Performance & Risk Comparison

What's Inside

IWY tracks large-cap U.S. growth names with a pronounced technology focus—66% of assets—alongside 11% in consumer cyclicals and 7% in healthcare. With just 110 holdings, the fund is more concentrated than most broad growth peers. Top positions include Nvidia Corp (NVDA 0.44%) at 13.88%, Apple Inc (AAPL 0.93%) at 12.12%, and Microsoft Corp (MSFT +0.77%) at 11.41%. IWY has a fund age of 16.3 years, offering a long track record for investors to evaluate.

VONG, in contrast, provides broader diversification with 394 holdings and a slightly more balanced sector allocation: 53% technology, 13% consumer cyclicals, and 13% communication services. Its top holdings—NVIDIA Corp, Apple Inc, and Microsoft Corp—are similar, but each represents a smaller share of assets, limiting single-stock concentration risk. Neither fund introduces leverage, currency hedging, or other structural quirks.

What This Means For Investors

There's no shortage of great ETFs out there for growth-oriented investors. And, in their own ways, both Vanguard Russell 1000 Growth ETF (VONG) and iShares Russell Top 200 Growth ETF (IWY) could fit the bill for any given growth investor. Here are the key details that could help someone decide between the two.

First off, VONG takes a more diversified approach, with nearly 400 holdings spread over many industries. Big tech names like Nvidia, Apple, and Microsoft remain the bedrock of its holdings, but the fund also holds plenty of other names from sectors like retail, healthcare, and financials. Perhaps VONG's biggest appeal is its expense ratio of 0.07% -- meaning that investors only pay $7 in fees for every $10,000 invested in the fund.

Turning to IWY, investors find a fund that zeroes in on the top growth companies. Rather than 400 holdings, IWY has closer to 100 holdings. As a result, big tech dominates. Nvidia, Apple, and Microsoft alone comprise 37% of its overall portfolio. Over the last five years, this concentration in big tech has paid off. IWY has generated a total return of 118%, equating to a compound annual growth rate (CAGR) of 16.9%. That surpasses VONG which has generated a total return of 106%, with a CAGR of 15.5%.

In summary, IWY has generated superior returns, albeit with a higher expense ratio of 0.20%. Meanwhile, VONG has also delivered solid returns (beating the S&P 500) over the last five years. Its broader holdings list gives it superior diversification, and its lower expense ratio means investors pay less in fees. In short, both ETFs remain solid choices for growth-oriented investors, which means investors can tailor their choice to fit their investment philosophy. More aggressive investors may select IWY, while slightly more conservative and cost-conscious growth investors may favor VONG.
