The thesis mainly deals with sensitivity analysis of risk and return of portfolio in dependence on outer parameters during generating a stock portfolio. The theoretical section consist of description of risk in context of shares, the definition of characteristics of shares and portfolio, and the assumptions for modern theory of portfolio. Also the specifications of mathematical model, the model of quadratic programming and modified model are parts of this section. The modified model adds condition for maximal weight of shares. The practical section begins with statistical description of data, while the data consist of shares which are included in FTSEurofirst 100 index. Sensitivity analysis is made for two approches where we allow or disallow the short-selling. Consecutive part propose final portfolios for three types of investors.

ELECTRE methods: theory and applications
 Pieter, Michal ; Jablonský, Josef (advisor) ; Fiala, Petr (referee)
Multiple-criteria decision-making (MCDM) is a field of decision theory concerned with analyzing discrete sets of variables evaluated by multiple criteria. Facilitating decisions in such situations are several methods, among them a family known as ELECTRE. Using threshold values and the concept of outranking, they allow for improved modeling of the uncertain nature of real systems. This thesis sets out to describe all of the basic ELECTRE methods, as well as several of their modifications and further extensions and aims to do so with a sufficient level of detail and using precise mathematical language. It also presents key applications of said methods and reviews their implementation in software. Lastly, it introduces a brand new software, ELIA, developed as a part of the thesis. It allows users to solve practical problems using four of the basic ELECTRE methods.
