Investors will ultimately reward shipowners that have installed exhaust-gas scrubbers on their ships, two US-based equity analysts believe.

But the two researchers — Chris Snyder of Deutsche Bank and Randy Giveans of Jefferies — arrived at different conclusions as to whether that reward has begun, after analysing data at TradeWinds’ request.

Snyder finds a correlation underway, with scrubber-using owners having outperformed others by 27% in the fourth quarter of 2019, ahead of the IMO 2020 sulphur cap that came into effect on 1 January.
