On September 28, YOFC fell over 16%, extending its recent downward trend. The decline was driven by a wave of foreign institutional sell-offs combined with mounting investor concerns over fiber optic capacity expansion.

On the institutional front, BlackRock reduced its long position in YOFC H-shares from 6.49% to 5.97% on September 22 through the release of share security interests in an off-market transaction involving 2.18 million shares. Meanwhile, Harvest International Capital Management sold down its stake significantly from 6.4% to 4.87% via on-exchange transactions on the same date, offloading approximately 6.46 million shares. These concentrated disposals intensified selling pressure on the stock.

At the industry level, investor anxiety over new fiber capacity announcements by peers and new entrants potentially disrupting the supply-demand balance continued to weigh on sentiment. Although UBS reiterated a Buy rating with an elevated target price of HKD 330, arguing that overcapacity risks are limited given equipment supply bottlenecks and lengthy customer qualification cycles, short-term market sentiment remained subdued.
