SK Hynix’s Sharp Correction Masks Ambitious Plans: Nasdaq Listing and TSMC Alliance in Focus

Despite a 7.7% stock plunge, SK Hynix is advancing HBM4 production with TSMC, planning a 2026 Nasdaq listing, and commanding 52% of the global high-bandwidth memory market.

The euphoria surrounding SK Hynix hit a speed bump on Friday as the stock tumbled 7.66 percent to 1,819,000 won, wiping out weeks of gains in a single session. The sell-off, triggered by the breakdown of a US-China summit without fresh technology accords, saw institutional investors rotate out of the high-flying chipmaker. Yet the pullback looks more like a pause than a reversal: the shares still trade roughly 56 percent above their 50-day moving average and have surged almost 169 percent since the start of the year.

Beneath the surface volatility, the company is executing a radical strategic overhaul. Management has confirmed plans to list on the Nasdaq during the second half of 2026, a move that would give the memory giant direct access to US capital markets. At the same time, SK Hynix is reconfiguring its next-generation HBM4 architecture by outsourcing the base chip’s production to Taiwan Semiconductor Manufacturing Co (TSMC). The collaboration is designed to fine-tune performance for Nvidia’s upcoming “Rubin” platform, underscoring how memory chips are evolving from commodity components into bespoke building blocks for artificial intelligence infrastructure.

The ramp-up is already under way. Mass production of the new 16-layer HBM4 chips starts later this year, and the company’s capacity is effectively sold out through the rest of 2026. Major cloud operators — Microsoft, Meta, and Google among them — have locked in supply, handing SK Hynix extraordinary pricing power. That dominance shows up in the numbers: the group commands 52 percent of the global high-bandwidth memory market, and its first-quarter operating margin hit 72 percent.

The demand-supply imbalance is feeding into analysts’ spreadsheets. KB Securities recently lifted its KOSPI year-end target to 10,500 points, forecasting a combined operating profit of 630 trillion won this year for SK Hynix and Samsung Electronics. For 2026 alone, the consensus for SK Hynix’s operating profit stands at more than 210 trillion won, with DRAM margins approaching 80 percent, according to market watchers.

A curious dynamic is playing out among foreign investors. Despite pulling a net 80 trillion won out of the KOSPI since November, their market-cap-weighted exposure to SK Hynix has actually climbed from 31 percent to 38 percent of the index — purely because the stock’s price has risen so much faster than their selling. Together, SK Hynix and Samsung now absorb nearly 64 percent of all foreign portfolio holdings in South Korea’s benchmark. Daishin Securities analysts see the recent selling as portfolio rebalancing rather than a loss of faith.

Near-term attention shifts to the ex-dividend date on May 28, when shareholders will receive a quarterly payout of 750 won per share. Longer term, the company is building up a war chest to fund its massive Yongin semiconductor cluster, with management prioritising cash reserves over buybacks. The capital spending will be needed to keep pace with the memory super-cycle — South Korean DRAM export prices surged 35 percent in early May alone, while NAND prices shot up 47 percent.

The stock’s slide on Friday left its relative strength index at just under 69, still in bullish territory but flashing a warning that technical corrections are a recurring risk. For now, the fundamental story remains intact: a company with sold-out fabs, pricing leverage that rivals foundry margins, and a strategic pivot toward the US and Taiwan that could reshape its valuation narrative entirely.
