Our read on OEF

ETF.net Research

BThe 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

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

Why people hold it

  1. 01Launched in 2000, one of the longest-running mega-cap index funds around, and now a multi-billion-dollar fund.
  2. 02Tracks the S&P 100 Index with very little slippage, which is the whole job of a fund like this.
  3. 03No leverage, no derivatives overlay: a standard 1940 Act stock fund holding about 100 U.S. mega-caps, paying out quarterly.

Worth knowing

  1. 01At 0.20% a year, it costs four times the 0.05% Vanguard charges on mega-cap rivals MGC and MGK.
  2. 02About 100 names, weighted by size, means the handful of largest U.S. companies set the tone. Concentration is the design, not a bug.
  3. 03Moderately traded rather than the busiest ticker in mega-cap land, so limit orders earn their keep in fast markets.
