In this paper is considered the issue of the portfolio of contracts for differences (CFD). As far as the standards of contracts traded on the stock exchanges are precisely defined and treated in such a manner that the investor in case of adverse developments for him on the market have the ability to complete the required margin, so transactions on the over the counter (OTC) market do not give an investor such the comfort and can result in an immediate closing open positions with significant losses for the investor. Open CFD positions offered in the OTC market are continuously monitored in terms of fulfilment of the required security deposit (margin) and the investor is responsible for maintaining the necessary assets to fully cover the market risk. Creating a CFD portfolio investor faces a dilemma, what proportion of the funds allocated to the opening position, and which of them leave as a hedge against market risks. The Problem is so complex that many of the CFD is exposed to currency risk. Appropriate funds intended to cover unrealised losses has to secure against a ineffective margin call to supplement the security deposit and unfavourable for the investor closing his position. The work discusses the various measures of market risk exposure used by reputable financial institutions offering contracts on exchange differences on the over the counter market. In addition, proposed several measures to support the portfolio structure of the CFD, taking into account market risk.

Both the prospect theory as well as the cumulative prospect theory are aimed at explaining the way the decision-maker see and evaluate risky decisions. They allow for the explanation of some inconsistency between observed decision-makers behaviours and axioms of the expected utility theory. For years financial aspects of cumulative prospect theory are the subject of many research studies. The purpose of the paper is to review some issues connected with the cumulative prospect theory and its application to financial market. Presented papers concern issues related to the value functions, concept of loss aversion and the construction of portfolio selection models with some simplifying assumptions. In our paper we also present observed in real life, but often mysterious, behaviours of investors, who evaluate investment choices relative to some reference point, feel loss aversion and revalue objective probabilities.
