MA5	₩47,300	Bullish (price above)
MA20	₩41,968	Bullish (price above)
MA60	₩42,756	Bullish (price above)
RSI (14)	80.74	Overbought ⚠

• 1st Support: ₩47,300 (MA5)
• 2nd Support: ₩44,000 (stop-loss zone)

While the MACD histogram of +1,146 indicates powerful buying momentum, the RSI of 80.74 has entered overbought territory (above 70). This dual signal suggests the underlying bullish trend remains intact, but short-term profit-taking pressure may intensify near the 52-week high resistance.

💰 Fundamental Analysis

Jeju Semiconductor reported explosive earnings growth in FY2025, confirming its position as a key beneficiary of on-device AI and LPDDR memory demand expansion.

Metric	FY2024	FY2025	YoY Change
Revenue	₩162.3B	₩302.2B	+86.2%
Operating Profit	₩9.6B	₩35.9B	+274.5%
Net Income	₩19.4B	₩39.5B	+103.5%
Total Assets	₩225.4B	₩336.0B	+49.1%
Total Equity	₩184.2B	₩227.1B	+23.3%
Total Debt	₩41.2B	₩108.9B	+164.3%
Debt Ratio	22.4%	47.9%	Expanded but still low
ROE	~10.5%	~17.4%	Improving

Revenue nearly doubled to ₩302.2B, while operating profit surged over 2.7x to ₩35.9B — a remarkable margin expansion driven by operating leverage in the LPDDR memory business. Although total debt rose from ₩41.2B to ₩108.9B (partly linked to equity issuances in early 2026), the debt ratio of 47.9% remains well below sector averages, and liquidity is solid with ₩280.4B in current assets. ROE improvement to 17.4% demonstrates effective capital deployment. The company's LPDDR memory chip portfolio is well-positioned within the structural AI demand cycle.

🎯 Investment Opinion

Rating: Neutral | Confidence: Medium

The medium-to-long-term directional thesis for Jeju Semiconductor points upward: the FY2025 earnings surprise and on-device AI beneficiary narrative are credible and supported by hard financial data. However, following today's +18.16% surge — with RSI above 80 and the stock touching a new 52-week high — near-term overbought signals are clear. Chasing the current price carries meaningful short-term risk.

Recommended Strategy: Wait for a pullback to the MA5 support zone (~₩47,000) or the February breakout base (~₩44,000) before initiating or adding positions. Use a phased (dollar-cost averaging) entry approach.

Level	Price
Mid-term Target Price	₩62,000 (~+14.8% upside from current)
Re-entry Zone (MA5)	₩47,000 – ₩47,300
Stop-Loss	₩44,000 (Feb breakout base)

For international investors, note that USD/KRW currency fluctuations add an additional layer of return variability. Monitor the ongoing share dilution risk from recent equity issuances and watch for any follow-on capital raises.
