Why the “most efficient” investment path isn’t always the right one

When it comes to investing, there’s a strong focus on efficiency. 

Low fees, passive investing, and broad diversification are often presented as the smartest long-term approach. In many situations, those principles have merit. 

Over the years I’ve come to believe that the “most efficient” investment strategy on paper is not always the most suitable strategy in practice. Markets evolve. Economic conditions change. Investor behaviour shifts. Sometimes, a portfolio designed purely for efficiency can struggle when the environment changes around it.

Investing isn’t just about cost 

One of the biggest misconceptions I see is the idea that lower cost automatically means better value. Cost matters, of course, but investing should never be judged on fees alone. 

The real question should be: 

“Is this strategy likely to help achieve the outcome I actually want?” 

What you “actually want” is personal. It might be building a property portfolio, having the freedom to travel, setting up your children for the future, or retiring comfortably with the lifestyle you want. In recent years, markets have become increasingly influenced by factors like inflation, geopolitical uncertainty, interest rate changes, and economic disruption. During these periods, simply owning “the market” through passive exposure may not always provide the balance or resilience investors expect. 

That doesn’t mean passive investing is wrong – it simply means no single approach works perfectly in every market environment. 

Why diversification can sometimes fall short 

The old adage of investing is ‘don’t put all the eggs into one basket’ – that is diversification.  

Diversification remains incredibly important, but not all diversification is created equal. 

Many portfolios appear diversified because they hold hundreds or even thousands of investments. However, those investments can still be heavily exposed to the same underlying economic risks. 

We saw this during several major market events over the past two decades, where entire sectors or regions moved together despite investors believing they were adequately diversified. 

That’s one reason I believe there is value in looking beyond traditional index investing and considering evidence-based multi-factor investing approaches. 

Looking at different drivers of return 

Rather than relying solely on market-cap weighting, multi-factor investing focuses on different characteristics that have historically influenced long-term returns. 

These can include factors such as: 

• Value  

• Profitability  

• Momentum  

• Company size 

The goal is not to predict markets or chase short-term performance. 

Instead, it’s about building portfolios that can adapt more effectively across a wider range of market conditions. 

Different factors tend to perform better at different times. By combining them thoughtfully, investors may reduce reliance on any single market outcome. 

The risk of standing still 

One of the most difficult parts of investing is knowing when to reassess a strategy. 

It’s natural for investors to avoid change during uncertain periods. Although in my experience, staying committed to a strategy that no longer fits the environment can sometimes create greater long-term risk than making a measured adjustment. 

History gives us plenty of examples of this: 

• The dot-com crash  

• The Global Financial Crisis  

• The COVID-19 market disruption  

In each case, many investors remained heavily concentrated in areas that had performed well previously, only to discover those conditions had changed significantly. 

Markets are forward-looking, and investment strategies should be too. 

Building portfolios for the future 

I believe investing should be dynamic, thoughtful, and evidence based. 

Evidence-based investing means making investment decisions using long-term market research and proven drivers of return, rather than relying on speculation, trends, or emotion. This can include factors like value, profitability, and diversification across different market conditions to help build more resilient portfolios over time. 

It’s not about constantly reacting to markets. It’s about applying research-backed strategies in a way that aligns with an investor’s goals, risk tolerance, and long-term objectives. 

That’s where good financial advice can make a real difference, helping investors cut through the noise and build portfolios designed for long-term outcomes, not short-term headlines. 

Final thoughts 

Efficiency matters, costs matter and diversification matters. 

Successful investing is about more than simply finding the cheapest or most straightforward option. The right investment approach should reflect the individual behind it, including their goals, timeframes, tolerance for risk, and what they ultimately want their money to achieve. 

There is no one-size-fits-all approach to investing. The right strategy depends on your goals, financial position, and tolerance for risk, which can make knowing the best path forward difficult on your own. 

That’s where good advice can make a real difference. Our focus at Apex Advice, is on helping clients cut through the noise to build investment portfolios that are resilient, adaptable, and aligned with what they want to achieve long term. 

Because sometimes the “most efficient” path on paper isn’t necessarily the one most likely to deliver the outcome that matters most to you.
