* The capesize index .BACI shed 74 points or 4.1% to 1,753.

* Average daily earnings for capesize vessels .BATCA, which typically transport 150,000-ton cargoes such as iron ore and coal, decreased by $613 to $14,535.

* The panamax index .BPNI rose by 18 points to 1,208, marking a one-week high.

* Average daily earnings for panamax vessels .BPWT, which usually carry 60,000-70,000 tons of coal or grain, was up $161 at $10,873.

* Among smaller vessels, the supramax index .BSIS broke a 14-session losing streak, adding one point to reach 937.
