Vanguard VOOG edges out MGK for long-term growth investors
While the Vanguard Mega Cap Growth ETF offers a lower fee, its S&P 500 counterpart delivers stronger recent returns and broader exposure, making it the preferred vehicle for sustained capital appreciation.
A recent analysis by Brendan Coffey for The Motley Fool compares the Vanguard Mega Cap Growth ETF (MGK) and the Vanguard S&P 500 Growth ETF (VOOG), concluding that the latter is the superior choice for long-term investors. The report highlights that while MGK targets the largest market-capitalisation names with a lower expense ratio, VOOG casts a wider net across the S&P 500, offering a more balanced approach to growth equity exposure.
MGK holds 56 stocks with an expense ratio of 0.05%, whereas VOOG holds 148 stocks at a slightly higher cost of 0.07%. The structural difference is significant: two-thirds of MGK’s assets are concentrated in its top 10 holdings, nine of which are technology stocks, with Eli Lilly & Co rounding out the top tier. In contrast, VOOG’s top 10 holdings account for 56% of its assets, also dominated by technology, with Micron Technologies as the sole non-tech entry in that group.
Performance metrics favour the broader fund in recent periods. VOOG delivered stronger one-year returns than MGK, despite exhibiting higher volatility. Over a three-year period, VOOG returned 25.8% compared to MGK’s 23.7%. In the five-year look-back, VOOG posted 14% returns against MGK’s 14.3%. However, over the 10-year horizon, MGK achieved annualised gains of 19%, outpacing VOOG’s 18%.
Income generation also differs between the two vehicles. VOOG offers a trailing-12-month dividend yield of 0.50%, based on a payout of $0.37 per share on a recent price of approximately $81.91. MGK provides a lower yield of 0.30%, with a trailing-12-month distribution of $0.29 per share on a price of roughly $88.18.
The analysis suggests that diversification remains a key driver for sustained performance in concentrated growth sectors. While both funds are heavily weighted towards large-cap technology, the broader exposure of VOOG has allowed it to outperform MGK in most time frames, supporting the conclusion that it is the more robust option for investors seeking long-term growth.
