Marshall Wace, a London-based hedge fund manager part-owned by private equity giant KKR, has appeared on the radar as a Euronav shareholder.

On 13 March, the investor bought shares to bring its stake in the Belgian tanker giant to 5.1%, just above the mandatory reporting threshold.

A 4.1% stake consists of outright voting rights and the remaining 1% of equivalent financial instruments, Euronav said in a regulatory filing on Monday.
