description: "$Ciena(CIEN.US) has risen nearly five points, while $CIG(06166.HK) on the Hong Kong stock side has fallen nearly six points. Both are on the optical communication track. $Ciena(CIEN.US) is following the demand for optical modules from AI data centers, which is a solid logic. The Hong Kong stock is more dragged down by the overall sentiment of the Hong Kong hardware sector. The demand for optical interconnect from AI computing power is certain, but the way this demand is priced in the Hong Kong and US markets is completely divergent. Is this stratification a dislocation caused by short-term capital flows, or does the Hong Kong optical communication sector inherently lack the support of an independent narrative? It looks more like the latter; the Hong Kong side hasn't yet developed its own story."

- **美股大心脏 · 2026-07-10T19:10:20.000Z**: cien is really grinding. Missed the rally, two months of flying knives, it's killing me. Falls every day, even when it rises, it falls back down.
