Vanguard Morningstar ETF vs. Invesco SmallCap ETF: A Cost and Strategy Comparison
When evaluating the performance and cost of two prominent exchange-traded funds, the Vanguard Morningstar Mega Cap Growth ETF (MGK) and the Invesco S&P SmallCap 600 Revenue ETF (RZG), the expense ratios stand out as a key differentiator. MGK comes with a much lower 0.05% annual fee. This is compared to RZG’s 0.35% rate. For investors, this 30-basis-point gap in cost can add up over time. This is especially true when compounded over years of investing. Sara Appino, a financial analyst, highlighted that MGK's low-cost structure is a compelling reason to consider it. This is for those focused on large-cap growth opportunities.
The Vanguard fund is heavily tilted toward technology, with nearly 60% of its assets in the sector. This includes major names such as Apple, Microsoft, and especially Nvidia, which alone accounts for over 13% of the fund. The Communication Services sector takes the second-highest allocation with 16%, followed by Consumer Cyclical at 11%. This makes MGK one of the most concentrated ETFs in the technology space, focusing on the largest and fastest-growing companies in the U.S. market.
RZG's Diversified Approach
In contrast, RZG takes a broader approach. Its holdings are spread across the S&P SmallCap 600 index. It places particular emphasis on Healthcare and Industrials. These represent 23% and 17% of the portfolio, respectively. While it holds a larger number of stocks—127 in total—RZG focuses on small-cap companies. These are growing based on revenue, rather than market capitalization. This strategy includes holdings like ACM Research and Dave Inc. These, while not as well-known as Apple or Microsoft, offer exposure to emerging sectors. These sectors have potential for rapid expansion.
Over the past year, RZG has generated stronger total returns compared to MGK. However, it also experienced a more pronounced maximum drawdown. This was over the last five years, indicating higher volatility. While some investors might be willing to tolerate the risk for potential gains, the higher expense ratio of RZG means something. A larger portion of those returns is eaten away by fees. For most investors, especially those with a long-term focus, MGK’s cost advantage and more stable returns make it the more attractive option. This is as detailed in a recent Nasdaq analysis.
Despite their differences in strategy and performance, both MGK and RZG have minimal dividend yields. Each is below 1%. This suggests that neither fund is particularly well-suited for investors seeking regular income. However, in the case of MGK, the low expense ratio could make it a more appealing choice over time. The compounding benefits of a lower-cost fund may outweigh the modest dividend payouts.
Choosing Between MGK and RZG
The fundamental difference between these two ETFs lies in their target market segments. MGK focuses on the largest, most established growth companies in the U.S., which are often at the forefront of technological innovation and have a proven track record of compounding value. RZG, on the other hand, is designed to capture the potential of smaller companies with strong revenue performance, making it a more speculative and potentially volatile option. The recent decade has been a period of dominance for large-cap stocks, especially in the technology sector, due to factors like artificial intelligence and cloud computing. As a result, many investors have found greater returns in ETFs like MGK.
Still, the decision between these funds may come down to an investor's risk tolerance and time horizon. RZG might be the better option for those who believe that the small-cap market is due for a rebound or who are interested in revenue-based investing. However, for the average investor looking for a lower-cost, more predictable option that aligns with the broader trends in today’s market, MGK remains the more favorable choice.
