Information technology shed more than 3% over five days, with Amkor Technology down 15%, Credo Technology down 11%, and Meta down almost 7%. Here's what actually happened and why it's not the same story everywhere.

Let's put a number on just how rough this stretch has been for tech, because the individual stories we've covered this week — Marvell's pre-earnings de-risking, the semiconductor selloff, Meta's ongoing struggles — add up to something bigger than the sum of their parts. Information technology as a sector shed more than 3% over a recent five-trading-day stretch. That's a genuinely bad week for a sector that's driven most of this year's index gains.
The names that took the worst of it
Amkor Technology and Credo Technology were the biggest laggards, falling nearly 15% and 11% respectively over those same five days. Meta Platforms was down almost 7% over the same stretch, adding weight to the sector's overall decline. Three very different companies, three very different reasons for the pain — which is really the point I want to make here.

Why lumping these together misses the real story
It's tempting to write "tech had a bad week" and move on, but that framing actually obscures more than it reveals. Amkor and Credo are both semiconductor-supply-chain names, and their declines line up with the broader chip-sector weakness we've documented extensively — rising bond yields hitting high-multiple names hardest, positioning ahead of Nvidia's earnings, and general risk-off sentiment in anything AI-infrastructure-adjacent. Meta's decline is a different animal entirely, tracing back more to the specific AI capex and free-cash-flow concerns that have dogged the stock since its own earnings report weeks ago.
What actually connects them
If there's a genuine common thread, it's this: every one of these three stocks sits somewhere on the AI infrastructure spectrum, whether that's chip packaging, connectivity hardware, or the megacap actually funding the buildout. When bond yields spike the way they did this week, the entire spectrum gets repriced roughly together, even though the underlying reasons for each stock's specific exposure are quite different.
My honest take on how much this matters
A three-percent sector-wide weekly decline isn't catastrophic in isolation — sectors have rough weeks constantly. What makes this one worth flagging is the timing: it's happening right before Nvidia's earnings and the Jackson Hole symposium, two events we've covered as potentially decisive for where sentiment goes next. A weak setup heading into major catalysts tends to amplify whatever direction those catalysts push the market, for better or worse.
What to watch next
Whether Amkor and Credo specifically stabilize once the pre-Nvidia positioning resolves itself one way or another. Whether Meta's decline extends or whether this week's broader tech weakness was simply piling onto an existing story. And honestly, whether next week's Nvidia report becomes the catalyst that reverses this entire five-day slide, or the one that confirms it was the start of something more sustained.

Rough weeks in tech happen. What matters is whether this one turns out to be a shakeout before a bigger move higher, or the opening chapter of something longer. We'll know a lot more by the time Nvidia reports.
