Goldman Sachs has unveiled seven of its top trading ideas for investors next year, including selling protection through credit derivatives on Sweden, shorting crude oil futures and going long on the securitised bonds of US agency Fannie Mae.

In its global economics weekly report today, Goldman Sachs, which said its outlook for 2009 is "fairly gloomy", suggested seven trades that represent "the strategic ideas that we think have high-return potential and reflect our major macro thematic views".
