"This research proposes a numerical approach in estimating the trend of behavior of this market. This approach is applied to a model that is inspired by catalytic chemical model, in terms of differential equations, on four composite indices, New York Stock Exchange, Hong Kong Hang Seng, Straits Times Index, and Jakarta Stock Exchange, as suggested by Caetano and Yoneyama (2011). The approach is used to minimize the difference of estimated indices based on the model with respect to the actual data set. The result shows that the estimation is able to capture the trend of behavior in stock market well."

"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."

"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."

"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."

"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."

"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."

"Shari’ah stock market is also affected by many highly interrelated economic, social, political andother factor, same as the conventional stock market, the interaction between macroeconomic variablesand Shari’ah stock market creating volatility in the stock price as a response towards severalshocks. The sensitivity of Shari’ah stock market towards shocks happened related with the futureexpectation of micro and macro factor in one country which can be predict or unpredictable.There are six macroeconomic variables that used in this research; inflation, exchange rate, interestrate, dow jones index, crude oil palm price, and FED rate. Using vector error correction model(VECM), the result shows that domestic macroeconomic variables that significantly affect IndonesiaShari’ah compliance for long term, while for international macroeconomic variables the selectedvariable such as FED rate and Dow Jones Index are not significantly affected Indonesia Shari’ahcompliance both in short term and long term."
