Ideas
Long Korean memory stocks on AI upcycle
Memory suppliers are gaining pricing power as AI server demand absorbs supply, forcing even Apple to accept higher memory costs. AI capex from hyperscalers continues, so memory upcycle remains intact. Recommend maintaining memory positions and buying on dips rather than chasing. Korean memory stocks SK Hynix and Samsung Electronics are direct beneficiaries.
Avoid Apple, rising memory costs hurt margins
Apple is becoming a price taker as memory costs surge, eroding margins. It has low AI server exposure and high consumer product dependence, making it vulnerable to rising component costs. Cautious on Apple as a cost absorber.
Watch Corning, brilliant tech but expensive now
Corning is a unique AI optical play with dominant glass technology and a platform shift. Optical earnings surged 93% YoY, driven by AI data center fiber demand. The long-term EPS CAGR could reach 30%+ with the 2030 bull case EPS $9.49. However, the current price already reflects the 2030 scenario, making it expensive. Better to wait for a correction to accumulate.
Watch Ciena for AI data center connectivity
Ciena is a top-tier optical networking equipment maker benefiting from AI data center interconnect (DCI). Revenue from hyperscalers and cloud providers is growing fast. Margins have improved to ~20% OM. However, high market expectations caused a sell-off even on good earnings. So the structural growth story is intact, but the stock is for monitoring and buying on pullbacks, watching hyperscaler capex trends.
Buy KOSPI panic after circuit breaker
Historical data since 2000 shows that when the KOSPI circuit breaker triggers (8%+ intraday drop), the next day almost always rebounds, and buying at the panic yields high-probability short-term profits. This is a tactical overlay to buy panic, e.g., via leveraged ETFs like KODEX Leverage.
Buy VM, HBM etch equipment monopoly
VM is the only domestic etch equipment maker with unique plasma etch technology critical for HBM manufacturing. It has exclusivity with SK Hynix, strong earnings (OP margin jumped to 34%), and a high CANSLIM score. The company is in a structural growth phase driven by advanced logic and HBM capex. Strong buy candidate.
Long PSK Holdings, HBM cleaning leader
PSK Holdings is the global leader in dry strip and cleaning equipment, essential for HBM TSV processes. It has high operating margins (30%+) and an unassailable competitive moat from immediate AS service. Strong orders from global fabs and AI memory expansion provide long-term growth. A high-conviction semiconductor equipment play.
Watch Hanall Biopharma, blockbuster autoimmune drug
Hanall Biopharma's FcRn inhibitor IMVT-1402 (licensed to Immunovant) showed excellent Phase 2 data in rheumatoid arthritis, outperforming Humira and Rinvoq in treatment-resistant patients. It has blockbuster potential, with consensus peak sales of ~$5.1B. However, the Korean biotech sector is out of favor due to flow into AI, so it requires patience; fundamentally strong but near-term momentum weak.
Buy Lotte Shopping, rebound pattern confirmed
Quantitative pattern screening: stocks that declined for two consecutive weeks with decreasing negative rates, holding the 5-week moving average, and showing foreign buying, have a high probability of rebounding. Lotte Shopping fits this pattern: -8% two weeks ago, -2.9% last week, keeping its 52-week line, with foreign inflows.
Long Dalba Global, accumulation breakout play
Algorithmic screening also identifies Dalba Global. It has risen slowly, 10% each of the last two weeks, forming a cup-with-handle pattern on weekly chart, with strong foreign buying. The controlled ascent suggests institutional accumulation and a breakout potential.
