The ETF’s portfolio is heavily weighted toward the Information Technology and Healthcare sectors, reflecting the dominance of high-market-cap firms in the current U.1S. economy. Because the Russell 1000 is market-cap weighted, the funds performance is significantly influenced by the largest multi-national corporations rather than small-cap volatility.
