# Wells Fargo's $549B Q4 2025 Filing Built an ETF Fortress: SPY, IVV, QQQ, and ITOT Control 9.7% of the Book

> Wells Fargo's Q4 2025 13F shows $549.1B across 6,616 holdings. Four ETFs (SPY, IVV, QQQ, ITOT) account for $53.8B — a 9.7% allocation to index wrappers that dwarfs the individual stock positions below.

Wells Fargo filed its Q4 2025 13F showing $549.1 billion across 6,616 unique holdings. The filing's signature: four ETFs in the top 10 controlling nearly 10% of the portfolio. SPY ($19.7B), IVV ($12.9B), QQQ ($11.4B), and ITOT ($9.5B) combine for $53.5B — more than any individual stock in the book. TL;DR AUM: $549.1B (Q4 2025), up 4.4% from $526.0B (Q3) Holdings count: 6,616 unique positions Top holding: SPY ETF at 3.58% ($19.7B) — not an individual stock ETF fortress: SPY + IVV + QQQ + ITOT = $53.5B (9.7% of portfolio) Largest individual stock: Apple (AAPL) at 3.06% ($16.8B) Vanguard Mid-Cap (VO): $7.8B in top 10 — adding mid-cap beta exposure 4-quarter growth: $440B (Q1 2025) to $549B (Q4 2025) = +24.7% Whale Score: 67.75 The ETF Core: 9.7% in Four Wrappers Wells Fargo's allocation to ETFs is structurally different from most mega-filers. Four index ETFs occupy the top 10: SPY (S&P 500): $19.7B, 3.58% — the single largest position IVV (iShares S&P 500): $12.9B, 2.35% — same index, different wrapper QQQ (Nasdaq-100): $11.4B, 2.08% — tech/growth overlay ITOT (iShares Total Market): $9.5B, 1.73% — total market exposure Combined, that's $53.5B in index beta. Add Vanguard Mid-Cap (VO) at $7.8B and the ETF allocation exceeds $61B (11.2% of the portfolio). This is a wealth management platform using ETF building blocks as the portfolio core, with individual stocks layered around it. Individual Stocks: Apple Leads at 3.06% Below the ETF layer, the individual stock positions are relatively small. Apple at $16.8B (3.06%) is the largest, followed by Microsoft at $16.4B (2.99%) and Nvidia at $13.2B (2.41%). These are effectively the same mega-cap names that sit inside the ETFs — meaning Wells Fargo's effective exposure to AAPL, MSFT, and NVDA is significantly higher than the direct holdings suggest. What Analysts Might Misread Misread #1: “Wells Fargo is underweight Nvidia at 2.41%” The 2.41% is only the direct holding. Add the NVDA weight inside SPY (~6.5%), IVV, QQQ (~8.5%), and ITOT, and the effective Nvidia exposure is likely 4-5%+. Misread #2: “Holding both SPY and IVV is redundant” Different client segments and product structures use different ETFs. SPY has higher liquidity for trading; IVV has a lower expense ratio for buy-and-hold. Both serve distinct purposes in a wealth management platform. Frequently Asked Questions What is Wells Fargo's largest 13F holding? The SPDR S&P 500 ETF (SPY) at 3.58% ($19.7B). The largest individual stock is Apple at 3.06% ($16.8B). Why does Wells Fargo hold so many ETFs? As a wealth management platform, Wells Fargo uses ETFs as efficient building blocks for client portfolios. Four index ETFs (SPY, IVV, QQQ, ITOT) account for 9.7% of the 13F — a deliberate allocation strategy, not accidental duplication. How fast has Wells Fargo's 13F AUM grown? From $440B in Q1 2025 to $549B in Q4 2025, a 24.7% increase in four quarters driven by market appreciation and advisory asset gathering.
