Fundamental equity research on the AI value chain: memory and logic semiconductors at the core, with the infrastructure, power, and defense names the same capital cycle pulls into scope. Coverage spans US and Korean listings, including both sides of the same company's dual listing.
Every report publishes a fair-value band, an entry level, sell baselines, and a stated rating, and commits the exit conditions before publication, not after the fact.
Coverage: Semiconductors · AI Infrastructure · Software & Internet · Financial · Aerospace & Defense · Materials · Healthcare
Built to be graded. Each report commits its fair-value band, entry level, and exit conditions at publication. Nothing is revised after the fact, and every report stands alone with its own data as of the publication date.
Fair value is a function of earnings, not price. Valuation runs on through-cycle earnings, replacement cost, and segment-aware sum-of-the-parts, built from primary filings and dated peer compilations. Multiples are anchored to full-cycle and peer regimes, never to the stock's own recent price history.
Structure is priced separately. Where a security's structure matters as much as the business, as with dual listings, the wrapper and the underlying are valued on their own terms and the difference is said so.
