Star Bulk Carriers co-chief financial officer Christos Begleris admits his company cannot guarantee consistent earnings in volatile markets.

But he told the Marine Money Ship Finance Forum in London on Thursday that the US-listed operation has a few ways of smoothing out rate troughs.

The CFO pointed to Ebitda of $200m in 2019 and $900m in 2021 as evidence of the huge swings that can be seen in bulker profitability.
