Capital World Investors turned over 41 positions in Q4 2025 — opening new names, exiting others — while leaving their Broadcom-led core completely intact. The $735B division refreshed the periphery without disturbing the thesis.
This is what active management looks like at scale: high turnover at the edges, zero turnover at the core.
The filing
| Metric | Value |
|---|---|
| 13F AUM | $735B |
| Positions turned over | 41 (new opens + exits) |
| Core unchanged | AVGO at #1, mega-cap top-5 stable |
| Filer | Capital World Investors (Capital Group) |
The core-periphery architecture
Capital World's portfolio has two distinct layers:
The immovable core
- Broadcom (AVGO): #1 position, unchanged
- Microsoft, Meta, NVIDIA, Alphabet: Top 5, stable weights
- These positions represent the long-term research thesis
- No trimming, no adding — just holding
The active periphery
- 41 positions turned over in one quarter
- New names entering, old names exiting
- This is where the research team expresses fresh views
- Higher turnover = more active idea generation at the edges
The pattern
Core (stable): AVGO | MSFT | META | NVDA | GOOGL — untouched
Periphery (active): 41 positions rotated — new research ideas cycling in and out
Why 41 turnovers with a stable core matters
1. It reveals where conviction lives
If the core is stable while the periphery churns, the research team's highest-conviction ideas are in the top 5-10 names. The peripheral positions are more tactical — sector rotations, catalyst-driven entries, risk management adjustments.
2. It separates strategic from tactical
- Strategic positions (core): Held for quarters or years, based on long-term secular themes (AI infrastructure, cloud, digital advertising)
- Tactical positions (periphery): Held for 1-2 quarters, based on near-term catalysts or valuation opportunities
3. It shows the research engine is active
41 turnovers at a $735B fund means the 350-analyst research team is continuously generating and retiring ideas. The fund isn't on autopilot — the periphery is constantly refreshed while the core compounds.
The Broadcom stability signal
Broadcom remaining at #1 through a quarter of significant portfolio activity is the loudest signal in the filing:
- 41 other positions changed. AVGO didn't.
- The research team reviewed the entire portfolio. AVGO stayed.
- Capital World had every opportunity to trim into strength. They chose not to.
Stability at the top during active peripheral management = maximum conviction in the core thesis.
How this compares to other approaches
| Manager | Core stability | Peripheral turnover | What it means |
|---|---|---|---|
| Capital World | Very stable | High (41/quarter) | Active periphery, convicted core |
| Berkshire | Extremely stable | Very low | Buy and hold everything |
| AQR | No stable core | Total reconstruction | Factor-driven, no conviction positions |
| Bridgewater | Shifting | High (290 in Q4) | Macro-driven, everything is tactical |
Capital World sits between Berkshire's total stability and AQR's total turnover — maintaining strategic core positions while actively managing the rest.
What the 41 turned-over positions might include
Without the specific names (from the full filing), common patterns for Capital Group peripheral turnover include:
- Sector rotation entries: Adding financials (BAC) and industrials (CAT) as seen in Capital International's filing
- Catalyst-driven exits: Removing names where the thesis played out or failed (like Disney in Capital International)
- Valuation-driven swaps: Replacing expensive names with cheaper alternatives in the same sector
- New IPO/spin-off additions: Entering recently public companies after initial research
What to watch next quarter
- Is AVGO still #1? Continued stability = multi-quarter conviction confirmation
- Turnover rate: Was 41 typical or elevated? Compare to prior quarters
- What entered the periphery: The new names reveal Capital World's emerging research themes
- What exited: The exits reveal where conviction expired
- Cross-division check: Did Capital International and Capital Research Global show similar peripheral turnover patterns?
