Unglamorous physical plumbing — and every AI server rack is full of it.
Sorted by one-month move. “Vs target” compares the current price with the mean analyst price target — a figure from analysts, not from us.
| Company | Price · todayThe latest closing price, and how far it moved from the previous close in dollars and percent. | 1 MonthPrice change since the last close on or before the same date one month ago — a calendar month, not 21 trading days. | 1 YearPrice change since the last close on or before the same date one year ago. | Vs targetHow far the price sits below the average of analysts’ published 12-month price targets. Negative means the price has already risen past that average.Analysts’ figures, not ours. Not a forecast we make or endorse. |

Every rack is full of physical connections — power delivery, high-speed cable assemblies, backplane connectors. Unglamorous, but present in enormous quantity and increasingly demanding as data rates rise.
The appeal is breadth rather than drama: these suppliers sell into many end markets, so AI is additive rather than existential. It also means their results dilute AI exposure with slower-growing businesses.
What moves it: server build rates, connector content per rack, and design wins on new platforms.
The Weekly Pulse covers Connectors & Cables alongside every other sector — one email, Sunday, free.
At high frequencies a connector behaves less like a wire and more like a component that can distort the signal. Maintaining integrity requires tighter tolerances and better materials.
The dollar value of a supplier's parts inside a single rack. Denser AI systems need more connections, so content per rack can rise even when the number of racks does not.
Generally no. Most sell across industrial, automotive and communications markets, so AI is one contributor to results rather than the whole story.
