The 11 biggest companies on the Irish stock exchange

Some names you’ll probably know, and some you mightn’t – but, in terms of sheer value, here are the big boys.

WHEN WE HEAR about the day’s action on the stock exchange, we tend to hear about the same shares every day – “AIB down X, Bank of Ireland up Y”, and so on.

What would be easy to overlook is that these shares tend to be mentioned most frequently simply because they’re the ones that most people are likely to own – but not because they’re the biggest companies on the market.

In fact, there are companies that are worth significantly more than the ones you’ll hear about – and in some cases you might never even have heard of the companies being discussed.

Here’s our quick guide to the 11 most valuable companies whose shares are traded on the Irish Stock Exchange.

(Note that in many of the highest cases the shares are traded on Dublin as well as in other markets.)
