Our read on IYM

ETF.net Research

BTrading since 2000, IYM is the old hand of US materials: roughly 40 companies that make the stuff everything else is built from. The trade-off is price, at 0.38% while the cheapest trackers in the group sit near 0.08%.

Stated mandate

The fund seeks to track an index composed of U.S. equities in the basic materials sector.

Why people hold it

  1. 01Running since 2000 through multiple commodity cycles, now a multibillion-dollar fund with the iShares operation behind it.
  2. 02About 40 US names: a concentrated, purely domestic read on chemicals, metals and packaging, with no overseas miners in the mix.
  3. 03Moderately traded and long established, which lands it in the upper half of the broad materials peer group.

Worth knowing

  1. 01The 0.38% fee matches the cohort median but runs several times XLB (0.08%), VAW (0.09%) and FMAT (0.08%), which cover similar US materials ground.
  2. 02Concentration cuts both ways: with about 40 holdings, a couple of chemical or mining giants can steer the whole fund.
  3. 03One sector's slice of the market, not a broad-market fund, and distributions arrive quarterly rather than monthly.
