Fall back, and look forward ETF flows show markets recalibrating
October ETF flows show record bond inflows, a renewed US equity bias, and strong Technology and Energy demand.
For parents, daylight saving time is less about gaining an hour and more about navigating the adjustment. The clocks change instantly, except for the microwave, which is always last on the list.
Yet your internal clock, and more importantly, your kids’ internal clocks, don’t change with them. Bedtime suddenly feels too early, wake-up time feels too late, and for a few days the household routine is completely out of sync.
Markets go through similar periods of recalibration. A new inflation report, a change in monetary policy, an earnings surprise, or a geopolitical shock can alter the market environment almost immediately. Investors then need to determine whether that new information represents just a temporary disruption or something important enough to reset expectations around growth, inflation, and interest rates.
So, did ETF flows fall back in October or spring ahead to more records amid the latest market recalibration?
Bond rally sparks big bond flows
Following their worst monthly return in over four years, broad core bonds had their best monthly return in over three years, rallying by more than 2.4% in October.1 Right as this reversal occurred, bond ETFs recorded their greatest monthly inflow ever: $74 billion. October also marked a record sixth consecutive month with more than $50 billion of inflows. Before this year, bond ETFs had never recorded even one $50 billion-plus month
The strong October haul, along with that trend of $50 billion-plus months, pushed fixed income ETF inflows to over $542 billion year to date with flows headed for $660 billion by the end of the year (based on my projections). These inflows have come from a more balanced mix of low-cost and active bond ETFs. That’s a departure from prior years, when low-cost had a firmer grip on the flow share, as the use of active bond ETF strategies has grown within portfolios (Figure 1).
From a tactical perspective, bond inflows reflected three key themes, with October trends largely consistent with those seen throughout the year:
Duration: Investors once again preferred to limit duration risk, though not eliminate it completely. They remained reluctant to significantly extend duration in an environment where rates might stay higher for longer, as evidenced by just $287 million going into long-term government bond ETFs. Meanwhile, short-term government bond funds led government-based maturity flows with $7.1 billion in October.
Credit: Credit-related sectors registered $10 billion of inflows, as solid fundamentals and economic growth continued to support credit risk. Inflows were led by investment-grade corporate bond ETFs (+$9.3 billion) and high yield bond ETFs (+$2 billion).
Inflation: With recent inflation data still showing stubborn price pressures, investors continued to seek ways to build inflation resilience into portfolios. Inflation-linked bond ETFs had $2.6 billion of inflows in October, marking their 21st month of inflows in the past 22.

Equity flows show a home bias
Heading into October, non-US equity ETFs were taking in roughly 35% of all equity ETF flows, a share above their market weight and indicative of investors seeking greater geographic diversification after years of concentrating in US equities. That trend ended in October, when 80% of all equity flows went into US equity exposures.
This does rhyme with performance trends in October, as the US beat the rest of the world because of notable drawdowns in Europe and certain areas of emerging markets (EM), such as China and Brazil. But weakness in EM didn’t stop inflows into the category. Nor did it overturn the longer-term performance trend: Broad EM returned 12% over the past year, compared with 11% for the US.2
EM ETFs had $4 billion of inflows in October, the 20th month in the past 21 in which they recorded inflows. Year-to-date inflows of $56 billion are already an annual record. EM also played a role within single-country fund flows.

Energy and Tech lead sector flows
A monoculture refers to a state in which a single topic dominates large segments of society at the same time. The rise of AI and its impact on society is an example of a monoculture topic. And it shows in sector flows this year, as Technology ETFs’ $7.4 billion of inflows in October pushed 2026 flows to a leading $66 billion—70% of all sector flows.
A monoculture doesn’t mean that all other cultural topics and trends disappear. Sometimes, it gives way to a dual narrative as another dominant topic with overlapping threads takes hold.
Energy, a key sector affected by the war in Iran and central to powering the AI infrastructure buildout, represents that second narrative. Energy sector ETFs took in nearly $3 billion in October, pushing year-to-date inflows to over $12 billion. That’s the most Energy ETFs have ever taken in during a single year, putting the sector on track for its first positive calendar year in four years.
In fact, Technology and Energy made up 100% of the $10 billion of inflows into sectors. Five sectors had outflows and only one other sector had inflows over $1 billion.

Look ahead as the clocks fall back
October provided another reset of the market’s internal clock. The return of earnings season shifted attention from macro-heavy news back to fundamentals, but it also exposed a changing hurdle for the market’s biggest growth engine as the focus shifts from building AI to monetizing it. Spending alone may no longer be enough.
Meanwhile, the macro forces that have complicated the market’s schedule haven’t gone away. Moving the hands on the clock doesn’t change the season outside, and flipping the calendar from 2026 to 2027 won’t make AI, inflation, fiscal deficits, geopolitical fragmentation, or higher rates disappear.
What can change is how and where investors experience them. For AI, the opportunity could broaden from companies building the infrastructure to those using it to improve productivity. In fixed income, elevated yields offer meaningful income, but persistent rate pressure argues for focusing on short-duration exposures. And because inflation and macro shocks can pressure stocks and bonds simultaneously, broader diversification can help build portfolio resilience.
Big picture, both the calendar and the clock have changed, but the underlying fundamental and macro forces haven’t. So, while the clocks may fall back, investors need to keep looking forward by broadening their portfolios’ sources of return, being deliberate about risk, and diversifying across growth and inflation outcomes.
