Capital World Investors 13F: Q2 2026 Portfolio — $846.43B Across 637 Positions

In Q2 2026, Capital World Investors’ changes add up to a targeted rotation inside large-cap exposures rather than a broad de-risking. The top weight remains concentrated in Broadcom via an add to AVGO at 5.44% of the portfolio, while Alphabet exposure is reinforced through adds to Alphabet (3.1%) alongside a separate trim in Alphabet at 1.77%. Share action is also mixed in other mega-platform holdings: Tesla was added (2.27%), while Nvidia (2.58%) and Microsoft (2.43%) were trimmed.

The portfolio also shows sharper selectivity in semiconductors and adjacent tech. Micron Technology at 4.02% saw a sizeable trim with shares down 29.9% on the quarter, whereas Taiwan Semiconductor Manufac was added (1.94%) with shares up 4.5%. Across the broader book, activity is heavy—291 adds versus 199 trims—with 75 new positions and 58 exits—suggesting a willingness to refresh holdings while keeping concentration meaningful, with top-10 weight at 29.6%.

New entries span niche tech and healthcare themes, including Arm Holdings, Rocket Cos, and Cerebras Systems, while exits include Tractor Supply and Ametek. The quarter’s moves, particularly the juxtaposition of adding to AVGO and GOOGL while trimming MU and NVDA, point to an internal rebalance toward select large-cap compounders and away from specific high-conviction positions within semis.

A Form 13F is a quarterly snapshot institutional managers with over $100M in US-listed assets must file within 45 days of quarter end. It shows long equity positions only: no short book, no cash, no non-US listings, no timing inside the quarter. Treat it as a delayed map of where the manager's conviction sat on the reporting date — not a live portfolio, and not a buy list.
