With shares posting such rapid gains, the key question is whether Celestica remains undervalued today or if the market has already priced in all of its future growth. This leaves investors pondering if there is still a buying opportunity.

Celestica’s widely followed narrative suggests a fair value that sits just above the last close price, hinting the stock may still hold some upside even after rapid gains. With the company’s outlook now shaped by bullish projections and improved profitability, attention is turning to major catalysts that could drive further revaluation.
