"This paper studies the impact of the stock market continuity on the returns volatility and on themarket efficiency in the Casablanca Stock Exchange. For the most active stocks, the trading mechanismused is the continuous market which is preceded by a call market pre opening session. Resultsobtained concerning return volatility and efficiency under the two trading mechanisms show that thecontinuous market returns are more volatile than the call market returns and 50% of stocks studiedshow independence between variations."

"Ritter and Welch (2002) explain there are two types of IPO firms, namely higher quality firms and lower quality firms. This research propose the third type, namely bad IPO firms which manipulate and force IPO underpricing. Bad IPO firms are subset of lower quality IPO firms that force false signal as higher quality firms. The false signal was hidden by managing post-IPO trading. Trading management are indirectly funded by using balance sheet cash. Hypothesis testing with the empirical model 1 was to confirm the role of CashRatio as the moderating variable that interact DER to affect IPO underpricing which originally was not. The findings support the predictions that interactive variable DER*CashRatio affect IPO underpricing. A managed trading had a non negative profits constraint so that selective post-IPO trading was conducted to cause trading imbalance observable as skewed trading volume (Skewness). Subsequent tests with the empirical model 2 was to confirm the role of Skewness as the moderating variable that interact VolRatio to affect post-IPO stock return (RGM) which originally was not. The findings support the predictions that interactive variable LnVolRatio*Skew affect RGM. Both findings confirm this research predictions on the possibility of manipulated IPO trading in Indonesia IPO 2009-2012."

"In this paper, we analyze the empirical relationship between stock return and trading volumebased on stock market cycles. Using daily data for Jakarta Composite Index (JCI) closing price andtrading volume from 2010 to 2014, we identify the bull and bear phases, then we analyze the return–volume relationship in both contemporaneous and dynamic context. We find that (1) there is a positivecontemporaneous return–volume relationship in both bull and bear markets, which is only significantin bull markets; (2) no evidence of asymmetry in contemporaneous relationship is found; and (3)there exists a positive unidirectional causality from stock return to trading volume. Our research hastwo implications. First, in the bull market, overconfidence may grow with long-lasting past successand there is also momentum or positive feedback trading. Second, stock return is able to forecasttrading volume. In addition, our findings are robust for different sample period and data frequency."

"In this study, we analyze contrarian and momentum strategies in periods associated with optimism or pessimism, and we compare them to the normal market sentiment condition. We evaluate the sentiment using the Arms adjusted index. Then, using the vector autoregressive test, we analyze the relationships among sentiment, stock returns, excess returns, and volatility. The results show that the formation of a short-term portfolio in one- and three-month periods of optimism and pessimism do not create additional returns and results in losses. In addition, the outcomes indicate that combining normal market sentiment with behavioral finance strategies increases performances, with more significant results seen using contrarian strategies compared to momentum strategies."

"The Indonesia Stock Exchange has really concerned about improving stock market quality thesedays. One of its effort is implementing pre-closing trading session. It refers to Decision of the Boardof Directors of The Indonesia Stock Exchange Number Kep-00399/BEI/11-2012, regarding Amendmentto Rule Number II-A concerning Equity-Type Securities Trading. The rule is effective on 2ndJanuary 2013 and Indonesia Stock Exchange has implemented it since that date. The purposes ofpre-closing implementation are to mitigate marking the close, which is the practice of buying securityat the very end of the trading day at a significantly higher price than the current price of the security,and to improve market quality. This paper attempts to veryfy whether the impact of pre-closing implementationto price efficiency is positive or not. The result shows that the pre-closing implementationhas positive impact to price efficiency. It reduces the return volatility and market manipulation at theclosing time which also means that the pre-closing implementation has effectively improved marketquality in the Indonesia Stock Exchange."

