Real Picture

The current study intends to empirically test a relationship between long-memory features in returns and volatility of Dhaka Stock Exchange market. As such, the study uses the ARFIMA-FIGARCH and FIPARCH structure for the daily data ranging from 15 December 2003 to July 31, 2013 of Dhaka Stock Exchange market index, i.e., DSE General Index (DGEN). The observed indication assembled from long-memory tests supports the occurrence of long memory in Bangladesh stock returns. The study aims at doing research work with long-memory data set, as it provides a superior strategy, as well as gives real picture with short-memory data set. Moreover, the backup indication for existence of long memory in both return and volatility denies the efficient market hypothesis of Fama (1970) that the future return and volatility values are unpredictable. Extra measures ought to be given for the smooth functioning of the Dhaka Stock Exchange market so that both individual and institutional investors can get congenial atmosphere to invest. Authors’ suggested that Bangladesh Bank must play vital role as share market of Bangladesh is dominated by banking shares and in case of other listed shares of the Dhaka Stock Exchange, market authority should deal with transparently and fairly so that the market can be transformed into strong efficient market. This requires suitable directives, groundwork, removing malpractices and also implementation of investors’ friendly decisions. Further, fiscal policy of the country should be pro investor friendly, as well as monetary policy should work as complementary towards investment at stock exchange market as suggested by the authors.

The paper attempts to investigate the validity of the Efficient Market Hypothesis and the existence of calendar effect on Indonesia Stock Exchange Market. Initially, this paper discusses types of EMH also the literature available regarding this topic. The sample of research is twenty one securities listed in LQ 45 Index on the Indonesia Stock Exchange Market (IDX), this paper applies non parametric tests which are Run test, Kruskal-Wallis test, Mann-Whitney test  parametric test which are series correlation test, One-way Anova test and independent t-test two sample. Based on the results of the test of this paper, it can be concluded that Weak Form Efficient Market exists in LQ 45 Index of IDX while Day of the Week Effect and Month of the Year Effect are not found to exist in LQ 45 Index of IDX. In conclusion, it is observed that the effect of stock prices for the sample companies on future prices is very meager and an investor cannot reap profits by using the historical share price data as the current share prices already reflect the effect of past share prices data.

Ghana Stock Exchange

This article studies the long memory behaviour of stock returns on the Ghana Stock Exchange. The estimates employed are based on the daily closing prices of seven stocks on the Ghana Stock Exchange. The results of the autoregressive fractionally integrated moving average-fractionally integrated generalized autoregressive conditional heteroskedasticity (ARFIMA-FIGARCH) model suggest that the stock returns are characterized by a predictable component; this demonstrates a complete departure from the efficient market hypothesis suggesting that relevant market information was only partially reflected in the changes in stock prices. This pattern of time dependence in stock returns may allow for past information to be used to improve the predictability of future returns.

The study examines the predictability of index returns on the Dhaka stock market within the framework of the weak-form efficient market hypothesis using historical daily returns for a period of 1st June, 2014 to 29th May, 2020. The Jarque-Bera statistics test explored the return distribution of Dhaka Stock Exchange is non-normal. The random walk hypothesis (RWH) was tested using autocorrelation test, runs test, unit root tests(Augmented Dickey-Fuller (ADF) and, Phillip-Perron (PP) test) and variance ratio test. The results explored that all tests rejected the random walk hypothesis required by the weak-form efficient market hypothesis. This provides empirical basis to infer that the DSE is inefficient at weak-form and stock return can be predicted. The rejection of the RWH on a daily basis is possibly an indication that the weak-form inefficient characteristic of the DSE is not sensitive to return frequency.

Share Prices

The advocates of the Efficient Market Hypothesis (EMH) theory postulates that share prices depict all the available information concerning its intrinsic worth. EMH espouses the Random Walk Theory i.e. future stock returns cannot be predicted based on past movement patterns. Contrary to that, there are believers of the Adaptive Market Hypothesis (AMH) who have questioned the adaptability of EMH and argues that market efficiency and investor’s risk perception varies across time, thus, stock returns can be predicted through active portfolio management. Various Studies have argued on market efficiency debate for developed markets, however, limited studies have examined the same for emerging markets such as Malaysia and Indonesia, which are most volatile among ASEAN-5 indices. Therefore, the primary objective of this study is to conceptualize the manifestation of efficient market hypothesis and investors’ risk perception in volatile markets of Malaysia (Kuala Lumpur Composite Index) and Indonesia (Jakarta Composite Index) by testing the 10 years (2010-2019) of daily, weekly and monthly data for the return predictability. The findings of this study will provide insight into stock market behavior to help investors to better strategize their portfolio investment positioning to reap the most efficient risk-based return.

