Despite a rally from financial stocks, the Irish market closed down 3.1 per cent today, as drugs manufacturer Elan lost a third of its value.
In a day when domestic news weighed heavily on the Iseq, the index fell by 143.18 points to close the day at 4,441.86. Better than expected results from AIB saw financial stocks rally, but Elan fell by 31.8 per cent, or by €6.54 cents to €14.02, after detailed clinical trial results for its new Alzheimer drug proved mixed.
The decline in Elan's value saw it toppled from its position as the largest stock on the Iseq index in terms of market capitalisation, and it is now the third largest stock.
