When Diversification Fails: This 11.3% Dividend Has A Huge Hidden Cost

While broad diversification is generally considered a sound investment strategy, the article argues that over-diversification can lead to underperformance, citing the Clough Global Opportunities Fund (GLO) as an example of a fund to avoid despite its apparent diversification and high yield of 11.3%. Instead, the author suggests a combination of the Nuveen S&P 500 Dynamic Overwrite Fund (SPXX), yielding 7.3%, and the PIMCO Dynamic Income Fund (PDI), yielding 14.1%, as a more effective approach to diversification, providing a 10.7% average dividend and strong returns by pairing top-quality US stocks and corporate bonds.

Analysis

The analysis challenges the notion of indiscriminate diversification, particularly for income-oriented investors in Closed-End Funds (CEFs), highlighting that over-diversification can lead to 'locked-in' subpar returns. It posits that a strategic combination of specialized, high-quality funds can be superior, citing the Nuveen S&P 500 Dynamic Overwrite Fund (SPXX) which yields 7.3% and has demonstrated an 8.2% ten-year annualized portfolio return, and the PIMCO Dynamic Income Fund (PDI), a corporate bond CEF yielding 14.1% with an 8.7% year-to-date return. Together, SPXX and PDI offer a 10.7% average yield, illustrating effective diversification with strong complementary performance. In contrast, the Clough Global Opportunities Fund (GLO), despite an attractive 11.3% yield and broad geographic diversification, serves as an example of diversification potentially gone awry. GLO's long-term annualized return of 3.2% over the past decade substantially trails its current yield and its global stock benchmark, the Vanguard FTSE All-World Ex-US ETF (VEU), despite GLO's strong recent year-to-date performance attributed to outperforming foreign markets. The core argument is that 'convenient' but underperforming diversification, as seen with GLO, should be avoided in favor of targeted exposures to high-performing asset classes.

Key Decisions for Investors

• Investors should prioritize long-term total return and benchmark-relative performance over superficial diversification and high current yields when selecting CEFs for income.
• A combination of specialized US equity CEFs, such as SPXX, and corporate bond CEFs, like PDI, may offer a more effective path to high income and robust returns than broadly diversified global funds with weaker historical performance.
• Re-evaluate holdings in globally diversified CEFs like GLO if their long-term returns significantly lag their yields and relevant benchmarks, as this could indicate a risk to principal or sustained underperformance despite attractive payouts.
