IWF: Concentration And Low Responsiveness Vs. Growth

  • iShares Russell 1000 Growth ETF offers aggressive growth exposure with high tech concentration, resulting in significant concentration risk despite a large number of holdings. Performance outpaces most active funds and matches passive peers, with superior upside in rallies and similar drawdowns to alternatives like SPYG and VUG. Concentration risk, especially in tech mega caps, is a real concern and could hurt in a sector-specific downturn, but hasn't materialized historically.
