Importance of Diversification

Importance of Diversification

Diversification is a technique that reduces risk by allocating investments among various financial instruments, industries, and other categories. It aims to maximize returns by investing in different areas that would each react differently to the same event.

Most investment professionals agree that, although it does not guarantee against loss, diversification is the most important component of reaching long-range financial goals while minimizing risk. Here, we look at why this is true and how to accomplish diversification in your portfolio.

Different Types of Risk

Investors confront two main types of risk when investing. The first is undiversifiable, which is also known as systematic or market risk. This type of risk is associated with every company. Common causes include inflation rates, exchange rates, political instability, war, and interest rates. This type of risk is not specific to a particular company or industry, and it cannot be eliminated or reduced through diversification—it is just a risk investors must accept.

Systematic risk affects the market in its entirety, not just one particular investment vehicle or industry.

The second type of risk is diversifiable. This risk is also known as unsystematic risk and is specific to a company, industry, market, economy, or country. It can be reduced through diversification. The most common sources of unsystematic risk are a business risk and financial risk. Thus, the aim is to invest in various assets so they will not all be affected the same way by market events.

Why You Should Diversify

Let’s say you have a portfolio of only airline stocks. If it is announced that airline pilots are going on an indefinite strike and that all flights are canceled, share prices of airline stocks will drop. That means your portfolio will experience a noticeable drop in value.

If, however, you counterbalanced the airline industry stocks with a couple of railway stocks, only part of your portfolio would be affected. In fact, there is a good chance the railway stock prices would climb, as passengers turn to trains as an alternative form of transportation.

But, you could diversify even further because there are many risks that affect both rail and air because each is involved in transportation. An event that reduces any form of travel hurts both types of companies. Statisticians, for example, would say that rail and air stocks have a strong correlation.

By diversifying, you’re making sure you don’t put all your eggs in one basket.

Therefore, you would want to diversify across the board, not only different types of companies but also different types of industries. The more uncorrelated your stocks are, the better.

It’s also important to diversify among different asset classes. Different assets such as bonds and stocks will not react in the same way to adverse events. A combination of asset classes will reduce your portfolio’s sensitivity to market swings. Generally, bond and equity markets move in opposite directions, so if your portfolio is diversified across both areas, unpleasant movements in one will be offset by positive results in another.

And finally, don’t forget: location, location, location. Diversification also means you should look for investment opportunities beyond your own geographical borders. After all, volatility in the United States may not affect stocks and bonds in Europe, so investing in that part of the world may minimize and offset the risks of investing at home.

How Many Stocks You Should Have

Obviously, owning five stocks is better than owning one, but there comes a point when adding more stocks to your portfolio ceases to make a difference. There is a debate over how many stocks are needed to reduce risk while maintaining a high return.

The most conventional view argues that an investor can achieve optimal diversification with only 15 to 20 stocks spread across various industries.

Key Takeaways

  • Diversification reduces risk by investing in investments that span different financial instruments, industries, and other categories.
  • Risk can be both undiversifiable or systemic, and diversifiable or unsystemic.
  • Investors may find balancing a diversified portfolio complicated and expensive, and it may come with lower rewards because the risk is mitigated.

The Bottom Line

Diversification can help an investor manage risk and reduce the volatility of an asset’s price movements. Remember, however, that no matter how diversified your portfolio is, risk can never be eliminated completely.

You can reduce the risk associated with individual stocks, but general market risks affect nearly every stock and so it is also important to diversify among different asset classes. The key is to find a happy medium between risk and return. This ensures you can achieve your financial goals while still getting a good night’s rest.
