one particular share or market is performing badly.

Diversification can include different countries (such as adding international shares to your portfolio), other financial instruments (bonds, currency, real estate investment trusts, exchange traded funds), and industry sectors (ensuring a spread across various sectors such as healthcare, retail, energy, information technology).

Avoiding asset allocation

While diversification is key, how do you achieve it? The answer is by setting an asset allocation plan in place and reviewing it regularly.

How much exposure do you want to diversify into defensive and growth assets? Within them, how much should be invested in the underlying asset classes such as domestic shares, international shares, property, cash, fixed interest and alternatives.

Making emotional investment decisions

The financial markets are volatile and that often leads investors to make decisions that in hindsight seem irrational. During the COVID-19 pandemic, on 23 March 2020 the ASX 200 was 35 per cent below its 20 February 2020 peak. ii  By May 2021, the ASX 200 crossed the 20 February 2020 peak. Many investors may have made an emotional decision to sell out during the falling market in March 2020 but then would have missed the some of the uplift in the following months in.

Many Australians don't know how their super fund has performed or what it invests in. Are you one of them? Here's what to check and why it matters. Do you know how your super fund performed over the last two years? Many Australians don’t and are working towards their financial future without fully understanding one of their most important assets and without a clear plan for how their super may support them in retirement. That's not surprising, as many people view super as something that should run quietly in the background while they're busy with careers, families and everything else that life throws at them. But when you’re not sure what’s happening behind your balance, it’s harder to know whether you’re on track, whether your current approach reflects your goals or what opportunities might be available to help you make the most of what you’ve built so far. Your super isn't sitting in an account, it's invested Super is invested by a fund on your behalf across a mix of assets, with those investments working to grow your balance over time. Those include: Shares Ownership in Australian and international publicly listed companies. Their value can rise and fall, sometimes substantially over short periods but shares can provide capital growth over the long term. Property and infrastructure Real assets like office buildings, shopping centres, airports and energy networks. They can produce income and don't always behave in the same way as share markets, helping diversify investment holdings. Fixed interest and bonds Lending to governments and companies in return for interest. They can provide regular income and be steadier than shares, although returns and risk vary depending on the investment. Cash Generally, the most stable and lowest risk investment type. It can provide stability and faster access to money but typically offers lower longer term return potential. The investment option you choose determines the mix of assets held in your super based on your risk appetite. Most super funds offer options from conservative to high growth. If you’re young, a growth option with a higher exposure to growth assets like shares could offer higher returns over time – but it also comes with higher risk. As retirement nears, you might want to consider a more conservative approach with more defensive assets, like bonds for example to protect your savings. If you've never made a choice, you're probably in your fund's default option, which is designed to suit a broad membership. It’s worth knowing whether the mix you're in matches your circumstances and goals, including how far you are from retirement. Why performance alone is not a true comparison If you're thinking about how your super compares, returns are often where people start. The trouble is that a return figure means nothing without context: What it's being compared to Growth and conservative options invest differently and with different levels of risk. Compare like with like or the comparison may not be genuine. The comparison period A single year can be heavily influenced by short term market conditions. Super is measured in decades, so five, seven and ten year returns tell you far more about whether a fund is consistently doing its job, albeit not a predictor of future performance. Fees and tax Published returns should reflect investment fees, costs and tax but administration fees may be charged separately from your balance. Two funds quoting the same return can leave you in meaningfully different places once all fees are accounted for. Then there are the things that returns can't show you at all. For example, what insurance is attached to your account and what it's costing you, whether the fund offers guidance, tools and advice or simply sends a statement once a year. Another consideration maybe the level of support available when you need it. When comparing funds, it's worth looking at the full picture, including performance, fees, investment options, retirement support and member benefits. What today’s decisions mean tomorrow To understand how your super stacks up, start here: Find your investment option It's on your annual statement and in your online account. Look at what's in it Your fund publishes the asset allocation (shares, cash etc.) for each investment option. Check the long-term return for that option Focus on five and ten year returns, not just last year and compare them with equivalent options. Understand the total cost Add together administration fees, investment fees and insurance premiums as an annual dollar figure. Comparing super is about working out which option will perform best for you. Before you jump in, it’s worth understanding what's behind the numbers so you can make decisions based on more than a headline return. Knowing where you stand is the first step A super balance tells you where you are today. Understanding how your super is invested, how it compares and whether it's aligned with your goals helps show whether you're heading in the right direction.
