Market Review: KOSPI’s ‘Hot and Cold’ Finale—Samsung’s Legendary Run Defies Macro Turbulence

On Friday, February 13, 2026, the South Korean stock market experienced extreme intraday volatility as investors balanced ‘holiday cash-outs’ with ‘FOMO-driven’ accumulation. The KOSPI rose +0.68% to close at 5,559.98, having touched a record-shattering 5,583.74 earlier in the session. While the KOSDAQ fell -1.21% to 1,112.36 due to profit-taking in secondary batteries, the main board remained resilient. The session was defined by Samsung Electronics’ most powerful weekly performance since 2008 and a legislative breakthrough for the domestic nuclear sector.

1. The Samsung Super-Cycle: From ’17th Floor’ to the 290K Target

The semiconductor sector successfully weathered global "AI Fatigue" concerns as domestic hardware dominance reached a fever pitch.

• Historic Weekly Surge: Samsung Electronics (005930) rose for its 6th consecutive day, marking a 15% weekly gain—the largest since the 2008 financial crisis.
• Target Price Skyrockets: Nomura Securities aggressively raised its target price for Samsung to 290,000 KRW and SK Hynix to 1.56 million KRW, citing the absolute scarcity of HBM4 supply for hyperscalers.
• HBM4 Readiness: SK Hynix (000660) has officially moved into the mass-production phase for the world’s first HBM4, aiming to reclaim the "Semiconductor Crown".
• Key Tickers: Samsung Electronics (005930), SK Hynix (000660), Micro-Contact Solution (098910).

2. Nuclear Breakthrough: The SMR Special Law Passed

A major legislative win provided a fresh growth engine for Korea’s heavy industry and energy sectors.

• Policy Catalyst: The ‘SMR (Small Modular Reactor) Special Law’ successfully passed the plenary session of the National Assembly, marking a turning point for energy security.
• Global Expansion: This law, combined with Romania’s final investment approval for domestic SMR tech, has opened the door for Korean firms to become the sole gateway for U.S. SMR projects.
• Key Tickers: OrbiTech (046120), Han-KEPCO (011760), KEPCO E&C (052690).

3. Financial Super-cycle: Brokerage and the ‘Value-up’ Boom

The brokerage sector saw double-digit gains as daily trading volumes stabilized at record highs, fueling a "Value-up" frenzy.

• Brokerage Explosion: SK Securities (001510), Mirae Asset Securities, and NH Investment surged as they were re-rated for their low PBR and record commission revenue.
• STO Market: The selection of the "NXT Consortium" as the preliminary operator for the STO (Security Token Offering) exchange further energized the fintech and brokerage space.

4. Notable Trend: Anthropic’s $380B Valuation and SKT

The global AI race moved into a high-stakes fundraising phase, directly impacting domestic telecom giants.

• Claude Momentum: Anthropic (maker of Claude AI) successfully raised $30 billion at a $380 billion valuation, far exceeding previous estimates.
• The SKT Link: SK Telecom (017670) surged +10.8% as its early-stage investment in Anthropic saw a massive valuation re-rating, positioning SKT as a core AI holding company.

5. Macro Outlook: Silver Margin Calls and CPI Jitters

Despite the record highs, several macro "Red Flags" caused a late-session shake.

• The Silver Crash: A 10% drop in silver prices and a dip in Bitcoin triggered margin calls for global funds, forcing them to offload KOSPI blue-chips to cover collateral.
• CPI Jitters: Investors are cautious ahead of tonight’s US CPI release. A "bad combination" of falling consumption, strong employment, and sticky inflation could trigger a tactical pullback post-holiday.

Institutional Conviction: Top 5 High-Trend Tickers

Institutions and ‘Financial Investment’ desks aggressively accumulated these leaders before the holiday break:

1. Samsung Electronics (005930): The primary engine of the market, currently in a "Price Discovery" phase toward 200,000 KRW.
2. SK Securities (001510): Leading the brokerage rally (+18.9%) on Value-up and STO exchange expectations.
3. SK Telecom (017670): Surging on the Anthropic Series G valuation success.
4. OrbiTech (046120): The top pick for the SMR Special Law breakthrough.
5. Aton (158430): Gaining as the primary "Security Partner" for the emerging STO and digital asset ecosystem.

Investor Strategy: The KOSPI has successfully cleared the 5,500 hurdle, but the ADR remains at a historically high level, signaling that a period of tactical digestion is imminent. While the HBM4 Super-cycle and SMR Special Law provide an unshakeable long-term floor, we recommend using the post-holiday week to selectively rebalance into "Oversold Mid-caps" that have yet to participate in the large-cap rally. Maintain an aggressive long bias on SK Telecom and Nuclear leaders, as they are currently sidestepping the volatile tech-service jitters.
