2026-Q2 Capital World Investors 13F Filing: Capital World trims MU even as its value jumps to $34.02B

This is Capital World Investors' Form 13F filing for 2026-Q2, covering the quarter ended June 30, 2026 and detailing the firm's U.S. equity holdings and quarter-over-quarter position changes.

Quick Reference

Q: What is Capital World Investors' biggest holding after its 2026-Q2 13F filing? Broadcom (AVGO) is Capital World Investors' largest single stock position after the June 30, 2026 filing, accounting for 5.44% of the portfolio. The fund actively added to the stake during the quarter, and its market value reached $46.04B, up from $35.96B at the end of March.

Q: Did Capital World Investors buy or sell Micron (MU) in Q2 2026? Capital World Investors sold Micron shares during the quarter -- the jump in the position's dollar value came from the stock's price rally, not from buying. The filing itself notes that shares were trimmed (real selling) but the dollar value rose because the stock price gained more than the trimmed shares were worth. As a result, MU's reported value climbed from $14.21B to $34.02B, lifting its portfolio weight from 1.94% to 4.02%.

Q: Which semiconductor stocks did Capital World Investors add in Q2 2026? Among the quarter's top moves, the fund added to four semiconductor positions: Broadcom (AVGO), KLA (KLAC), Western Digital (WDC), and Taiwan Semiconductor (TSM). KLAC posted a change of +$7.66B, taking its weight from 0.82% to 1.61%, while WDC moved +$7.39B (from 0.44% to 1.25%) and TSM +$5.30B (from 1.52% to 1.94%).

Q: Did Capital World Investors buy or sell Alphabet in Q2 2026? Both, depending on the share class: Capital World Investors added to Alphabet's GOOGL (Class A) shares while trimming its GOOG (Class C) shares. GOOGL recorded a change of +$7.42B, with its weight rising from 2.56% to 3.10%. The GOOG trim was genuine selling, yet its dollar value still rose from $12.84B to $15.00B because the share price gained more than the trimmed shares were worth.

Q: What did Capital World Investors sell or trim the most in Q2 2026? Netflix (NFLX) took the largest dollar-value hit among the fund's active sells, recording a change of -$3.29B as its weight fell from 1.30% to 0.74%. Other notable reductions included Microsoft (MSFT, a change of -$2.28B), Comcast (CMCSA, -$2.66B), Northrop Grumman (NOC, -$2.12B), AT&T (T, -$1.95B), L3Harris (LHX, -$1.88B), Capital One (COF, -$1.83B), and Salesforce (CRM, -$1.76B).

Q: Why did the value of some stocks Capital World Investors trimmed go up anyway? Because the share prices of those stocks rose by more than the value of the shares sold -- the filing explicitly flags this for Micron (MU), Intel (INTC), ASML (ASML), CVS Health (CVS), Philip Morris (PM), and Alphabet's GOOG shares. In each case the share count genuinely fell, but price appreciation exceeded what the trimmed shares were worth, so the reported dollar value increased. Philip Morris is the clearest example: its value moved from $22.06B to $24.09B even as its weight slipped from 3.01% to 2.85%.

Q: Did Capital World Investors add to health care stocks in Q2 2026? Yes -- the fund actively added to UnitedHealth (UNH) and Eli Lilly (LLY) during the quarter. UNH recorded a change of +$4.91B, lifting its weight from 1.03% to 1.47%, while LLY moved +$4.71B, from 1.96% to 2.25%.

Q: How did Capital World Investors' sector allocation change in Q2 2026? Information Technology widened its lead as the fund's largest sector, rising to 28.52% of the portfolio from 22.62% the prior quarter. Financials slipped to 9.94% from 11.19%, Communication Services eased to 9.73% from 10.93%, and Health Care held nearly steady at 13.39% versus 13.21%.

Q: What new position did Capital World Investors open in Q2 2026? The filing shows a single new buy, reported under CUSIP 02079K404, valued at $1.88B and equal to 0.22% of the portfolio. The holding is identified by its CUSIP number rather than a company name in this filing data.

Q: How many stocks does Capital World Investors hold after its 2026-Q2 filing? Capital World Investors held 637 positions as of June 30, 2026, up from 620 the prior quarter. Its turnover ratio came in at 0.286529, down from 0.310144 three months earlier, marking a modestly slower pace of trading.

Q: What's the easiest way to track Capital World Investors' future filings? Check Capital World Investors' next quarterly 13F filing, which will cover the quarter ending September 30, 2026 and reveal the fund's latest buys, sells, and position sizes. U.S. institutional managers must file a 13F within 45 days of each quarter's close, so a fresh report arrives roughly six weeks after every quarter ends.
