Asset Class Flows: Equities Dominate, Crypto Surges

Equities led the charge with $18.1bn of inflows, extending a strong September start as investors repositioned toward large-cap benchmarks and growth sectors.

Fixed income funds followed with $9.6bn, showing that demand for credit and municipals remains intact even as interest rate expectations stay uncertain.

Commodities added $271m, while cryptocurrency ETPs surged by $1.46bn, a clear sign that risk sentiment has improved across asset classes.

Sector Trends: Tech Inflows, Materials Outflows

At the sector level, technology stood out with more than $1bn in inflows and a 3.1% gain on the week, supported by renewed momentum in AI and mega-cap names.

Industrials and consumer discretionary also attracted fresh allocations, while utilities gained 2.3% but drew only modest interest.

By contrast, financials bled $577m despite posting a 1.3% rise, and materials lost $367m in flows even as the sector delivered the strongest weekly return at 4.1% — a disconnect suggesting profit-taking in cyclical names.

Regional Rotation: U.S. Leads, Asia Outperforms

Regional allocations were led by U.S. equity funds, which took in $6.0bn.

Developed markets added $3.9bn, while global “world” ETFs gathered $1.6bn.

Emerging markets also benefitted, with $1.0bn of inflows led by China, which attracted $145m and returned 4.6%.

Performance was strongest in South Korea, up 7.1%, followed by South Africa (+4.9%) and Taiwan (+4.3%), highlighting the rebound in Asian equities.

Thematic ETFs: Internet, Crypto, and Hydrogen Shine

Thematic flows told a similar story of renewed risk appetite. Cryptocurrency ETFs dominated with $1.45bn of net new money, their best week since the summer.

Next Generation Internet theme followed closely with $1.0bn, while fintech, smart city, and AI strategies all saw healthy inflows.

On the performance side, the hydrogen economy theme soared 11.3%, blockchain gained 10.2%, and defense-linked strategies also delivered strong weekly returns.

Fixed Income ETFs: Credit Back in Focus

Bond ETFs saw steady and broad-based allocations. Investment-grade aggregate funds pulled in $2.6bn, municipals added $1.4bn, and high-yield corporates gained $698m.

Government bond ETFs gathered nearly $900m, though flows leaned away from sovereigns and toward credit risk, underlining investors’ preference for yield over safety.

Commodities: Gold Shines, Silver Struggles

Commodities were dominated by gold, which absorbed $337m, extending its role as the preferred hedge in volatile markets.

Platinum ETFs gained $42m, while silver funds shed $141m, pointing to a more selective demand for precious metals.

Crypto ETFs: Bitcoin Drives the Comeback

Cryptocurrencies were once again headline-grabbing. Bitcoin funds took in a massive $1.6bn, dwarfing the $191m outflow from ether products.

Solana and XRP each added smaller but notable inflows of $27m and $18m, respectively, underscoring investor willingness to diversify beyond the two largest tokens.

Standout Products: Vanguard VOO Breaks Records

Among single products, the Vanguard S&P 500 ETF (VOO) dominated the leaderboard with an extraordinary $32.4bn of inflows, one of the largest weekly hauls on record.

The ARK Innovation ETF (ARKK) followed with $3.2bn, while the iShares Russell 2000 ETF (IWM) brought in just over $2bn. International exposure was fueled by the iShares Core MSCI EAFE ETF (IEFA), which gathered $1.9bn.

On the bond side, the iShares J.P. Morgan USD Emerging Markets Bond ETF (EMB) added $787m, while the Vanguard Total Bond Market ETF (BND) pulled in $730m.

Crypto allocations were led by the iShares Bitcoin Trust ETF (IBIT, $720m) and Fidelity Wise Origin Bitcoin Fund (FBTC, $538m), while gold exposure came through the iShares Gold Trust (IAU, $570m).

Performance Leaders: Crypto Miners Surge

Performance was dominated by crypto-linked products. The Valkyrie Bitcoin Miners ETF (WGMI) surged 26.7%, while the Global X Blockchain ETF (BKCH), Schwab Crypto Thematic ETF (STCE), and Grayscale Bitcoin Miners ETF (MNRS) all returned over 21%.

Other top performers included leveraged Solana and blockchain products, underscoring the speculative risk-on tone of the week.

Issuer Flows: Vanguard Soars, iShares Bleeds

At the issuer level, Vanguard was the undisputed leader last week, adding $38.6bn, followed by Ark Investment at $4.7bn. Invesco and Fidelity also posted inflows above $1bn each. Meanwhile, iShares endured a bruising week, losing $23.3bn, with SPDR ETFs shedding nearly $2bn.
