Identifying Ineffective Monitors From Securities Class Action Lawsuits, Chi Shen Wei, Lei Zhang

Research Collection Lee Kong Chian School Of Business

We identify “ineffective” institutional monitors based on the prevalence of occurrences of securities class-action lawsuits in their overall portfolio. We find that firms with a higher representation of such institutional investors among the firms’ large shareholders have a greater likelihood of future litigation and experience more negative market reactions upon such litigation filings. These firms exhibit other unfavorable governance outcomes including poorer acquisitions and lower CEO turnover-performance sensitivity. We find suggestive evidence that ineffective monitoring may be a result of higher operational risk.
