I helped start an organisation which builds data science models for the shipping and commodity markets, and has had great success trading on the results of those models.
Within most shipping companies, there continues to be a significant hubris amongst charterers of "I know what I know" - a lot of people who have worked for decades in the industry and still trust their gut instinct over anything else.
As a result, since so few decisions are significantly data-driven, it's actually not that complex to build predictive models that take advantage of arbitrage opportunities in the market.
