YOFC

YOFC slid 10.46% to HK$86.05 after a low-open, dip-and-recover session: it fell as much as 16.5% to HK$80.25 in the morning, rebounded to HK$88.90 by 10:49 BJ, then softened again in the afternoon. The trigger was a global AI-hardware selloff — the SOX index plunged 12% overnight and AI-regulation worries built after the US midterm sweep, spilling into Asia-Pacific, where the Hang Seng opened 392 points lower, ChiNext opened almost 5% down and the stock gapped 13% lower. Fundamentals contrast sharply with the tape: Q3 2026 revenue reached HK$10.90bn, up 156.27% YoY, with net profit of HK$3.75bn, up 1871.12%, a 34.38% net margin and a PE of just 9.45x. The shares remain up 64.22% year-to-date yet sit 71.79% below the 52-week high of HK$305 and well under the MA20 of HK$117.51. Though turnover of HK$3.66bn and a 10.25% turnover rate showed heavy distribution, the decline narrowed into the close.

Fears that a US halt on data-center expansion will curb AI infrastructure demand hit Hong Kong optical-communication names, and YOFC closed at HK$96.10, down 12.5% from HK$109.80, after a spike-and-fade session that touched HK$105.50 at 10:19 BJ and HK$91.60 at 13:58 BJ on HK$5.47 billion turnover. UBS cut its target price 45% to HK$180, while Haitong International cut 39.2% to HK$144. Fundamentals remain strong: Q3 2026 revenue reached HK$10.9 billion, up 156.3% year on year, with net profit of HK$3.75 billion, up 1871%, and a 34.4% net margin, implying PE of 10.55x. Yet the shares sit 68.5% below the June 22 52-week high of HK$305 and under MA20 of HK$121.6 and MA60 of HK$151.6, with YTD gains narrowed to 83.4%, though Q3 net margin of 34.4% eased from Q2's 39.7%.

AI hardware stocks rebounded and the Philadelphia Semiconductor Index gained nearly 3% overnight, helping YOFC reverse early weakness: after touching HK$105.3 in the morning session, the shares fell to HK$98.9, then rallied in the afternoon to HK$110.5 and closed at HK$109.8, about 11% above the morning low and only 0.6% below the intraday high. The session thus formed a pullback-then-recovery pattern, with the close near the top of the day’s range. The move also drew support from strong Q3 results: revenue reached HK$10.899 billion, up 156.27% year on year; net profit was HK$3.7475 billion, up 1,871.12%; EPS was HK$4.5453, up 1,707.41%; and net margin was 34.38%. Haitong International cut its target price from HK$236.8 to HK$144, maintained its Accumulate rating and raised profit forecasts. The optical-communication sector has retraced significantly since Q3 while public funds and insurance capital added to leading names, providing a backdrop for the rebound. Though the stock had a 6% single-day pullback during the sector correction and the target-price revision was downward, volatility has not dissipated.

YOFC fell 6.25% to HK$100.5 in a spike-and-fade session: after opening at HK$104.4 and touching HK$107.0 in the morning on follow-through from the prior day's rally in A- and H-share optical names, the stock slid to HK$99.1 in the afternoon as Marvell's formal announcement of its Lumentum acquisition raised supply-chain reshuffle concerns and Hong Kong AI concept stocks extended losses, before a small close-of-day recovery. Southbound flows have been net sellers of Hong Kong stocks for 14 straight sessions, while HK$983 million of YOFC positions, or 2.42%, changed hands, adding pressure. Fundamentals contrast sharply with the tape: Q3 revenue reached HK$10.9 billion, up 156% year on year, net profit HK$3.75 billion, up 1,871%, and net margin 34.38%, leaving the shares at just 11.04x PE. The stock is still up 91.79% year to date but sits 67.05% below its 52-week high of HK$305 set on 22 June and well under its MA20 of HK$129.28 and MA60 of HK$152.32; Nomura cut its target price to HK$167. Still, Q3 net margin narrowed from 39.74% in Q2, so the durability of earnings momentum bears watching.

YOFC (6869.HK) gapped up and extended gains through the Hong Kong morning, reaching and holding HK$109.20, up 5.3% from the prior close of HK$103.70 on HK$454 million turnover, as US optical-sector strength lifted Hong Kong optical-communication names broadly and AI hardware stocks rebounded together after Anthropic disclosed large computing-power purchase commitments, with the Hang Seng Index opening 42 points higher. Q2 2026 results underpin the move: revenue of HK$7.06 billion (+84.61% YoY), net profit of HK$2.81 billion (+1677.77%), net margin at 39.74% and quarterly EPS of HK$3.412. Still, at HK$109.20 the shares sit below the MA20 of HK$143.38 and MA60 of HK$153.33, 64.2% under the 52-week high of HK$305 set on 22 June, though up 108.4% year to date, while southbound funds were net sellers of YOFC on the day, with the stock at 22.81x PE.
