Celestica (CLS) rebound

Buy CLS into earnings with a thesis that AI hardware/engineering demand stays strong and margins keep rising. The article highlights 53% revenue growth, improving gross/operating margins, and pricing power, plus big-client capex (Google $80B). Technicals are washed out (bear market, broke $324 support), so a beat-and-raise can trigger a fast mean-reversion rally if guidance confirms momentum. Key trigger: guidance that supports the $4.39B revenue / $2.31 EPS expectations and keeps margins expanding.

Key Risk: Earnings beat is followed by weak guidance or margin compression, proving the recent demand/margin strength was temporary and the valuation (forward P/E ~32) can’t be justified.

Celestica (CLS) downside protection

Sell CLS if earnings fail to re-accelerate growth or if management guides conservatively. The stock already broke the $324 neckline and is set for a bearish 50/100 EMA crossover; that’s a setup for continued de-rating. If results don’t clearly beat expectations or guidance disappoints, the market likely targets the next technical downside zone (below the morning star low at $282).

Key Risk: Management delivers strong guidance and margin durability, invalidating the technical breakdown and forcing a re-rating higher.

  • Celestica stock has plunged into a bear market and erased all gains made earlier this year.
  • The company will publish its financial results next week.
  • Its results will need to be so strong to justify the valuation.

Celestica stock has moved into a bear market, mirroring the performance of other artificial intelligence (AI) companies. CLS dropped to $307 in New York, down by over 35% from its highest level this year. This retreat will be put to the test when the company publishes its financial results next week.

Celestica stock in focus ahead of earnings

Celestica, a top Canadian technology company, has slumped in the past few weeks and erased the gains it made earlier this year. It is now trading at the same level it was trading at when the markets opened in January. 

Celestica has become one of the top AI proxies in Canada, thanks to its large partnerships with companies like Alphabet, Meta Platforms, Amazon, and Cisco. Its top ten clients, who include large multi-billion-dollar companies, account for about 10% of its total revenue.

These clients use Celestica’s services, which include hardware design and engineering, electronics manufacturing and systems assembly, supply chain management, and testing and quality assurance.

These services have come in heavy demand this year as companies have boosted their artificial intelligence investments. Big tech companies are also using its services as they design their own chips.

Its most recent results demonstrated this growth. Its revenue jumped by 53% to $4.05 billion, near the upper side of its guided range. Its gross and profit margins also continued rising, helped by its pricing power. Gross margin rose to 10.8%, while its earnings from operations soared to $272 million.

Analysts are upbeat as its earnings loom

The next important catalyst for the Celestica stock price will be its earnings, which will come out next week. These results are expected to show that its business continued doing well as its top clients boost their spending. Google recently said that it planned to spend $80 billion this year.

Analysts tracking the company are largely optimistic ahead of its earnings report. The average estimate is that its revenue will come in at $4.39 billion, up by 51% YoY. For a company that was started 30 years ago, this growth is phenomenal and is a sign that it continues to evolve.

Its earnings per share is expected to come in at $2.31, higher than the $1.39 it made in the same period last year. Celestica has a long track record of doing better than estimates. In its last earnings report, the EPS was better than estimates by 8 cents. 

A stronger-than-expected earnings report and guidance will be bullish for the company as its stock remains under pressure. It will also help it to justify the hefty valuation, with the forward price-to-earnings ratio of 32 being higher than its historical average.

The daily chart shows that the CLS stock has plunged in the past few weeks. It has dropped from a high of $472 in June to the current $307. 

The stock recently dropped below the key support level of $324, the neckline of the head-and-shoulders pattern. Also, the 50-day and 100-day Exponential Moving Averages (EMA) are about to have a bearish crossover.

The stock has recently formed a morning star candlestick pattern, a potential bullish reversal signal. However, unless it breaks above the key resistance at $324 and then clears the psychological $350 level, it is likely to remain under pressure. Conversely, a move below the morning star's low at $282 would invalidate the bullish setup and signal further downside.
