Evidence-Based Investing: Why Research Matters in Portfolio Design
Financial planning has changed greatly over the last 40 years.
It once centred on arranging a product. Then the emphasis often moved towards selecting investments. Today, at its best, financial planning starts somewhere much more important: with the person.
Ifamax was established more than 20 years ago around that principle.
Before discussing investments, we want to understand what matters to you. Your hopes for the future, the people you want to support, the work you enjoy, when you may want to retire and the choices you would like to have along the way.
The role of a financial planner is not simply to deal with paperwork or recommend an investment. It is to bring the different parts of your financial life together, step in when circumstances change and help keep your plan moving in the right direction.
That is why investment conversations usually come after we have understood the wider plan.
A Simple, Disciplined Investment Approach
No one can consistently predict what markets will do next.
There will always be confident views about which country, sector or company will perform best. Sometimes those views will be right. The difficulty is knowing which ones in advance and, just as importantly, knowing when to change course.
Our approach is therefore designed to be disciplined rather than reactive.
We focus on broad diversification, sensible costs and a long-term perspective. We do not try to chase the latest investment theme or make sweeping changes because of short-term headlines.
Simple does not mean simplistic. It means having a clear process, understanding why each part of a portfolio is there and avoiding unnecessary complexity.
Passive Investing With an Active Twist
Investment discussions are often presented as a choice between two opposing approaches: active or passive.
A passive fund generally aims to track the return of a market or index. An active manager makes decisions about which shares, bonds or other investments to hold in the hope of doing better than that market.
Neither approach is automatically right or wrong.
Our portfolios use a systematic, evidence-based approach. They are broadly diversified and low cost, but they are not designed simply to mirror a market-capitalisation-weighted index.
Research over many decades has identified characteristics that have historically been associated with higher expected returns over the long term. These include exposure to companies that appear attractively valued, smaller companies and, where appropriate, selected emerging-market and property exposures.
This means our portfolios may look different from a standard global market index. That difference is deliberate and based on research rather than a view about which company or manager will be successful next year.
Evidence Is Not a Guarantee
It is important to be clear about what an evidence-based approach can and cannot do.
It does not guarantee that a portfolio will outperform a particular index. There will be periods when it does not.
For example, when a small group of large growth companies or a particular sector has an exceptionally strong run, a more diversified portfolio with less exposure to those areas may lag behind. Equally, the areas that have been out of favour can recover strongly, often when least expected.
The purpose of the approach is not to pursue the highest possible return in every market environment. It is to give clients a well-diversified, repeatable investment strategy with a higher probability of supporting their long-term financial plan.
That requires patience, particularly when markets make one approach appear obviously better than another for a time.
Why We Do Not Rely on Finding the “Best” Manager
There will always be individual fund managers, concentrated portfolios and tactical strategies that produce excellent returns over a period of time.
The challenge is identifying in advance which ones will continue to do so, after costs, and through different market conditions.
A small number of active managers will add value over time. Many will not. Distinguishing long-term skill from a favourable period of markets can take many years.
This is why we do not build a portfolio around the belief that we can repeatedly identify tomorrow’s best-performing manager or predict the next winning investment theme.
Instead, we seek to control the things we can control: diversification, costs, tax efficiency, risk, regular rebalancing and a disciplined process.
Investment Returns Are Only One Part of the Picture
Good investment returns matter. But they are not the whole story.
What matters is the return you keep and how effectively it supports your life.
For someone building wealth, this may mean making full use of pensions, ISAs and other tax-efficient investment opportunities. For someone approaching or living in retirement, it may mean planning withdrawals carefully, managing tax across different accounts and ensuring that investment risk remains appropriate.
There is also the human side of investing.
When markets fall, it can be tempting to sell. When a particular area is performing strongly, it can be tempting to chase it. Both decisions can feel sensible at the time, but they can damage a carefully built long-term plan.
One of the most valuable roles we can play is to provide perspective during those moments: revisiting the purpose of the portfolio, explaining what is happening and helping clients remain focused on their wider goals.
Portfolio Design Should Support Your Plan
As financial planners in Bristol, we believe investments should serve the financial plan, not become the plan itself.
A portfolio should reflect the income you may need, the risks you are comfortable taking, the time available and the life you want your money to support.
At Ifamax, we combine evidence-based investing with financial planning, tax-efficient strategies and ongoing support. The aim is not to promise the best return in every year.
It is to provide a clear, well-researched investment strategy that can support your plans through changing markets and changing stages of life.
