Lumentum Plunges 5% as AI Hype Fades and Shorts Pile On

Summary
• LITE slumps to $322.69 intraday, a 5.06% drop from $351.42
• Robeco cuts stake by 37.6%, insiders sell $7.3M in Q4
• Analysts split between 'Moderate Buy' and 'Hold' amid 235x P/E concerns
• Earnings report looms on Feb 3, 2026, with $1.30–$1.50 EPS guidance

Lumentum Holdings (LITE) is in freefall as short sellers capitalize on waning AI-driven optimism and valuation skepticism. The stock’s 5.06% intraday plunge to $322.69—its lowest since 2023—reflects a perfect storm of insider selling, elevated short interest, and a stretched P/E ratio of 235.85. With Q2 2026 earnings due in mid-February, the market is bracing for a volatile reaction to a stock that’s surged 296% since 2024 but now faces a critical inflection point.

Short Sellers and Analyst Divergence Fuel Selloff
LITE’s collapse stems from a confluence of factors: institutional investors like Robeco Institutional Asset Management B.V. slashing their stake by 37.6%, insiders offloading $7.3 million in shares, and a 235x P/E ratio that dwarfs the S&P 500’s 23x. While analysts like Needham & Co. upgraded LITE to 'Buy' with a $290 target, others—Raymond James and Susquehanna—cut their price targets, citing overvaluation. The stock’s 5.06% drop also reflects a broader selloff in AI-adjacent optical tech, as investors question whether LITE’s 58.4% YoY revenue growth can justify its stratospheric valuation.

Communication Equipment Sector Mixed as LITE Dives
The Communication Equipment sector, led by Cisco Systems (CSCO) down 0.318%, is broadly mixed as LITE’s 5% plunge underperforms. While AI-driven optical tech remains in vogue, LITE’s 235x P/E—versus CSCO’s 14x—highlights its premium pricing. Sector news points to a shift toward Wi-Fi 8 and 6 GHz spectrum reallocation, but LITE’s short-term pain underscores the sector’s volatility as investors balance AI optimism with valuation realism.

Backtest Lumentum Holdings Stock Performance
The backtest of Lite's performance after a -5% intraday plunge from 2022 to now shows favorable results. The 3-Day win rate is 50.72%, the 10-Day win rate is 50.31%, and the 30-Day win rate is 51.55%. The maximum return during the backtest was 10.63% over 30 days, indicating that Lite has a tendency to recover from significant intraday declines over various short-to-medium-term horizons.

LITE Faces Crucial Test as Earnings Loom
LITE’s 5% selloff signals a pivotal moment for a stock that’s surged 296% since 2024 but now faces a valuation wall. With short-term support at $324.28 and resistance at $371.68, the path forward hinges on its Feb 3 earnings report and whether the $1.30–$1.50 EPS guidance justifies its 235x P/E. Investors should monitor Cisco Systems (CSCO), the sector leader down 0.318%, for broader market cues. For LITE, the key takeaway: Watch for $324.28 breakdown or a rebound above $330 to dictate next steps.
