I'm not entirely sure why the DBI is rising or why it is rising so rapidly. At 509 which I think was the low, (30 year low),just a few months ago, the number represented losing money for any shipper going to contract to move goods. This caused panic and new build orders to be cancelled and some shippers to warehouse vessels.
If nothing else, if the DBI stays near 1000 NM's dividend should be secured indefinitely. This should be attractive to longer term investors.
As well, Angeliki is looking like a genius here for scooping up several ships in foreclosure over the last few months.
