Investors looking for large-cap U.S. growth exposure often come across two funds that function essentially as twins: the iShares Russell 1000 Growth ETF and the Vanguard Russell 1000 Growth ETF. This comparison stands out because the products do not simply compete; they replicate the same underlying index with matching holdings, sector allocations, and risk characteristics. When two funds deliver nearly identical exposure, the focus naturally shifts from what they own to how efficiently they deliver it. Factors like cost, liquidity, replication method, and issuer structure become the key points of differentiation.
The iShares Russell 1000 Growth ETF (IWF), from BlackRock, is a passive fund designed to track the Russell 1000 Growth Index. It holds about 390 positions using representative sampling. The portfolio is concentrated at the top, with NVDA at roughly 15% of assets, AAPL near 8%, MSFT near 6%, and Alphabet (GOOGL and GOOG) combined around 11%, plus AVGO, META, TSLA, MU, and LLY. Technology makes up about 55% to 60% of the fund, with consumer discretionary in the low-to-mid teens and communication services near 12%. The expense ratio sits at approximately 0.19%, and the fund offers strong liquidity along with a history dating back to 2000. I also checked this using Tickeron’s AI Screener to see how the holdings line up against peers.
The Vanguard Russell 1000 Growth ETF (VONG) follows the same Russell 1000 Growth Index but employs full replication, holding every constituent at its market-cap weight. It maintains a similar count of around 390 positions and the same top holdings: NVDA, AAPL, MSFT, Alphabet, AVGO, META, TSLA, MU, and LLY. Sector weights align closely with the index, technology again at 55% to 60%. What sets it apart is the expense ratio of about 0.07%, one of the lowest in its category. Launched in 2010, it has a smaller AUM than IWF yet remains quite liquid.
Both ETFs sit at the heart of the dominant market theme around artificial intelligence and semiconductors. Heavy weighting in NVDA, AVGO, and MSFT means performance tracks closely with AI capital spending, cloud demand, and data-center expansion. That same concentration introduces risk if earnings or expectations shift for these names. Interest-rate sensitivity, growth-versus-value rotations, regulatory pressures on big tech, and semiconductor supply-chain issues all remain relevant factors. From what I see, these macro drivers continue to shape outcomes across market cycles.
Because both track the identical index, recent performance has been virtually the same, with any minor differences stemming mainly from fees and slight tracking variations. Over longer horizons, the expense gap gives VONG a modest edge through compounding. Volatility and drawdown profiles match closely. The main operational distinction lies in scale: IWF provides greater AUM, tighter spreads for larger trades, and a more developed options market, whereas VONG delivers comparable beta at lower cost. For most long-term holders the fee advantage stands out; shorter-term traders may value the liquidity of IWF more.
In my research process, I frequently turn to Tickeron’s AI Screener to compare ETFs like these side by side.
