Vanguard S&P 500 Growth vs. Invesco SmallCap Revenue: How Do These ETFs Stack Up?

Investors choosing between Invesco S&P SmallCap 600 Revenue ETF (RZG 0.91%) and Vanguard S&P 500 Growth ETF (VOOG 1.00%) must weigh the higher historical returns of large-cap growth against the recent momentum of small-cap revenue-weighted stocks.

Both funds target growth, but they look for it in very different corners of the market. While RZG uses a revenue-weighted strategy to filter the small-cap universe, VOOG tracks the growth-oriented subset of the S&P 500, offering a traditional large-cap growth profile.

Snapshot (cost & size)

| Metric | RZG | VOOG | | --- | --- | --- | | Issuer | Invesco | Vanguard | | Share price (as of June 30, 2026) | $72.69 | $82.62 | | Expense ratio | 0.35% | 0.07% | | 1-yr return (as of June 30, 2026) | 44.5% | 25.7% | | Dividend yield | 0.40% | 0.50% | | Beta | 1.12 | 1.17 | | AUM | $142.9 million | $26.5 billion |

Beta measures price volatility relative to the S&P 500; beta is calculated from five-year monthly returns. The 1-yr return represents total return over the trailing 12 months. Dividend yield is the trailing-12-month distribution yield.

The Vanguard fund is more affordable, with an expense ratio of 0.07% compared to 0.35% for the Invesco ETF. VOOG also offers a slightly higher trailing-12-month dividend  yield.

Performance & risk comparison

| Metric | RZG | VOOG | | --- | --- | --- | | Max drawdown (5 yr) | (38.3%) | (32.7%) | | Growth of $1,000 over 5 years (total return) | $1,401 | $1,954 |

What this means for investors

I think VOOG looks more attractive here. The Vanguard fund has a lower expense ratio, higher dividend yield, and more stocks than the Invesco ETF. I will concede VOOG's portfolio, despite the greater number of equities, is pretty concentrated. Nvidia, Apple, and Microsoft make up nearly one-third of the fund. In contrast, no position in RZG exceeds 4%. But VOOG has a better long-term return than RZG.

Finally, the Vanguard fund absolutely dwarfs RZG in terms of assets under management. As a result, VOOG has far greater average trading volume -- by orders of magnitude. This increased liquidity may be attractive to some investors.
