MGCAVanguard Morningstar Mega Cap ETF

OEFBiShares S&P 100 ETF

In short

MGC Mega cap without the guesswork. MGC owns roughly 190 of the largest US companies for 0.05% a year, a fraction of what most rivals in its aisle charge, and has run that way since 2007.

OEF The S&P 500's inner circle. OEF has held about 100 U.S. mega-caps since 2000, a plain index fund that owns the giants and skips everything below them.

Stated mandate

MGC The fund seeks to track the CRSP US Mega Cap Index and provide diversified exposure to the largest U.S. stocks through passive full replication.

OEF The fund seeks to track an index composed of 100 U.S. mega-cap stocks.

Why people hold it

MGC 0.05% a year, against 0.20% at the two iShares mega-cap options (OEF, TOPT) and 0.47% at SIXA. Same neighborhood of stocks, much smaller toll.
Roughly 190 names versus 100 in OEF and 20 in TOPT: the widest net in the mega-cap group, without wandering into mid or small caps.
No engineering to decode. It buys the CRSP US Mega Cap Index outright, full replication, and has tracked that index about as tightly as an index fund can.
Trading since 2007 and now a multi-billion-dollar fund, it sits among the strongest implementations in its mega-cap peer group.

OEF Launched in 2000, one of the longest-running mega-cap index funds around, and now a multi-billion-dollar fund.
Tracks the S&P 100 Index with very little slippage, which is the whole job of a fund like this.
No leverage, no derivatives overlay: a standard 1940 Act stock fund holding about 100 U.S. mega-caps, paying out quarterly.

Worth knowing

MGC Giants only, by design. No mid or small caps, so the mix leans wherever the biggest US companies happen to cluster.
Moderately traded rather than one of the tape's busiest tickers, so spreads can run a touch wider than the largest broad-market funds.
Distributions land quarterly, not monthly.

OEF At 0.20% a year, it costs four times the 0.05% Vanguard charges on mega-cap rivals MGC and MGK.
About 100 names, weighted by size, means the handful of largest U.S. companies set the tone. Concentration is the design, not a bug.
Moderately traded rather than the busiest ticker in mega-cap land, so limit orders earn their keep in fast markets.
