Three different approaches to portfolio construction

Staci West 07/04/2025 in Basics

So, you want to start investing but have no idea how to actually build a portfolio? Don’t worry, you’re not alone! The good news is that there’s no one-size-fits-all approach. Your portfolio should fit you — your financial goals, your comfort with risk, and how long you plan to invest.

Think of it like putting together a meal plan. Some people like a balanced diet (a mix of everything), some prefer a high-protein approach (all about the gains), and others go all-in on their favourite foods. Investing works the same way — there are different strategies to suit different people.

In this guide, we’ll break down three of the most common portfolio construction approaches: the core-satellite approach, the 60/40 portfolio, and the all-equity portfolio. We’ll cover the pros and cons of each so you can determine which might be right for you.

Key considerations

Before diving into specific portfolio strategies, first and foremost, your tolerance to risk is key when investing. Are you comfortable with market fluctuations, or do you prefer more stability? 

A few other key factors to consider are:

  • Investment horizon – are you investing for a long-term goal (like retirement) or something shorter-term (like a home purchase in five years)?
  • Financial goals – are you looking for growth, income, or a balance of both?
  • Diversification – spreading your money across different investments can reduce risk and improve stability.

Understanding your risk profile is an essential first step in your investment journey. Your risk profile takes into account two main things: risk aversion and risk capacity. This video explains what they are, how they work together and ultimately how to determine your own personal risk profile before making your first investment.

Three popular approaches to portfolio construction

1. The core-satellite approach

The core-satellite approach combines a broadly diversified core with smaller satellite investments to enhance returns. The core is typically made up of a global equity fund, while the satellite holdings can include more specialised or higher-risk investments like emerging market funds, thematic funds, or even individual stocks.

Pros:

  • Provides a solid foundation while allowing room for personal preferences or market trends.
  • Reduces overall risk while still offering growth potential.
  • Can be tailored to different levels of risk tolerance.

Cons:

  • Requires regular management to rebalance satellite positions.
  • Can become overly complex if too many satellite investments are added.

2. The 60/40 portfolio

The 60/40 portfolio is a traditional approach that splits investments into 60% stocks (for growth) and 40% bonds (for stability). The idea is to provide a mix of high-return potential from stocks and the lower volatility of bonds.

Pros:

  • Historically has provided strong risk-adjusted returns.
  • Offers a balance between growth and downside protection.
  • Easy to implement and maintain.

Cons:

  • May not perform well in environments where bond returns are low.
  • Might be too conservative for younger investors with a long time horizon.

3. The all-equity portfolio

An all-equity portfolio consists entirely of stocks, often through diversified ETFs, funds and investment trusts. This strategy focuses purely on growth and is most suitable for those with a long-term horizon.

Pros:

  • Historically delivers the highest long-term returns.
  • Works well for younger investors who can handle market volatility.
  • No exposure to bond market risks.

Cons:

  • Can be highly volatile, with larger swings in market value — investors must be able to stomach paper losses in times of market stress.
  • Not ideal for investors who need stability or short-term liquidity.

How to choose the right approach for you 

Each portfolio strategy has its strengths and weaknesses, so the right choice depends on your situation:

  • If you want a structured yet flexible approach, core-satellite could be best.
  • If you prefer a classic, balanced portfolio, 60/40 might be the way to go.
  • If you have a long time horizon and high risk tolerance, an all-equity strategy may suit you.

It’s also important to remember that your portfolio isn’t set in stone. As your financial situation and goals change, you can adjust your asset allocation accordingly. This video will help you focus on how to set your investment goals and understand how they may evolve over time.

Our final thoughts on portfolio construction

Regardless of which approach you choose, it’s important to keep a few things in mind. The first is fees – always make sure you understand how the cost of an investment, or platform, will influence your returns over time. Secondly, it’s important to rebalance periodically, no matter which approach you take. Market movements can shift your asset allocation, so review your portfolio at least once a year. And finally, stay diversified, spread your investments across different asset classes and geographies.

Building a solid investment portfolio doesn’t have to be complicated. By understanding different portfolio construction strategies and aligning them with your personal risk tolerance, time horizon, and financial goals, you can create a portfolio that works for you. 

The most important thing is to start investing and stay consistent — over time, your portfolio will grow, and so will your confidence as an investor.
