Having sailed through choppy conditions for much of the year cruise operator Carnival said third quarter revenues were more buoyant than anticipated, and responded by lifting full year 2009 earnings guidance to between $2.16 and $2.20 a share from a previous range of $2.00 to $2.10.Broker Charles Stanley thinks the company will hit the top end of the range when it announces full year figures on Friday, though earnings per share of $2.20 would still represent a fall from the $2.90 achieved last year.The slide in earnings can be attributed to a precipitous fall in ticket yields plus higher fuel costs. Performance in North America has been hit especially hard by the global recession with customers, unsettled by the employment picture, putting off bookings until the last minute - or not booking at all.In Europe, where the market is dominated more by those who have retired from work, the market has been a bit more resilient. Charles Stanley is predicting profit before tax of $1,765m, down from $2,377m last year, on revenue of $13,225m, down from $14,646m.Engineering firm Keller has the safety blanket of public infrastructure spending to offset a hard hit privately-financed construction market. The company is expected to confirm that it is on track to meet full year profit expectations. On the economic front, public sector finance data for the UK is due to be released.
