Vanguard Mega Cap ETF, an exchange-traded share class of Vanguard Mega Cap Index Fund (the Fund), seeks to track the performance of a benchmark index that measures the investment return of large-capitalization stocks in the United States.
The fund tracks the CRSP US Mega Cap Index, which measures the top 70% of investable U.S. equity market capitalization, by holding all or substantially all of the index's stocks in the same weights. Because the fund replicates the index rather than sampling it, its returns will closely track the index's performance. The fund may become concentrated in particular issuers or industries if the index itself becomes concentrated due to market movements or index rebalancing.

How it has done
MGC share class · total returns with dividends reinvested
Volatility over the last 12 months: 14.18%. Past returns are a record, not a forecast.
The 2 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.05% | +31.57% | +95.47% | +100.58% | -7.84% | |
| 0.05% | +31.55% | +95.43% | +100.46% | -7.84% |
These classes hold the same portfolio, so the 0.12pp spread over 5 years is the cost difference between them — roughly 0.02pp a year — not a difference in what they own.
