Korea Pre-Market Morning Briefing: Export & Order Momentum Focus amid Macro Volatility

### 1. Global Macro Environment and Pre-Market Direction: Overnight global financial markets closed under macro volatility pressures, with the KRW/USD exchange rate at 1,353.7 and the US 10-year Treasury yield at 5.11%. WTI crude oil recorded $92.85 per barrel while the Fed net liquidity stood at $5,770.0 billion. Scanning the total chart data of the KRX market reveals a clear common thesis governing capital flows. Breakout leaders concentrate in machinery and general industrial manufacturing, steel and industrial metals, and finance/securities sectors, attracting capital due to export/FX benefits and order backlog surges. Technically, these leading stocks formed an upward breakout pattern with an average 1-month return of +3.2% and trading volume expansion averaging 1.4 times the 20-day average. Conversely, breakdown candidate groups in construction, machinery, and health supplements shared vulnerabilities of valuation discounting from prolonged high interest rates and subdued demand, recording an average 1-month return of +0.8% and breaking key support levels. ### 2. Core Momentum Stocks Aligned with the Common Thesis: LS Eco Energy (229640.KS) belongs to the machinery and industrial manufacturing sector, posting a +32.2% surge from its 1-month lows and breaking above resistance. Based on the current price of 64,000 KRW, the upper resistance is set at 67,800 KRW and the lower support at 59,600 KRW. Samsung Electronics (005930.KS) serves as a large-cap semiconductor foundry leader, maintaining a steady upward trend of +7.3% over the past month. At a current price of 285,500 KRW, its upper resistance is 288,000 KRW and lower support is 189,200 KRW, backed by 6.0 trillion KRW in trading value. SK Hynix (000660.KS) trades at 1,862,000 KRW in the semiconductor/AI memory sector with a 1-month return of +7.6%. Upper resistance is identified at 1,935,000 KRW and lower support at 1,246,000 KRW. ### 3. Downside Volatility and Restricted Purchase Targets: Nuon (123840.KQ) in the health supplements and biotech sector exhibits a range-bound consolidation with a 1-month return of +3.9%. At a current price of 1,750 KRW with resistance at 2,325 KRW and support at 1,355 KRW, a conservative stance is maintained against breakdown risks. Dongshin Construction (025950.KQ) in the construction infrastructure sector declined 6.4% from recent highs. At a current price of 9,880 KRW, resistance stands at 13,840 KRW and support at 8,170 KRW, requiring risk management amid slowing forward demand. BQ AI (148780.KQ) in the software sector trades at 3,755 KRW with low trading value, placing it in the restricted purchase category between resistance of 6,420 KRW and support of 1,850 KRW. ### 4. Portfolio Operations and Risk Guidelines: Morning entry strategies should focus on split-lot accumulation for stocks exhibiting volume expansion exceeding 1.4 times the 20-day average upon breaking upper resistance. Chasing rallies is prohibited, and positions must be systematically reduced upon breaking lower support. New entries into small-caps and select construction/biotech issues sharing downside breakdown characteristics are strictly restricted. Maintain adequate cash proportions within the overall portfolio to manage macroeconomic volatility.
