MAPS Portfolio Note: Apple just said it better than we could — the memory shortage is far from over

When Apple says something has become “unavoidable,” the world pays attention. This week, CEO Tim Cook confirmed to the Wall Street Journal that the company will raise prices on its devices to offset surging memory chip costs.

ASML’s shares reached a new all-time high of USD 1,903 last week, surpassing the USD 1,750 target we set in April.

Every dollar spent on AI chips has to flow through this company

USD 750 billion. That is how much five of the largest hyperscalers are projected to spend on AI infrastructure in 2026 alone, roughly 73% higher than last year. Much of that capital ultimately flows downstream into chips and fabs, and ASML remains the sole supplier of the most critical machines in that ecosystem. This week, its CEO confirmed that the company’s next-generation lithography systems are already producing real chips. The bull case has not weakened. It has strengthened.

MAPS Portfolio Note: TSMC and SK Hynix just made the case for Asia semiconductors

We recently increased our Asia ex-Japan exposure from neutral to overweight and initiated a position in the Global X Asia Semiconductor ETF. The latest 1Q26 earnings from two of the ETF’s largest constituents — TSMC and SK Hynix — have validated that decision.

ASML powers ahead as customer upgrades reinforce 20% upside potential

ASML delivered a solid set of results for 1Q26 but the real highlight was the upgrade to its full-year outlook — a clear signal that the current AI-driven capex cycle is running harder and for longer than previously anticipated. We see an upside potential of 20% for ASML.
