Shipbroker shares fly on Iran war windfallClarksons profit for the year would be "materially ahead" of estimatesShares in Clarksons climbed as much as nine per cent on Monday, after the ship broker revealed a record performance in the first half of the year and told shareholders to expect full-year results “materially ahead” of expectations. The group’s board also hiked its dividend from 33p to 35p, in a move that marks the 24th consecutive year of it raising shareholder payouts. “We expect the full year performance of the group to be materially ahead of market expectations.” Clarksons’ core shipbroking and investment banking divisions enjoyed record trading after ships were forced to re-route and make longer voyages. Clarksons has previously said the pay package is “established practice in shipbroking”, and that it had helped the group become the undisputed market leader globally.
