Yangtze Optical Fibre and Cable Joint Stock Limited Company is entering the summer with short sellers quietly walking away from one of Hong Kong's most actively contested fibre names. The question is whether the retreat reflects conviction — or just profit-taking ahead of August results.
Short sellers have been unwinding in a hurry. SI % FF has dropped from a peak of roughly 15.1% in early May to 10.4% today — a fall of nearly a third in six weeks, and a roughly 8% decline over the past week alone. That is not noise. Over the same period the stock gained around 6% on the month and 5% on the week, closing at HKD 239.2 on Friday before a sharp 4.6% pullback on June 5. The direction of travel is clear: shorts built aggressively through late April and into early May, then reversed course as the price climbed.
The borrowing market has loosened considerably alongside that unwind. Cost to borrow has retreated to 3.26% — down from above 5% through most of April, and roughly 24% cheaper than a month ago. Availability has swung even more dramatically: it now runs at around 395% of outstanding short interest, up from the mid-to-high 100s just two weeks ago and a sharp reversal from levels where borrowing shares was genuinely difficult. That kind of loosening is consistent with a large-scale return of borrowed shares to the lending pool. When shorts close, availability floods back. The 52-week low for availability was 0.36% — so today's reading, while elevated, is a reminder of how constrained the borrow market was at the peak. The ORTEX short score has also moved in tandem, easing from 62 to 53.5 over the past two weeks, still in moderate-to-elevated territory but no longer flashing the warning signals it was earlier in May.
Ownership tells a different story from the positioning data. The register is unusually concentrated. WuHan Yangtze Communication Industry Group and China Poly Group together hold roughly 51% of the company — strategic and largely immovable. Below them, the more active institutional players have been shuffling. JPMorgan added over 9 million shares as recently as March, while E Fund Management — a 5% shareholder — sold 4.7 million shares in April after buying back 852,000 in late March. Barclays also reported a sale of 2.97 million shares in April. The net 90-day insider and large-holder activity shows around 14.5 million shares net bought, though that figure is dominated by the December CPE subscription of 25 million shares at HKD 32.26 — a very different price level from today's HKD 239.2. BlackRock added to its position as recently as May 25, a modestly constructive signal from a passive-weighted buyer. Analyst consensus points to a mean price target of HKD 198.45, below the current price. The analyst recommendation differential ranks in the 94th percentile of the ORTEX universe — an unusually wide gap between analyst caution and current market pricing.
Valuation has moved sharply. The trailing P/E now runs at 35.5x, up nearly 5 points over 30 days, while the EV/EBITDA at 55.9x has jumped more than 26 points in the same window. Those are stretched multiples for an optical fibre manufacturer, and the price-to-book at 8.5x reinforces the premium embedded in the current price. Against that, 90-day EPS momentum ranks in the 98th percentile of ORTEX's coverage universe, and the 12-month forward EPS growth estimate scores in the 81st percentile — the market is clearly pricing in strong earnings delivery rather than mean-reversion. The earnings release on May 22 showed only a mild 0.7% one-day move, with a 5.6% recovery over the following week, suggesting the results were broadly in line. The prior event on April 29, however, saw a 12% single-day decline. The next scheduled print is August 26.
Among the correlated peers tracked by ORTEX, the dispersion this week has been notable. One SEHK-listed peer (1720) posted a one-week gain exceeding 77%. Several mainland-listed names — including tickers on the SHSE and SZSE — gained 8–25% on the week. Against that backdrop, YOFC's more modest 5% weekly gain suggests the stock may have lagged the broader optical and communications infrastructure rally, though its steeper one-day pullback on June 5 also stands out. With the next earnings event eight weeks away and valuation multiples at elevated levels following a strong run, the August 26 announcement will be the next concrete test of whether the market's premium pricing is justified.
