What is 3D Investment Partners buying in Japan next?
3D Investment Partners (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.
Predicted next buys
P(this fund adds the name next), from the per-investor walk-forward model, out-of-sample AUC ~83%. A predicted probability is a statement about a filing pattern, never a claim the fund has bought a name or that you should.
