Optical Cable is trading 6.00% lower at $15.19, with no company-specific announcement identified to explain the October 8 pre-market decline. - The latest quarterly results were reported on September 9, not overnight. - The decline follows a weak October 7 session and comes amid softer global markets, higher yields, and oil-price concerns. - Supplied pre-market index moves are each under 0.5%, making broad-market pressure context rather than a confirmed direct catalyst.
