Changing the clock does not alter the amount of sunlight. It simply shifts when we enjoy it. In the financial realm, adjusting the investment calendar operates in a very similar fashion.
“Moving from October to November does not erase the trends that defined October. Likewise, transitioning from 2026 to 2027 will not suddenly make artificial intelligence, inflation, fiscal deficits, geopolitical fragmentation, or higher interest rates disappear. What can change is how and where investors experience them.” Thus, in the case of AI, “the opportunity could broaden from the companies building the infrastructure to those utilizing it to enhance productivity. Consequently, biotechnology emerges as an area of interest.”
In fixed income, elevated yields provide significant income, yet persistent interest-rate pressures advise caution regarding duration risk and favor focusing on short-duration exposures. At the portfolio level, a world where inflation and macroeconomic shocks can simultaneously pressure stocks and bonds “reinforces the need for broader diversification tools that help provide greater resilience against inflation.” Ultimately, “it is not so much about predicting the next market regime as it is about building a portfolio capable of adapting to it.”
This repositioning can be uncomfortable, as it requires expanding sources of return, managing risk deliberately, and diversifying based on growth and inflation outcomes.
General flow overview
After logging its worst monthly performance in over 4 years, core aggregate bonds delivered their best monthly performance in over 3 years, climbing by more than 2.4% in October. Just as this reversal occurred, fixed-income ETFs recorded their largest capital inflows in history for a single month, with a record haul of $74B. This also marked the 6th consecutive month with inflows exceeding $50B, setting an all-time record (prior to this year, a single month exceeding $50B had never been recorded).
The robust October intake, combined with this streak of $50B+ months, propelled year-to-date fixed-income ETF inflows beyond $542B, on track to reach $660B by year-end. These inflows have been driven by a more balanced mix of both low-cost and active fixed-income ETFs. This marks a shift from prior years, when low-cost vehicles commanded a higher share of inflows, reflecting the growing adoption of active fixed-income ETF strategies within portfolios.
These record bond flows also showed depth: 76% of fixed-income ETFs logged inflows in October, outpacing the historical 73% average and aligning with the 2026 average of 78%.
The scale, depth, and breadth of bond flows explain why fixed-income ETFs stand as one of the long-term growth engines of the exchange-traded fund industry.
Indeed, this record intake of $74B into fixed-income ETFs propelled broader ETF industry subscriptions to $211B in October, marking the 2nd-highest figure in its history. Consequently, year-to-date net investment inflows across the U.S.-listed ETF industry stand at $1.75T. Ultimately, the milestone of $2T in inflows by the close of 2026 is increasingly within reach.
Asset classes: major flows in key segments
The 2 primary asset classes led industry flows, while the other 5 smaller asset classes registered net outflows. Both equity and fixed-income ETFs crossed major milestones in year-to-date cumulative flows in October: inflows into equity ETFs surpassed $1T, while fixed-income ETFs exceeded $500B.
Among smaller asset classes, commodities remained a bright spot, driven by both energy-focused exposures (+$724M) and broad commodities (+$481M), while gold recorded outflows (-$700M).
The broad commodities category logged its 16th month of inflows out of the last 17, as investors seek opportunities to add inflation resilience to their portfolios. October inflows also lifted the year-to-date total to $7.6B, just $528M shy of the previous annual record of $8.1B set in 2021, with 2 months remaining in the year.
Equities: domestic market bias
At the start of October, non-U.S. equity ETFs were capturing roughly 35% of all equity ETF flows—a share above their market weight that signaled investors were seeking greater geographic diversification after years of heavy concentration in U.S. equities.
However, that trend reversed in October, as 80% of all equity flows last month were allocated to U.S. equity exposures.
This aligns with October performance patterns, where the U.S. outperformed the rest of the world following notable declines in Europe and across select emerging markets, such as China and Brazil.
Nevertheless, emerging-market weakness did not stall inflows into the asset class, nor did it reverse the longer-term trend of broader emerging markets outperforming the U.S. over the past 12 months (12% versus 11%).
Emerging-market ETFs logged $4B in inflows in October, marking the 20th month of net subscriptions over the last 21 months. Year-to-date inflows of $56B already represent an annual record. Emerging markets also played a central role in single-country fund flows.
Of the $5.7B allocated to single-country ETFs, Brazil-focused funds captured $3B. These flows likely reflected long-to-lend trades—an example of the multifaceted role ETFs can fulfill—as market participants sought to hedge or short the Brazilian equity market following unexpected election outcomes.
Sectors: Technology versus Energy
A monoculture describes a scenario where a single theme dominates broad segments of society simultaneously. The rise of artificial intelligence and its societal footprint represents a clear monoculture theme. This dynamic is mirrored across this year’s sector flows: October’s $7.4B inflow into technology ETFs lifted 2026 inflows to an industry-leading $66B, representing 70% of all sector flows.
In practice, a monoculture does not imply that secondary themes cease to exist; rather, they operate outside the primary headlines. A monoculture can evolve into a dual-theme dynamic, where multiple dominant trends take root with overlapping drivers.
Investment inflows into the energy sector—a critical segment influenced by the conflict involving Iran and central to powering AI infrastructure buildouts—exemplify this dual narrative: energy ETFs captured nearly $3B in October, lifting year-to-date inflows past $12B. This represents the largest annual inflow recorded for energy ETFs and marks the first positive calendar-year subscription total in 4 years. Given the sector’s historical volatility and with 2 months left in the year, these figures may fluctuate further.
The healthcare sector recorded $2.4B in October inflows—an AI-adjacent sector that entered the earnings season facing modest expectations. Healthcare companies substantially surpassed these targets, delivering the largest positive earnings surprise across all sectors at 13.15%.
Bonds: new month, familiar trends
Fixed-income flows can be parsed into 3 primary drivers: duration, credit, and inflation. In each segment, October dynamics mirrored trends seen throughout the year: a preference for limiting duration risk persisted without abandoning it entirely, evidenced by just $287M flowing into long-term Treasury ETFs; credit-sensitive sectors captured $10B in inflows, supported by economic growth and solid corporate fundamentals; and investors continued building inflation resilience, directing $2.6B into inflation-protected bond ETFs in October, marking the 21st positive month out of the last 22. Year-to-date inflows have reached $16B, the 2nd-highest volume on record behind the $40B peak in 2021.
Outside these 3 core categories, municipal bond ETFs experienced a notable increase in inflows. Monitoring whether this trend sustains will be key, as broad municipal bond performance has not decoupled meaningfully from core aggregate debt.
Active strategies: selective gains
Active ETFs recorded $66B in inflows in October, pushing year-to-date totals to $637B—a fresh record on pace to hit $750B by year-end 2026. However, growth was uneven across active sub-segments.
The “Other” category registered net outflows last month, reversing an earlier trend of record year-to-date inflows. This contraction was driven by an individual money-market vehicle. Excluding that fund, non-traditional strategies outside core equity and fixed-income hierarchies took in $2.1B, demonstrating sustained interest in alternative exposures.
Core strategies dominated flows within traditional active equity and fixed-income ETFs. Meanwhile, diversified derivative income strategies—those avoiding single-stock concentration—drove the non-traditional equity segment. Inflows of $58B in 2026, paired with $49B directed into dividend ETFs, pushed total equity income inflows above $100B, setting a fresh annual record with 2 months remaining in the year.
