The majority of economists think that investors won’t receive the same strong returns from the markets in 2022 as they did in the previous three years, and some even foresee a correction. Diversification is one of the key remedies against market swings and crises, but how precisely and how deeply a portfolio should be diversified is still up for debate. This article explains what the science says about optimal diversification and what an investor must consider before a storm hits.
Why is it important to diversify?
The non-market risk associated with a certain firm is decreased by 40% if you have two companies in your portfolio, by 80% if you have eight, and by 99% if you have one hundred and twenty-eight. The US fund LTCM went bankrupt in 1998 as a result of fake diversity, proving that a portfolio with a lot of securities is not necessarily diverse.
Lesser returns also imply lower risk. Therefore, each investor must select the ideal ratio of expected return to risk.
In a diversified portfolio, equities should react differently to different risks. The famous American economist, Nobel Prize winner Harry Markowitz, started talking about the principles of investor portfolio formation back in 1952. For example, a shortage of semiconductors would be bad for smart-phone and car makers, and good for chipmaker stocks, as the price of the product would rise.
At the same time, it should be understood that diversification will not protect against market risks to which all types of assets are exposed. In times of economic crisis, asset correlations can intensify.
Asset correlations, for instance, sharply surged during the 2015 Chinese stock market meltdown. However, the correlation dropped significantly in 2021 as investors switched to a risk-off posture. In this manner, bonds, commodity currencies (such as the Australian, Canadian, and New Zealand dollars), and commodities market assets are bought and sold in exchange for high yield bonds (US Treasuries).
While stocks and bonds are the conventional assets used to build a portfolio, a wide range of alternative investments, including real estate investment trusts, hedge funds, fine art, and precious metals, offer the chance for additional diversity.
What are the ways to diversify?
Bonds and Stocks.
The ratio of shares to bonds should be 50:50 or 25:75. If shares are overvalued, in an investor’s opinion, their proportion should be 25%, and if the value of shares falls, their proportion may increase up to 75%.
Basic principles of equities and bonds ratio are described in B. Graham’s work “The Intelligent Investor”.
In addition, other famous investors advice to increase the share of bonds in their portfolios diver in case of economic recession risks.
The “death” of the 60/40 portfolio.
Unfortunately, the traditional 60/40 portfolio diversification is no longer so relevant. More and more investors are abandoning this strategy as central banks are raising interest rates to fight inflation, which is bad for both stocks and bonds. This, as evidenced by the S&P 500 Index falling 2.25% since the start of 2022 and the Bloomberg Global Aggregate Index falling 0.36%.
Investors are also concerned about the total number of stocks in the portfolio. However, here too there is no unequivocal opinion, and various researchers suggest different numbers from 7 to 300 shares.
In market research, the size of a well-diversified portfolio has increased, probably due to lower commission costs. Among other things, there has been an increase in market volatility and, consequently, an increase in unsystematic risks. For developed markets, the number of stocks in the portfolio is greater than for emerging markets, because in the case of the former there is more choice.
The drawbacks of investing in a large number of companies include the time required to thoroughly research each firm and the dearth of viable investment opportunities.
Due to stocks’ superiority over bonds over the long term, it is typically suggested for retirees who are younger to invest more money in equities. As a result, equities often account for 70% to 100% of an investment portfolio for retirement.
However, the portfolio often changes more in favor of bonds as the investor gets closer to retirement age. While this adjustment would lower predicted returns, it will also lower portfolio volatility as the retiree starts to use his investments to generate a retirement check.

The political and economic risks of a single country in a portfolio can be reduced by diversifying assets across nations. Examples include a 21.64% decline in the MSCI China index of Chinese companies in 2021, a 2.22% decline in the MSCI EM emerging markets index, and a 19% increase in the ACWI index, which mixes 23 developed and emerging countries.
The consensus started to erode in the 1990s as a result of growing correlation brought on by globalization and the integration of global markets.
