ETF Diversification: How Many ETFs Should You Invest In?

Investing in Exchange-Traded Funds (ETFs) has become increasingly popular over the years due to their flexibility, diversification benefits, and cost-effectiveness. However, one of the most common questions investors face is how many ETFs to invest in. While there is no one-size-fits-all answer, this article will provide you with a comprehensive guide to help you determine the ideal number of ETFs for your investment portfolio.

Understanding ETFs and Diversification

Before we dive into the number of ETFs to invest in, it’s essential to understand what ETFs are and how they can help with diversification. ETFs are traded on a stock exchange, like individual stocks, and track a specific index, sector, or asset class. They offer investors a way to gain exposure to a broad range of assets, such as stocks, bonds, commodities, or currencies, with a single investment.

Diversification is a key benefit of ETFs, as they allow investors to spread their risk across different asset classes, sectors, and geographic regions. By investing in a diversified portfolio of ETFs, investors can reduce their exposure to individual stock or sector risk and increase their potential for long-term returns.

The Importance of Core-Satellite Investing

One popular approach to building an ETF portfolio is the core-satellite strategy. This involves dividing your portfolio into two parts: a core holding and satellite holdings. The core holding is typically a broad-based ETF that tracks a major index, such as the S&P 500 or the Total Stock Market. This provides the foundation of your portfolio and represents the largest portion of your assets.

The satellite holdings are smaller, more specialized ETFs that track specific sectors, industries, or asset classes. These ETFs are used to add diversification and potentially increase returns, but they should not make up the majority of your portfolio.

Benefits of Core-Satellite Investing

The core-satellite approach offers several benefits, including:

  • Simplified portfolio management: By dividing your portfolio into core and satellite holdings, you can simplify your investment decisions and reduce the number of ETFs you need to monitor.
  • Improved diversification: The core-satellite approach allows you to diversify your portfolio across different asset classes and sectors, reducing your exposure to individual stock or sector risk.
  • Increased potential for returns: By adding satellite holdings to your portfolio, you can potentially increase your returns and enhance your overall investment performance.

How Many ETFs Should You Invest In?

So, how many ETFs should you invest in? The answer depends on several factors, including your investment goals, risk tolerance, and time horizon. Here are some general guidelines to consider:

  • Simple portfolios: If you’re just starting out or prefer a simple investment approach, you may want to consider investing in just 2-3 ETFs. This could include a broad-based core holding and one or two satellite holdings that track specific sectors or asset classes.
  • Moderate portfolios: If you’re looking for a more diversified portfolio, you may want to consider investing in 4-6 ETFs. This could include a core holding and several satellite holdings that track different sectors, industries, or asset classes.
  • Complex portfolios: If you’re an experienced investor or have a high-risk tolerance, you may want to consider investing in 7 or more ETFs. This could include a core holding and several satellite holdings that track specific sectors, industries, or asset classes.

Key Considerations

When determining how many ETFs to invest in, there are several key considerations to keep in mind:

  • Diversification: Make sure your portfolio is diversified across different asset classes, sectors, and geographic regions.
  • Risk tolerance: Consider your risk tolerance and adjust your portfolio accordingly. If you’re risk-averse, you may want to invest in fewer ETFs or focus on more conservative holdings.
  • Time horizon: Consider your time horizon and adjust your portfolio accordingly. If you have a long-term time horizon, you may be able to take on more risk and invest in a more diversified portfolio.
  • Fees and expenses: Consider the fees and expenses associated with each ETF and make sure you’re not overpaying for your investments.

Example Portfolios

Here are some example portfolios to illustrate the different approaches:

  • Simple portfolio:
    • 40% Vanguard Total Stock Market ETF (VTI)
    • 30% iShares Core U.S. Aggregate Bond ETF (AGG)
    • 30% Vanguard Total International Stock Market ETF (VXUS)
  • Moderate portfolio:
    • 30% Vanguard Total Stock Market ETF (VTI)
    • 20% iShares Core U.S. Aggregate Bond ETF (AGG)
    • 20% Vanguard Total International Stock Market ETF (VXUS)
    • 15% iShares North American Tech ETF (IGM)
    • 15% iShares Core S&P 500 ETF (IVV)
  • Complex portfolio:
    • 20% Vanguard Total Stock Market ETF (VTI)
    • 15% iShares Core U.S. Aggregate Bond ETF (AGG)
    • 15% Vanguard Total International Stock Market ETF (VXUS)
    • 10% iShares North American Tech ETF (IGM)

    • 10% iShares MSCI EAFE ETF (EFA)
    • 10% iShares MSCI Emerging Markets ETF (EEM)

Conclusion

Determining how many ETFs to invest in depends on several factors, including your investment goals, risk tolerance, and time horizon. By considering these factors and following the core-satellite approach, you can build a diversified portfolio that meets your needs and helps you achieve your investment objectives. Remember to keep your portfolio simple, diversified, and aligned with your goals, and don’t be afraid to adjust it as your needs change over time.

