About iShares Russell 2000 Growth ETF
IWO is BlackRock's iShares fund that tracks the Russell 2000 Growth Index, which holds the faster-growing half of the small US companies in the Russell 2000. It has been around since 2000, manages roughly $14–15 billion and owns about 1,100 stocks, so no single holding is more than about 1% of the fund.
How the fund works
IWO is a passive fund that tries to match the Russell 2000 Growth Index, with no leverage. The index picks Russell 2000 companies with stronger expected growth and sales growth and higher price-to-book ratios, and it is rebuilt once a year. The fund charges about 0.24% a year, which is more than some rival small-cap growth funds. Dividends are small (a yield of about 0.5%) and are paid quarterly. Recently it held roughly 30% healthcare, about 22% technology and about 15% industrials, so it leans heavily on biotech and tech. It also tends to swing more than the broader market (beta of roughly 1.2–1.5).
