Correction, 23 October 2026: An earlier version of this column said Mitsubishi UFJ Financial Group bought $199.4mn of Japan Real Estate Investment; the filings show a move from 5.00 per cent to 5.20 per cent, too small to value. It also took the Fast Retailing filings of 16 October, in which the founding family's companies reported their stakes one by one, for a $15.8bn sale by TY Asset Management, and its totals for 19 October and for the 30 days counted these errors; they are restated from the filings as now recorded.
