[Korea Pre-Market Strategy] Capital Concentration in Machinery and Materials amid Global Macro Volatility... Key Support Levels for Opening

### 1. Global Macro Environment and Opening Direction Check Following the close of the New York stock market and the USD/KRW exchange rate finishing at 1,351.9, the US 10-year Treasury yield recorded 5.24%, maintaining macro volatility. Federal Reserve net liquidity stood at $5,759.2B, forming a restricted liquidity environment. Scanning the overall chart data of the domestic stock market today, upward breakout leading stocks concentrated in machinery and general industrial manufacturing (6 stocks, approx. 60%) and steel and industrial metal materials (1 stock, approx. 10%). From a business perspective, a common thesis of capital inflow into companies benefiting from exports, exchange rates, and exploding order backlogs was confirmed. Technically, a signature appeared where prices broke above and settled on the upper resistance line amid a 1-month average return of +9.2% and increased trading volume relative to the 20-day average. Conversely, downward breakdown watch stocks, mainly in construction, civil infrastructure, health functional foods, and bio-health sectors, experienced margin pressure due to prolonged high interest rates, recording an average 1-month downward trend of -0.4%. ### 2. Capital-Concentrated Leading Stocks Meeting Today's Common Thesis LS Eco Energy (229640.KS) belongs to the machinery and general industrial manufacturing sector, trading at 61,900 KRW. It formed a strong upward trend, surging +34.3% from the bottom over the past month and breaking through the upper resistance line. The upper resistance line is 67,800 KRW and the lower support line is 59,300 KRW; phased entry around 59,300 KRW is effective rather than chasing the opening price. SNT Energy (100840.KS) is currently priced at 36,450 KRW, down -1.88% from the previous session. Over the past month, it rose +19.3%, showing a breakout flow accompanied by trading volume relative to the 20-day average. The upper resistance line is set at 40,550 KRW and the lower support line at 35,200 KRW, with a strict stop-loss principle if it breaks below 35,200 KRW. Samsung Electronics (005930.KS) closed up +0.93% at 272,500 KRW, condensing range-bound energy. It maintains stable trading volume relative to the 20-day average between the upper resistance line of 288,000 KRW and the lower support line of 189,200 KRW. ### 3. Downside Volatility Expansion and Restricted Purchase Stocks Dongshin Construction (025950.KQ) belongs to the construction and civil infrastructure sector, trading down -2.10% at 9,770 KRW. Over the past month, it declined -6.3% from the high, increasing upper supply pressure. If it breaks below the lower support line of 8,170 KRW, further expansion of downside volatility must be guarded against. CMG Pharmaceutical (058820.KQ) is in the pharmaceutical and biotech drug development sector, recording 553 KRW. It has shown range-bound consolidation with a 1-month return of -3.0%, but is currently testing support around the 1-month core support line of 526 KRW. Due to lingering concerns over stock consolidation and administrative designation, new purchases are strictly prohibited. ### 4. Portfolio Management Principles and Risk Guidelines for the Day Chasing purchases on stocks lacking volume during the opening price formation process is strictly restricted. Stocks that fail to break the upper resistance line and drop below the 20-day moving average must be reduced in weight immediately. Maintain cash portions within the portfolio above a certain level to thoroughly manage risks against exchange rate and interest rate volatility. In particular, approach companies belonging to downward breakout groups with a sell-on-rally perspective to defend capital losses.
