ADVANCED MICRO DEVICES INC

The mega-holders (top 5):

• BlackRock, Inc.: $29.7B (12.4% of AUM, 145.8M shares, -1.2% shares, -$1.9B from $31.7B) -- the largest holder, slight trim.
• Vanguard combined (3 entities): Vanguard Capital Management LLC ($21.6B, 105.9M shares, NEW) + Vanguard Portfolio Management ($7.6B, 37.6M shares, NEW) + Vanguard Fiduciary Trust ($1.9B, 9.3M shares, NEW) = $31.1B combined -- makes the Vanguard block the single largest institutional owner when aggregated, though split across three reporting IDs.
• State Street Corp: $15.2B (6.4%, 74.8M shares, -0.2%, -$834M) -- third largest.
• FMR/Fidelity: $7.6B (3.2%, 37.4M shares, NEW reporting entity? Actually the data shows FMR as 15.3M shares / $3.1B at +6.8%; the $7.6B figure in new positions appears to be a different Fidelity entity). Let me re-read: FMR LLC in topHolders is $3.1B (15.3M shares, +6.8%); Vanguard Fiduciary Trust $1.9B is new. The $7.6B 'new' in the newPositions section is actually Vanguard Portfolio Management. Fidelity split is: FMR LLC appears at $3.1B (listed in topHolders). No $7.6B Fidelity in current top-20 -- the $7.6B was a misread; it's Vanguard Portfolio Management.
• Jane Street Group (market_maker): $11.6B (4.9%, 57.1M shares, +34.6%, +$2.5B from $9.1B) -- fourth, the largest buyer.
• Susquehanna International Group (market_maker): $9.8B (4.1%, 48.1M shares, +14.0%, +$748M) -- fifth, major buyer.
