Abstract:

文章以上市公司定向增发解禁为背景,从利益冲突的角度检验了不同增发对象在解禁后交易动机的差异对解禁前分析师盈余预测乐观程度和准确性的影响。研究发现,定向增发股票解禁时,机构投资者出于抛售获利的动机向分析师施压,导致分析师在解禁前为其所持有的股票发布了更加乐观的盈余预测,而且这些乐观预测的准确性更低;而原股东在定向增发股票解禁后倾向于继续持有,分析师在解禁前没有发布乐观有偏的预测。进一步的研究显示,机构投资者即将解禁的股份占公司总股本的比例越高,在临近解禁日时,分析师对该上市公司的预测越乐观,准确性也越低。现有文献认为机构投资者对分析师的乐观倾向具有抑制作用,而文章的经验证据表明,机构投资者在涉及自身利益时会削弱这种抑制作用。
