Photonics Leaders Being Sold

• Corning (GLW) is down 40% from highs despite a $135 billion market cap and projected sales of $11.1 billion (2027) and $14.6 billion (2028), with institutional investors actively buying during the decline.
• Marvell (MRVL), valued at $240 billion, is expected to grow earnings per share from $1.66 (2025) to $4.60 (2028) as data centers increasingly adopt optical signal conversion technology.
• Both stocks have shown 'outlier inflows' from institutional investors over the past year and are included in MoneyFlows Frontiers indexes for Photonics (GLW) and AI (MRVL).

Photonics Sector Summary

Key Companies and Market Performance

Two major photonics companies face selling pressure despite strong fundamentals:

Corning (GLW)

• Market cap: $135 billion
• Down 40% from recent highs
• Projected sales: $11.1 billion (2027), $14.6 billion (2028)
• Core fiber optics provider for AI data transmission infrastructure

Marvell (MRVL)

• Market cap: $240 billion
• Manufactures semiconductors converting electrical signals to optical signals
• Strong per-share earnings growth (specific figures not disclosed)
• Experiencing institutional buying despite current weakness

Sector Context

Photonics technology enables data transmission at light speed, critical for AI infrastructure as data centers require low-latency solutions. The sector has shifted from electrical to optical data transmission using lasers and fiber optics, driving demand for specialized suppliers.

Market Implications

Despite current selling pressure and months of flat performance, both stocks show:

• Strong institutional buying with "outlier inflows" from major investors
• Solid fundamentals supporting long-term growth
• Attractive valuations following recent declines
• Strategic positioning in AI infrastructure buildout

The article suggests current weakness presents buying opportunities before potential recovery. Institutional investors continue accumulating positions, indicating confidence in the sector's AI-driven growth trajectory. MoneyFlows has included both companies in new "Frontiers" indexes tracking photonics and AI themes.
