SK Hynix Outpaces Peers Before Tuesday's Print, but the Month's Damage Runs Deep

SK hynix gained 4.4% on Friday to close at KRW 1,277,000, its best single-day move in weeks. That recovery matters because the stock had shed 30.6% over the prior month, a slide driven by the Samsung-TSMC-Nvidia supply chain report documented in last week's ORTEX note. Against that backdrop, Friday's bounce is striking, but it still leaves the stock well below the levels where most institutional models were anchored.

The borrow market confirms short sellers are not pressing their advantage into the print. Availability is extraordinarily loose, running above 9,000%, meaning roughly 97 million shares are available to borrow against a tiny fraction actually on loan. Cost to borrow has dropped 16% over the past week to 0.26%, near the lowest level in the 30-day history. The ORTEX short score has been drifting lower for two weeks, from 25.9 on October 9 to 25.5 now, placing it in the 95th percentile of the universe for low short pressure. That is not the positioning of a stock where the short-selling community is adding new conviction ahead of results.

The valuation case has become sharper as the price has fallen. The trailing price-to-earnings multiple is now 2.7x, the price-to-book 1.4x, and EV/EBITDA 2.1x, all compressing materially over the past 30 days as the share price dropped while earnings estimates held. The EV/EBIT factor ranks in the 98th percentile of the ORTEX universe, and the earnings yield factor ranks in the 96th percentile. Those numbers reflect a stock priced for very bad news. Whether the news on Tuesday is bad enough to justify that pricing is what the market disagreed about through October.

The earnings history adds context. At the July 29 print, the stock fell 14.7% on the day but recovered 7.6% over the following five sessions. The print before that, in late April, produced a 3.9% day-one drop followed by a 27.8% five-day decline. Two prints, two very different post-earnings trajectories, which argues against reading the initial reaction as the whole story.

The week's performance relative to peers is notable. SK Hynix gained 0.4% over the past week. Its closest correlated peers all fell: MU slipped 0.1%, while TSEC-listed names fell between 1.3% and 7.5%. Something caused SK Hynix to decouple to the upside just before reporting. Whether Friday's 4.4% session was short covering, pre-earnings positioning, or a fresh read on the competitive landscape is what Tuesday's numbers will begin to answer.
