"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.

"Modeling the correlation of assets returns volatilities across different markets or segments of amarket has practical value for portfolio selection and diversification, market regulation, and riskmanagement. This paper therefore evaluates the nature of time-varying correlation between volatilitiesof stock market and crude oil returns in Nigeria using Dynamic Conditional Correlation-GeneralisedAutoregressive Conditional Heteroscedasticity (DCC-GARCH) model. Results from DCCGARCH(1,1) model show evidence of volatility clustering and persistence in Nigeria stock marketand crude oil returns. The results also show that there is no dynamic conditional correlation in ARCHeffects between stock market returns and crude oil prices in Nigeria. The results further show thatthere is strong evidence of time-varying volatility correlation between stock market and crude oilreturns volatility. The findings will help shape policy-making in risk management and market regulationin Nigeria."

"We extend the persistence and pervasiveness of the presence of value effect to Indonesian stockreturns in the last two decades by utilizing data set that is relatively free of survivor bias and selectionbias. Our finding shows that value portfolios have been able to outperform growth portfolios.Furthermore, the presence of the effect as an asset pricing factor, along with the size effect, can significantlyexplain the returns of the aggregate equity mutual funds in Indonesia and unveil that theequity mutual fund industry does not provide sufficient risk-adjusted return to cover trading costs andfund expenses. Our proposition is that the equity mutual fund valuation will be better off to apply simplermodel shown in this paper to capture the value premium as opposed to the general applicationof traditional valuation method."

"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."

"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."
