Sekhar told CNBC-TV18, "The investor should clearly hold on to Mercator Lines and buy on declines for a simple reason that apart from the Baltic Dry Index recovering Mercator Lines have exposure to other segments also such as rigs, dredging and coal mining also to a limited extent. The biggest positive in favour of Mercator Lines at this point in time is trading at 0.7 times price to book and on the back of aggressive expansion that it has done in the last three years the fruits of that will be visible over the next two years or so. So, I would clearly advice the investor to stay on in this stock and it can double over the next two years."
