ETF inflows and outflows can tell you a lot about investor sentiment. While these trends are technically a lagging indicator, they’re still a useful tool for understanding where money is flowing in the market.
Inflows represent the amount of new money being added to an ETF, while outflows show the money being withdrawn. These are typically measured on a net basis, which means total creations minus total redemptions. Why are these metrics important?
First, they can reveal shifts in asset allocation preferences. For example, inflows into bond ETFs might indicate investors are seeking safety, while outflows from a tech ETFs could signal profit-taking or reduced risk appetite.
Second, inflows and outflows can sometimes signal momentum—or lack thereof. A sudden surge in inflows to a niche ETF might hint at growing interest in its underlying theme, while persistent outflows could reflect fundamental concerns about its holdings.
As January 2025 ends, we’re taking a closer look at the ETFs with the largest one-month trailing inflows and outflows to see where investors were putting their money—and where they weren’t.

Investor appetite for low-cost beta remains strong, particularly in U.S. large-cap equities. The largest inflows in January went to the Vanguard S&P 500 ETF
This ETF took in a blistering $24.17 billion of net inflows. If this pace continues, VOO could potentially overtake the SPDR S&P 500 ETF Trust
Close behind VOO was its main competitor, the Invesco QQQ ETF
Despite not being explicitly labeled as a tech-focused ETF, QQQ has effectively turned into a large-cap growth fund due to the Nasdaq’s history of listing tech-heavy companies. Currently, the Nasdaq-100 index, which QQQ tracks, has over 50% of its holdings concentrated in the technology sector.
This inherent tilt toward growth stocks makes QQQ a go-to choice for investors seeking exposure to major tech players like Apple, Microsoft, and Nvidia.
Following QQQ in January’s inflows was its sibling fund, the Invesco NASDAQ 100 ETF
The trade-off? QQQ is more liquid with an options chain, making it better suited for institutional investors and active traders, while QQQM appeals to buy-and-hold retail investors seeking cost efficiency.
Similarly, for VOO, a close competitor racked up inflows as well. The SPDR Portfolio S&P 500 ETF
Like QQQM, SPLG appeals to cost-conscious investors while still offering the same exposure to the S&P 500 at a slightly lower cost than VOO.
In a surprising turn, the SPY led January’s outflows with $4.74 billion in net redemptions. This might pave the way for VOO to dethrone SPY as the reigning king of ETFs.
Despite being the first U.S.-listed ETF and maintaining its legacy status, SPY’s 0.0945% expense ratio is becoming harder to justify, especially when compared to VOO’s 0.03%.
Additionally, more sophisticated investors are beginning to dislike SPY’s unit investment trust (UIT) structure. Unlike a traditional ETF, SPY’s UIT structure doesn’t allow dividend reinvestment between distributions, which creates a slight cash drag over time.
However, SPY does have one major advantage: its daily-expiry options, a feature that VOO currently lacks. In my opinion, if SPY wants to maintain its dominance, lowering its expense ratio is a must.
The second-largest outflows came from the iShares Russell 1000 Value ETF
With growth outperforming value during much of 2024 and early 2025, it’s no surprise that IWD has faced challenges retaining assets.
The third-largest outflows were sector-specific, with the Energy Select Sector SPDR Fund
These developments have created significant headwinds for energy markets, leaving investors wary of the sector’s near-term outlook.
