Celestica Plummets 7.8% Amid Sector Turbulence: What's Fueling the Selloff?

Summary
• Celestica (CLS) plunges 7.77% to $282.09, its worst intraday drop since 2023
• Intraday range spans $281.90 to $312.30, signaling sharp volatility
• Sector leader Cisco (CSCO) declines 1.47%, hinting at broader tech sector pressure

Celestica’s dramatic selloff has captured market attention as the stock collapses nearly 8% in a single session. With the Communication Equipment sector under pressure and key technical indicators flashing caution, investors are scrambling to decipher the catalyst behind this sharp reversal. The stock’s 52-week high of $363.40 now feels distant as the 200-day moving average at $202.59 looms as a critical support level.

Earnings Silence and CEO Share Sales Spur Profit-Taking
The absence of near-term earnings catalysts and a recent $10.6 million insider sale by CEO Robert Mionis have triggered profit-taking. With Q4 2025 results not due until January 28 and no material news in the past week, the stock has become a victim of its own momentum. The lack of positive guidance from management, combined with the CEO’s liquidity event, has created a vacuum of confidence. This is compounded by the sector’s broader struggles, as AI infrastructure spending shows early signs of moderation.

Communication Equipment Sector Under Pressure as Cisco Drags
The Communication Equipment sector is broadly weaker, with Cisco Systems (CSCO) down 1.47% as investors rotate out of high-PE tech plays. While Celestica’s 43.08x P/E ratio is elevated compared to sector averages, its recent volatility outpaces peers. The sector’s focus on AI infrastructure is encountering short-term headwinds as hyperscalers delay capex decisions, creating a ripple effect across the supply chain.

Bearish Options Play and ETF Positioning in a Volatile Climate
• 200-day average: $202.59 (far below) • RSI: 58.17 (neutral) • MACD: -2.98 (bearish divergence) • Bollinger Bands: 263.89–346.78 (price near lower band)

The technical picture suggests a continuation of the downtrend, with key support at the 200-day MA and resistance at the 30-day moving average ($303.12). The RSI’s 58.17 reading indicates moderate bearish momentum, while the MACD histogram’s positive value hints at potential short-term stabilization. For leveraged exposure, consider boldETFs tracking the sector if available, though none are specified here.

Backtest Celestica Stock Performance
The backtest of CLS's performance after a -8% intraday plunge from 2022 to now shows favorable results. The 3-Day win rate is 59.82%, the 10-Day win rate is 62.50%, and the 30-Day win rate is 69.87%, indicating a higher probability of positive returns in the short term. The maximum return during the backtest was 24.16%, which occurred on day 59, suggesting that CLS has the potential for significant gains following a sharp decline.

Urgent Action Required as Celestica Tests Key Support Levels
The selloff shows no immediate signs of abating, with the 200-day MA at $202.59 and 52-week low of $58.05 forming a dangerous downward trajectory. Investors should monitor the $280 psychological level and the 200-day MA as critical inflection points. With sector leader Cisco (CSCO) down 1.47%, the risk of a broader tech selloff remains elevated. Aggressive traders may consider shorting CLS20260116P280 if the $280 support breaks, while longs should wait for a confirmed rebound above $303.12 before re-entering.
