http://www.hec.unil.ch/cms_mbf/master_t ... 307.pdfThe idea of this strategy is actually quite simply; you trade say the equity against debt of a company. For example, if you expect a company to go bankrupt, sell equity and buy debt (simplistically speaking); because in default equity is worthless (at least theoretically) whereas debt-holders take over the company. Then the thing gets moer complicated because companies issue a lot of different debt and equity instruments and you can trade the whole lot.
