Cobas Asset Management, a top Spanish investment firm, has emerged as a new significant shareholder in Teekay Corp.

The Madrid-based company has built up a stake of 4.3m shares, or 5.07%, of the US-listed tanker company, according to a regulatory filing.

However, the Teekay shareholding is not Cobas Asset Management’s first investment in the crude tanker space or shipping for that matter.
