Shares in ABB - Europe's second largest engineering firm - have slumped another 21 per cent to 1.6 Swiss francs.
The slide follows a 62 per cent collapse in ABB's stock yesterday after it issued a profit warning that prompted a number of ratings downgrades.
The group, which employs 150,000 globally and 6,800 in the UK, yesterday triggered fears it is on the brink of collapse.
It announced it was considering Chapter 11 bankruptcy protection for one of its US units because of the threat of asbestos litigation while also warning it will not meet profit margin forecasts this year.
