The Philadelphia Semiconductor Index has surged about 64% since late March, including a 5.5% jump last Friday, as AI infrastructure trades remained the main engine of the broader stock rally.
Intel led the latest burst, spiking nearly 14% Friday after reports it will build chips for Apple; its Q1 non-GAAP EPS beat estimates at $0.29 versus $0.01, while Data Center and AI revenue rose 22% to $5.05 billion.
AMD and memory names added momentum: AMD's Data Center revenue climbed 57% to $5.78 billion and its Q2 revenue outlook is about $11.2 billion, while SanDisk jumped nearly 17% after reporting sales up 251% to $5.95 billion.
The rally has been unusually concentrated—information technology rose 2.58% Friday, no other sector gained even 0.6%, five of 11 S&P sectors fell, and only 52% of S&P 500 stocks trade above their 50-day averages.
Capital is also spreading beyond equities into AI financing, with Apollo and Blackstone weighing $35 billion for Broadcom, whose AI semiconductor revenue doubled to $8.4 billion and is projected to reach $10.7 billion in Q2.
