Very Important Photonics Update

Summary
The article argues that a recent Goldman Sachs insight on four photonics subsegments (Optical Cables, Connectors, Devices, InP Substrates) is a critical signal for investors, especially given that many related stocks have fallen ~50% from highs. The author frames this as a potential opportunity but does not provide specific actionable trades, instead directing readers to a previous report on oversupply concerns and a social media link for the Goldman graphic.
  • The author previously published a report on oversupply concerns in the photonics industry covering multiple layers, impacted companies, and timelines.
  • Goldman Sachs provided new insight that the author considers one of the most important signals in a long time, but the actual data table is not reproduced due to copyright.
  • The insight covers four areas: Optical Cables, Optical Connectors, Optical Devices, and InP Substrates.
  • Many stocks in these photonics subsegments are down approximately 50% from their highs, prompting the author to emphasize understanding the current state as key to identifying opportunities.
