Kshitija Bhandaru

Celestica (TSX:CLS) has certainly made its way onto investors’ watchlists, thanks in part to a recent move that might seem puzzling in the absence of a major headline event. Sometimes, stock movements happen quietly, prompting investors to pause and wonder if there is a story beneath the surface. Perhaps a new narrative is forming, or it is just the market re-evaluating what the company is worth. Either way, the action around Celestica is capturing attention right now.

Looking at the numbers, it’s clear that momentum has been building throughout the year. Over the past year, Celestica has delivered a strong total return, far outpacing the broader market. Notably, the stock has surged more than fourfold over the past year, capped off by a dramatic rise in recent months. Short-term performance has also been eye-catching, with a substantial jump in the past three months and even more pronounced gains in just the past week.

After such a rapid climb, is Celestica undervalued, or is the market already pricing in every last bit of growth? Let’s dig into the details and see what the numbers really say.

Most Popular Narrative: 8% Overvalued

According to the most widely followed narrative, Celestica is currently trading above what analysts consider its fair value, based on forward-looking financial projections and recent business momentum.

Widespread digital transformation initiatives and technology transitions (AI/ML compute, next-gen racks) across hyperscalers and digital native customers are expanding Celestica's design pipeline and deepening customer engagements. This increases revenue visibility and improves per-customer revenue potential.

It revolves around accelerating demand, new tech investments, and a transformation of the company’s revenue mix. The real surprise? The numbers that analysts are betting on to justify this premium.
