Credit Suisse $4.2bn share sale and sweeping restructuring were supposed to regain the market’s confidence. Instead, more investors are betting against the bank.

Around $1bn, or 8%, of Credit Suisse stock and depositary receipts have been shorted, or borrowed and sold with the aim of buying them back for less later, according to data provider S3 Partners. That is up from less than 3% in early October, before Credit Suisse said it would sell new shares.
