SHARE prices on the Irish Stock Exchange have hit another all time high with the ISEQ index gaining 22.96 points to 2,606.55. The surge was in line with record performances in London and other international markets follow positive reaction to the US Federal Reserve decision on Tuesday to leave its key interest rates unchanged. International bond markets also performed strongly. The London stock market gained 25.2 points pushing the FT SE share index up to 3,935.7, while shares in Paris and Frankfurt also moved strongly ahead.
