The reversal of large stock price declines: The case of large firms

Show all documents Testing the Efficient Market Hypothesis in an Emerging Market: Evidence from Forex Market in Mauritius The present study investigates the efficiency of the forex market based on the theory of the Efficient Market Hypothesis in Mauritius, a well-diversified and emerging economy in the African region. The technique used for analysis is firstly concentrated on the use of Augmented-Dickey Fuller ADF and Philips Peron PP unit root to test the weak-form of efficiency and secondly, the Johansen Cointegration Test, the Granger Causality Test and Variance Decomposition are utilized to examine the existence of semi-strong form efficiency in the Mauritian foreign exchange market. Results indicated that the unit root test tested by ADF and PP unit root test support the weak form market as it follows a random walk process. Secondly, the Johansen Cointegration test reveals that there is no long run relationships among foreign exchange variables.

Mynhardt, H. This paper examines the short-term price reactions after one-day abnormal price changes on the Ukrainian stock market. The original method of abnormal returns calculation is examined. We find significant evidence of overreactions using the daily data over the period Our analysis confirms the hypothesis that after an abnormal price movement the size of contrarian price movement is usually higher then after normal typical daily fluctuation. Comparing Ukrainian data with the figures from US stock market it is concluded that the Ukrainian stock market is less efficient which gives rise to opportunities for extra profits obtained from trading based on contrarian strategies.

In this study, we have attempted to seek evidence for weak-form of market efficiency for KSE Index. Index returns have been studied from 1st January, to 30th April, For further analysis, return series has been divided into these groups: , , , , , , , and For further analysis, Runs test has also been run on 20 companies return series for comparison purpose with the results of index return series. In addition, from KSE 30 Index, 20 companies return series based on the free-float of shares have also been analyzed through Runs test to check if increase in numbers of floating shares does increase the randomness in return series or not.

This paper studies the return reversals of exchange traded real estate securities using an arbitrage portfolio approach. Using the approach, we find that there exist significant return reversals in such securities. These return reversals could be exploited by arbitrage traders if trading costs can be ignored. However, the arbitrage profits disappear after deducting trading costs and taking into account the implicit cost of bid-ask spread. Thus, the real estate securities market is efficient at weekly intervals in the sense that one could not exploit the price reversals via some simple trading rules.

History of the Efficient Market Hypothesis

This paper examines the long-run reversal pattern for a sample of large U. The results from the analysis are largely consistent with the overreaction hypothesis and significantly greater in magnitude than those reported by previous studies. Six and 12 months after their initial price decline, the stocks of large firms earn approximately 4 and 12 percent in excess of what was expected, respectively.

Коммандер не отпускал. Она попробовала закричать, но голос ей не повиновался. Ей хотелось убежать, но сильные руки тянули ее. - Я люблю тебя, - шептал коммандер.  - Я любил тебя .

Вдруг она ощутила страшное одиночество. Стратмор увидел пятна крови на ее блузке и тотчас пожалел о своей вспышке.

 Нет, сэр. Какой номер вы набираете? - Сеньор Ролдан не потерпит сегодня больше никаких трюков. - 34-62-10, - ответили на другом конце провода.

В этот субботний вечер в Коридоре красного дерева было пусто, все служащие давно разошлись по домам, чтобы предаться излюбленным развлечениям влиятельных людей. Хотя Бринкерхофф всегда мечтал о настоящей карьере в агентстве, он вынужден был довольствоваться положением личного помощника - бюрократическим тупиком, в который его загнала политическая крысиная возня. Тот факт, что он работал рядом с самым влиятельным человеком во всем американском разведывательном сообществе, служил ему малым утешением.

Но перед его глазами был только Грег Хейл - молодой криптограф, смотрящий на него умоляющими глазами, и выстрел. Хейл должен был умереть - за страну… и честь. Агентство не может позволить себе еще одного скандала. Стратмору нужен был козел отпущения.

Она знала, что, пока ТРАНСТЕКСТ будет продолжать сжирать аварийное питание, она останется запертой в Третьем узле. Стратмор отпустил створки двери, и тонюсенькая полоска света исчезла. Сьюзан смотрела, как фигура Стратмора растворяется во тьме шифровалки. ГЛАВА 63 Новообретенная веспа Дэвида Беккера преодолевала последние метры до Aeropuerto de Sevilla.

Переключая передачи, Беккер мчался вперед между белокаменными стенами. Улочка имела множество поворотов и тупиков, и он быстро потерял направление. Он поднял вверх голову, надеясь увидеть Гиральду, но окружившие его со всех сторон стены были так высоки, что ему не удалось увидеть ничего, кроме тоненькой полоски начинающего светлеть неба.
