Market efficiency theory stated that stock prices reflect all information in the market. There are 3 different level of market efficiency: weak form, semi-strong form and strong form. When a market is in the state of weak form, there is no investor can gain abnormal return using past information. Calendar effect that is Day of the Week, January Effect and Turn of the Month is anomaly in the stock market that opposed the efficiency market theory. The purpose of this study is to examine the Calendar Effect in Indonesia Stock Exchange during 2016. This research use daily stock price data in LQ45. Using the OLS regression with 5 dummy variables, the results showed that trading day had an effect on stock return where negative return occurred on Monday but not significant. The positive return occured in the following days and the highest return occurred on Wednesday. It can be concluded that the first hypothesis of Day of the Week phenomenon is supported. OLS regression with  1 variable dummy for return in January and 0 otherwise, the result shows that the coefficient is negative and insignificant so it can be concluded that January Effect is not supported. Third hypothesis, Turn of the Month, result shows positive and significant coefficient at level 1%. It means the stock returns in 5 trading days at the end of the month and 2 trading days at the beginning of the month are higher than in other days.

This study uses the event study methodology to explore semi-strong form market efficiency in the context of low levels of trading activity. Covering six frontier stock markets, it investigates stock price reaction to major national news events that include natural disasters, parliamentary elections and credit rating reviews and the international events such as international terrorist incidents, major events surrounding the 2007/2008 sub-prime mortgage crisis and the United Kingdom’s referendum on membership in the European Union (Brexit). The results of the event studies, which feature a correction for low levels of trading activity, show that in sharp contrast with more actively traded markets, stock prices on markets with relatively low levels of trading activity did not react to the vast majority of major news events, and only tended to react to rare events with major consequences. Usually, where stock prices reacted to a news event, the reaction was significantly delayed, which is inconsistent with semi-strong form market efficiency. The implication is that low levels of trading activity may be associated with semi-strong form inefficiency, and stock prices in such markets may not fully reflect all relevant available information, and may be of limited value to a variety of decision-makers.

Crude oil is the strategic commodity whose market has become the biggest commodity market in the world over the past 40 years. The main actors in the market, such as producers, refiners, financial institutions, and individual traders are interested in recognizing some trends, patterns or anomalies in performance of oil prices and returns, they could benefit from. Such anomalies among others are calendar effects, for example the day-of-the week effect, the month-of-the year effect, holidays effect or the turn-of-the month effect. Either the calendar effects are observed for stock prices, or for commodity prices, they make the markets inefficient. According to classical Fama’s definition: a market in which prices always fully reflect available information is called efficient. However, there are 3 types of market efficiency: weak-form efficiency, semistrong-form efficiency, strong-form efficiency. The weak-form market efficiency is tested the most often. There are several tools used for its verification, for example: some statistical tests (unit root tests, autocorrelation tests, variance ratio tests), long-run relationships and correlation analysis, calendar effects analysis. Our previous research focused on searching for calendar effects in the market of crude oil (Górska, Krawiec 2015), shows the existence of the-day-of-the week and the month effects. It may imply market inefficiency. That is why the present paper is aimed at further testing weak-form market efficiency. The empirical data covers daily closing prices of crude oil in USD per barrel from 2000 to 2015 and includes, both West Texas Intermediate (WTI) and Brent quotations. Having calculated their logarithmic returns, we apply the following tests: runs test, variance ratio, autocorrelation test.

This paper examines the efficiency and integration of the Indian stock market. The weak form of efficiency has been tested by studying the stationarity characteristics of theMSCI Stock Price Index of India. For testing the semi-strong form of efficiency and integration of the Indian Stock Market with the macro phenomenon of emerging stock markets of the world, the causality between the MSCI Stock Price Index of India and the MSCI EMF Index has been studied. The results point out that the Indian Stock Market is efficient in its weak sense. However, the same is not true for the semi-strong form of market efficiency. Therefore, the utility of a forecasting model having the macro phenomenon (MSCI EMF Index in the present case) as a forecasting variable cannot be ruled out.

One of the highly controversial issues in the area of finance is “Efficient Market Hypothesis”. Efficient Market Hypothesis states that, “In an efficient market, all available price information is reflected in the stock prices and it is not possible to generate abnormal returns compared to other investors.” A lot of studies conducted previouslyto test the Efficient Market Hypothesis, confirmed the theory until recent years, when some academicians found it to be non-applicable in financial markets. According to them, it is possible to forecast the stock price movements using Technical Analysis. The results of various studies have been inconclusive and indefinite about the issue. This study attempted to test the efficiency of FMCG Sector stocks in India in its weak form. For the study, closing prices of top 10 stocks from Nifty FMCG index has been taken for the 5-year period ranging from 1st October 2014 to 30th September 2019. Wald-Wolfowitz Run test has been used to test the haphazard movements in the stock price movements. The results indicated that FMCG sector stocks does support the Efficient Market Hypothesis and exhibit efficiency in its weak form. Hence, it is not possible to accurately predict the price movements of these stocks.

The objective of this research is to investigate the relationship between illiquidity and stock prices on the Tunisian stock exchange. While previous researches tended to focus on one form of illiquidity to examine this relationship, our study unifies three forms of illiquidity at the same time. Indeed, we simultaneously consider illiquidity as systematic risk, as a characteristic of the market, and as a characteristic of the stock. The aggregate illiquidity of the market is the average of individual stock illiquidity. The illiquidity risk is the sensitivity of the stock price to illiquidity shocks. Shocks of market illiquidity are estimated by the innovations in the expected market illiquidity. Results show that investors on the Tunisian stock exchange do not require higher returns when they expect a rise of market illiquidity, whereas investors on U.S markets are compensated for higher expected market illiquidity. In addition, shocks of market illiquidity provoke a fall in stock prices of small caps, while large caps are not sensitive to market illiquidity shocks. This differs slightly from results based on U.S. data where illiquidity shocks reduce all stock prices but most notably those of small caps. Robustness tests validate our findings. Our results are consistent with previous studies which reported that the “zero-return” ratio predicts significantly the return-illiquidity relationship on emerging markets.

AbstractThis study examines the ways political events can affect the stock prices of politically connected firms by studying one of the biggest corruption scandals in modern South Korean history, which led to the first-ever impeachment of a sitting president. We analyzed the stock returns of firms that donated money to foundations allegedly controlled by the president's confidante. We found that the abnormal stock returns of politically connected firms decreased when the president was removed from office. Using tick-by-tick stock price data, we were able to pinpoint the exact moments when the stock prices of firms that donated money fluctuated, as the president's fate was determined by the justices of the Constitutional Court.

An artificial stock market with agent-based model is built to investigate effects of different information characteristics of common factors on the dynamics stock returns. Investors with limited information capacity update their beliefs based on the information they have obtained and processed and optimize portfolios based on beliefs. We find that with changing of concerned information characteristics the uncertainty of stock price returns rises and is higher than the uncertainty of intrinsic value returns. However, this increase is constrained by the limited information capacity of investors. At the same time, we also find that dependence between returns of stock prices also increased with the changing information environment. The uncertainty and dependency pertaining to prices show a positive relationship. However, the positive relationship is weakened when taking into account the features of intrinsic values, based on which prices are generated.