"Following the blueprint of the ASEAN integration 2015, the integration of the financial marketsin this region will increase. This study investigates the existence of a volatility spillover from the Singaporeanstock market into Indonesia, including its transmission pattern. Singapore, as an advancedcountry in the ASEAN region, has played an important role as the information leader in the market ofthis region, so that it is very possible that the shocks in the Singapore?s stock market will be transmittedto another stock market in this region. Using TGARCH (1,1) model specification regarding thedata of the daily return of the Indonesia market index (IHSG) for the period of January 2008 ? August2012, it is observed that the shock that took place in the Singapore stock market is immediately transmittedto the Indonesia stock market with two important asymmetric patterns. The transmission ofthe shock from the Singapore stock exchange becomes stronger when this market (1) experiences anegative return, and (2) is in the bearish phase."

"Studi pada karakteristik risiko dan return telah mendapat perhatian yang besar. Beberapa studi pada literatur keuangan perusahaan telah menguji apakah risiko default memiliki pengaruh terhadap return saham perusahaan, akan tetapi hasilnya seringkali bervariasi dan menjadi perdebatan. Penelitian terdahulu memperoleh hasil empiris yang bervariasi karena mengacu pada indikator risiko default dan sample dari pasar ekuitas yang berbeda. Tujuan utama dari penelitian ini adalah untuk mengevaluasi pengaruh risiko default terhadap pengembalian ekuitas menggunakan data yang diambil dari perusahaan-perusahaan non-keuangan pada Indeks Harga Saham Gabungan (IHSG) di Indonesia untuk periode penelitian 2008-2017. Penelitian ini menggunakan model Merton (1974) seperti yang dilakukan Vassalou & Xing (2004) untuk membangun proxy dari risiko default. Kelebihan dari model ini adalah mempertimbangkan volatilitas pada asset perusahaan dalam mengestimasi risiko default. Dengan metode ini, perusahaan dapat memiliki tingkat ekuitas dan hutang yang serupa, namun bisa saja memiliki probabilitas default yang sangat berbeda. Hasil penelitian menunjukkan bahwa risiko default memiliki pengaruh yang positif dan signifikan pada pengembalian ekuitas.

The study of the characteristics of risk and return has received great attention. Several studies in finance literature have tested whether default risk has an influence on company's stock returns, but the results are often conflicting. Previous research derive varying empirical results because they refer to default risk indicators and samples from different equity markets.

The main objective of this study is to evaluate the effect of default risk on stock return using data taken from non-financial companies on the Indonesia Composite Index (IDX Composite) in Indonesia for the 2008-2017 research period.

This study uses Merton (1974) model as done by Vassalou & Xing (2004) to build a proxy for the risk of default. The advantage of this model that it considers the volatility of company's assets in estimating default risk. Companies can have similar levels of equity and debt, but possibly have very different default probabilities. The results of the study show that default risk has a positive and significant effect on equity returns."

"This paper empirically examines the efficient market hypothesis (EMH) in the Islamic stock marketnamely Jakarta Islamic Index by emphasizing on the random walk behavior and nonlinearity. Inthe first step, we employ Brock et al. (1996) test to examine the presence of nonlinear behavior inJakarta Islamic Index. The evidence of nonlinear behavior in the indices, motivate us to use nonlinearESTAR unit root test procedure recently developed by Kapetanios et al. (2003) and Kruse (2011).The nonlinear unit root test procedure fail to rejects the null hypothesis of unit root for the indices,suggesting that Jakarta Islamic Index characterized by random walk process supporting the theoryof efficient market hypothesis. In addition, Lumsdaine and Papel (LP) test identified significant structuralbreaks in the index series."

"This paper investigated the impact of seasoned equity offerings (SEO) on stock return of listedcompanies in Ho Chi Minh City market using the method “event study” which has been basicallyformed by Campbell, Lo, and MacKinlay (1997). The sample includes 332 SEOs from 2007 to 2010.The main findings show evidence that the Ho Chi Minh City market was not efficient in terms of thesemi-strong form because the price has increased significantly on the ex-right date, day 0. In an oppositeway, the market also reacted significantly negatively from T-4 to T-2. There are some significantimpacts of timing on issue methods – equity right issues were in priority for favorable time and issuesas “dividend by stocks” were chosen during unfavorable time."
