The stock is in a strong bullish alignment (정배열) — price sits well above all three key moving averages (MA5/20/60), and the MACD histogram of +2,378 signals expanding upward momentum. However, the RSI of 91.46 is deep in extreme overbought territory, a level rarely seen and historically associated with near-term consolidation or pullback risk. With price approaching the 52-week high of ₩112,300, short-term profit-taking pressure is material.

🎯 Investment Opinion
Rating: NEUTRAL
Iljin Electric is a fundamentally sound company riding one of the most powerful structural trends in global markets — AI-driven power infrastructure demand. The FY2025 results confirm a genuine business acceleration, and its vertically integrated model from transformers to high-voltage cables provides a real competitive edge.
That said, after a +13.89% single-day surge and an RSI of 91.46, the stock is in extreme overbought territory. Chasing at current levels carries meaningful near-term reversal risk. The valuation at PER ~50x already prices in continued strong earnings growth, leaving limited margin of safety.
- Target Price (1st): ₩125,000 (~+13.7% upside from ₩109,900)
- Stop-Loss / Re-entry Level: ₩94,000 (near MA5 support)
- Strategy: Wait for a pullback toward the ₩94,000–₩96,000 range before initiating or adding positions. Scale in gradually. Monitor FY2026 Q1 earnings for confirmation of continued momentum.
