Analýza cenových odchylek a sledovacích chyb ETF fondů: Případ amerického trhu

i Abstract In this thesis, we present an analysis of pricing deviations and tracking errors of ETFs with regard to their focus. We deploy several panel data models estimated on a sample of 12 U.S. iShares ETFs divideded into three categories: broad market ETFs, dividend ETFs and sector specific ETFs and examine if the pricing deviations and tracking errors differs between the groups. We suggest, that dividend and sector specific ETFs tend to have bigger pricing deviations and tracking errors, however, we attribute it mainly to the higher expense ratios associated with them, rather than because of their focus.

Využíváme několik modelů panelových dat estimovaných na vzorku 12 iShares ETF fondů z trhů v USA rozdělených do tří kategorií: obecné ETF, dividendové ETF a sektorově zaměřené ETF. Docházíme k závěru že dividendové a sektorově zaměřené fondy mají větší cenové odchylky a sledovací chyby, nicméně připisujeme to zejména vyšším poměrovým ukazatelům nákladům které tyto fondy mají, místo jejich zaměření.

Click and detect: Versatile ampicillin aptasensor enabled by click chemistry on a graphene-alkyne derivative

Tackling the current problem of antimicrobial resistance (AMR) requires fast, inexpensive, and effective methods for controlling and detecting antibiotics in diverse samples at the point of interest. Cost-effective, disposable, point-of care electrochemical biosensors are a particularly attractive option. However, there is a need for conductive and versatile carbon-based materials and inks that enable effective bioconjugation under mild conditions for the develop ment of robust, sensitive, and selective devices. This work describes a simple and fast methodology to construct an aptasensor based on a novel graphene derivative equipped with alkyne groups prepared via fluorographene chem istry. Using click chemistry, an aptamer is immobilized and used as a suc cessful platform for the selective determination of ampicillin in real samples in the presence of interfering molecules. The electrochemical aptasensor displayed a detection limit of 1.36 nM, high selectivity among other antibi otics, the storage stability of 4 weeks, and is effective in real samples. Addi tionally, structural and docking simulations of the aptamer shed light on the ampicillin binding mechanism. The versatility of this platform opens up wide possibilities for constructing a new class of aptasensor based on disposable screen-printed carbon electrodes usable in point-of-care devices.Web of Scienc

Investing in technology companies

The diploma thesis is focused on the issue of investing in information technology companies solely on the American capital market. It is divided into two parts. The first part deals with the private market. It compares the situation with the financial bubble in 2000 and with recent developments. It describes the current situation from a legal and financial point of view. It works with the term "Unicorn" for companies with valuations exceeding $ 1 billion. The second part focuses on the stock market and describes the change in the market capitalization of technology companies in relation to fundaments that are created in the private market. The diploma thesis is suitable for investors who want to invest in this type of companies, but they do not have access to the private market and therefore their only investment option is with the entry of the technology company into the stock market. The author's contribution lies in describing the current situation in the technology companies market
