MGC: Eliminate The Fluff Of The S&P 500

The Vanguard Mega Cap Index Fund ETF offers a focused, cost-efficient way to capture mega-cap leadership, particularly in technology, while trimming slower-growth S&P 500 constituents. MGC has outperformed traditional index ETFs like SPY and IVV over the long term, delivering a 580.1% total return since inception, but with higher volatility and less diversification. The ETF is heavily allocated to technology (37.62%), positioning it to benefit from AI-driven growth, yet exposing it to sector-specific risks and potential downside during market selloffs.
