SK Hynix shareholders had plenty to digest this week, and not much of it was comfortable. The memory maker’s stock ended Friday down 3.0%, dragged lower by a broad retreat in Nvidia shares and by media-reported anxiety over artificial intelligence spending and memory-chip demand. The selling rippled through other memory producers and major Nvidia suppliers, while uncertainty surrounding Nvidia’s leadership added a further layer of caution toward Korean technology names as investors weighed possible knock-on effects across the AI ecosystem.
Yet the day-to-day noise in the share price is only part of the story. A separate thread — the financing behind a chunk of those shares — has been tightening its grip on the stock’s trading behavior.
Leverage Concentrates in Two Names
As of Thursday, outstanding securities loans for SK Hynix stood at 3.3311 trillion Won. Combined with Samsung Electronics, such loans reached 6.9669 trillion Won, meaning the two stocks accounted for 27.2% of the corresponding margin credit across KOSPI and KOSDAQ. Within the KOSPI alone, the pair represented 36.5% of outstanding securities loans — down from 33.6% of the broader market on August 12, but still a hefty tilt toward two names.
Broadcaster SBS reported that this concentration is amplifying recent market swings. For SK Hynix, the issue is not the operating business but how part of the shareholder base is financed — and how quickly borrowed positions could turn into forced selling if volatility persists.
Regulators Take Aim at the Collateral Rule
Authorities have responded on two fronts. The collateral requirement of 140% has been temporarily suspended since November 9, a measure running through January 31, 2027. At the same time, regulators are pressing for per-stock and per-borrower credit limits. The suspended collateral rule does nothing to disperse the concentration in SK Hynix and Samsung Electronics, so the question of how those positions behave in further swings remains live for investors.
Friday’s 3.0% decline underscores the tricky backdrop, though it offers no way to tell how much of the move came from leveraged selling.
Should investors sell immediately? Or is it worth buying SK Hynix?
A Halved Target, an Unchanged Rating
The week’s other headline came from Morgan Stanley, which on Tuesday cut its price target on SK Hynix to 1.6 million Won from 2.6 million Won — a reduction of roughly 38% — while keeping its “Overweight” rating. The brokerage pointed to risks to memory-business profitability after 2028. The sharp trim, in other words, did not come with a downgrade of the investment recommendation.
Certification Wins and a Foundry Push
Against that cautious backdrop, the company kept rolling out operational news. On Wednesday, SK Hynix said its LPDDR5X DRAM received certification for industrial functional safety under IEC 61508 SIL 3, and that its cybersecurity management development process was certified under ISO/SAE 21434. The company framed both as support for its push into physical AI applications, emphasizing safeguards against system failures and cyber threats.
At foundry subsidiary SK keyfoundry, the focus is on power semiconductors for AI servers. Media reports on Thursday said the company plans to expand production at its Cheongju plant, where Vishay Intertechnology is ramping MOSFET manufacturing, with shipments having begun in October.
For investors, the takeaway is less about a fresh earnings forecast than about reading the tape correctly. Alongside operating expectations, the financing structure behind SK Hynix shares deserves attention — a concrete reason not to treat every price swing as a verdict on the company itself.
