Clarksons shares have enjoyed their hottest streak since the turn of the millennium after a selldown of stock by former RS Platou investors took more shares into the market.

London-listed Clarksons is up by one tenth today, continuing a three-day march that has seen the stock rise more sharply than at any time since 2000, according to Bloomberg data.

Analysts are attributing the trend to the combined impact of the sale of just over two million shares previously held by one-time RS Platou investors and a week-long roadshow undertaken by management following the company’s annual results.
