Information of 83 right issues from 2006 to 2012 combined with the standard event study methodology has been used for this purpose. Findings reveal statistically significant abnormal returns on the announcement and surrounding dates. Sectoral decomposition of daily abnormal returns shows that textile sector provides the maximum abnormal return while banking sector delivers the least. The results of this study imply that DSE is not semi-strong form efficient with respect to past information on right issue announcements. Also information leakage before the announcement of right issues raises serious questions against efficiency in regulation and effectiveness of supervision in DSE.

We perform the investigation on weekly data of 25 mutual funds for the period of May 16, 2010 to April 28, 2016. To serve our objective, we tested both selection and market timing skills of the fund managers. We have used six measures; average return, Sharpe ratio, Treynor ratio, Information ratio, Jensen’s alpha and M square; to confirm the selection skill of fund managers and found no selection skill persistent to most of the fund managers (excluding Aims 1st M.F, ICB AMCL 2nd NRB M.F. and 6th ICB M.F.). In addition, the negative values of alpha indicate that fund managers become not only failed to add value to their portfolio, but also pool wrong assets which hurt the return resulting negative profit. On the other hand, we have employed two popular methodologies; Treynor and Mazuy [24] and Henriksson and Merton [10]; to test the market timing skill of fund managers and found no market...

This study uses monthly data from DSE All Share Price Index (DSI) for the period of 1987 to 2012. Under the hypothesis rational investors offsets taxable income against the capital losses to realize the losses at the end of the tax year which eventually causes significant positive returns in January or July as the tax selling pressure ends after the fiscal year. Empirical results do not support the tax-loss selling hypothesis as an explanation for the high June return at the end of the tax year in Bangladesh.

The goal of this paper is to measure the impact of changing margin requirement on stock returns' volatility in Dhaka Stock Exchange (DSE). The impact of margin requirement on stock price volatility has been extensively studied with mixed and ambiguous results. Using daily stock returns, we found mixed evidence that SEC's margin requirements have significant impact on market volatility in DSE.

Bangladesh has started its journey to get her exchanges demutualized in 2011. The purpose of this study is to examine the post-demutualization performance of the stock exchanges and offer some recommendations for stock exchanges in Bangladesh. In our study we examine the performance of three different stock exchanges that have already demutualized: Bursa Malaysia, Hong Kong Stock Exchange and London Stock Exchange. We found evidence that the performance of all the three demutualized exchanges have improved in terms of operational profitability and efficiencies along with governance scale. We have also identified some challenges associated with demutualization.

In spite of sensing very well about the mammoth economic cost attributable to hartal, politicians in Bangladesh are calling hartal repeatedly. This study mainly considers daily DSE General Index (DGEN) return and turnover (TK) for the sample period of June 1, 2010 to May 16, 2013 to examine the impact hartal on the stock market performance in terms of market return and turnover. Using dummy variable combined with linear regression analysis, we found evidence that hartal has little or no impact on the stock market performance.
