Long-term US funds rebounded sharply in April, gathering $120 billion in new assets as investor risk appetite strengthened and markets priced in improving geopolitical conditions.

US Fund Flows Bounce Back as Risk Appetite Strengthens
Equity Funds Drive the Comeback
Large-Blend and Passive Strategies Lead
The rebound in US equity flows was driven almost entirely by large-blend strategies, which brought in $52 billion–the category’s strongest monthly showing in the past five years. This surge highlights continued investor reliance on broad-market exposure during periods of renewed confidence.
Passive strategies remained dominant, accounting for $76 billion in inflows, while actively managed funds saw $34 billion in outflows. Large-growth active funds alone shed $18 billion, reinforcing the long-term shift toward lower-cost, index-based strategies, particularly during market inflection points.
Large-Blend Whips Up a US Equity Rebound in April
International Equity Extends Its Winning Streak
International-equity funds extended their inflow streak to 12 consecutive months, gathering $26 billion in April despite lingering geopolitical uncertainty. The consistency of flows into international markets suggests that investors continue to prioritize diversification beyond the US.
Emerging markets played a key role in sustaining demand, supported by strong performance, including a 14.4% gain in April and a 44% rise over the past year. These gains helped reinforce investor confidence, positioning emerging markets as a meaningful contributor to global equity allocations.
Navigating Market Volatility Through Fund Flows Data
Bond Flows Lag as Investors Move Up the Risk Curve
Taxable-bond flows remained positive but underwhelming in April, with $38 billion in inflows–one of the weakest monthly totals over the past year. This slowdown reflects a shift in investor preferences away from defensive allocations and toward more return-seeking strategies.
Within fixed income, flows favored higher-yielding and more credit-sensitive segments. High-yield bond funds led all fixed-income categories with nearly $7 billion in inflows, while emerging-markets bond funds rebounded with over $3 billion–their strongest showing in nearly a decade.
Risk-On Rotation Drives Modest Taxable-Bond Inflows
Ultrashort Bond Flows Reverse
In a reversal from March’s record inflows, ultrashort bond funds experienced nearly $3 billion in outflows in April–their first monthly decline since March 2024. This shift underscores declining demand for capital preservation strategies as investor sentiment improved.
Rather than seeking to limit duration risk, investors appeared more willing to reallocate into higher-risk areas of the fixed-income market, aligning with the broader risk-on environment.
Tech Drives Sector Flows — But Not Without Skepticism
Record Inflows Into Technology Funds
Sector equity funds collected more than $18 billion in April, with technology-focused strategies accounting for the majority of that growth. Technology funds alone gathered roughly $15 billion, marking the largest monthly inflow on record.
The surge was driven by continued enthusiasm around artificial intelligence, semiconductors, and related infrastructure, which remain central to investor growth narratives.
Investors Hedge Tech Exposure
Despite strong inflows into technology, investor positioning revealed a more nuanced outlook. Inverse equity funds brought in $4 billion—their largest inflow since early 2023—indicating that some investors were hedging against potential downside in the sector.
At the same time, leveraged equity funds experienced record outflows of more than $17 billion, signaling a pullback from amplified risk-taking. Together, these trends highlight a market environment where investors are participating in upside opportunities while actively managing risk.
ESG Funds See First Inflows in Years
ESG-intentional funds posted their first monthly inflows in nearly three years, bringing in approximately $800 million in April. While modest in absolute terms, the shift marks a meaningful break from a prolonged period of outflows.
The rebound was driven largely by a clean energy infrastructure strategy, reflecting renewed investor interest tied to the growth of artificial intelligence and the energy demands required to support it. Although still early, these inflows may indicate a potential turning point for ESG-focused investments.
How Financial Advisors Can Use Fund Flows Data
Fund flows data offers financial advisors a valuable lens into investor sentiment, helping to inform portfolio positioning, product selection, and client conversations. By tracking where assets are moving, advisors can better understand how peers and the broader market are responding to evolving economic and market conditions.
The April data highlights a clear rotation toward risk assets, with equities regaining leadership and credit-sensitive bond sectors attracting interest. Advisors can use these insights to assess whether client portfolios are aligned with current market trends or if adjustments may be warranted to maintain appropriate risk exposure.
Here’s a look at the fund families with the largest April flows:
More on Fund Flows From Morningstar
Asset flows data in Morningstar Direct enables you to stay current with market trends. It offers a comprehensive, timely picture of the total net assets and estimated net flows across multiple geographical markets as well as organic growth rates for specific markets.
With trusted, comprehensive flows data, you can:
- Monitor broad investor trends
- Perform competitive analysis
- Develop new products
- Market managed investment products
Note: The figures in this report were compiled on Dec. 12, 2025, and reflect only the funds that had reported net assets by that date. The figures in both the commentary and the extended tables are survivorship-bias-free. This report includes both mutual funds and exchange-traded funds but not funds of funds unless specifically stated. It does not include collective investment trusts or separate accounts. Important methodology note: Morningstar computes flows using the standard approach in the industry: Net flow is the estimated change in assets not explained by the performance of the fund. Our method assumes that flows occur uniformly over the course of the month. Adjustments for mergers are performed automatically. When liquidated funds are included, the fund's final assets are counted as outflows. Reinvested dividends are not counted as inflows. We use fund-level reinvestment rates to improve accuracy in this respect. We make ad hoc adjustments for unusual corporate actions such as reverse share splits, and we overwrite our estimates with actual flows if managers are willing to provide the data to us. When possible, Morningstar offsets outflows caused by transfers to other investment vehicles that share an identical mandate since they are not indicative of a change in investor interest.
