Hedge funds have been ploughing more cash into shipping investments as they bet on a recovery.
Figures from Symmetric cited by Reuters show activity being significantly stepped up in the fourth quarter.
Funds have pumped at least $675m into the industry on signs of improvement in markets.
“Shipping has been in a terrible trough for a number of years,” Chris Walvoord, global head of hedge fund research at investment consultant Aon Hewitt, told Reuters.
