Coherent (COHR) Surges 9.16%: What’s Fueling This Semiconductor Giant’s Intraday Rally?

Summary
• Coherent (COHR) surges 9.16% to $152.285, hitting an intraday high of $153.23
• Sector leader Lumentum (LITE) jumps 13.4%, signaling strong momentum in semiconductors
• Options chain shows aggressive bullish positioning with 20 contracts trading at high leverage ratios
• Analysts highlight strategic partnerships and AI-driven demand as potential catalysts

Coherent’s intraday rally has captured market attention, with the stock surging nearly 10% in a single session. This sharp move coincides with broader semiconductor sector strength, led by Lumentum’s 13.4% surge. The stock’s technicals and options activity suggest a mix of short-term volatility and long-term optimism, driven by AI infrastructure demand and strategic business decisions. Traders are now scrutinizing key levels and options strategies to capitalize on this momentum.

Strategic Business Restructuring and Analyst Optimism Ignite COHR’s Rally
Coherent’s 9.16% intraday surge is directly tied to its recent announcement to sell its aerospace and defense business to Advent for $400 million, a move that has reinvigorated investor sentiment. This strategic divestiture allows COHR to focus on high-growth areas like AI and data center infrastructure, aligning with broader industry trends. Analysts at KGI Securities and Rosenblatt have reaffirmed 'Outperform' ratings, citing the company’s ability to streamline operations and capitalize on AI-driven demand. Additionally, COHR’s partnership with Apple on VCSEL technology and its recent earnings beat have reinforced confidence in its long-term trajectory.

Semiconductor Sector Gains Momentum as AI Demand Surges
The semiconductor sector is experiencing a renaissance, driven by AI infrastructure spending and global supply chain adjustments. Lumentum (LITE) leads the pack with a 13.4% intraday gain, reflecting strong demand for laser and optical components in data centers. COHR’s rally mirrors this trend, as both companies benefit from the same macroeconomic tailwinds. However, COHR’s strategic focus on AI and its recent business restructuring differentiate it from peers like ASML and TSMC, which are more exposed to traditional manufacturing cycles.

Options and ETFs to Capitalize on COHR’s Volatility and Sector Strength
• 200-day MA: $92.33 (well below current price), indicating a long-term bullish trend
• RSI: 53.93 (neutral, suggesting potential for further upside)
• MACD: 4.88 (bullish divergence from signal line at 7.10)
• Bollinger Bands: Upper at $163.68, Middle at $141.85, Lower at $120.02 (price near upper band, signaling overbought conditions)

COHR’s technicals and options activity suggest a continuation of its rally, with key resistance at $163.68 and support at $141.85. The stock’s short-term bearish trend clashes with its long-term bullish setup, creating a volatile trading environment. Investors should monitor the 200-day MA as a critical support level and consider leveraged ETFs if available. Given the absence of a leveraged ETF, options remain the primary vehicle for exposure.

Backtest Coherent Stock Performance
Key findings• Sample size: 13 occasions in which COHR.N closed ≥ 9 % higher than the previous session (Jan-2022 → 24-Nov-2025). • Short-term follow-through is weak. The median path turns negative almost immediately and stays below the benchmark for most of the 30-day window. • Worst stretch: day 3–5 after the surge (average –4 % to –5 % vs. +0.5 % for benchmark; statistically significant at the 5 % level). • By day 30 the average event return is +3 %, still lagging the benchmark’s +4 %, and significance tests show no reliable out-performance. → Historically, “+9 % up-days” in COHR have not been good tactical entry points; a short cooling-off period (≈ one trading week) would have reduced drawdown risk.Auto-selected parameters (for your reference)1.