What is ETF diversification and why is it important?

ETF diversification is a strategy used by investors to spread their investments across different asset classes, sectors, and geographic regions to minimize risk and maximize returns. By investing in a variety of ETFs, investors can reduce their exposure to any one particular market or sector, which can help to reduce the overall risk of their portfolio.

A diversified ETF portfolio can also help to increase potential returns by capturing growth opportunities in different markets and sectors. By spreading investments across different asset classes, investors can benefit from the performance of different markets and sectors, which can help to increase overall returns. Additionally, ETF diversification can help to reduce the impact of market volatility, as losses in one market or sector can be offset by gains in another.

How many ETFs should I invest in for optimal diversification?

The ideal number of ETFs for optimal diversification depends on various factors, including the investor’s risk tolerance, investment goals, and time horizon. Generally, a portfolio with 5-10 ETFs can provide adequate diversification, but this number can vary depending on the specific ETFs and the investor’s overall investment strategy.

It’s also important to consider the overlap between different ETFs and the overall asset allocation of the portfolio. For example, if an investor has two ETFs that track the same index, it may not provide additional diversification benefits. On the other hand, if an investor has a mix of ETFs that track different asset classes, sectors, and geographic regions, it can provide a more diversified portfolio.

What are the benefits of investing in a small number of ETFs?

Investing in a small number of ETFs can provide several benefits, including lower costs, reduced complexity, and easier portfolio management. With fewer ETFs, investors can reduce their overall expense ratio, as they will have fewer management fees to pay. Additionally, a smaller number of ETFs can make it easier to monitor and adjust the portfolio, as there are fewer holdings to track.

Another benefit of investing in a small number of ETFs is that it can help to reduce the risk of over-diversification. When investors spread their investments too thinly across too many ETFs, it can lead to a lack of conviction in any one particular investment, which can result in lower returns. By investing in a smaller number of ETFs, investors can focus on their highest-conviction ideas and avoid over-diversification.

What are the risks of investing in too many ETFs?

Investing in too many ETFs can lead to several risks, including over-diversification, increased costs, and reduced returns. When investors spread their investments too thinly across too many ETFs, it can lead to a lack of conviction in any one particular investment, which can result in lower returns. Additionally, a large number of ETFs can increase the overall expense ratio, as investors will have more management fees to pay.

Another risk of investing in too many ETFs is that it can make it more difficult to monitor and adjust the portfolio. With too many holdings, it can be challenging to keep track of each ETF’s performance, which can make it harder to make informed investment decisions. Additionally, a large number of ETFs can increase the risk of overlap, where investors may inadvertently hold multiple ETFs that track the same index or sector.

How can I determine the right number of ETFs for my portfolio?

To determine the right number of ETFs for your portfolio, you should consider your investment goals, risk tolerance, and time horizon. You should also consider the overall asset allocation of your portfolio and the specific ETFs you are considering. It’s also a good idea to consult with a financial advisor or investment professional to get personalized advice.

Another way to determine the right number of ETFs is to consider the core-satellite approach. This approach involves investing in a core portfolio of 2-3 ETFs that provide broad diversification, and then adding satellite ETFs that provide more targeted exposure to specific markets or sectors. This approach can help to reduce the overall number of ETFs in the portfolio while still providing adequate diversification.

Can I use a single ETF to achieve diversification?

Yes, it is possible to use a single ETF to achieve diversification. There are many ETFs that track broad market indexes, such as the S&P 500 or the MSCI ACWI, which can provide exposure to a wide range of stocks and sectors. These ETFs can be a good option for investors who want to simplify their portfolio and reduce costs.

However, it’s worth noting that even with a single ETF, it’s still important to consider the overall asset allocation of the portfolio and the investor’s risk tolerance. For example, if an investor is heavily concentrated in a single ETF that tracks a specific sector or market, it may not provide adequate diversification. Additionally, a single ETF may not provide the same level of diversification as a portfolio with multiple ETFs that track different asset classes and sectors.
