Capital World Investors’s portfolio moves, tracked quarter by quarter. This profile follows the institutional investor’s Form 13F disclosures over time, giving a running record of new positions, exits, and adjustments as they are reported to the SEC. Because 13F filings only reveal a snapshot of holdings at quarter-end, this page will be refreshed with each new filing cycle rather than treated as a one-off news post.
A quick note on how to read these updates: Form 13F filings disclose quarterly snapshots of U.S. equity holdings, not the exact date a trade happened. So rather than pinpointing a single day, each entry here is tied to the quarter it was reported in, for example the quarter ending 2026-03-31, referenced below.

What this quarter’s activity shows
Taken together, this filing period is defined almost entirely by fresh entries rather than exits or trims, with the fund establishing stakes across a broad mix of industries including semiconductors and networking, airlines, pharmaceuticals, defense and industrials, energy, and consumer retail. No reductions, closures, or share-count increases to existing positions were disclosed for this quarter in the data reviewed here.
This page exists as an ongoing reference rather than a single snapshot, so future quarters will be layered on top of this foundation as new 13F filings become available. Readers tracking institutional ownership trends, in the way many follow well-known filers, can check back here each quarter for updated figures.
