British investment firm Montanaro Asset Management has boosted its holding in Clarksons.

Montanaro, founded by chairman Charles Montanaro in 1991, has disclosed a stake of 912,000 shares, giving it a 3.01% holding in the world’s largest shipbroker.

While its previous holding was not disclosed in a filing today, data from Bloomberg shows Montanaro had been the 11th largest shareholder in the London-listed company with below 2% of the stock.
