I love the container shipping industry and the ways in which it behaves. There is some predictability to it and it provides good material to study business strategies employed in a highly commoditised market. It is not a very adventurous industry.
While everybody watches everybody else, all of them watch the biggest one and try to copy their moves. After the trend-setter moves, the other carriers, more or less, fall in line copying business model modifications of the first mover.
