What is Portfolio Diversification?
Diversification is the concept of taking exposure to a range of different assets both to seek different return drivers and to help reduce risks by limiting exposure to any one asset While often discussed in a cross asset class context, diversification may also offer benefits within asset classes. Within equities, some potential opportunities to diversify include:
- Broadening geographic exposure
- Exploring different sectors
- Investing in themes
- Considering companies of different sizes
Broader Geographic Exposure
Many investors have a natural bias towards investing in the equity market of their home country. While this can make sense due to greater knowledge of local economic and market conditions and potential currency risk when investing abroad, it may mean missing out on opportunities occurring elsewhere.
We see this spread of opportunities across countries reflected in the range of returns of the 47 country indices that make up the MSCI All Country World Index, as shown in the next chart. In each of the last 10 years, there were countries that experienced drawdowns as well as those that performed strongly.
This range of performances can reflect countries experiencing differing economic conditions at different times, varying sensitivity to changes in global demand, and country idiosyncratic shocks, among other factors.

MSCI Saudi Arabia data from Jan 2019. Performance range reflects the range of performances within which all country index returns for that year fell. See glossary for more information. *2024 is YTD to Sep 2024.
Diversifying equity exposure across countries can potentially lead to higher risk adjusted returns. The next chart shows an example of this with historical risk adjusted returns (measured by Sharpe Ratio), for single country exposure (Germany) compared to regional equity exposure (Europe), compared to developed markets equity exposure, over the last 10 years.

Explore Different Sectors
Within countries, different sectors of the economy may face different headwinds as well as differing drivers of returns at different times. Demand for the products and/or services of any one sector may not move in sync with the overall ups and downs of the domestic economy.
The chart below shows the range of performance for different industrial sectors in the United States for each of the last 10 years.
Historical Performance of S&P 500 Sectors

Different sectors also represent different proportions of different countries’ economies. For example, the S&P 500 index of US equities has a 29% weight to the Information Technology sector, compared to around 1% in the UK’s FTSE 100 index or in Brazil’s Ibovespa index1. In this way, an investment in a country may implicitly carry more, or less, exposure to any one industrial sector.
Invest In Themes
Investment themes aim to take exposure to specific business areas that may be beneficiaries of structural changes in the economy and potentially experience growth. For example, they may be as specific as “cybersecurity" or as broad as “aging demographics”, and typically encompass multiple areas of a value chain, cutting across traditional industrial sectors.
The example below illustrates how some themes have seen abnormal growth, but the adoption of themes can be rapid, hard to time, and they may also not take off as anticipated. As themes can offer exposure to sources of risk and return beyond geographies and industrial sectors, taking exposure to multiple different themes may be beneficial.

Global Semiconductors is the S&P Global Semiconductors Index. US Equities is the S&P 500 Index. Global Equities is the MSCI ACWI Index. Periods cover trough to peak performance of themes within a maximum 6 year window. US Internet Commerce series starts in Aug 1997. All indices reflect index price return only.
Companies Of Different Sizes
Smaller companies, as measured by market capitalization, tend to have different characteristics to companies of larger sizes, and can thus offer exposure to different risks as well as sources of return.
Smaller companies tend to be less established in their industries, and often sell a more concentrated range of goods or services in a smaller geographic area compared to their larger peers. This may result in their having greater sensitivity to changing economic conditions.
This increased sensitivity may be one reason why smaller companies have historically seen outperformance and higher volatility compared to their larger peers in the first year following a recession.

In the US, small caps outperformed large caps in the year after 14 of 16 US recessions since 1926 (88% of the time)2. In Europe, small caps outperformed large caps in the year after 3 of the 4 Euro area recessions since inception of the bloc in January 19993.
While investing in smaller companies has historically come with increased levels of risk, their differentiated return drivers may increase diversification within a portfolio.
Conclusion
Companies operating in different geographic locations, industrial sectors, or business areas as well as those of differing sizes all face a combination of the same and unique propellants and challenges.
Investing in equities with a view to diversifying across these can lead to exposure to more areas of a broader market, and so a greater variety of return drivers, as well as spreading risks. Nevertheless, investors shouldn’t attempt to invest in every opportunity but instead should take a balanced approach to investing across a manageable number of investments that offer exposure to a diversified opportunity set.
