SK Hynix Joins the Nasdaq. But This Nasdaq-100 Semiconductor Stock Could Be an Even Better Buy for the Second Half of 2026.

SK Hynix (SKHY) surges 241.5% YTD after launching a U.S. share sale and listing on Nasdaq (July 10), highlighting a multi-year memory-chip supply squeeze tied to AI demand. The article argues HBM/DRAM and AI NAND are key bottlenecks for AI workloads and positions SK Hynix as a pure-play on memory outpacing supply, while naming ASML as the longer-horizon, higher-quality AI picks-and-shovels due to its EUV/High-NA lithography monopoly. ASML is described as trading at a forward P/E of 49.5 vs 49.2 for Applied Materials and 43.5 for Lam Research, with memory revenue share rising to 51% in Q1 2026 vs 42% in Q1 2025.

Analysis

The real economic rent in this AI memory bottleneck is still upstream, not in the commodity memory names themselves. ASML captures the scarcity premium because every additional HBM/DRAM wafer that matters for AI ultimately pulls through advanced lithography capacity; by contrast, memory producers can enjoy a strong tape now but remain exposed to a sharp multiple reset once supply catches up or pricing inflects lower. AMAT and LRCX should benefit as the capex cycle broadens, but they do not have the same monopoly-like pricing power as ASML in the highest-end node migration.

Near term, the cleaner trade is around flows and index mechanics rather than fundamentals. SKHY’s U.S. listing and probable Nasdaq-100 inclusion can create a few weeks of forced buying, but that is a mechanical demand event, not a durable earnings rerating. Over 1-3 months, the key catalyst is whether memory ASPs and ASML order commentary confirm that this is a multi-quarter shortage or merely a late-cycle squeeze; the first sign of HBM/DRAM normalization would hit the memory basket first.

The contrarian miss is that the market tends to overpay for the bottleneck product and underpay for the toolmaker that benefits from every winner. The risk/reward is therefore better in ASML on weakness than in chasing MU/WDC/SNDK after a strong run, especially with ASML’s valuation already requiring sustained backlog conversion. Falsifiers: a slowdown in order growth, any sign of overbuild in memory capacity, or guidance that AI fab spend is being pushed out beyond the next two quarters.

Key Decisions for Investors

• Buy ASML on pullbacks and hold 6-18 months; the thesis is that the company monetizes the entire AI node-upgrade cycle, while memory names only monetize one scarce input. Falsify on a backlog/order miss or any delay in High-NA adoption.
• Pair trade: long ASML / short MU or WDC into memory-led rallies, targeting 3-6 months. The trade works if memory pricing mean-reverts faster than tool demand; cover if DRAM/HBM pricing re-accelerates or if ASML raises guide materially.
• Tactical event trade: long SKHYV into Nasdaq-100 inclusion mechanics, then trim after the passive-flow window. This is a days-to-weeks trade, not a structural compounder unless earnings convert the scarcity story into sustained free cash flow.
• Use AMAT and LRCX as lower-conviction semicap beta, but prefer ASML for concentrated exposure. If the AI capex wave broadens beyond memory, ASML should outperform on a risk-adjusted basis because of its lithography moat.
