SK Hynix Leads AI Stock Selloff After Record US Listing Fails to Stop 35% Slide

• SK Hynix shares plunged as much as 15%, leading the rout in the KOSPI index and dragging Samsung stock lower as the broader stock market crash intensified, putting heavy pressure on AI stocks across Asia
• SK Hynix has now fallen more than 35% from its June peak as investors booked profits after its US listing, while concerns over weaker HBM demand and slower HBM4 production weighed on leading AI stocks
• Despite the recent selloff, analysts continue to maintain a bullish long-term outlook on SK Hynix, although lower earnings forecasts and ongoing volatility in the KOSPI index suggest near-term risks remain elevated

Asian markets are bleeding extensively as South Korea’s KOSPI recorded a steep fall of 9%. In addition to this, the selloff was led by SK Hynix, which has fallen as much as 15%, with Samsung stocks taking a hit in the middle, falling by nearly 11%. SK Hynix, touted as one of the leading AI stocks, has crashed primarily as traders accumulated their profits, pushing SK Hynix shares to plummet even further.

Why Is SK Hynix Stock Falling Today?

The KOSPI index had fallen by nearly 9% Monday morning as stock markets around the world took a brutal hit. The KOSPI index wiped off billions in the process, with SK Hynix and Samsung stocks nose-diving ahead in the process. These AI stocks have suffered primarily due to investors collecting their profits post Sk Hynix’s US listing. The bullish sentiment ended up gnawing at the SK Hynix stock narrative, pushing Samsung stocks to take an equal hit. 

SK Hynix shares are now down 35% since their peak in June 2026. 

“The KOSPI fell -9% on Monday, triggering a trading halt for the 7th time this year, out of 13 total since 2000. The selloff was led by SK Hynix, which fell as much as -15%, its largest daily drop on record, while Samsung dropped nearly -11%. This comes just 1 trading day after SK Hynix’s US listing, the largest ever first-time US share sale by a foreign company at $26.5 billion. SK Hynix shares are now down more than -35% from their June all-time high.”

The stock market crash worsened globally as the US-Iran conflict is taking a new route again. That being said, the global indexes are once again bracing for impact, with predictions of gold and precious metals rallying taking the central stage again.

Future Share Forecast Of The Korean AI Giant Is Now In Jeopardy

The heavy profit accumulation that led to the fall of the stock will eventually level the playing field. Once through, the SK Hynix shares are bound to regain their lost valuation. Korea Investment Securities is still bullish on the SK Hynix share, issuing a buy signal for the asset. However, the entity has also decreased the profit forecast for SK Hynix stock by nearly 9 to 11%.

The firm also cited how fleeting HBM demand over time with supply ramps may end up jeopardizing the SK Hynix share price in the near future. 

“Korea Investment Securities cut 2026-27 operating profit forecasts for SK Hynix shares by 9-11%. The July 13 note still maintains a buy rating with a 3.8 million KRW target but highlights a 2Q reality check: weaker HBM sales mix, slower ASP growth, and HBM4 ramp delays. A consensus miss looks likely. In Korea, analysts rarely issue outright sell calls. This quiet estimate reduction is their version of waving a caution flag. Memory chip euphoria has limits. HBM demand is strong but not infinite, and supply ramps bring margin pressure. SK Hynix rode the AI wave hard, but cracks are showing.”
