"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 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."

"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 article contributes to country specific result on the responses of sector stock indices to crudeoil price changes. Using linear and asymmetric models and by studying the association of crude oiland stock price, this article aims to explain about the short-term responses of Indonesian sector stockindices to crude oil price changes. Besides, we also try to figure out whether there are asymmetricresponses within. Our findings suggest that the strength and the sensitivity of this association varyacross sectors, and the effects are positive for all sectors. We also find strong significance of asymmetryreactions for Agriculture and Consumer Goods sector stock returns due to changes in crudeoil price."
