⏰ What’s Happened To Korea’s Market?

South Korea saw a historic sell‑off today( 28 July 2026). The KOSPI plunged -10.84% , its worst single day since March 2026.

Leading the crash: SK Hynix down 14.7% and Samsung Electronics down 14.4%, both posting record one‑day falls.

This sharp drop is driven by three big worries:

Doubts over whether heavy AI spending can keep up, geopolitical tensions and fast‑rising competition from China.

The fall also remind or signals a much more cautious outlook for the whole global memory sector.

Before rushing to “buy the dip,” remember: weakness in these giants may be a warning for memory stocks everywhere.

Key watchpoint: Both companies report earnings this week, their updates will decide if sentiment stabilises or worsens. Trade carefully and do your homework first.

$SK Hynix(SKHY.US)

KOSPI is down almost 10% as of now. Samsung Electronics and SK Hynix are “bleeding” as much as 9.5% and 10.9%, respectively.

Institutional and retail investors are dumping AI-related bets amid mounting concerns over financing risks tied to AI infrastructure spending and intensifying competition from China.

The real threat is coming from China. CXMT can bring new capacity online far faster, roughly about a year faster than SK Hynix typically takes 2–3 years to build and ramp advanced fabs.

How can you compete against that speed? I cannot imagine😔

Today is Tuesday. Fed meeting coming Thursday early morning. Watch out and respect Fed😌.

$Micron Tech(MU.US)

Micron Technology is no longer just another cyclical memory maker—it has become one of the biggest beneficiaries of the AI infrastructure boom. Fiscal 2026 results reached record levels, driven by surging HBM (High Bandwidth Memory) and data-centre DRAM demand, with management guiding another strong quarter as HBM4 enters volume shipments.

Against its Korean rivals, SK hynix remains the HBM leader with over 50% market share, while Samsung Electronics is regaining momentum after HBM qualification delays. Micron ranks third but is rapidly narrowing the technology gap through superior execution and long-term AI customer contracts. Industry capacity is effectively sold out through 2026, allowing all three suppliers to enjoy exceptional pricing power and gross margins.

The key risk is not an immediate flood of Chinese competition. Despite Beijing’s support for domestic memory champions, advanced HBM manufacturing remains years behind the leading trio due to process complexity, packaging know-how and customer qualification. The bigger medium-term risk is oversupply from aggressive capacity expansion after 2027.

For option traders, the trend remains bullish but increasingly volatile. Selling cash-secured puts on major pullbacks or using bull put spreads offers a better risk-reward than chasing rallies, while long-term investors should accumulate on corrections rather than expect today’s extraordinary pricing cycle to persist indefinitely.

Goldman Sachs: Samsung Electronics

I agree that the recent pullback looks more like a reset in expectations than the end of the AI investment cycle. Markets tend to overreact whenever sentiment shifts, especially after such a strong rally. As long as AI infrastructure spending and enterprise adoption continue to expand, quality companies with strong execution should still deliver attractive long-term returns.

For me, volatility is part of investing rather than something to fear. Instead of trying to predict every short-term move, I'd rather stay focused on fundamentals, maintain disciplined position sizing, and use sharp pullbacks to gradually build positions in companies I have conviction in. Over time, patience usually matters more than perfect timing.
