IRISH shares were little changed for a fourth day, as a sell-off of some major stocks pushed the index marginally into the red.
By the close in Dublin, the ISEQ Overall Index was down 0.06pc, or 1.99 points, at 3,546.33.
The market, which has moved less than 0.2pc so far this week, looked like it would post a gain for most of the session, and it was only a late sell-off that pushed it into the red on the day.

Speciality baker Aryzta fell 1.46pc to €40.80.
No-frills airline Ryanair fell 1.4pc to €5.50. The European Union's top court ruled the carrier must pay passengers for expenses such as food and lodging after a flight cancellation due to a volcano eruption in 2010.

"So you are seeing good earnings being much better and bad earnings being really punished by the market – that's great for stock pickers."

Santander declined 3.5pc as Spain's largest lender set aside money for further loan losses in its home market. The bank reported fourth-quarter profit that missed forecasts by almost half.
Shell fell 2.8pc after Europe's biggest oil company reported fourth-quarter profit, excluding one-off items and inventory changes, that missed expectations.