The purpose of this study is to investigate how earnings announcement event affects stock returns at Karachi Stock Exchange (KSE). For this purpose we use the KSE-100 Index as our sample. We use the CAR Analysis to analyze the impact of earnings announcement over the stock returns around announcement dates. Our results suggest that KSE experiences abnormal stock returns around earnings announcement dates for the overall market and for different categories which indicate that efficient market hypothesis does not hold in Pakistani market and point out the presence of informational dissemination inefficiencies in the market.

Purpose: This empirical study investigates the anomalous behaviour and volatility in stock return of PSX-100 index of Pakistan Stock Exchange (PSX). Design/Methodology/Approach: The data is taken from January, 2006 to December, 2018 to detect variability and predictability of stock returns. ARCH and GARCH models are applied to check the volatility in stock returns using dummy variable. Findings: It is found that there exists positive and significant September effect in Pakistani equity market. The returns are high in the month of September than other months. The constant returns do not exist during the whole year so the efficient market hypothesis contradicts. Implications/Originality/Value: The Efficient Market Hypothesis is question mark due to volatility for mispricing the securities. The mispricing may have implications for undervalue or overvalue the securities and overall economic activity of equity – stock returns.

Measure Of Dependence

The Johannesburg Stock Exchange as an efficient market. Finality has not yet been reached on the question whether the Johannesburg Stock Exchange complies with the requirements of the efficient market hypothesis. The results of the research that are published in this article is therefore an attempt to make a contribution to the debate regarding the Johannesburg Stock Exchange as an efficient market. By way of serial correlations as well as runs tests an investigation was carried out into the behaviour of the prices of 94 quoted shares for the period 1970 to 1977. The results of the study give rise to the conclusion that the Johannesburg Stock Exchange does not statistically comply with the weak form of the efficient market hypothesis (the random walk hypothesis), as a measure of dependence between successive price changes was found. Seen from an economic point of view it is, however, doubtful whether investors could use this small degree of dependence between price changes to gain higher returns on share investments.Uitsluitsel met betrekking tot die mate waartoe die Johannesburgse Effektebeurs aan die vereistes vir 'n rasionele mark voldoen, is nog nie verkry nie. Die resultate wat in hierdie artikel voorkom is daarom 'n poging om 'n bydrae in die debat rakende die Johannesburgse Effektebeurs as 'n rasionele mark, te maak. 'n Ondersoek na die markpryse van 94 genoteerde aandele vir die periode 1970-77 is deur middel van reekskorrelasiekoeffisiente en die lopietoets uitgevoer. Die resultate van die studie gee aanleiding tot die gevolgtrekking dat die Johannesburgse Effektebeurs nie statisties aan die swak vorm van die rasionele markhipotese (die willekeurige beweging van markpryse) voldoen nie, aangesien 'n mate van afhanklikheid tussen opeenvolgende prysveranderings gevind is. Uit 'n ekonomiese oogpunt gesien is dit egter twyfelagtig of beleggers hierdie afhanklikheid sal kan aanwend om hoer opbrengste op aandelebeleggings te bewerkstellig.

Detrended Fluctuation

This study conducts a systematic survey on whether the pricing behavior of cryptocurrencies is predictable. Thus, the Efficient Market Hypothesis is rejected and speculation is feasible via trading. We center interest on the Rescaled Range (R/S) and Detrended Fluctuation Analysis (DFA) as well as other relevant methodologies of testing long memory in returns and volatility. It is found that the majority of academic papers provides evidence for inefficiency of Bitcoin and other digital currencies of primary importance. Nevertheless, large steps towards efficiency in cryptocurrencies have been traced during the last years. This can lead to less profitable trading strategies for speculators.

Using a relationship between the moments of the probability distribution of times between the two consecutive trades (intertrade time distribution) and the moments of the distribution of a daily number of trades, we show that the underlying point process is essentially non-Markovian. A detailed analysis of all trades in the EESR stock on the Moscow International Currency Exchange in the period January 2003–September 2003, including correlation between intertrade time intervals is presented. A power-law decay of the correlation function provides an additional evidence of the long-memory nature of the series of times of trades. A data set including all trades in Siemens, Commerzbank and Karstadt stocks traded on the Xetra electronic stock exchange of Deutsche Boerse in October 2002 is also considered.

The Relationship

Sell in May and go away is a phenomenon of return anomaly that starts in May and lasts until October. These months are called the worst months of stocks. Conversely, the months of November to April are often referred to as the best months of the stock where a higher rate of return is achieved throughout the year. Although it has not been proven academically, this phenomenon has been mentioned by various media in Indonesia such as Kontan, CNN Indonesia, and Tempo Business which are predicted to correct the JCI throughout 2017.  The purpose of this study is to prove the phenomenon of sell in May and go away on the Indonesia Stock Exchange, and find out whether the average best return of the month is affected by the high return in January.  The results prove that even though the average returns increase in November-April was due to the high return in January, but there was no sell in May and go away on the Indonesia Stock Exchange. Under these conditions, the direction of the relationship between risk and return is the opposite that directs the Indonesia Stock Exchange to the efficient market hypothesis.
