SKHX Holds Above $1,300 After SK Hynix's PER Eclipses Samsung for the First Time

The PER Crossover Korea Watched For

On Wednesday SK Hynix's 2026 forward PER reached 6.79x, edging past Samsung Electronics' 6.77x for the first time on record. The 0.02-point lead is symbolically larger than it sounds. Three months ago Samsung carried a 2.80-point PER premium over SK Hynix — 8.08x against 5.28x — and the gap was conventional wisdom about which company deserved the multiple.

The one-month return profile explains the flip cleanly: SK Hynix +78.68%, Samsung +35.44%. By the cash close on May 13, Samsung's market cap stood at 1,660.34 trillion won against SK Hynix's 1,408.30 trillion won, a 252 trillion-won spread that has been narrowing every print. The framing from a Seoul desk quoted in the same piece — *'the disappearance of Samsung's stock premium means the valuation re-rating of SK Hynix is complete'* — is the kind of line that gets pinned above a trading desk for a quarter.

The macro backdrop did its part. KOSPI closed Wednesday at a record 7,844, with Samsung and SK Hynix together accounting for over 42% of the index. When the country's two largest stocks are also its two best memory franchises, an HBM-led rally and a valuation rerate stop being separate trades.

Why the Perp Is Holding, Not Fading

The previous SKHX mover caught the breakout: a fresh $1,340 perp ATH as Seoul stamped a record ₩1,976,000 close. Twelve hours later the screen looks different but tells the same story. The perp is at $1,332 — eight dollars off the high — with the 23-hour print at +5.86% because the measurement window now straddles the cooler back half of the move. The relevant fact is what *did not* happen: no give-back into the $1,280s, no overnight unwind of the offshore long book, no sign that Wednesday's record close was a blow-off.

Part of that is structural pull from new product wrappers. Leverage Shares has filed with the SEC for a *'2X Long Memory Daily ETF'* tracking the Roundhill Memory ETF (DRAM), whose top holdings are SK Hynix (25.95%), Samsung (20.27%) and Micron (6.41%). REX Shares is separately pursuing a *'T-Rex 2X Long SK Hynix Daily Target ETF'* directly on the ADR. Neither is live, but both signal that US-side demand for leveraged memory exposure has reached the point where issuers are stacking products on the same name — and the SKHX perp is the cleanest 10x version of that trade trading right now.

What the Bankroll Offers Mean

The cleanest read on supply tightness this week is not the analyst targets — it is the customer behavior. The Seoul Economic Daily reported that Microsoft, Google and Amazon are offering to directly fund SK Hynix's production lines and EUV equipment to secure forward HBM allocation, including financing individual ASML High-NA tools that run roughly $400 million apiece. One proposal specifically targets the first phase of the Yongin cluster, which is not even scheduled for completion until end-2027.

The striking detail is that SK Hynix is *resisting*. The company's stance, per the same reporting, is that taking the money would lock it into discounted long-term pricing in exchange for capacity it can already finance internally, and with zero spare capacity through the foreseeable future there is no reason to give that pricing power away. That is the bull case in one sentence: the supplier is turning down hyperscaler capex because the alternative is keeping HBM prices wherever it wants them. The perp holding $1,330 after a multi-day rip is what that posture looks like when the offshore book finally believes it.
