iShares Russell Top 200 Growth 

IWY is a solid mega-cap ETF, holding a portfolio of growth stocks chosen from the 200 largest US companies in the Russell Top 200 Index. Stocks are selected and weighted based on two main growth factors: medium-term growth forecasts and historical sales per share growth. The index follows Russell's style methodology, which causes IWY to tilt heavier in technology, while comparatively reducing its financials exposure. These sector tilts make IWY somewhat less volatile and thus, appealing to investors looking for a more stable mega-cap growth fund. Notably, instead of replicating the index, the fund uses a representative sampling indexing strategy. The index is reconstituted and rebalanced on an annual basis.
