Why is iShares Russell Top 200 Growth ETF (IWY) stock moving?
No news items or SEC filings were found for IWY in the window, so this view rests only on the 30-day market data. The ETF peaked at 290.23 on Oct 28 and then fell about 10.6% to a 259.55 low on Nov 5, the heaviest session in the set at 868,047 shares and 14,574 trades, with the close at 259.83. It has since recovered to 268.98 on Nov 10, about 3.6% above that low but still roughly 7.3% below the Oct 28 high. The Nov 9 and Nov 10 closes were near 271 and 269, and volume eased from 868,047 on Nov 5 to 377,172 and 386,058, so the rebound is holding without a fresh volume spike. The last close sits below the 14-session average close of about 277, which tilts the short-term picture slightly negative. Without any company, sector or macro news to explain the Nov 5 drop, the cause of the sell-off is unknown, and that gap is the main reason confidence stays low.
About iShares Russell Top 200 Growth ETF
IWY is a BlackRock iShares ETF, launched in 2009, that tracks the Russell Top 200 Growth Index: the growth-style stocks among the 200 largest US companies. It is more concentrated than broad growth funds, holding only about 105 stocks, with roughly 60% of assets in its top 10 holdings, led by Nvidia, Apple, Microsoft, Alphabet and Broadcom.
How the fund works
The fund passively tracks the Russell Top 200 Growth Index. The index picks large US stocks with growth traits, such as higher price-to-book ratios and forecast earnings and sales growth, and weights them by market value. BlackRock uses representative sampling, meaning it may not hold every index stock in exact proportion. The index is reconstituted regularly (historically once a year). The expense ratio is about 0.20%, assets are roughly $15 billion and the dividend yield is small, about 0.3–0.4%, paid quarterly. The fund is classed as non-diversified. Technology makes up well over half of the portfolio, so a few mega-cap stocks drive most of its returns.
