Credo Technology Group Holding Ltd (CRDO) experienced a significant pre-market plunge of 5.68% on Wednesday, as the stock moved sharply lower during the early trading session.

The decline appears to be part of a broader downturn affecting optical communication concept stocks, which generally fell in pre-market trading according to market reports. Other companies in the sector including POET, LUMN, and GLW also saw declines during the same session.

This movement coincides with extended declines in chip and storage shares across the semiconductor sector, suggesting broader industry weakness that has impacted various technology stocks including those in the optical communication space.
