Explore how differences in portfolio size, sector focus, and risk profiles set these two small-cap growth ETFs apart for investors.
The State Street SPDR S&P 600 Small Cap Growth ETF (SLYG 1.78%) and the iShares Morningstar Small-Cap Growth ETF (ISCG 1.27%) differ in cost, portfolio breadth, and historical drawdowns, with ISCG offering lower fees and broader industrial exposure but showing higher volatility over time.
Both SLYG and ISCG target U.S. small-cap growth stocks, but each takes a distinct approach to sector weighting, holdings count, and recent performance. This comparison looks at cost, risk, returns, and portfolio construction to help investors decide which fund may better fit their preferences.

What this means for investors
Investing in small-cap exchange-traded funds (ETFs) is a good way to get exposure to a broad universe of small-cap stocks, and is generally considered a solid approach to diversifying your portfolio. Small-cap stocks — generally considered to be stocks with market caps between $250 million and $2 billion — tend to be more volatile than their large-cap peers, featuring more risk but also greater upside potential.
In this comparison, ISCG stands out for its broader total portfolio (though it has fewer total assets under management than SLYG) and its heavier bent toward industrials stocks. It also features a much lower expense ratio than SLYG, but misses slightly in the dividend matchup. Over the past five years, it’s returned slightly less and sports a much more extreme maximum drawdown of more than 40%.
Both small-cap ETFs aim to hold stocks that feature growth characteristics, which makes sense for investors who are looking at this sector of the market. Those who value dividend yield may be swayed more by SLYG, though some of those gains may be offset by the ETF’s slightly higher expense ratio.
