Brokerages Hold RMB55.98B of A-Shares at End-Q3, Down 27.49% QoQ

The sharper drop in value than in share count points to mark-to-market losses compounding outright reductions in exposure, so the retreat reflects both selling and weaker prices rather than a single cause. The concentration in pharma/biotech, basic chemicals and electronics shows brokerages' proprietary books remain tilted toward cyclical and growth sectors even as the aggregate footprint shrinks. Whether the reduced share counts signal a lasting pullback in brokerage balance-sheet participation in A-shares, or just quarter-end positioning, is the open question worth tracking in the next disclosure.
