Capital World Investors' $735B Portfolio Bets on Broadcom Over NVIDIA — and Philip Morris Over Amazon

Every other mega-filer leads with NVIDIA. Capital World Investors — the equity arm of Capital Group, one of the world's largest active fund managers — leads with Broadcom. At $42.7 billion and 5.80% portfolio weight, Broadcom outranks NVIDIA ($24.4B) by nearly $20 billion. And the surprises don't stop there: Philip Morris International at #5 ($21.2B) ranks above Amazon, which barely cracks the top 15 at $7.8B. With only 574 positions in a $735 billion portfolio, this is what concentrated conviction looks like — and it looks nothing like the rest of Wall Street.

TL;DR

• AUM: $735.3 billion (+0.4% QoQ, +11.6% YoY) — the world's largest active-only stock picker by 13F assets
• Only 574 positions: Average position size of $1.28 billion — compared to Morgan Stanley's $207M average across 8,095 positions
• Broadcom #1 at $42.7B: The only mega-filer to rank AVGO above NVDA — a bet on custom AI chips over GPUs
• Philip Morris #5 at $21.2B: Tobacco/IQOS in the top 5 is unique — no other mega-filer carries PM this high
• Micron #8, Vertex #10: Memory chips and biotech earning top-10 slots is highly differentiated
• Amazon at #15: $7.8B (1.06%) — a fraction of what peers hold, signaling CWI's view that AMZN is fairly valued
• Meta retained: $26.1B at #3 — while every other mega-filer trimmed, CWI barely reduced Meta
• No ETFs, no index funds: Pure stock picking — every position is an individual equity

Broadcom Over NVIDIA: The Custom Chip Thesis

Broadcom at #1 with $42.7 billion is Capital World Investors' defining position. Among the seven mega-filers analyzed this quarter — FMR, Morgan Stanley, JPMorgan, Goldman Sachs, Susquehanna, Northern Trust — every single one has NVIDIA as the top tech holding. CWI is the outlier.

The thesis is clear when you look at what Broadcom actually does: it designs custom AI accelerators (TPUs for Google, inference chips for Meta), dominates networking silicon for AI data centers, and owns VMware's enterprise software franchise. CWI's bet is that as AI moves from training (NVIDIA's strength) to inference and deployment (Broadcom's sweet spot), the value chain shifts. At $42.7B versus NVIDIA's $24.4B, CWI is placing a 1.75x overweight on this thesis.

Philip Morris at #5: The Contrarian Conviction That Defines CWI

Philip Morris International (PM) at $21.2 billion (2.89%) is the filing's most distinctive position. No other mega-filer ranks a tobacco company in their top 5. For context, CWI's Philip Morris position is larger than its Amazon position ($7.8B) by nearly three times.

The thesis centers on IQOS, Philip Morris's heated tobacco device that has transformed the company from a declining cigarette business into a growth story. IQOS now generates over 35% of Philip Morris's net revenue, and the product's recent U.S. market authorization creates a new growth runway. CWI is effectively betting that Philip Morris at 18x earnings with a 4%+ dividend yield and IQOS growth is a better risk/reward than Amazon at 35x with margin compression risk from AI infrastructure spending.

574 Positions: The Power and Risk of Concentration

Capital World Investors holds 574 positions — roughly 7% of Morgan Stanley's 8,095 or Fidelity's 5,359. The average position size of $1.28 billion means every holding represents a meaningful allocation decision, not a rounding error.

This concentration cuts both ways. When CWI's bets work (Broadcom is up 70%+ over the past year), the portfolio compounds aggressively. When they don't (Q1 2025 saw a -6.4% drawdown, worse than most diversified peers), the pain is concentrated too. CWI's Q4 near-flat performance (+0.4%) likely reflects some mean reversion after the strong Q2-Q3 run, with its top positions trading sideways.

The Meta Anomaly: CWI Bucks the Institutional Selling Wave

Meta Platforms at $26.1 billion (3.55%) and #3 is one of the most interesting data points in the filing. While Fidelity cut $4.3B, JPMorgan slashed 28%, Goldman cut 22%, and Morgan Stanley trimmed 8% — CWI's reduction was only 9.4%, the mildest trim among any mega-filer.

Capital Group has historically been one of Meta's largest and most patient institutional holders. Their willingness to hold through the Reality Labs spending cycle (when others rotate to Alphabet) suggests CWI's fundamental analysts see value in Meta's advertising business that the market is discounting due to metaverse overhead. Whether this patience is rewarded depends on whether Meta can deliver on its AI advertising optimization promises.

Micron and Vertex: The Hidden Conviction Bets

Micron Technology (MU) at $16.6 billion (#8, 2.26%) and Vertex Pharmaceuticals (VRTX) at $11.6 billion (#10, 1.57%) are positions you won't find in any other mega-filer's top 10. Micron is a bet on AI memory demand — HBM (High Bandwidth Memory) chips are critical for AI accelerators, and Micron is one of three global suppliers. Vertex is a cystic fibrosis treatment leader expanding into pain management and gene editing.

These positions showcase CWI's research-driven approach: rather than owning the Magnificent Seven like everyone else, Capital Group's analysts are building concentrated positions in the companies they believe offer the best risk-adjusted returns, regardless of index weight.

Where Is Amazon? The $7.8B Underweight

Amazon at $7.8 billion (1.06%) barely makes CWI's top 15. For perspective, JPMorgan holds $36.9B in Amazon, Fidelity holds $76.5B, and even Goldman holds $17.6B. CWI's relative underweight is one of the most aggressive anti-consensus bets in the filing — it implies CWI's analysts believe Amazon's margin story (AWS vs. retail drag) doesn't justify the premium multiple when better opportunities exist elsewhere (Broadcom, Philip Morris, Micron).

From $383B to $735B: The Active Manager's Recovery

CWI's AUM has nearly doubled from its $383 billion Q3 2022 trough to the current $735 billion — an 92% increase driven primarily by stock selection alpha rather than broad market beta. The concentrated portfolio amplifies both gains and losses relative to diversified peers, which is why CWI's growth trajectory is lumpier than Northern Trust's or Morgan Stanley's smoother curves.

It manages several American Funds, the largest actively managed mutual fund family in the U.S. The 13F consolidates holdings across all Capital World-managed products.

Why does Capital World rank Broadcom above NVIDIA?

Broadcom (AVGO) is CWI's #1 holding at $42.7B versus NVIDIA's #4 at $24.4B. CWI appears to be betting on the transition from AI training (NVIDIA's GPUs) to AI inference and deployment (Broadcom's custom accelerators, networking chips, and VMware software). This is a differentiated, high-conviction thesis not shared by any other mega-filer.

Why is Philip Morris in the top 5?

Philip Morris International (PM) at #5 ($21.2B) reflects CWI's conviction in the IQOS heated tobacco transformation story. With 35%+ of revenue from IQOS and a recent U.S. market authorization, CWI sees PM as a growth-at-a-reasonable-price play with a 4%+ dividend yield as downside protection.

How many positions does Capital World hold?

Only 574 positions — the fewest among any mega-filer. This translates to an average position size of $1.28 billion, making every holding a meaningful, research-driven conviction bet rather than an index-filling allocation.

What is Capital World's WhaleScore?

Capital World Investors has a WhaleScore of 75.50 — tied with FMR LLC as the highest among all mega-filers analyzed, reflecting its massive AUM, filing consistency, and concentration.
