Passive But Not Static: Navigating the VettaFi Index Rebalance

• While index-based ETFs are often viewed as buy-and-hold vehicles, quarterly rebalancing ensures these portfolios undergo a strategic facelift to remain aligned with evolving market leadership and current economic realities.
• Quarterly rebalancing for thematic indexes captured a shift in the international exposure. GAMR added companies such as Bilibili and NetEase.
• For fundamentally constructed ETFs, rules-based rebalancing maintains quality control by rotating into superior cash flow and dividend profiles.

A week ago, while many were recovering from the Exchange conference, a significant wave of index-based ETFs underwent their quarterly rebalancing and reconstitution. While the growth of actively managed ETFs has dominated the headlines recently, the lion’s share of industry assets remains in index-based products. Despite being passive, they are far from static. Many of them, including those tracking VettaFi indexes, receive a strategic portfolio facelift every three months to ensure they remain aligned with their underlying objectives.

“Over the past year, the investment landscape has been fundamentally reshaped by a second wave of AI integration, a global push for energy security, and the emergence of a more fragmented trade environment,” explained Dalton Easterwood, head of index products at TMX VettaFi. “These periodic realignments allow investors to capture emerging leaders while shedding laggards, ensuring the portfolio evolves at the same pace as the modern economy.”

Since the last index update in December, the broader U.S. equity market has faced fresh headwinds. Concerns regarding Middle East instability, delayed interest rate cuts, and shifting growth expectations for artificial intelligence have altered the risk-return profile for many companies.

Let’s look at how VettaFi’s March 2026 index rebalancing impacted several ETFs across the thematic and fundamental landscapes. Below are just examples of some of the position changes. 

In the thematic arena, rebalancing ensures that exposure remains pure as company fundamentals shift. The Amplify Video Game Leaders ETF (GAMR C) saw a rotation within its international holdings, adding Bilibili and NetEase while dropping Nexon. This maintains the fund’s focus on the developers and platforms truly driving global engagement. Meanwhile, in the US, NVIDIA was reduced by 1.89% to a capped weight of 10.0%, while Meta Platforms was cut by 1.60% to the same level. GMR only owns 21 stocks so any change is notable.

Though the Procure Space ETF (UFO ) did not add new names this go-around the ETF tilted its weightings. The reweighting boosted established players like EchoStar, Garmin, and Trimble. Additionally, it reduced Planet Labs and MDA Space. This reflects the index’s rules-based adjustment to market caps and liquidity.

Fundamentally weighted strategies also find rebalancing critical. The VictoryShares Small Cap Free Cash Flow ETF (SFLO ) added several names including Build-A-Bear Workshop, Grid Dynamics, and Healthcare Services Group after they cleared the index’s rigorous free cash flow yield screens. Conversely, BK Technologies, Genie Energy, and Smith Douglas Homes were removed as their cash flow growth profiles no longer met the index’s top-tier requirements.

Finally, the Franklin US Dividend Booster Index ETF (XUDV ), which tracks the VettaFi New Frontier US Dividend Select Index, underwent a refresh to its yield-seeking core. The fund added Lumentum Holdings Micron Technology and Western Digital while boosting exposure to Ares Management and Best Buy. To maintain its yield-to-volatility discipline, the index exited Dow Inc, Palantir Technologies and Pulte Group  and reduced positions in Chevron and Edison International.

These moves serve as a reminder to look under the hood Index investing isn’t about setting it and forgetting it. A disciplined, rules-based process evolves alongside the market and helps keep your and your client portfolios on track.
