$GlobalFoundries(GFS.US), $Celestica(CLS.US) fell 7 to 10 points, $TTM Tech(TTMI.US), $Penguin Solutions(PENG.US), $Vnet(VNET.US), $SharonAI(SHAZ.US) fell even harder, generally between -10% and -14%, with the entire AI hardware and data center chain being sold off together.

It's the same logic as the semiconductor wave—a collective pullback after AI optimism pushed valuations higher, with the entire chain from foundry, PCB, server OEM to IDC colocation all declining. $Vnet(VNET.US) was compounded by profit-taking from the previous data center hype, while small-cap AI infrastructure stocks like $SharonAI(SHAZ.US), with higher beta, fell even more sharply. Where the bottom of this correction lies still depends on whether the growth rate of AI capital expenditure will actually slow down.
