Our read on each fund

IWOBiShares Russell 2000 Growth ETF

VUGAVanguard Morningstar Growth ETF

In short

IWO No data

VUG Three basis points buys roughly 170 US large-cap growth names. Running since 2004, over $100 billion in assets, and it tracks its index about as closely as an index fund can.

Stated mandate

IWO No data

VUG The fund seeks to track a benchmark index measuring the investment return of large-capitalization growth stocks.

Why people hold it

IWO No data

  • VUG 0.03% a year against a 0.18% median for its growth peer group. A rival tracking the same declared index charges 0.36%, twelve times more for the same shopping list.vanguard.com
  • One of the largest and most heavily traded funds in US large-cap growth, and among the tightest index implementations in that group. Deep volume tends to mean thin spreads.
  • Trading since January 2004, so the record spans full market cycles rather than a backtest. Distributions land quarterly.

Worth knowing

IWO No data

  • VUG Cap-weighted, so the biggest mega-caps dominate the top of the book. That makes it one of the more concentrated portfolios in this cohort.vanguard.com
  • A style sleeve, not the whole market: growth screens only, large caps only. When growth is out of favor it can swing harder than a total-market fund.
  • SPYG and SCHG sit at 0.04%, so the price edge is a rounding error. The real gap is how each index defines a growth stock.
