What is Effissimo Capital buying in Japan next?
Effissimo Capital (SG) discloses its Japanese stakes under Japan’s own regime, EDINET large-shareholding reports (大量保有報告書), the side a US 13F is blind to. Japan is also the one market where a prediction is checkable almost immediately: the report is due within about five business days of crossing 5%, not the US 13F’s 45. Research, not investment advice.
