GAM shares jumped over 15% on Wednesday following a report the firm had held informal talks with potential buyers.
Shares in the asset manager rose 15.8% to CHF8.1 at around midday on Wednesday (10 October) after a Bloomberg report said the firm was talking with potential buyers for all or part of the business.
The news comes at a time when the asset manager is under increased pressure following the suspension of manager Tim Haywood on 31 July.
Haywood, who was the business unit head for GAM's CHF 11bn (£8.5bn) AUM unconstrained/absolute return bond strategy, was suspended after an internal investigation into issues relating to his risk management procedures and record keeping.
GAM subsequently announced it was liquidating the absolute return bond fund range on the back of high levels of redemption requests.
The firm said it has returned 87% of the cash to investors with the second round of liquidation payments starting on 24 September.
The share price has suffered since Haywood's suspension and is down more than half since its January high.
