ASML monopoly conviction offsets FICO and Apple skepticism

JulienTechInvst is most focused on semiconductor infrastructure, especially ASML’s EUV monopoly, hybrid bonding, Nvidia AI compute demand, and cloud economics. He is bearish on FICO’s moat durability and valuation, mixed on Apple with product skepticism but margin/pricing confidence, and disclosed long exposure to TSM and BESI at portfolio highs. Late-week attention moved toward ASML supply-chain control and 2CRSI short-report risk, while warning that hot bottleneck themes can sell off before revenues peak.

Direction this week

Conviction is concentrated in semiconductor infrastructure, led by ASML’s EUV monopoly and supply-chain control, plus hybrid bonding exposure through BESI and TSM. Bearish pressure is clearest in FICO, where he moved from limited-growth caution to moat erosion, valuation, and regulatory risk. There are no CALL_DIRECTIONAL trade signals, but position disclosures show held exposure to BESI and TSM, while ASML and AAPL are concentrated single-ticker discussion areas.

Grade is our human read-worthiness rating; trader score is a rolling 20-bet hit-rate/alpha composite — different things, often disagreeing. “Since then” is direction-unaware in the table; the summary line above adjusts for which way they leaned.
