Reading American Century Companies Inc’s 13F portfolio
American Century Companies Inc’s $226.3B 13F book is spread across 2,884 reported positions and is broadly diversified — the ten largest names are just 22% of the portfolio.

Its five largest positions are NVDA, GOOGL, AMZN, AAPL and MSFT, led by NVIDIA CORPORATION (NVDA) at 5.4% of the portfolio. The heaviest sector exposure is Technology (25%), then Financial Services (9%).

What a 13F does and doesn’t reveal
A 13F captures only American Century Companies Inc’s long positions in US-listed stocks at a single quarter-end, so it is best read as a lagged snapshot rather than a live portfolio. It won’t show shorts, cash, bonds, or holdings listed outside the US, and it never reveals the price paid or the reasoning behind a trade. The signal is in the pattern over time: which names American Century Companies Inc is building up, trimming, or exiting, and how concentrated the book stays from quarter to quarter.
Frequently asked questions
What is an SEC 13F filing?
A Form 13F is a report that every institutional investment manager with at least $100 million in US-listed securities must file with the SEC within 45 days of each quarter's end. It lists the manager's long positions in US-listed stocks and certain options, with the share count and market value of each. American Century Companies Inc's profile on this page is built directly from those filings.
How current is the 13F data on American Century Companies Inc's page?
It reflects American Century Companies Inc's most recently filed 13F, currently the quarter ending Q2 2026. Because managers have up to 45 days after a quarter closes to file, a 13F is always a slightly lagged view rather than a live portfolio. When American Century Companies Inc files its next quarterly report, this page refreshes automatically.
Can I see American Century Companies Inc's complete list of holdings?
This page highlights American Century Companies Inc's largest positions rather than all 2,884 names in the filing. The complete, position-by-position 13F is public and available from the SEC's EDGAR database under American Century Companies Inc's filings.
Does a 13F show everything American Century Companies Inc owns?
No. A 13F only covers long positions in US-listed stocks and certain options. It leaves out short positions, cash, bonds, commodities, foreign-listed stocks, and private holdings, so it is a partial view of American Century Companies Inc's book rather than its full strategy or total assets.
Is 13F data investment advice?
No. Everything here is educational. 13F positions are disclosed with a delay, cover only long US-listed holdings, and never explain why American Century Companies Inc made a trade or at what price. Treat it as a research lens, not a recommendation, and speak with a licensed financial advisor before making investment decisions.
Not investment advice. Holdings data comes from public SEC Form 13F filings, which are filed with a delay of up to 45 days and may be amended later. It describes historical, disclosed positions in US-listed securities only, meaning no shorts, cash, or foreign holdings, and it is not a recommendation. Always do your own research and speak with a licensed financial advisor before making investment decisions.
