Why is Vanguard Morningstar Mega Cap Growth ETF (MGK) stock moving?
MGK fell from 90.92 on Oct 28 to a close of 82.71 on Nov 5, a drop of about 9%, on the heaviest volume in the window (3.44M shares, 38,474 trades). The news found for the period is only two Benzinga performance articles, which are historical and do not explain the selloff, so the cause is not identified in the available data. Since the Nov 5 low (intraday 82.58), the ETF has recovered to 85.30 on Nov 10 on volume that has eased to about 1.4-1.6M shares a day, but it remains about 6% below the Oct 28 level. The cited 10-year annualized return of 17.24% describes past performance and says little about near-term direction. Key reference levels in the data are the 82.58 Nov 5 low and the 90.5-91 zone of late October.

About Vanguard Morningstar Mega Cap Growth ETF
Vanguard Morningstar Mega Cap Growth ETF is a passively managed fund that holds the largest growth-oriented US companies. It tracks the Morningstar US Mega Cap Growth Index (it previously tracked a CRSP index) and is very concentrated, with roughly 55 holdings, about 60% of the fund in technology, and its top 10 stocks making up close to two-thirds of assets.
How the fund works
The fund aims to match the Morningstar US Mega Cap Growth Index by owning every stock in the index (full replication). The index picks the biggest US companies that score well on growth measures such as earnings and sales growth, then weights them roughly by size. Top holdings include NVIDIA, Apple, Microsoft, Alphabet, Meta, Broadcom and Amazon, with NVIDIA and Apple each at roughly 12–14%. The expense ratio is approximately 0.05% a year, and the dividend yield is low, around 0.35%. Because so few stocks dominate the fund, it carries concentration risk, and it has tended to swing more than the broad market (beta roughly 1.3). Share counts and prices before about April 2026 may not line up with today's because of a share split around that time.
