Investing

Ideas from my coverage go into paper portfolios with a public record, mostly to hold myself to my own calls.

Where I look

Global equities

The US, Japan, Korea, A-shares and Hong Kong, with no home bias. I pick stocks bottom-up, then hedge out the market and the sector with index, sector-ETF or single-name shorts, so what’s left is the stock selection itself.

AI & semiconductors

The AI hardware chain: semiconductor materials, equipment and electronics.

Consumer

From drinks and snacks to collectible toys and outdoor brands.

Research tooling

Rebuilding the research workflow around AI: data, sources, tools and daily routines.
