Introduction: Why We Crave Complexity

In many areas of life, we associate complexity with sophistication. This belief is particularly strong in financial planning and investing, where there’s an inclination to think that the more intricate the strategy, the better the outcome. The financial industry itself often perpetuates this idea, using jargon and elaborate structures to make advice seem more valuable.

But in reality, simplicity is often the key to long-term success. Complexity can be a distraction – one that leads to costly mistakes, unnecessary stress, and poor financial outcomes. A well-structured, simple approach can often be far more effective than an overly complicated one.

Simplicity in Financial Planning

When it comes to financial planning, complexity can lead to inaction. Many people feel overwhelmed by the sheer volume of financial decisions they need to make – saving, investing, tax planning, superannuation, estate planning, and so on. If a financial plan is too complicated, clients may struggle to follow it, leading to inconsistent execution or complete abandonment.

For example, consider two approaches to retirement savings:

1. A complex plan that involves intricate tax strategies, multiple investment accounts, and a long list of rules to follow.
2. A simple plan that focuses on regularly contributing to superannuation, holding a diversified portfolio, and avoiding emotional decision-making.

While the first approach may appear more refined, the second is easier to stick to and often leads to better long-term results simply because it removes unnecessary hurdles.

The Downside of Complexity in Investment Strategies

Many investors assume that a complex investment strategy must be superior. Fund managers and financial institutions reinforce this by offering products with complicated structures, promising better risk-adjusted returns. But research consistently shows that simpler strategies – like a well-diversified, low-cost portfolio – often outperform high-fee, actively managed investments over the long term.

Take hedge funds, for example. Many hedge funds use elaborate trading strategies and charge high fees, yet studies have found that the average hedge fund struggles to beat a simple index fund after fees are considered. The same applies to investors who chase yesterday’s winning stocks, thematic funds, or excessive diversification – complexity adds layers of decisions, costs, and risks without necessarily improving results.

Research Evidence: Why Simplicity Works

A 2016 study by Jason Hsu, Ph.D., and John West, CFA, titled The Confounding Bias for Investment Complexity, explores why investors and financial professionals have an inherent bias toward complex strategies, despite evidence that simpler approaches often deliver better outcomes.

Key findings from the study include:

• Many investors and financial professionals assume that complexity is necessary to outperform the market, leading to higher fees and more intricate strategies.
• Research shows that simple, low-turnover investment strategies perform just as well as complex, high-turnover strategies on a pre-fee basis – meaning that, after accounting for costs and taxes, simpler approaches often have an advantage.
• Complexity encourages performance chasing, leading investors to frequently switch strategies based on short-term results, ultimately reducing long-term returns.
• Simplicity leads to better investor behaviour, as a clear and understandable strategy makes it easier for investors to stay the course during market volatility.

The study draws a fishing analogy: While sophisticated fishing lures appear more effective, a simple wooden lure (a cedar plug) consistently catches more tuna. Similarly, in investing, unnecessarily complex strategies often fail to deliver superior results compared to straightforward, well-structured approaches.

Behavioural Finance: Why Simple Strategies Work Better

A key reason simplicity works is human behaviour. Complexity in investing often leads to decision fatigue, overtrading, and panic-driven actions – three of the biggest killers of long-term wealth.

Consider these common behavioural pitfalls:

• Overthinking investment decisions – Investors often seek the “perfect” strategy, delaying action for years instead of just getting started.
• Panic-selling during downturns – A complex portfolio that isn’t well understood is harder to stick with during volatile markets.
• Chasing trends – The temptation to keep tweaking a strategy based on market trends often leads to worse performance.

One of Warren Buffett’s simplest pieces of advice is that most investors should just buy an index fund and hold it. This advice, while simple, works because it prevents emotional decision-making and keeps costs low.

The Role of a Good Financial Advisor

A good financial advisor simplifies complexity rather than adding to it. The best advice isn’t about making things sound sophisticated – it’s about helping clients focus on what truly matters.

This is especially true for investment selection, tax planning, and structuring finances for long-term success. An advisor’s role isn’t to create unnecessary layers of strategy but to align the plan with the client’s real goals in a way that they can understand and execute.

For example, a retirement strategy should focus on ensuring a reliable income stream, not just on maximising tax efficiency at the expense of simplicity. While tax planning is important, a strategy so complex that it leads to confusion or mismanagement can backfire.

Practical Tips for Keeping It Simple

If you’re looking to simplify your financial strategy, consider these practical steps:

• Automate savings and investing – Set up automatic contributions to superannuation and investment accounts so you don’t have to think about it.
• Stick to a core investment philosophy – Focus on time in the market rather than trying to time the market.
• Avoid unnecessary complexity in portfolios – Holding too many funds or constantly tweaking allocations adds layers of confusion and costs.
• Measure success based on long-term goals – Instead of constantly checking your portfolio, focus on whether you’re making progress toward financial independence.

Conclusion: Simple Doesn’t Mean Easy – But It’s More Effective

Simplicity in financial and investment planning doesn’t mean doing nothing. It takes discipline to avoid distractions, stay the course, and resist the urge to overcomplicate things.

The key takeaway? Complexity should only be added when it genuinely adds value. If a simpler strategy achieves the same or better results, it’s the better option.
