Martin Ebner, the vociferous financier who was once dubbed the Swiss George Soros, yesterday announced he had taken a stake in HSBC Holdings worth about GBP187 million (HK$2.37 billion).
Mr Ebner is considered one of the world's most formidable minority shareholders.
The businessman's BZ Group was one of the driving forces behind nationwide demands to deliver shareholder value and shake up Swiss industry.
Yesterday, Mr Ebner's principal investment vehicle - BK Vision, which holds the shares - said that the 0.4 per cent stake had been acquired in the first six months of this year, when HSBC's shares were being buffeted by the Asian financial crisis.
The company said its motives behind the acquisition lay more in the relatively cheap valuation of the group rather than any desire to start building pressure for corporate reform.
'HSBC has very good management, a clear strategy and good financing,' said Kurt Schildknecht, a director of BK Vision and one of Mr Ebners closest associates.
