Well this year investors were feeling much more confident after the head of the International Monetary Fund, Christine Lagarde, said the IMF is much more upbeat about the US economic recovery.
Meanwhile, a list put together by Justin Urquhart Stewart of Seven Investment Management shows the US Nasdaq market in the top ten performers of 2013, with a year to date return of just over 33%.
Ireland's stock exchange is also in the top ten, with growth of 35%. Other countries in the list include Zambia, Pakistan, Iceland, and topping the list - Venezuela - with a year to date return of 452%.
“What you saw there (in Venezuela) was the fear after the death of Hugo Chavez, there was ludicrous growth based but it was not really based on anything” said Mr Urquhart Stewart.
“But when you sit there and look at your own exchange, up 35%, that’s a remarkable turnaround”, he said.
“You look at all the ones people had written off for the year; whether it was Greece, Nigeria, Ireland, Zambia; those are fantastic returns overall.”
Mr Urquhart Stewart said the growth on the ISEQ represented greater economic confidence in the country, along with a rise in inward investment here.
