  • Der Post-Earnings-Announcement-Drift (PEAD; auch SUE-Effekt genannt) ist die Tendenz der kumulierten abnormalen Renditen einer Aktie, für mehrere Wochen (oder sogar Monate) nach einer Gewinnveröffentlichung bei einer positiven Überraschung weiter zu steigen bzw. bei einer negativen Enttäuschung weiter zu fallen.

  • 在经济学和会计学中,盈余惯性(post–earnings-announcement drift,PEAD)是一种在财务公布后的数周甚至数月内,仍然向超额回报方向连续获取的趋势。 通常认为公司的财务现状被公布后,信息应当很快被投资者消化并反映在市场价格中。然而,长久以来被注意到,实际情况并非如此。对于那些获得了季度性较高利润的公司,他们的超额资产回报倾向于在公布盈利额度后向该方向再“漂移”至少六十天。类似地,报告较差的公司同样倾向于向不利方向漂移同样长的时间。这种现象被称为盈余惯性。 该现象首先由Ray J. Ball和P. Brown在《会计学期刊》的“An empirical evaluation of accounting income numbers”一文首先描述。该文发表于1968年秋季,pp. 159-178。作为一种主要的盈利异常,这种健壮的现象反驳了效率市场假说(Efficient-market hypothesis)。PEAD也因此成为金融市场最为深入研究的现象之一。 (zh)
