Our read on each fund

ETF.net Research

MGCAVanguard Morningstar Mega Cap ETF

TOPTCiShares Top 20 U.S. Stocks 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.

TOPT Most mega-cap funds hold hundreds of names. TOPT holds twenty: an index of the largest U.S. companies, and nothing behind them. It is the most concentrated way iShares sells the giants.

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.

TOPT The fund seeks to track an index composed of the 20 largest U.S. companies by market capitalization.

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.
  • TOPT Twenty holdings, one ticker. It tracks an index of the 20 largest U.S. companies by market value, so you get the giants without picking among them.
  • The 0.20% fee sits right at the median for mega-cap funds, and matches iShares' 100-stock OEF for a far more concentrated slice of the same universe.
  • Membership is set by S&P index rules, not a manager's judgment, and the fund distributes 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.
  • TOPT With 20 names, the top few positions steer results in both directions, and the sector mix is simply whatever happens to be biggest.
  • Broader mega-cap exposure costs less elsewhere: MGC and MGK charge 0.05%.
  • Launched in October 2024, so there is only a short record to judge it by.
