The Importance of Evidence Based Investing

The Importance of Evidence Based Investing

With more people than ever before turning their hand to investing, supporting people in making responsible financial decisions is of high priority

When choosing to build an investment portfolio, strategy is a key consideration to be made, as your choice of investment approach can have a huge impact on the long and short-term success or failure of your investments. In addition, the investment landscape can be highly overwhelming for the new investor, making it challenging to select the right approach for you.

What is Evidence Based Investing? 

Evidence based investing is an investment strategy rooted in scientific data, whereby all investment decisions are guided by relevant research and reliable sources. Evidence based investors work to stay informed regarding long-term observations of markets and how they work, based on the understanding that this research offers their investments a more secure foundation.

Often, other types of investors find themselves attempting to predict the future, chasing peaks for seemingly high-value stocks. This is commonly referred to as ‘active investing’, whereby a fund manager will try to ‘beat’ the stock market’s average return, guessing the right time to buy and sell certain bonds, shares and other assets based on what appears to be happening in the market. Evidence based investment takes a different approach in acknowledging that financial markets are efficient, and making accurate predictions of this kind can be difficult. Evidence based investing typically includes investing in low-cost index funds or exchange-traded funds that track market indexes.

When it comes to Evidence-based investing, the selection of data sources is of vital importance. The sources that are relevant to your investment will likely be contingent on the areas you wish to invest in. Valuable sources of information might include government agencies, financial statements, company representation, analyst reports and stockbrokers to name a few.

Things to Consider Before Building an Evidence Based Investment Portfolio.

News is Not Always Accurate

When collecting evidence and data to inform your investments, it is recommended that investors be mindful of their reference to mainstream news outlets within their research, as to avoid data impacted by biases or inflated figures. It is always important to back your research up with credible sources.

Emotions and Investments Don’t Mix

Being mindful of emotional investing is another key area of focus when it comes to evidence-based strategy. An investor mustn’t allow investments that seem appealing to impact their rationality. Investment decisions should not be based on a fear of missing an opportunity – impulse investments pose a larger financial risk than those backed by data.

Tap into the Right Sources

As previously mentioned, selecting the right sources is an essential part of evidence based investing. Many government agencies have public resources full of useful information and investment data. In addition, the support of industry experts such as Hansford Bell can offer you peace of mind that your investment decisions are supported by the relevant data. Further still, it is even possible to hire a research analyst to collect data for you.

Look Beyond the Numbers

While numbers do tell us something about the value of stock, there may be more pieces to the puzzle. Evidence based investment strategies encourage investors to look beyond the numbers and seek out any hidden issues or concerns related to a given investment.


As will many financial matters, time is key to evidence based investing. An evidence based portfolio is a long-term strategy that will require an investor to be patient and learn from their mistakes. Again, seeking advice from industry professionals such as Hansford Bell can offer guidance and reassurance for an investor at any point on their investing journey.

Benefits of Evidence Based Investing

Build a more secure portfolio

A key benefit of evidence-based investing is that it allows investors to build a secure and stable financial future that grants them greater access to their long-term financial goals as investors. Taking this longer-term approach allows investors to benefit from compounding over time. The long-term experience granted by this approach is also likely to refine the investor’s knowledge of which investments pose the longest-term benefits.

Freedom from Fees

The slower and more considered pace of evidence-based investing also frees an investor from the high fees and hidden costs associated with active management and trading. These lower costs sometimes mean that evidence-based investing generates higher returns

Fewer losses from impulse investments

As previously noted, many alternative methods of investment require investors to detect peaks and troughs in their target markets, investing at what they consider to be the ‘ideal’ time. The ever-changing status of the stock market can generate pressure around these choices that may ultimately result in an ill-considered investment. The numerous stages of research required as a part of an evidence-based strategy reduce an investor’s susceptibility to making investments based on these heightened emotional states.

Reduced Stress

Similarly, while active investment styles require an investor to make frequent high-risk decisions within a limited time frame, evidence based investments free investors from the stress of these high-pressure scenarios – offering benefits to wider mental wellbeing.
