Four Whale Funds Put More Than $138B Into Broadcom In Q4 2025
Broadcom remained the clearest single-stock anchor across several major 13F portfolios in 2025Q4. The weight, not just the dollar total, explains why AVGO kept showing up at the top of institutional books.
Broadcom was not just another mega-cap winner in 2025Q4. It was an institutional anchor. Across four major managers, disclosed Broadcom exposure totaled $138.05B. More important than the dollar total, however, was the role Broadcom played inside each portfolio. At Capital International Investors, it reached 7.70% of assets. At Capital World Investors, it still stood at 5.80%. Even funds that did not make it the largest single position still treated it as a top-tier core holding.
- Largest dollar holder: Capital International Investors disclosed $49.10B of Broadcom.
- Highest portfolio weight: Broadcom reached 7.70% of assets at Capital International.
- Most diversified use: Wellington held Broadcom at a lower 3.05% weight, but still at a meaningful $16.40B.
- What stands out: Broadcom kept winning capital even in portfolios that were also heavily exposed to Microsoft, Nvidia, Apple, and Amazon.
Why Broadcom Stood Out In A Crowded Mega-Cap Field
Institutional managers had no shortage of liquid ways to express the AI and infrastructure theme in 2025Q4. They could lean into Microsoft for enterprise software and cloud, Nvidia for compute leadership, Apple for platform durability, or Amazon for cloud scale. Broadcom still kept commanding top-tier capital because it offered a different mix: infrastructure exposure, high-margin software, and a balance-sheet profile large funds could own at scale.
That is why the weighting data matters so much. A stock can appear in every large portfolio without being particularly informative. Broadcom crossed the line into real signal because it repeatedly showed up as one of the largest individual positions, not merely as a background holding.

The Weight Tells You More Than The Dollar Total
A $49.10B position is visually impressive, but the better question is how much of the portfolio it controlled. In that respect, Capital International was the strongest statement at 7.70%. Capital World and CRGI also kept Broadcom above 5.5% of assets, which is high enough to define the book's tone. Wellington used Broadcom more conservatively, but still at a size most managers would consider core.
That spread tells you Broadcom was adaptable. For some funds it was a conviction anchor. For others it was a major but still shared pillar inside a broader mega-cap basket. Either way, it remained too important to ignore.

Broadcom Was The Common Language Across Different Strategies
The cross-fund comparison is the most useful part of the exercise. Capital World rotated heavily below the surface while preserving Broadcom at the top. Capital International kept Broadcom as the portfolio's clearest anchor while adding new exposures elsewhere. CRGI paired Broadcom with a major Netflix buildout. Wellington kept AUM nearly flat while still giving Broadcom a large permanent seat in the book.
That is what makes Broadcom different from a temporary market favorite. The stock was not only rising. It was functioning as a shared institutional language that supported multiple portfolio construction styles.

What Investors Should Learn From This
When a stock repeatedly ranks near the top of multiple large active portfolios, the right question is no longer whether the market likes it. The better question is why it can carry that much capital across different mandates at the same time. Broadcom passed that test in 2025Q4.
For retail investors, the practical takeaway is not to mimic the position blindly. It is to treat Broadcom as a stock that mattered to institutional construction, not just institutional performance. That distinction matters when you decide which names deserve deeper follow-up work after filing season.
Questions Investors Are Likely To Ask
Why was Broadcom such a common top holding?
Because it offered liquid, scalable exposure to AI infrastructure and software economics in a single large-cap vehicle.
Which fund showed the strongest conviction?
Capital International Investors showed the strongest weight-based conviction with Broadcom at 7.70% of assets.
Why compare weights instead of only dollars?
Weights show how much a stock truly matters inside a portfolio, which is more informative than a raw dollar figure on its own.
Does overlap across funds weaken the signal?
No. In this case it strengthens it, because Broadcom remained a top-tier position across different portfolio styles rather than only one narrow strategy.
