Why is Celestica stock rallying today?

Celestica's stock is experiencing a significant rally today, with shares climbing 5.4% to reach CA$335.87. This surge is primarily driven by the company's upbeat November 10 earnings call, where management projected Q4 2026 revenue between $6.275 billion and $6.575 billion and affirmed its adjusted EPS range of $3.37 to $3.57.

The positive earnings guidance, combined with numerous bullish analyses published today, has helped to counteract a prolonged post-peak slide that had driven Celestica's shares down to a 52-week low of CA$276.06. This recovery follows a strong Q3 2026 earnings beat in which the company reported revenue of $5.83 billion, up 83% year-over-year, and adjusted EPS of $3.30, both surpassing the company's own guidance.

The bullish market sentiment was further bolstered by recent share acquisitions from several institutional investors, including Fulcrum Asset Management and Pictet Asset Management, as well as an upgrade from Zacks Research. Despite this positive news, the stock still trades at a significant discount to its 52-week high, suggesting that there is still room for further recovery if AI demand trends remain robust.

The broader market environment has also played a supportive role, with tech-led indices like the S&P 500 and NASDAQ both advancing, which tends to benefit high-beta stocks like Celestica.
