Société Bancaire Privée, a Geneva-based private bank, is being investigated by the Swiss Stock Exchange on suspicion of breaching listing rules.

A statement from the Swiss Exchange said SBP is being investigated on the grounds of a possible breach of Article 74a of the Listing Rules.

Aritcle 74a of the Swiss Exchange rules refers to disclosure of management transactions.

“The preliminary enquiries conducted by the SWX found that Art. 74a of the Listing Rules may have been infringed with regard to compliance with reporting deadlines,” said the statement.

A spokesman for the Swiss Exchange was not prepared to comment any further on the investigations nor when the Exchange will announce their findings on the investigation.

SBP has been listed on the Swiss Exchange since 1996. In the first week of March, SBP’s share price rose at least 40 per cent on speculation of major expansion plans. It has since traded at a premium to the Swiss Exchange and is up around 68 per cent since the beginning of the year.

Despite its listing, SBP is still majority owned by a number of very wealthy Italian families.

SBP could not be reached for comment.
