But even with a tailor-made derivative or OTC derivative which would be cheaper, perhaps insuring you against a relative fall in your portfolio against the index, you would still have the portfolio and the shares, but you would have protected yourself against the risks of a collapse.
Med et skræddersyet eller såkaldt OTC-derivat (derivat, som ikke omsættes på de regulerede markeder), som måske ville være billigere til at forsikre Dem mod et relativt fald i Deres portefølje over for indekset, ville De stadig have porteføljen og aktierne, men De ville have beskyttet Dem mod risikoen for et sammenbrud.
