Shares in Carnival Corporation, the US constituent of the Anglo-American Carnival Corp & plc group, have failed to rally at the US market open despite unaudited quarterly earnings coming in significantly above expectations.

It posted an EPS of 25c a share compared  to the average market forecast of about $0.16c.

“The problem is that CCL (Carnival Corp & plc) also posted a raft of guidance for full-year 2015, including Q3 2015 non-GAAP EPS of $1.56-$1.60, and FY non-GAAP EPS of $2.35 to $2.50, that looks somewhat off course, compared to consensus,"  said Ken Odeluga, a senior market analyst at Cityindex in London.

Shares in Carnival Corporation fell 0.9% to trade at $49.46 on the New York Stock Exchange on Tuesday morning local time, while Carnival plc, the UK based and London listed holding company, lost 0.2% to £32.80 by late afternoon local time.
