Dublin's ISEQ index has ended the week at a new record high of 9,222, up 131 points on the day and more than 3% this week.
This means almost €4 billion has been added to the value of shares traded in Dublin in the last week.
Banks were among the star performers today, with AIB jumping 75 cent to €22.70 and Bank of Ireland adding 59 to €17.34. Elan gained 31 cent to €10.81 after saying it had asked US regulators to approve use of its MS drug Tysabri to treat Crohn's disease.
The ISEQ's climb was in line with other European markets, which hit five-and-a-half-year highs after tame US inflation figures appeared to make more US interest rate rises next year less likely.
