Credit Suisse Group (CS) said Thursday it has adapted well to a changed market environment, unlike many of its peers around the world, who are still suffering from the financial crisis and struggling to adjust.

"We can't control market volume and margins. But what we have done is significantly increase our market share," Paul Calello, Chief Executive Officer of Credit Suisse's Investment Bank, told Dow Jones Newswires on the sidelines of the World Economic Forum here.
