# Ameriprise Financial's $443B Q4 2025 Filing Added Lam Research to the Top 12 — a Semiconductor Equipment Signal

> Ameriprise held $442.5B across 4,016 positions in Q4 2025. Lam Research at #11 ($4.0B, 0.90%) stands out — a semiconductor equipment name that rarely appears in wealth management platform top-12s.

Ameriprise Financial filed its Q4 2025 13F showing $442.5 billion across 4,016 unique holdings. The top 10 looks like a standard wealth management platform: mega-cap tech, JPMorgan, iShares. But position #11 catches the eye: Lam Research (LRCX) at $4.0B (0.90%) — a semiconductor equipment name that almost never appears in wealth management platform top-12 listings. TL;DR AUM: $442.5B (Q4 2025) Holdings count: 4,016 unique positions Top holding: Nvidia at 3.97% ($17.6B) Lam Research at #11: $4.0B (0.90%) — rare semiconductor equipment presence IVV at #8: $5.4B iShares S&P 500 — platform ETF allocation Visa at #10: $4.8B (1.09%) — payments/fintech tilt Top-5 concentration: 14.8% — moderate for an advisor platform Whale Score: 67.75 The Lam Research Signal Lam Research makes semiconductor manufacturing equipment — the machines that etch and deposit layers on silicon wafers. At $4.0B across 23.3M shares, this is a meaningful position for a wealth management platform. Most advisors allocate to semiconductors through Nvidia or Broadcom. Having Lam Research in the top 12 suggests Ameriprise's model portfolios include a specific semiconductor capital equipment allocation — a second-derivative AI play. The Advisor Platform Core The rest of the top 12 follows the standard advisor playbook: Nvidia (3.97%), Microsoft (3.59%), Apple (2.80%), Alphabet (2.47%), Broadcom (1.94%), Amazon (1.84%). iShares S&P 500 (IVV) at #8 ($5.4B, 1.22%) provides the passive core that advisors build around. Visa as a Fintech Proxy Visa at #10 ($4.8B, 1.09%) is another distinctive choice. While Visa appears in many 13Fs, its position at #10 in a 4,016-holding portfolio puts it above many tech names that are larger by market cap. This suggests Ameriprise's model portfolios deliberately allocate to the payments/fintech theme. What Analysts Might Misread Misread #1: “Lam Research at 0.90% is too small to matter” $4.0 billion is $4.0 billion. In a 4,016-position portfolio, making the top 12 at 0.90% means Lam Research is larger than 4,004 other positions. That's a signal. Misread #2: “Ameriprise is just another index-hugger” The IVV allocation at #8 confirms a passive core, but Lam Research and Visa in the top 12 show active tilts layered around it. This is a core-satellite model in practice. Frequently Asked Questions What is Ameriprise Financial's largest holding? Nvidia at 3.97% ($17.6B), followed by Microsoft at 3.59% ($15.9B) and Apple at 2.80% ($12.4B). Why does Ameriprise hold Lam Research in the top 12? Lam Research makes semiconductor manufacturing equipment. Its presence at #11 ($4.0B) suggests Ameriprise's model portfolios include a semiconductor capital equipment allocation — a second-derivative play on AI infrastructure spending. How big is Ameriprise's 13F portfolio? $442.5 billion across 4,016 unique positions as of Q4 2025. Ameriprise manages wealth advisory assets for individual investors through its advisor network.
