2026.07.24 SK Hynix(000660) Korea Stock Analysis - Neutral

📌 Company Overview

SK Hynix (KRX: 000660) is one of the world's largest memory semiconductor manufacturers and a core subsidiary of South Korea's SK Group. Headquartered in Icheon, Gyeonggi Province, and led by CEO Kwak Noh-jung, the company designs and produces DRAM and NAND flash memory. In recent years, SK Hynix has emerged as the global leader in High Bandwidth Memory (HBM), the specialized memory that powers AI accelerators, making it a central beneficiary of the ongoing AI infrastructure boom. It is the second-largest listed company on the Korea Exchange (KOSPI) by market capitalization.

📈 Current Stock Price

As of the market close, SK Hynix presented the following snapshot (As of 2026-07-24 16:10 KST, market close):

  • Current Price: ₩1,759,000
  • Daily Change: -₩160,000 (-8.34%) — a sharp single-day plunge
  • Volume: 4,935,571 shares
  • 52-Week High: ₩2,987,000
  • 52-Week Low: ₩245,000

The stock has fallen roughly 41% from its June peak of ₩2,987,000, reflecting a severe correction in Korean semiconductor large-caps.

🔧 Technical Analysis

The technical picture is decisively bearish. The current price of ₩1,759,000 sits below all key moving averages — MA5 (₩1,821,600), MA20 (₩2,144,950), and MA60 (₩2,086,550) — forming a complete bearish alignment (dead cross structure) that confirms a clear downtrend.

  • Moving Averages: Full bearish alignment (price < MA5 < MA60 < MA20), a strong downtrend signal.
  • RSI: 30.2 — entering oversold territory, hinting at potential for a short-term technical rebound.
  • MACD: MACD line (-132,110) is below the signal line (-82,384) with a negative histogram (-49,726), maintaining a sell signal with strong downside momentum.

The key battleground is the psychological support at ₩1,700,000. A successful defense could trigger an oversold bounce, while a breakdown risks further downside toward lower levels.

SK Hynix Daily Chart

💰 Fundamental Analysis

In stark contrast to the weak price action, SK Hynix's fundamentals are exceptionally strong. Driven by surging HBM and AI demand, the company posted record-breaking full-year 2025 results:

MetricFY2024FY2025YoY Change
Revenue₩66.2 tn₩97.1 tn+46.8%
Operating Profit₩23.5 tn₩47.2 tn+101.2%
Net Income₩19.8 tn₩42.9 tn+116.9%
Total Equity₩73.9 tn₩120.7 tn+63.3%

Operating profit more than doubled year-over-year, marking the best performance in the company's history. Financial health is sound, with a debt-to-equity ratio of approximately 46% (total liabilities ₩55.4 tn / total equity ₩120.7 tn), while expanded capital expenditure strengthens the foundation for future growth. That said, valuation is a concern: with PBR exceeding 10x and share-supply pressure from a recent rights offering, some brokerages have set a target price of ₩1,850,000 with a Neutral rating.

📰 Recent News & Disclosures

The news flow on the day was overwhelmingly negative, dominated by a market-wide sell-off:

  • KOSPI plunged 5.7%, giving back the 7,000 level in a single day; sidecars (trading curbs) were triggered in both markets. (Einfomax)
  • SK Hynix dropped 8.34% to ₩1,759,000, leading the decline among semiconductor large-caps alongside Samsung Electronics (-7.59%). (Digital Today)
  • Foreign and institutional investors dumped over ₩5 trillion in net selling, with SK Hynix and Samsung Electronics the top two net-sold names, as profit-taking hit the AI semiconductor rally. (Pinpoint News)
  • Macro risks intensified: escalating Middle East conflict (Houthi Red Sea blockade), high oil prices, and interest-rate anxiety weighed on risk sentiment. (SME Daily)

Key DART Disclosures:

⚖️ Bull vs Bear Factors

🐂 Bull Factors🐻 Bear Factors
Record 2025 earnings; operating profit more than doubled on HBM/AI demandKOSPI sidecar triggered; ₩5 tn foreign/institutional net selling — sharply deteriorating supply/demand
RSI 30.2 oversold — potential short-term rebound and bargain-hunting inflowsMacro risks: Middle East conflict (Red Sea blockade), high oil prices, rate instability
Expanded capex and HBM4 mass production securing mid-to-long-term growth41% drop from peak; downtrend plus share-supply overhang from rights offering

🎯 Investment Opinion

Overall Rating: Neutral (Confidence: Moderate)

SK Hynix combines solid fundamentals — record 2025 earnings driven by HBM and AI — with a strong short-term downtrend marked by full bearish alignment, a MACD sell signal, and compounding macro headwinds. While the oversold RSI leaves room for a technical bounce, heavy supply/demand pressure from the KOSPI sidecar and large-scale foreign selling favors a wait-and-see or phased approach over chasing the price.

  • Target Price: ₩1,850,000
  • Stop-Loss: ₩1,650,000

A defense of the ₩1,700,000 support could set up a rebound, but a breakdown opens the door to further correction — hence a recommended stop-loss at ₩1,650,000. From a mid-to-long-term view, the earnings growth trajectory remains intact, making it reasonable to treat this correction phase as an opportunity for gradual, staggered accumulation.
