Schroders rises in volatile market They argued that Schroders" drive to attract institutional business had "clearly paid off," as the group has seen strong inflows, and that its £424m acquisition of Cazenove Capital, due to complete next month, could help lift operating margin at the private banking division. Gold producer Petropavlovsk, off 7 at 90p, was once again dragged lower by the fluctuating yellow metal price. There has been concern about the miner's exposure to the recent gold sell-off, although the company moved to reassure investors earlier this month by saying its hedging arrangements would help it operate within its banking covenants. Blinkx fell as much as 8.5pc before recovering some ground to close 3p, or 2.7pc, cheaper at 109¼p. Autonomy sold its entire stake of 45.7m shares in the online video search group on Tuesday, and Blinkx shares have fallen 13.3pc since then. Although the majority of shares are thought to have been placed with blue-chip institutions, one theory doing the rounds was that some had gone to hedge funds hoping the sale would remove an overhang from the stock. When Blinkx did not rise, as had been expected, they sold down their holdings, putting further pressure on the shares, or so the yarn went.
