TradingKey - Nasdaq officially announced on May 8 that, Lumentum (LITE.US) will be officially added to the Nasdaq 100 Index before the market opens on May 18, replacing the real estate data company whose stock price has halved this year, CoStar (CSGP.US) .

Since 2026, the optical component manufacturer's stock price has soared 145%, with its market capitalization swelling to the $70 billion mark.

Index inclusion itself does not change business fundamentals, but joining the Nasdaq 100 Index will force tracking funds to buy Lumentum shares. However, for this new optical communications giant with a supply-demand gap exceeding 30% and a P/E ratio approaching 150x, when will the stock price return to the $1,000 mark?

Mandatory passive inflows from tracker funds

Lumentum's inclusion in the index is rooted in a distinct industrial backdrop. As a premier global supplier of optical and photonic components, the company is a major beneficiary of the surging demand for 400G/800G high-speed optical modules fueled by AI computing requirements. Its product suite spans optical communication modules, lasers, and 3D sensing, commanding a significant share of the high-speed optical interconnect market for AI data centers.

Optical communication is now regarded as a pivotal technology for addressing AI computing bottlenecks, making Lumentum one of the most closely watched stocks in this space.

Following its addition to the S&P 500 in March, Lumentum’s entry into two major indices within a three-month span underscores the market's continued conviction in its growth narrative. Index inclusion is expected to drive mandatory buying from passive funds, thereby increasing institutional ownership.

Growth Engine: Revenue Surge and Strong Pricing Power

Lumentum's explosive earnings performance is staggering. Previously, in the third fiscal quarter, net revenue reached $808.4 million, up 90.1% year-over-year, setting a record high; Non-GAAP gross margin jumped to 47.9%, up 1,270 basis points year-over-year; Non-GAAP earnings per share were $2.37, far exceeding the market expectation of $2.27.

The high growth was driven by surging demand for high-speed interconnect components in AI data centers. Specifically, component business revenue reached $533.3 million, up 77% year-over-year, with 200G EML laser chip shipments hitting a record high and narrow-linewidth lasers growing sequentially for nine consecutive quarters, with year-over-year growth exceeding 120%.

Furthermore, Nvidia (NVDA.US) 's $2 billion strategic investment optimized the company's capital structure and provided financial backing for subsequent capacity expansion.

Management's guidance for the next quarter is even more aggressive, with revenue of $960 million to $1.01 billion (up approximately 85% year-over-year) and Non-GAAP EPS of $2.85 to $3.05, both far exceeding market expectations, continuing the momentum of sustained margin enhancement.

Meanwhile, as the supply-demand gap continues to widen, Lumentum, as a 'pick-and-shovel' provider, possesses strong pricing power.

Management stated during the earnings call that key components such as EML and pump lasers are effectively sold out for the foreseeable future, with the supply-demand gap widening from 25%-30% in the previous quarter to over 30%, and 200G EML revenue more than doubling sequentially.

The extreme supply-side tightness has given Lumentum unprecedented pricing power. Morgan Stanley analysts noted that the company's leading position in EML and pump lasers allows it to continuously raise prices and expand profitability against a backdrop of extreme supply constraints.

The $1,000 share price bottleneck: Where do the divergences lie?

As of May 8, Lumentum closed at $903.80, with shares skyrocketing approximately 145% year-to-date and its price-to-earnings (TTM) ratio sitting at about 159x. A return to the $1,000 mark would represent a further gain of roughly 11% from the $902 level, but the crucial factor is the ongoing tug-of-war between bulls and bears over a valuation that is already at historic highs.

The bullish catalyst for challenging the $1,000 threshold may not lie in the valuation itself, but rather in the rigid window for passive fund position-building. Index inclusion after May 18 will drive a large influx of passive capital, providing substantial support for the stock price in the short term.

Meanwhile, judging by the frequent upward revisions of price targets by institutions, the market generally believes that the current valuation has not yet peaked. The core market debate centers on how much of the current 150x P/E pricing represents an advance discounting of earnings performance over the next two years.

For medium- to long-term investors, the short-term consolidation window following the index inclusion on May 18 may provide a more suitable entry opportunity. For short-term traders, the focus of current price action is not whether the ceiling for the AI optical communications sector is high enough, but rather the market's short-term absorption capacity at a 150x valuation.
