📈 Current Stock Price

(As of 2026-07-03, market close; data collected 2026-07-05 KST)

  • Current price: ₩192,600
  • Daily change: -₩34,900 (-15.34%) — a sharp single-day plunge
  • Volume: 3,073,252 shares
  • 52-week high / low: ₩283,000 / ₩26,050

The stock was the single best performer on the KOSDAQ in the first half of 2026, surging roughly +625.6% from about ₩27,700 at the start of the year. The recent 15%+ drop reflects heavy profit-taking after that extraordinary run.

🔧 Technical Analysis

Moving averages remain in a bullish alignment — MA5 (₩207,940) > MA20 (₩203,190) > MA60 (₩162,073) — confirming the powerful medium-term uptrend. However, the current price of ₩192,600 has slipped below both the 5-day and 20-day lines, signalling a short-term correction phase.

  • RSI: 41.8 — neutral zone, neither overbought nor oversold
  • MACD: 5,544.7 vs. signal 6,468.6 (histogram -923.9) — a bearish dead-cross giving a short-term sell signal
  • Trend: sideways/consolidation; key support ₩165,000, resistance ₩230,000

Extreme volatility (the last session's -15.34% move) suggests the stock is searching for direction between the ₩165,000 support and ₩230,000 resistance bands.

Jusung Engineering Daily Chart

💰 Fundamental Analysis

Despite the euphoric share price, the underlying earnings have deteriorated sharply:

Item (₩ bn)FY2024FY2025YoY
Revenue409.4310.7-24.1%
Operating profit97.231.3-67.8%
Operating margin23.7%10.1%-13.6%p
Net income106.835.7-66.6%

On the positive side, the balance sheet is solid: total equity of ₩590.5bn against total liabilities of ₩297.4bn puts the debt-to-equity ratio near 50.4%, indicating healthy financial stability. The concern is valuation: at a market cap of roughly ₩9.3 trillion, the stock trades at an extreme PER of about 260x and PBR of roughly 15.7x on FY2025 earnings — far detached from fundamentals. The current price also exceeds the brokerage consensus target (around ₩120,000) by more than 60%.

#4 semiconductor brand reputation in KoreaMACD dead-cross; price 60%+ above consensus target; macro (U.S.–Iran) risk

🎯 Investment Opinion

Overall rating: Neutral (confidence: moderate). Jusung Engineering owns a compelling growth story as a leading AI-semiconductor front-end equipment supplier, backed by glass-substrate and solar momentum and the strongest share-price performance on the KOSDAQ this year. However, with FY2025 revenue down 24% and operating profit down 68%, the ~260x PER represents a theme-driven premium unsupported by fundamentals. Combined with foreign net selling and a bearish MACD dead-cross, near-term correction risk is elevated.

  • Target price: ₩210,000
  • Stop-loss / key support: ₩165,000

Rather than chasing the rally, a prudent approach is to wait for the ₩165,000 support to hold before considering entry. The long-term growth thesis remains intact, but the current price sits in a speculative premium zone.
