The Impact of Earnings-Announcement Timing to Technical Analysis Signal: The Case of Indonesia

Abstract

This study discusses about technical analysis signal and earnings-announcements timing. Technical analysis signal is used to capture price reaction around earnings announcements. Technical analysis is selected because it is competing information to fundamental information (Flanegin and Rudd 2005), especially in emerging market (Fifield et al., 2005). The longer reporting lag will result a tendency of bigger information leakage which make price reaction before announcements are stronger. That reaction produces a reliable technical analysis signal. By using Indonesian stock market data, the results show that (1) technical analysis signal generate bigger (lower) return for late (earlier) reporting, and (2) reporting lag positively affect to the performance of technical analysis signal that emerge before annual earnings announcements, especially in “buy signal” sample. These findings also indicate a tendency of bigger information leakage for companies that delay earnings announcements. This study contributes to build a bridge between technical analysis and earnings-announcement timing studies.