First, a lot of organizations have gone global and are expanding both domestically and internationally, so by investing in them, investors are already obtaining a wide range of nationalities. Second, there are “no safe havens in the storm” as a result of strong economic and financial linkages.
For example, the 2008 crisis that began in the U.S. led to the collapse of stock markets around the world.
However, some of the advantages of diversification continue since enterprises with headquarters outside of the United States, particularly in emerging economies, may run differently.
According to Wall Street Journal columnist Jason Zweig, a global investor should follow a country’s weight in the MSCI ACWI index. The U.S. made up 61.3 percent of the index’s weight as of the end of December 2021, while China made up 3.6 percent. Tenths of one percent is what Russia and other developing nations represent.
Investor tip: A useful way to find the ideal split between stocks and bonds is to subtract your age from 100. This number is the percentage you could allocate to stocks – for example, a 27-year-old could invest 73% of their money in stocks and the other 27% in bonds.
Sectors and Industries
Stocks can be categorized by sector or industry, and investing in the stocks or bonds of businesses operating in many industries offers significant industry diversification.
For instance, the S&P 500 index includes equities from businesses operating in 11 different sectors:
- Communication Services
- Consumer Staples
- Consumer Discretionary
- Energy
- Technology
- Financials
- Industrials
- Materials
- Health Care
- Real Estate
- Utilities
Companies in the real estate and finance industries suffered large losses during the Great Recession of 2007–2009. In contrast, there weren’t as many losses in the utilities and healthcare sectors. Industry diversification (portfolio diversification) is yet another essential strategy for reducing investment risk.
Although the effectiveness of diversification is compared to diversification by country, the latter strategy is better protected in times of crisis.
In terms of performance over the past 25 years, investors have benefited more from diversification by sector. As with the geographic strategy, investors should also pay attention to the percentage of each sector in the MSCI ACWI index.

You can also find growth and value diversification by purchasing the stocks or bonds of businesses at various phases of their corporate lifecycles. The risk and return characteristics of newer, rapidly expanding businesses differ from those of older, more firmly established businesses.
Growth firms are businesses that are generating sales, profits, and cash flow quickly. These businesses typically trade at greater prices than the market as a whole in relation to reported earnings or book value. Their quick expansion is utilized to support the high valuations.
Value businesses are those with slower growth rates. They typically belong to more seasoned businesses or organizations in specific sectors, such utilities or the financial sector. In addition to having slower growth than the market as a whole, these companies often have lower values.
Some people believe that value companies outperform growth companies in the long run. At the same time the current market is an example of how growth companies can outperform value companies.
Investment funds
With mutual funds, diversifying your portfolio is quite simple and quite effective. In fact, one target-date pension fund allows an investor to create a well-diversified portfolio. The so-called three-fund strategy, which uses just three index funds, can provide impressive diversity.
Perhaps a certain combination of investments will work for a child’s college education, but for long-term goals such as estate planning or retirement, it may not be enough.
Bottom Line 🏁
It might appear that diversification would be simple to achieve with so many investments to pick from, but that is only partially true. Choosing wisely is still a need for investors. Additionally, over-diversifying your portfolio has the potential to hurt your returns. 20 equities are generally considered to be the ideal quantity for a diversified equity portfolio by financial professionals. Considering this, purchasing four large-cap mutual funds or 50 individual stocks could be detrimental rather than beneficial.
Regardless of your capabilities or choice of strategy, remember that there is no one-size-fits-all model that will work for every investor. Consider your personal goals, financial strength, risk tolerance, and experience-all of which combine to determine the best mix of diversification portfolios. If you don’t have enough experience, you can always have your funds allocated by experienced professionals. (Here it can be an algo trading or a broker).
It is crucial to remember that the relationship between various assets could alter over time. Furthermore, diversification only offers protection from non-market risks because, in times of world crises, asset correlations build and the only way to avoid a decline is to wait it out.
