Short seller targets Trafigura as Nyrstar bondholders prep swap

Iceberg Research, a short-selling research house which has published extensively on Noble Group, has turned its attention to Trafigura, claiming the commodities trading group has overvalued subordinated debt related to a Brazilian port it owns. Trafigura's bonds were down around two points on Thursday, just as bondholders in Nyrstar, a company it rescued, prepare to get paid out in new bonds issued by the commodity trader.
