Our read on each fund

OEFBiShares S&P 100 ETF

TOPTCiShares Top 20 U.S. Stocks ETF

In short

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.

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

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

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

Why people hold it

  • 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.
  • 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

  • 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.
  • 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.
