At IFA, portfolio diversification is key to our asset allocation strategy and fund selection process. 

Why do we put so much stock on such a concept? It's based on a wealth of academic research and scientific evidence that points to the positive attributes of portfolio diversification. From Nobel laureates such as Eugene Fama and Harry Markowitz — often referred to as the father of Modern Portfolio Theory — we know that not "betting the ranch" on a single fund or a relatively limited number of asset classes has shown to be the most prudent investing strategy over time. 

Here are four main reasons why IFA's wealth advisors stress to clients the importance of diversifying their investment portfolios:

1.) One significant reason is risk management. In other words, diversification helps to spread the risk across various assets, reducing the overall risk of the portfolio.¹ By investing in different asset classes, industries and geographical locations, investors can minimize the impact of a single investment's poor performance on the overall portfolio.¹ This is particularly crucial for long-term investors who don't try to fiddle with (i.e., actively manage) their investments and attempt to outguess stock and bond markets.

2.) Portfolio stability is another important factor, as a well-diversified portfolio is likely to be more stable over the longer-term.² The performance of different assets tends to offset each other, leading to a smoother return on investment over time.² Furthermore, diversification can enhance overall returns by exposing investors to a wider range of opportunities.³ By diversifying across different asset classes, industries and geographical locations, investors can gain exposure to attractive areas abroad that over longer periods have proven to provide higher expected returns and aren't as correlated to the domestic market.³

3.) Inflation protection can serve as another benefit of diversification, as a diversified portfolio can help protect investors from the eroding effects of inflation.⁴ Including assets that perform well during periods of inflation — such as real estate, small-cap value and international stocks — can help an IFA Index Portfolio to maintain its purchasing power for investors over the longer-term.⁴

4.) It's also worth mentioning that diversification can provide behavioral benefits by reducing the emotional impact of short-term market fluctuations.⁵ By spreading investments across a range of assets, investors are less likely to panic in response to short-term market movements, leading to better long-term investment outcomes.⁵

In conclusion, IFA's Investment Committee finds portfolio diversification to be an essential strategy for investors to manage risk, stabilize portfolio returns, enhance overall performance, protect against inflation and improve their emotional well-being. As a result, a crucial aspect of our wealth management process is to work with clients to periodically review and rebalance their portfolios to capture the benefits of diversification while maintaining an appropriate level of risk to meet each investor's unique financial situation.
