SK Hynix stock jumped 13 percent on its Nasdaq debut, topping Alibaba's US listing

[BretHart88]

SK Hynix shares climbed roughly 13 to 14 percent on their first day of Nasdaq trading after the company raised about 26.5 billion dollars in its IPO, a figure that reportedly tops even Alibaba's prior US listing

The debut caps off a stock that had already climbed 174 percent over the prior six months and 634 percent over the past year on the Korea Exchange before this US listing even happened

SK Hynix captured 56.4 percent of the global HBM market according to its own SEC filing, and the underlying demand story is straightforward, AI chips like Nvidia's GPUs rely on high bandwidth memory sitting right next to the processor to avoid becoming slow and inefficient

Interestingly memory stocks broadly fell into a bear market territory just around the same time this debut happened, so SK Hynix popping while the broader sector wobbles is a notable divergence worth watching

This listing also gives US retail and institutional investors an easier direct path into the AI memory supercycle story without having to deal with Korea Exchange access, which analysts think could draw a meaningful new wave of capital into the stock

A 13 percent pop on debut after already gaining 634 percent over the past year is genuinely eye watering, that is not a normal IPO trajectory by any historical standard

The broader memory sector falling into a bear market right as this one company pops is a weird divergence, feels like investors are betting specifically on SK Hynix's HBM dominance rather than memory chips in general

[Chris27]

Topping Alibaba's US listing size is a notable milestone for a Korean company, that puts SK Hynix in some very exclusive company for foreign listings

56.4 percent market share in HBM is basically a near monopoly position, that pricing power alone probably justifies a lot of the investor enthusiasm here

[SharpLantern]

I would be nervous buying into a stock that already ran up 634 percent in a year, that kind of momentum usually means a lot of the good news is already priced in

[Olivia78]

This feels like the market's clearest vote yet that HBM specifically, not memory chips broadly, is the actual scarce resource in the AI buildout right now

[Zach72]

Giving US investors direct access without Korea Exchange friction is a bigger deal than people realize, that alone probably explains part of the day one pop from pent up demand

[Kieron]

Genuinely curious how this performs a year from now once some of the new manufacturing capacity everyone is building actually comes online and eases the current shortage

[FrostBear]

Nvidia's entire roadmap is basically hostage to how much HBM SK Hynix, Samsung, and Micron can collectively produce, that dependency is wild when you really sit with it
