This thesis investigates systematic liquidity risk and short-term stock price reaction to large one-day price changes. We study 642 constituents of the FTSALL share index over the period from 1st July 1992 to 29th June 2007. We show that the US evidence of a priced systematic liquidity risk of Pastor and Stambaugh (2003) and Liu (2006) is not country-specific. Particularly, systematic liquidity risk is priced in the London Stock Exchange when Amihud's (2002) illiquidity ratio is used as a liquidity proxy. Given the importance of systematic liquidity risk in the asset pricing literature, we are interested in testing whether the different levels of systematic liquidity risk across stocks can explain the anomaly following large one-day price changes. Specifically, we expect that the stocks with high sensitivity to the fluctuations in aggregate market liquidity to be more affected by price shocks. We find that most liquid stocks react efficiently to price shocks, while the reactions of the least liquid stocks support the uncertain information hypothesis. However, we show that time-varying risk is more important than systematic liquidity risk in explaining the price reaction of stocks in different liquidity portfolios. Indeed, the time varying risk explains nearly all of the documented overreaction and underreaction following large one-day price changes. Our evidence suggests that the observed anomalies following large one-day price shocks are caused by the pricing errors arising from the use of static asset pricing models. In particular, the conditional asset pricing model of Harris et al. (2007), which allow both risk and return to vary systematically over time, explain most of the observed anomalies. This evidence supports the Brown et al. (1988) findings that both risk and return increase in a systematic fashion following price shocks. / Yarmouk University, Jordan.

This thesis compares various attributes of the two stock exchanges that are currently in existence in the Czech Republic: the Rm-system Czech Stock Exchange and the Prague Stock Exchange. Detailed comparisons are made between various specifics of membership policies, trading routines, fees and indices at these exchanges and these are then related to the corresponding attributes at two representative foreign exchanges: the London Stock Exchange and the New York Stock Exchange. A principal question to be answered in the thesis is whether having two independent organizers of stock-market trading is beneficial to the investors and overall practical for the market of the size of the Czech Republic. The first, theoretical part of the thesis is focused on historical evolution and characteristics of the stock exchanges. In this part we give a general classification of stock exchanges, discuss in some detail the kinds of traded financial instruments, describe trading participants and elucidate the nitty-gritty of trading systems. The second, practical part of the thesis then examines detailed facts about individual stock exchanges in the order listed in the theoretical part with the emphasis put on the differences between the stock markets under study. Various representative data is collected in tables and/or recorded in charts and graphs. Particular distinctions between the stock exchanges are analyzed and the distinguished aspects are highlighted. The conclusion summarizes obtained results and finally answers, in the mild affirmative, the question whether it is beneficial to have the stock market in the Czech Republic served by two independent stock exchanges.
