While the shock of Donald Trump's election has been bad news for stock markets in general this morning, one Irish firm has seen its shares soar to a nine-year high.

CRH, the largest producer of asphalt and third-largest producer of construction aggregates in the US, would certainly benefit if President Trump stays true to his promise to increase infrastructure spending. The US accounts for around 60% of the FTSE 100 group's profits, with 40% of that directly exposed to infrastructure.

Shares are up roughly 6% on both the Irish Stock Exchange and London Stock Exchange so far this morning.

It has been enjoying a bounce for some months already, as it was named in the media as being among the favourites to build Trump's wall to keep Mexicans out of the US.

The Dublin-based building materials giant rejoined the Euro Stoxx 50 in September, two years on from falling out of Europe's leading blue-chip stocks index.

The country's largest publicly-quoted company previously revealed it is targeting full year earnings in excess of €3 billion.
