Focused on AI photonics and semiconductor supply chains — sourcing asymmetric setups from bottoms-up value-chain research. Tracks CPO & optical modules closely, with ongoing deep-dives on SIVE, AAOI, LITE, POET.
Quick verdict
PSMC is neutral (0 bull · 0 bear)
Named as a supplier of DRAM wafers, with +45% COGS hikes that impact net income less than memory price increases.

- Just in case you're wondering why I'm so bullish on legacy memory... Their hikes seem a lot extreme than $NBIS reported +17-21% GPU rentals today or Taiyo-Murata type MLCC hikes. Price hikes projections expected for H2: - SLC NAND: +120-170% in H2 vs H1 - High-capacity NOR: +90-110% in H2 vs H1 - ~DDR3/DDR4: +50% Q3 - DDR2: +35-40% in Q3 - LPDDR: +20% or more in Q3 - DDR1, older LPDDR and PSRAM: also rising As a consolidated view... Lot of these are stacked off existing hikes H1, (eg. 130-150% for H1 SLC NAND), so you get +406%-575% cumulative throughout 2026. Which impacts blended net income overall more than upstream wafer COGS hikes (eg. +45% DRAM wafers from $PSMC) So I'd expect Q3 earnings for a lot of the legacy memory fabless companies to cook
