Both the Vanguard Growth ETF (VUG 1.77%) and the iShares Russell Top 200 Growth ETF (IWY 1.72%) aim to give investors exposure to large-cap U.S. growth stocks, but they do so by tracking different indexes and using distinct portfolio construction methods.
This analysis examines their cost structures, recent performance, risk profiles, and portfolio characteristics to help investors weigh which fund may appeal more for their needs.

What's inside
IWY tracks large-cap U.S. growth stocks with a portfolio of 110 holdings. Around 55% of assets are allocated to the technology sector, with 13% toward communication services and 11% to consumer cyclical. Its largest positions are Nvidia, Apple, and Microsoft. The fund has a 16-year track record and no notable structural quirks.
VUG, by contrast, holds 160 stocks and provides exposure that is similarly concentrated in technology (51%), with communication services and consumer cyclical making up 15% and 14%, respectively. Its top holdings match IWY's, but each stock makes up a slightly smaller portion of the portfolio compared to IWY.

What this means for investors
IWY and VUG are similar in many ways on the surface, but they offer subtle differences that could make a difference for investors.
IWY is narrower, with fewer holdings and a greater emphasis on the tech industry. While the two funds share the same top three stocks, these holdings make up around 38% of the portfolio for IWY compared to 32% for VUG. This is a subtle difference, but it could have an impact if Nvidia, Microsoft, and Apple see significant price swings either positively or negatively.
The two funds have seen similar performance in recent years, and with comparable max drawdowns, they've also experienced roughly the same levels of volatility.
The other main difference between them, then, is their fee structure. VUG boasts a lower expense ratio of 0.04%, charging $4 per year in fees for every $10,000 invested. IWY's expense ratio is 0.20%, resulting in fees of $20 per year for every $10,000. While it may seem subtle, IWY's five-times higher fee can add up if you have hundreds of thousands of dollars invested.
