There are futures, options as derivatives in our capital-market including KOSPI200 futures and options. Unfortunately linked-manipulations between stock tradings and derivatives tradings happen too often. It is able to distinguish linked-manipulations from faked-normal stock tradings using some criterias ; real purposes of tradings, rationals manners or not, the scales of profits. These acts of unfair trades are increasing in our capital market and especially the occurrences of new type of unfair trades cast attentions on same fields for example manipulations disguising hedge in option trades etc. Crimes in manipulations fields are developing without halts. In order to cope with its revolutions, we should make clear standards to distinguish linked-manipulations from faked-normal stock-tradings by searching same case studies.
