Focused on the growth sector, both the iShares S&P Small-Cap 600 Growth ETF (IJT +0.72%) and the Invesco S&P SmallCap 600 Pure Growth ETF (RZG +0.63%)offer broad-based exposure to small-cap growth companies. However, RZG focuses on a “pure” growth subset based on sales, earnings, and momentum. This comparison highlights where their approaches diverge in terms of cost, performance, risk, and portfolio composition.

What's inside
IJT holds 342 stocks, offering broad exposure across small-cap growth, with the largest sector weights in technology (20%), industrials (19%), and healthcare (17%). Its top holdings—Arrowhead Pharmaceuticals (ARWR 0.68%)(undefined), Armstrong World Industries (AWI +2.44%), and InterDigital (IDCC +0.78%) are each under 1.4% of assets, helping to spread risk. The fund’s 25-year track record makes it one of the longest-running small-cap growth ETFs on the market.
RZG, in contrast, tracks a “pure” growth methodology and holds 135 stocks, with a heavier tilt towards healthcare (27%). Top positions include Progyny (PGNY 1.60%), ACM Research (ACMR +8.19%), and ARMOUR Residential REIT (ARR +0.17%).

What this means for investors
It's important to understand what "pure" growth actually is. RZG is based on the S&P SmallCap 600 Pure Growth Index, which utilizes a growth score to identify stocks that exhibit strong or "pure" growth. The three factors used to create that score are sales growth, the ratio of earnings change to price, and momentum. Companies that don't meet the criteria are excluded from the fund, which is why RZG has nearly three times fewer total holdings of IJT.
Pure growth ETFs are designed to outperform regular growth ETFs, but that doesn't guarantee it will always be the case. RZG has outperformed IJT over the last 12 months; however, when examining the period of the last five years, the 13.43% return of the pure growth ETF falls short of IJT's 21% return within that period.
For short-term gains, RZG may be the more ideal option for investors. If investors want to prioritize cheaper expenses, long-term gains, as well as broader exposure and higher dividend yield, ITJ is more ideal.
