In today's pre-market session, US equity index futures came under pressure, with all three major index futures falling by about 0.5%. As a high-beta segment of the AI networking supply chain, optical communications was more significantly impacted by the overall drop in market risk appetite. From a deeper perspective, rising US Treasury yields and crude oil prices, along with the September FOMC meeting minutes signaling a potential rate hike before year-end, have raised new doubts in the market over the scale of the AI investment craze.
