Investigation on the value relevance of accounting information: evidence from incorporated companies in the Singapore capital market
Investment Management and Financial Innovations Volume 13, 2016 Issue #3 pp. 9-21
Views: 1028 Downloads: 620 TO CITEThe purpose of this study is to investigate the relative, incremental and the systematic changes in value relevance of the accounting information. This study also attempts to investigate the effect of earnings management on the value relevance of accounting information. It basically uses Ohlson’s (1995) valuation model to test the conceptual framework.
The findings of this paper reveal that book value is more value relevant and incremental followed by earnings and, then, cash flow. Cash flow, however, performs a lesser valuation role. The results also show that combined book value and earnings are more value relevant than combined book value and cash flow. As a third contribution, the paper also finds that the value relevance of some accounting variables has increased over time, while others showed no evidence of their inclined or declined patterns in the value relevance of accounting information. Finally, the paper finds that earnings management has no effect on the value relevance of accounting information. Further analyses suggest that earnings management is opportunistic in the short run, but efficient in the long run, when firms are small or have high asset turnover -

Investment Management and Financial Innovations Volume 15, 2018 Issue #1 pp. 224-235
Views: 1335 Downloads: 155 TO CITE АНОТАЦІЯThe aim of this study is to examine the sub-variants of price momentum strategies. The paper recommends which sub-variants post above average returns for Australian Stock Exchange. It also analyzes the return behavior of short-term momentum effect among sub-variants of price momentum strategies. It has been found that monthly price momentum strategies result in above average abnormal returns, whereas weekly price momentum strategies should be used in combination with monthly price momentum strategies. Trading volume-based momentum investment strategies should not be used at all.
