Purpose This purpose of this study is to empirically investigate the investors overreaction and underreaction behaviours across the sectoral stock indices in the Indonesian stock market. Design/methodology/approach Nine weekly sectoral stock indices, comprising agriculture; mining; basic industry and chemicals; miscellaneous industry; consumer goods industry; property and real estate; infrastructure, utilities and transportation; finance; and trade, service and investment for the period 2009-2012 were analysed using the paired dependent sample t-test. To provide more insightful empirical evidence, the presence of market anomaly of investor’s overreaction and underreaction was examined on five observations with different vulnerable times. Findings The study documented that the overreaction anomaly was present among the winner portfolios in the entire sectoral indices. With the exception of the sectoral index of basic industry and chemicals on the loser portfolio, the study documented the presence of underreaction anomaly among all other sectoral indices in Indonesia. These findings implied that the investors might be able to gain significant profits investing their monies in the sectoral stock market in Indonesia by implementing the contrarian strategy. Originality/value Originality in this paper lies in the discussion of overreaction of investors in Indonesia where the stock market has great potential and has different characteristics and different problems from other regions.

This research empirically and comparatively examines the quality of conventional and Islamic banks’ asset management in Indonesia during the period 2009-2011. Four general conventional banks [i.e., Bank Mandiri Indonesia (BMI), Bank Rakyat Indonesia (BRI), Bank Central Asia (BCA), and Bank Nasional Indonesia (BNI)] and four Islamic banks (Bank Muamalat, Bank Syariah Mandiri, Bank Syariah Mega Indonesia, and Bank Syariah BRI) were, respectively, explored. Specifically, the purpose of this study is to compare the quality of the Islamic and conventional banks’ asset management with the CAMEL (capital, asset, management, earning, and liquidity) method. It also attempts to analyse the influences of the ROA (Return on Asset), TLTA (Total Loan to Total Assets), and OITL (Operating Income to Total Liabilities) on the quality of the banks’ asset management. The CAMEL method was used to evaluate the quality level of the banks’ asset management, while the multiple regression analysis was then adopted to explore the determinants of the quality of the banks’ asset management. The study documented that Bank Syariah BRI was the best performing bank, with the highest CAMEL score of 50.33, while Bank Mandiri Indonesia was the worst performer with the lowest CAMEL score of 26.33. As a group, the Islamic banks were found to have better rankings, i.e., positions 1, 2, 3, and 6, while the conventional banks were found in 4, 5, 7, and 8, respectively. The study proved that the Islamic banks have a better asset management quality compared to their conventional counterparts. The Islamic banks were also proved to be better able to withstand the risks, particularly the financing risk.

The purpose of the study is to investigate the effect of work stress, workload and work environment on job satisfaction and its impact on the employee performance of DPMPTSP Aceh. The sample of the study is 138 civil servants of the institution. Data collected by questionnaire, and structural equation model (SEM) is operationalized to analyze the data. The study found that work stress has a negative and significant effect on job satisfaction and employee performance. On the contrary, both workload and work environment have a positive and significant effect on job satisfaction and employee performance. Furthermore, job satisfaction has a positive and significant impact on employee performance. The existence of job satisfaction mediates the effect of workload and work environment on employee performance. Conversely, the variable doesn't mediate the effect of work stress on employee performance.

Organic products are products that are currently the main choice for consumers who care about their health. In addition, organic products also reduce the impact of environmental damage and are healthier than conventional products. However, in some previous studies that examined the model of attitudes and intentions in behavior of the organic product consumption has shown there are no consistent results yet.

The result shows that attitude and purchase intention was significantly affected by health concern, product quality and knowledge but not by environmental concern. Then, attitude was have a significant direct effect on purchase intention, and this significant result has an impact on actual purchase behavior, in which attitude and purchase intention significantly affected actual purchase behavior of consumers' toward organic product.
