LATEST SECTOR RESEARCH

Why Has Edge AI Lagged the AI Rally-and What Could Make It Lead the Next Semiconductor Cycle? >

Edge AI is spreading across devices, but adoption has not produced a uniform earnings cycle. This analysis tests the revenue, margin, cash-flow and market-breadth signals that could turn technological progress into semiconductor leadership.

AI Memory Test: Can Bit Growth Defend Earnings When Prices Fall? >

AI is increasing memory demand, but the next valuation test arrives when prices fall and new supply ramps. This analysis revisits the Samsung–SK hynix thesis through Micron’s latest results, historical cycles and the price–bit revenue matrix.

The Next AI Semiconductor Cycle: Is Edge AI Moving From Adoption to Earnings? >

AI-capable phones and PCs are spreading rapidly, but adoption has not yet produced a broad replacement or earnings cycle. GMS examines whether persistent AI agents, hybrid architecture and higher semiconductor content could become the missing catalyst.

South Korea's Defense Advantage Is Real. Are K-Defense Stocks Already Pricing It In? >

South Korea built its defense industry for a threat that never disappeared. Global rearmament is now turning that capacity into an export advantage—but after a powerful rerating, K-defense stocks must prove that orders, localization and technology can translate into durable cash flow.

South Korea’s Shipbuilding Renaissance: From LNG Carriers to the New Battle for Sea Power >

Korea’s shipbuilding revival is moving beyond a cyclical recovery as LNG carriers, naval demand and U.S.–China maritime competition reshape the industry.

South Korea’s Battery Turnaround Has Begun — Can Technology Outrun China’s Overcapacity? >

Korea’s battery recovery is emerging through ESS demand and improving utilization. This research asks whether technology and trusted supply chains can overcome China’s persistent overcapacity.
