Understanding the 13F Disclosure

13F filings represent mandatory quarterly reports filed with the SEC by institutional investment managers overseeing at least $100 million in qualifying securities. These documents snapshot holdings at the conclusion of each quarter.

AMD’s latest filing captured its portfolio composition as of March 31, 2026. While the Marvell investment represents a modest position in absolute terms, it attracted considerable attention given both companies’ prominence in the semiconductor industry.

The Xanadu Quantum Technologies stake marked a fresh entry in AMD’s publicly disclosed investment portfolio, carrying an approximate value of $1.5 million at the filing date.

MRVL finished its previous trading session prior to the filing’s public release, then experienced upward price movement in premarket hours once AMD’s ownership stake became widely known.
