Pareto Securities maintains a positive outlook on Star Bulk Carriers amid the market uncertainty imposed by the coronavirus pandemic.

The Oslo-based securities firm has upgraded its outlook on the New York-listed bulker owner's shares to "buy" from "hold", based partly on robust charter coverage through the third quarter.

"Star Bulk published an updated investor deck last week, showing that they have covered 45% of both the second quarter and third quarter at rates of around $11,500 per day," analyst Erik Havaaldsen wrote in a client note.
