1. Taiwan Dual-Listings Monitor: TSMC Premium Compresses; ASE and UMC Flip to Discount

By Vincent Fernando, CFA, Zero One

  • TSMC ADR premium compressed to +14.5%, nearly 6pts below its 2-year median of        +20.4%, signalling a potential trade in the ADR relative to the local. 
  • ASE and UMC both trade at discounts to local shares (-3.0% and -2.0%), with ASE ADR   short interest dropping 20% even as Taiwan short interest climbs.
  • ChipMOS ADR short interest surged 141% to 37,452 shares, though on thin volume.

2. TechChain Insights Q&A: Legacy DRAM Squeeze — How AI’s Capacity Grab Is Reshaping the Memory Market

By Vincent Fernando, CFA, Zero One

  • Legacy DRAM has shifted to a truly sellers’ market, with buyers unable to  secure full order quantities as lead times extend to months.
  • HBM and DDR5 capacity reallocation by Samsung, SK Hynix, and Micron is squeezing legacy supply, creating openings for Taiwanese specialty producers.
  • IoT demand is accelerating, while large buyers actively dual-source amid geopolitical uncertainty and Chinese capacity expansion.

3. TSMC: Arm’s Foundry Exclusivity Reinforces Advanced Node Dominance & Margins Stronger for Longer

By Vincent Fernando, CFA, Zero One

  • Arm’s AGI CPU deepens TSMC’s advanced-node monopoly; every leading chip architecture now manufactures exclusively at TSMC.
  • We forecast TSMC gross margins 200-400bps above consensus through FY2029E, implying 10-12% EPS upside not priced in.
  • Accumulate on weakness: ~20x FY2026E earnings after a 14% pullback; we rate TSMC a Structural Long.

4. Fujitsu (6702 JP): Targeting AI Inference at 1.4nm

By Scott Foster, LightStream Research

  • With its stock price down 30% from its January peak, Fujitsu deserves another look.
  • Management is setting long-term target with development of a Neural Processing Unit for AI inferencing to be produced by Rapidus at 1.4-nm.
  • Sales and profits are now threatened by the economic disruption caused by the war on Iran, but restructuring and demand for AI-driven corporate service solutions should support long-term margin expansion.
