Lumentum falls 18.6% after quarterly results because of its earnings release

What happened

Lumentum (LITE) fell 18.6% on November 2, 2026, because of its quarterly earnings released that day. The stock closed at $684.40 after it opened 4.5% below the previous close, and trading volume was 2.9 times its 20-day average. The move came amid broader weakness: the S&P 500 fell 0.5% and the technology sector median fell 1.5% on the day, but the stock’s decline was sharply larger than those indexes.

How big was the move

The session’s decline measured 3.0 times a typical daily move for this stock, an outsized reaction to the results. Over the last five sessions the stock fell 16.3%, while the S&P 500 over five sessions fell 1.8%. The stock’s market value stood at $76.15 billion at the close. Its market sensitivity — a beta of 2.12 — means the stock tends to move more than the market, amplifying company-specific news.

The technical picture

Technically the stock sat well below several shorter-term averages. It was 24.1% below its 20-day moving average and 25.5% below its 50-day moving average. The stock was 14.8% below its 200-day moving average, while the 50-day average remained above the 200-day average, a sign of an established uptrend despite recent weakness.

Price action has been volatile. The stock fell 36.9% over one month and fell 19.4% over three months, yet it rose 242.0% over one year, leaving it 40.1% below the 52-week high. The Relative Strength Index (14 days) was 35, inside a neutral range between 30 and 70. Volatility registered 98% annualized over 60 days, a level higher than 90% of its own readings over five years.

Fundamentals and valuation

For the four quarters through September 26, 2026, Lumentum reported revenue of $3.74 billion, which grew 103.2% from a year earlier. Gross margin stood at 45.9% versus 30.6% a year earlier, and operating margin was 23.0% compared with 5.7% a year earlier. Diluted earnings per share for the period were $-89.47, and earnings per share growth from a year earlier fell 6104.7%.

Return on invested capital was 7.9%, and the company’s share count over one year increased by 29.9%. The stock traded at 31.4 times expected earnings on a price to forward earnings basis. Those figures show rapid top-line growth and margin improvement alongside sharply negative per-share metrics driven in part by a higher share count.

Revenue doubled versus the prior year, and margins expanded, but the diluted EPS loss and a nearly 30% rise in shares outstanding weighed on per-share returns. Investors must weigh strong growth and improving margins against substantial EPS distortion and a stretched valuation.

Earnings and analyst expectations

Lumentum’s last report on November 2, 2026, showed earnings per share of $4.57 against $4.22 expected, 8.3% above estimates. The company has beaten estimates in 14 consecutive quarters and its average surprise over the last four reports was 10.0% above estimates. Typical two-day reactions after recent reports fell 1.1%, but this session produced a much larger decline because of the results.

Analysts remained generally bullish on the shares. The consensus price target was $1,116.00, 63.1% above the closing price, based on 25 analysts. Seventy-two percent of those analysts rate the stock Buy or Strong Buy and the consensus rating was Buy. The company’s next report was listed for November 3, 2026.

The gap between analyst targets and the market price reflects a split view. Analysts are modeling continued strong growth and assign a high valuation, while the market pressed the stock sharply lower on the headline reaction to the report and the surrounding news flow.
