Errors in Judgment: Blunders Committed by ETF Investors Managing a Diverse International Portfolio
In the ever-evolving world of investments, Exchange-Traded Funds (ETFs) have become increasingly popular for creating global portfolios. Arne Scheehl, Head of Product Development & Engineering at Amundi, recently discussed this topic.
One common approach for investors is to include as many stocks as possible in their portfolios when creating a global portfolio. However, this approach may not always be ideal, especially when considering the Solactive GBS Global Markets All Cap USD Index, which comprises approximately 13,000 stocks. Around 11,000 of these stocks have a weight of less than 0.01%, meaning the value changes of these low-weighted stocks would barely be noticeable in the index.
While diversification in ETFs offers several advantages, over-diversification can lead to problems. ETFs inherently provide diversification by holding multiple underlying stocks or assets, lowering the risk and volatility compared to individual stocks. Global ETFs also help spread investment risks across various countries, currencies, and economies, broadening growth opportunities internationally.
However, over-diversification can lead to diminishing returns, as adding more funds or ETFs that track similar indexes or overlapping holdings may not significantly reduce risk but can increase complexity and costs. It may also cause inefficiencies such as higher commissions and expenses, making it harder to manage and keep track of, and reducing transparency. Excessive diversification in global ETFs may expose the investor to unnecessary risks related to economic, social instability, and currency creditworthiness in different countries. Some ETFs, especially very broad or niche ones, may have tracking errors which introduce additional hidden risks.
A better alternative for investors is to consolidate holdings to fewer, well-chosen ETFs that offer broad but complementary exposure. Instead of many overlapping products, focus on a core portfolio of diversified ETFs with clear, distinct strategies. This could include a mix of U.S. large-cap, developed markets, and emerging markets ETFs. Blending ETFs with selective individual stocks, if desired, could potentially improve returns while maintaining manageable risk. Understanding the underlying holdings and investment objectives of ETFs clearly is also crucial to avoid unintended overexposure to the same risks.
In summary, while ETFs provide valuable diversification benefits, over-diversification—especially in global portfolios—can lead to higher costs, complexity, and hidden risks without proportionate benefits. A focused approach of fewer, complementary ETFs tailored to investor goals is generally a better strategy. It's also important to remember that relying on a single ETF for a global portfolio can potentially lead to oversights.
The Amundi Prime All Country World ETF (WKN: ETF150/ETF151) is a one-fund solution for building a global portfolio, while the Amundi MSCI Emerging Markets UCITS ETF DR (WKN: A2ATYY) is a product for investing in emerging markets. The investment boom in recent years has made ETFs an attractive option for creating global portfolios, but it's essential to approach this strategy thoughtfully and consider the potential risks and benefits.
Investing in Exchange-Traded Funds (ETFs) can provide a beneficial, diversified approach for creating global portfolios, but over-diversification may introduce additional costs, complexity, and hidden risks without proportionate benefits. Instead, consolidating holdings to fewer, well-chosen ETFs with clear, distinct strategies could potentially enhance returns while managing risk effectively, such as a mix of finance products like the Amundi Prime All Country World ETF for a global portfolio and the Amundi MSCI Emerging Markets UCITS ETF DR for investing in emerging markets. Emphasizing technological advancements in ETF investments can help investors make informed decisions when approaching this strategy thoughtfully.
